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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
