Definitions

  • the invention relates to a compressed gas container specified in the preamble of claim 1. Art.
  • Such compressed gas containers are used to hold chlorine, ammonia or other gases. If in such a compressed gas container, the bleed valve or flange, which is bolted to the block flange, should be leaking, it may be due to leakage of compressed gas to a health hazard. Leaking pressurized gas containers of this type pose a major problem because they are usually very large. The usual volume is 500 to 900 liters. A leaking gas cylinder must be secured as quickly as possible. In the prior art, he is housed in a Berge tank, which must necessarily have an even larger volume than the male compressed gas container to be received. Such a Berge employer has a weight of up to 3 tons and must be brought on demand with heavy transport equipment. It is obvious that all this is very expensive.
  • document US-A-2 102 124 discloses a container for transporting liquids such as beer.
  • This container has a hood which has at the upper end an upwardly projecting neck and at the lower end an outwardly extending flange.
  • the hood is closed by a lid, which is provided with a sampling valve.
  • this container is provided with insulating caps, which are attached to the insulating sleeve of the container.
  • Document US-A-4 542 764 shows a railway pressurized gas container in which the manhole is covered by a cap. The part that it covers is accessible from the outside despite the cap, because the railway carriage can be unloaded, even if all the valves are completely covered.
  • Document US-B-6 390 1191 shows a railway tank car.
  • the manhole is covered by a lid in which valves are arranged. These valves can each be covered individually by an emergency cover. Over the thus secured valves a railway wagon hood is slipped, which protects the valves.
  • Document US 2002/148530 A1 shows a pressurized gas container with a safety cap.
  • the cap is welded to a flange cover covering the manhole.
  • the document US-A-1 827 574 deals with a method and apparatus for measuring the contents of tank trucks and the like. Valves and measuring devices are arranged in a space which can be closed by a lid. The space communicates through holes in the lid with the environment.
  • Document US-A-1 549 770 shows a railway tanker for gasoline and the like.
  • a cap with a handle is mounted on a lid which closes the opening in the tank.
  • the lid is a circular disc with a downwardly projecting flange.
  • the object of the invention is to provide a compressed gas container of the type mentioned in such a way that it can be secured in the event of a leak in a simple manner.
  • the pressurized gas container according to the invention is designed so that it can be closed in a gastight manner in the event of leakage by means of a solid emergency cap around its flange cover and above it.
  • the block flange radially outwardly of a coverable or covered by the flange cover area widened by a solid annular flange, which has a circumferential groove for receiving a sealing rib of the emergency cap in an upper end face.
  • the emergency cap which is kept separate from the compressed gas container in reserve, is placed on demand on the compressed gas container according to the invention and with its Screwed annular flange, wherein by means of the sealing rib and the receiving circumferential groove, a gas-tight connection between the emergency cap and the compressed gas container is made.
  • the emergency cap is used in the compressed gas container according to the invention so only when needed, if a leak has occurred.
  • the provided with the emergency cap compressed gas tank can be easily transported to the filler, for which there is no difficulty to fill the contents of the leaking gas cylinder in a proper compressed gas tank.
  • a heavy Berge practicer as is customary in the art and its complex transport to the place where there is a leaking gas cylinder, are made redundant by the invention.
  • the invention is easy to implement, because it is only necessary to create a compressed gas tank with a widened in outer diameter by an annular flange block flange and thereby provide a circumferential groove and screw options for the emergency cap.
  • the annular flange is provided with a ring of threaded holes for screwing to a mounting flange of the emergency cap, the emergency cap can be easily attached gas-tight to the removal valve.
  • the emergency cap can be coupled in a simple manner by inserting the sealing rib into the circumferential groove form-fitting and gas-tight with the compressed gas tank.
  • the emergency cap has a cylindrical wall and in one on the compressed gas container mounted state, the flange tightly enclosing radially, the smallest possible diameter of the annular flange can be realized.
  • the annular flange outside at a radial distance from the circumferential groove has a raised edge which radially surrounds the cylindrical wall with mounted emergency cap, and the emergency cap is protected and positively received by the annular flange.
  • the circumferential groove is arranged centrally between an outer periphery of the flange and an inner periphery of the raised edge of the annular flange, a secure seal is ensured by placing the emergency cap on the compressed gas container.
  • the attachment flange of the emergency cap is provided on an outer side of the cylindrical wall, the emergency cap can be easily produced as a forging, casting or welding part.
  • the mounting flange is provided on the outside of the cylindrical wall so that it has close axial distance from an axially adjacent end face of the raised edge of the annular flange at mountable emergency cap, can be achieved by a simple screw of two screw flanges firmly connect the emergency cap to the pressurized gas container.
  • the attachment flange of the emergency cap is a flange ring welded to the outside of the cylindrical wall
  • the emergency cap is a simple welded construction.
  • the compressed gas container is a specially designed for the widened through the annular flange block flange pressure gas container with a correspondingly enlarged upper opening of its wall, this compressed gas container and all parts to be mounted in its upper opening can be prepared in each case as a custom-made and then connect together to replace a conventional compressed gas tank entirely.
  • this compressed gas container and all parts to be mounted in its upper opening can be prepared in each case as a custom-made and then connect together to replace a conventional compressed gas tank entirely.
  • the pressurized gas container 10 has a wall consisting of a cylindrical shell 11, an upper elliptical bottom 12 and a lower elliptical bottom 13, which are welded together.
  • the wall has an upper opening into which an annular block flange 14 is welded.
  • the block flange 14 has a ring of threaded blind holes, in each of which an upwardly projecting stud 23 is screwed.
  • a circular top view of a flange lid 15 has a collar of through holes which are in register with the ring of threaded blind holes in the block flange 14.
  • the flange 15 is bolted to the block flange 14.
  • a flat seal 31 ensures a gas-tight seal between the block flange 14 and the flange 15.
  • the pressurized gas container 10 has a head ring 18 at the top and a bottom ring 19 at the bottom.
  • a protective cap 28, which has two handles 29, is arranged in the head ring 18.
  • a flat gasket 32 is arranged between each triangle flange 16 and the flange 15.
  • Each extraction valve 22 is provided below with a dip tube 21.
  • the dip tube 21 of the one take-off valve reaches into the upper region in the compressed gas container 10 for discharging the compressed gas in the gaseous phase
  • the other dip tube 21 of the other take-off valve reaches into the bottom region of the compressed gas container (not shown) for dispensing compressed gas in the liquid phase
  • FIGS. 1 and 2 The same reference numerals as in FIGS. 3 and 4 are used to simplify the illustration, provided that the same or corresponding parts are involved.
  • the pressurized gas container according to the invention which is designated overall by 10 ', has a block flange 14, which is not welded directly to the upper elliptical bottom 12.
  • the block flange 14 of the compressed gas container 10 ' is practically covered in its entire upper portion to its radially outer edge by the flange cover 15.
  • the block flange 14 of the pressurized gas container 10 ' is widened radially outside its area covered by the flange cover 15 by a solid annular flange 40 which is externally welded to the wall of the container, namely the upper elliptical bottom 12 at X' and inside adjacent to the covered area of the block flange 14 in an upper end face 42 has a circumferential groove 44 for receiving a sealing rib 46 of a total of 50 designated emergency cap.
  • the annular flange 40 is in the illustrated embodiment, a separate, welded to the block flange 14 part. Instead, the annular flange 40 could also be integrally formed with the block flange 14.

Abstract

The invention relates to a compressed gas container (10') comprising a block flange (14) that is provided on an upper opening in its wall (12), a flange cover (15) that is equipped with two extraction valves (22) being screwed onto said flange. The block flange (14) is extended radially beyond the region covered by the flange cover (15) by a solid annular flange (40), whose outer periphery is welded to the wall (12) of the container (10') and whose inner section lying adjacent to the region covered by the flange cover comprises a peripheral groove (44) in an upper front face (42), for holding the sealing rib (46) of an emergency cap. If required, said cap can be screwed onto the annular flange (40) if a leak occurs in the flange region of the container (10'). Compared to a conventional compressed gas container, the inventive container (10') is simple to produce, as the latter merely requires a larger flange region in order to provide it with the peripheral groove (44) and thus the screw construction for the emergency cap (50).

Description

Die Erfindung betrifft einen Druckgasbehälter der im Oberbegriff des Patentanspruchs 1 angegebenen Art.The invention relates to a compressed gas container specified in the preamble of claim 1. Art.

Solche Druckgasbehälter dienen zur Aufnahme von Chlor, Ammoniak oder anderen Gasen. Wenn bei einem solchen Druckgasbehälter das Entnahmeventil oder der Flanschdeckel, der mit dem Blockflansch verschraubt ist, undicht werden sollte, kann es durch Austreten von Druckgas zu einer Gesundheitsgefährdung kommen. Undichte Druckgasbehälter dieser Art stellen ein großes Problem dar, weil sie üblicherweise sehr groß sind. Üblich ist ein Volumen von 500 bis 900 1. Ein undichter Druckgasbehälter muß so schnell wie möglich gesichert werden. Im Stand der Technik wird er dazu in einem Bergebehälter untergebracht, der notwendigerweise ein noch größeres Volumen als der aufzunehmende undichte Druckgasbehälter haben muss. Ein solcher Bergebehälter hat ein Gewicht von bis zu 3 Tonnen und muß bei Bedarf mit schwerem Transportgerät herangeschafft werden. Es liegt auf der Hand, daß das alles sehr aufwendig ist.Such compressed gas containers are used to hold chlorine, ammonia or other gases. If in such a compressed gas container, the bleed valve or flange, which is bolted to the block flange, should be leaking, it may be due to leakage of compressed gas to a health hazard. Leaking pressurized gas containers of this type pose a major problem because they are usually very large. The usual volume is 500 to 900 liters. A leaking gas cylinder must be secured as quickly as possible. In the prior art, he is housed in a Berge tank, which must necessarily have an even larger volume than the male compressed gas container to be received. Such a Bergebehälter has a weight of up to 3 tons and must be brought on demand with heavy transport equipment. It is obvious that all this is very expensive.

Im Stand der Technik gibt es eine Vielfalt von Druckgasbehälten oder Behältern ähnlicher Art.There are a variety of compressed gas containers or containers of a similar nature in the prior art.

Aufgabe der Erfindung ist es, einen Druckgasbehälter der eingangs genannten Art so auszubilden, daß er im Falle einer Undichtigkeit auf einfache Art und Weise gesichert werden kann.The object of the invention is to provide a compressed gas container of the type mentioned in such a way that it can be secured in the event of a leak in a simple manner.

Diese Aufgabe ist erfindungsgemäß durch einen Druckgasbehälter mit den im Anspruch 1 angegebenen Merkmalen gelöst.This object is achieved by a compressed gas container having the features specified in claim 1.

Der Druckgasbehälter nach der Erfindung ist dafür ausgebildet, daß er bei einer Leckage mittels einer massiv ausgebildeten Notfallkappe um seinen Flanschdeckel und oberhalb desselben gasdicht verschließbar ist. Zu diesem Zweck ist bei dem Druckgasbehälter nach der Erfindung der Blockflansch radial außerhalb eines von dem Flanschdeckel abdeckbaren oder abgedeckten Bereiches durch einen massiven Ringflansch verbreitert, der in einer oberen Stirnfläche eine Umfangsnut zur Aufnahme einer Dichtrippe der Notfallkappe aufweist. Die Notfallkappe, die getrennt von dem Druckgasbehälter in Reserve gehalten wird, wird bei Bedarf auf den Druckgasbehälter nach der Erfindung aufgesetzt und mit dessen Ringflansch verschraubt, wobei mittels der Dichtrippe und der sie aufnehmenden Umfangsnut eine gasdichte Verbindung zwischen der Notfallkappe und dem Druckgasbehälter hergestellt wird. Die Notfallkappe wird bei dem Druckgasbehälter nach der Erfindung also nur bei Bedarf eingesetzt, wenn eine Undichtigkeit aufgetreten ist. Der mit der Notfallkappe versehene Druckgasbehälter läßt sich leicht zu dem Befüller transportieren, für den es keine Schwierigkeiten bereitet, den Inhalt des undichten Druckgasbehälters in einen einwandfreien Druckgasbehälter umzufüllen. Ein schwerer Bergebehälter, wie er im Stand der Technik üblich ist und dessen aufwendiger Transport zu dem Ort, an dem sich ein undichter Druckgasbehälter befindet, werden durch die Erfindung überflüssig gemacht. Auch eine Bevorratung der Notfallkappe beim Anwender ist problemlos. Sie benötigt wenig Platz und ist wesentlich billiger als ein Bergebehälter. Die Erfindung ist einfach realisierbar, denn es ist lediglich erforderlich, einen Druckgasbehälter mit einem im Außendurchmesser durch einen Ringflansch verbreiterten Blockflansch zu schaffen und dabei eine Umfangsnut und Verschraubungsmöglichkeiten für die Notfallkappe vorzusehen.The pressurized gas container according to the invention is designed so that it can be closed in a gastight manner in the event of leakage by means of a solid emergency cap around its flange cover and above it. For this purpose, in the compressed gas container according to the invention, the block flange radially outwardly of a coverable or covered by the flange cover area widened by a solid annular flange, which has a circumferential groove for receiving a sealing rib of the emergency cap in an upper end face. The emergency cap, which is kept separate from the compressed gas container in reserve, is placed on demand on the compressed gas container according to the invention and with its Screwed annular flange, wherein by means of the sealing rib and the receiving circumferential groove, a gas-tight connection between the emergency cap and the compressed gas container is made. The emergency cap is used in the compressed gas container according to the invention so only when needed, if a leak has occurred. The provided with the emergency cap compressed gas tank can be easily transported to the filler, for which there is no difficulty to fill the contents of the leaking gas cylinder in a proper compressed gas tank. A heavy Bergebehälter, as is customary in the art and its complex transport to the place where there is a leaking gas cylinder, are made redundant by the invention. Even a storage of the emergency cap at the user is easy. It requires little space and is much cheaper than a Berge container. The invention is easy to implement, because it is only necessary to create a compressed gas tank with a widened in outer diameter by an annular flange block flange and thereby provide a circumferential groove and screw options for the emergency cap.

Zur Erläuterung des einschlägigen Standes der Technik wird zuerst ein herkömmlicher Druckgasbehälter 10 anhand der Fig. 3 und 4 näher betrachtet. Der Druckgasbehälter 10 hat eine Wand, die aus einem zylindrischen Mantel 11, einem oberen elliptischen Boden 12 und einem unteren elliptischen Boden 13 besteht, welche miteinander verschweißt sind. Die Wand hat eine obere Öffnung, in die ein ringförmiger Blockflansch 14 eingeschweißt ist. Der Blockflansch 14 hat einen Kranz von Gewindesacklöchern, in welche jeweils eine nach oben vorstehende Stiftschraube 23 eingeschraubt ist. Ein in Draufsicht kreisförmiger Flanschdeckel 15 weist einen Kranz von Durchgangsbohrungen auf, die mit dem Kranz von Gewindesacklöchern in dem Blockflansch 14 in Deckung sind. Mittels Sechskantmuttern 25 und der Stiftschrauben 23 ist der Flanschdeckel 15 mit dem Blockflansch 14 fest verschraubt. Eine Flachdichtung 31 sorgt für eine gasdichte Abdichtung zwischen dem Blockflansch 14 und dem Flanschdeckel 15. Mit dem Flanschdeckel 15 sind weiter zwei Dreieck-Flansche 16 mittels Stiftschrauben 24 und Sechskantmuttern 26 verschraubt, die jeweils mit einem Entnahmeventil 22 versehen sind. Der Druckgasbehälter 10 hat oben einen Kopfring 18 und unten einen Fußring 19. In dem Kopfring 18 ist eine Schutzkappe 28 angeordnet, die zwei Griffe 29 aufweist. Zwischen jedem Dreieck-Flansch 16 und dem Flanschdeckel 15 ist eine Flachdichtung 32 angeordnet. Jedes Entnahmeventil 22 ist unten mit einem Tauchrohr 21 versehen. Üblicherweise reicht das Tauchrohr 21 des einen Entnahmeventils in den oberen Bereich in dem Druckgasbehälter 10 zur Abgabe des Druckgases in gasförmiger Phase, wohingegen das andere Tauchrohr 21 des anderen Entnahmeventils bis in den Bodenbereich des Druckgasbehälters reicht (nicht dargestellt) zur Abgabe von Druckgas in flüssiger Phase.To explain the relevant prior art, a conventional compressed gas container 10 is first considered in more detail with reference to FIGS. 3 and 4. The pressurized gas container 10 has a wall consisting of a cylindrical shell 11, an upper elliptical bottom 12 and a lower elliptical bottom 13, which are welded together. The wall has an upper opening into which an annular block flange 14 is welded. The block flange 14 has a ring of threaded blind holes, in each of which an upwardly projecting stud 23 is screwed. A circular top view of a flange lid 15 has a collar of through holes which are in register with the ring of threaded blind holes in the block flange 14. By means of hex nuts 25 and the stud bolts 23, the flange 15 is bolted to the block flange 14. A flat seal 31 ensures a gas-tight seal between the block flange 14 and the flange 15. With the flange 15 further two triangular flanges 16 are screwed by means of stud bolts 24 and hex nuts 26, which are each provided with a bleed valve 22. The pressurized gas container 10 has a head ring 18 at the top and a bottom ring 19 at the bottom. A protective cap 28, which has two handles 29, is arranged in the head ring 18. Between each triangle flange 16 and the flange 15, a flat gasket 32 is arranged. Each extraction valve 22 is provided below with a dip tube 21. Usually, the dip tube 21 of the one take-off valve reaches into the upper region in the compressed gas container 10 for discharging the compressed gas in the gaseous phase, whereas the other dip tube 21 of the other take-off valve reaches into the bottom region of the compressed gas container (not shown) for dispensing compressed gas in the liquid phase ,

Im Stand der Technik, wie er in den Fig. 3 und 4 gezeigt ist, ist die Wand des Druckgasbehälters 10, genauer gesagt dessen oberer elliptischer Boden 12 direkt mit dem ringförmigen Blockflansch 14 verschweißt, wie es bei X in Fig. 3 zu erkennen ist. Bis hierher ist der Aufbau des Druckgasbehälters 10 herkömmlich und braucht nicht weiter beschrieben zu werden.In the prior art, as shown in Figs. 3 and 4, the wall of the pressurized gas container 10, more specifically its upper elliptical bottom 12 is welded directly to the annular block flange 14, as can be seen at X in Fig. 3 , So far, the structure of the compressed gas container 10 is conventional and need not be further described.

Im Folgenden wird nun anhand der Fig. 1 und 2 die erfindungsgemäße Abwandlung des Druckgasbehälters 10 beschrieben. Es werden zur Vereinfachung der Darstellung dabei dieselben Bezugszahlen wie in den Fig. 3 und 4 verwendet, sofern es sich um gleiche oder entsprechende Teile handelt.In the following, the modification according to the invention of the compressed gas container 10 will now be described with reference to FIGS. 1 and 2. The same reference numerals as in FIGS. 3 and 4 are used to simplify the illustration, provided that the same or corresponding parts are involved.

Der erfindungsgemäße Druckgasbehälter, der insgesamt mit 10' bezeichnet ist, hat einen Blockflansch 14, der nicht direkt mit dem oberen elliptischen Boden 12 verschweißt ist. Der Blockflansch 14 des Druckgasbehälters 10' wird praktisch in seinem gesamten oberen Bereich bis zu seinem radial äußeren Rand durch den Flanschdeckel 15 abgedeckt. Der Blockflansch 14 des Druckgasbehälters 10' ist radial außerhalb seines von dem Flanschdeckel 15 abgedeckten Bereiches durch einen massiven Ringflansch 40 verbreitert, der außen mit der Wand des Behälters, nämlich mit dem oberen elliptischen Boden 12 bei X' verschweißt ist und innen neben dem abgedeckten Bereich des Blockflansches 14 in einer oberen Stirnfläche 42 eine Umfangsnut 44 zur Aufnahme einer Dichtrippe 46 einer insgesamt mit 50 bezeichneten Notfallkappe aufweist. Der Ringflansch 40 ist in dem dargestellten Ausführungsbeispiel ein gesondertes, mit dem Blockflansch 14 verschweißtes Teil. Statt dessen könnte der Ringflansch 40 mit dem Blockflansch 14 auch einstückig ausgebildet sein. Der Ringflansch 40 ist mit einem Kranz von als Sacklöcher ausgeführten Gewindebohrungen 48 versehen, in die nach oben vorstehende Stiftschrauben 58 eingeschraubt sind.The pressurized gas container according to the invention, which is designated overall by 10 ', has a block flange 14, which is not welded directly to the upper elliptical bottom 12. The block flange 14 of the compressed gas container 10 'is practically covered in its entire upper portion to its radially outer edge by the flange cover 15. The block flange 14 of the pressurized gas container 10 'is widened radially outside its area covered by the flange cover 15 by a solid annular flange 40 which is externally welded to the wall of the container, namely the upper elliptical bottom 12 at X' and inside adjacent to the covered area of the block flange 14 in an upper end face 42 has a circumferential groove 44 for receiving a sealing rib 46 of a total of 50 designated emergency cap. The annular flange 40 is in the illustrated embodiment, a separate, welded to the block flange 14 part. Instead, the annular flange 40 could also be integrally formed with the block flange 14. The annular flange 40 is provided with a ring of threaded holes 48 designed as blind holes, into which upwardly projecting stud bolts 58 are screwed.

Die Notfallkappe 50 weist eine zylindrische Wand 52 auf, die so bemessen ist, dass sie in einem auf den Druckgasbehälter 10' montierten Zustand den Flanschdeckel 15 radial eng umschließt, wie es in Fig. 1 zu erkennen ist. Ein Flanschring ist außen an der zylindrischen Wand 52 der Notfallkappe 50 als ein Befestigungsflansch 54 angeschweißt, der einen Kranz von Durchgangsbohrungen 56 aufweist. Die Durchgangsbohrungen 56 sind mit den Gewindebohrungen 48 des Ringflansches 40 in Deckung, so dass sich die Stiftschrauben 58 nach oben durch die Durchgangsbohrungen 56 hindurch erstrecken. Die Notfallkappe 52 ist durch auf die Stiftschrauben 58 aufgeschraubte Sechskantmuttern 60 auf dem Ringflansch 40 befestigt. Die Dichtrippe 46, die von einer Stirnfläche 62 der zylindrischen Wand 52 vorsteht, ragt in die Umfangsnut 44 hinein, in die eine ringförmige Dichtung 64 eingelegt ist.The emergency cap 50 has a cylindrical wall 52 which is dimensioned so that it radially surrounds the flange cover 15 in a state mounted on the compressed gas container 10 ', as can be seen in FIG. A flange ring is externally welded to the cylindrical wall 52 of the emergency cap 50 as a mounting flange 54 having a collar of through-holes 56. The through holes 56 are in register with the threaded holes 48 of the annular flange 40 so that the stud bolts 58 extend upwardly through the through holes 56. The emergency cap 52 is secured by screwed onto the stud bolts 58 hex nuts 60 on the annular flange 40. The sealing rib 46, which protrudes from an end face 62 of the cylindrical wall 52, protrudes into the circumferential groove 44 into which an annular seal 64 is inserted.

Der Ringflansch 40 weist außen in radialem Abstand von der Umfangsnut 44 einen erhöhten Rand 66 auf, der die zylindrische Wand 52 bei montierter Notfallkappe 50 radial eng umschließt, wie es ebenfalls in Fig. 1 zu erkennen ist. Die Umfangsnut 44 ist mittig zwischen einem Außenumfang des Flanschdeckels 15 und einem Innenumfang des erhöhten Randes 66 des Ringflansches 40 angeordnet, wenn die Notfallkappe 50 wie in Fig. 1 montiert ist. Der Befestigungsflansch 54 ist an der Außenseite der zylindrischen Wand 52 der Notfallkappe 50 so vorgesehen, dass er bei montierter Notfallkappe engen axialen Abstand von einer axial benachbarten Stirnfläche 68 des erhöhten Randes 66 des Ringflansches 40 hat. Im übrigen stimmt der Aufbau des in Fig. 1 gezeigten Druckgasbehälters 10' mit dem Aufbau des Druckgasbehälters 10 nach den Fig. 3 und 4 überein und braucht daher nicht nochmals beschrieben zu werden.The annular flange 40 has, externally at a radial distance from the circumferential groove 44, a raised edge 66 which radially encloses the cylindrical wall 52 when the emergency cap 50 is mounted, as can also be seen in FIG. The circumferential groove 44 is centrally located between an outer periphery of the flange cover 15 and an inner periphery of the raised rim 66 of the annular flange 40 when the emergency cap 50 is mounted as shown in FIG. The mounting flange 54 is provided on the outside of the cylindrical wall 52 of the emergency cap 50 so as to have a close axial distance from an axially adjacent end surface 68 of the raised edge 66 of the annular flange 40 when the emergency cap is mounted. Incidentally, the structure of the compressed gas container 10 'shown in FIG. 1 agrees with the structure of the compressed gas container 10 according to FIGS. 3 and 4 and therefore need not be described again.

In der Darstellung in Fig. 1 ist der Druckgasbehälter 10' ein speziell für den durch den Ringflansch 40 verbreiterten Blockflansch 14 ausgebildeter Druckgasbehälter mit einer entsprechend weiten oberen Öffnung seiner Wand 11, 12, 13. Es wäre auch denkbar, den herkömmlichen Druckgasbehälter 10 so umzurüsten, dass er den Aufbau des Druckgasbehälters 10' nach der Erfindung erhält. Dazu wäre es lediglich erforderlich, in den oberen elliptischen Boden 12 eine Öffnung zu schneiden, die so groß ist wie die Öffnung in dem oberen elliptischen Boden 12 des Druckgasbehälters 10', damit der durch den Ringflansch 40 verbreiterte Blockflansch 14 in den Druckgasbehälter 10 eingeschweißt werden könnte. Die zweckmäßigere Lösung ist aber, den Druckgasbehälter 10' speziell für den vorstehend beschriebenen Zweck herzustellen.In the illustration in Fig. 1, the compressed gas container 10 'is a specially for the widened by the annular flange 40 block flange 14 compressed gas tank with a correspondingly wide upper opening of its wall 11, 12, 13. It would also be conceivable to convert the conventional compressed gas tank 10 so in that it obtains the structure of the pressurized gas container 10 'according to the invention. For this purpose, it would only be necessary to cut into the upper elliptical bottom 12 an opening which is as large as the opening in the upper elliptical bottom 12 of the compressed gas container 10 ', so that the widened by the annular flange 40 block flange 14 are welded into the compressed gas container 10 could. The more expedient solution, however, is to produce the pressurized gas container 10 'specifically for the purpose described above.
