Description
Die Erfindung betrifft einen Spülblock nach dem Oberbegriff des Anspruches 1.The invention relates to a flushing block according to the preamble of claim 1.
Zum Verbinden von Druckgasflaschen mit Abfüll- oder Entnahmesystemen dienen Druckgasflaschenanschlüsse, die beispielsweise mittels einer Überwurfmutter an das Flaschenventil angeschraubt werden. Von dem Druckgasflaschenanschluß führt eine Verbindungsleitung zum Abfüll- oder Entnahmesystem. Wenn die Druckgasflasche leer ist, wird das Flaschenventil geschlossen und der Druckgasflaschenanschluß vom Flaschenventil abgenommen. Dann wird eine gefüllte Druckgasflasche angeschlossen und das Flaschenventil geöffnet. Dann kann weiter Gas in das Abfüll- oder Entnahmesystem gespeist werden.Compressed gas cylinder connections are used to connect compressed gas cylinders to filling or dispensing systems, which are screwed onto the cylinder valve, for example, by means of a union nut. A connecting line leads from the compressed gas cylinder connection to the filling or extraction system. When the compressed gas cylinder is empty, the cylinder valve is closed and the cylinder connection is removed from the cylinder valve. Then a filled compressed gas cylinder is connected and the cylinder valve is opened. Then gas can continue be fed into the filling or dispensing system.
Dieser einfache Austausch der Druckgasflaschen ist bei explosiblen, selbstentzündlichen und insbesondere bei toxischen Gasen, deren MAK-Werte, je nach Medium, niedriger als 0,1 ppm liegen, nicht möglich. In den Totvolumina, insbesondere zwischen Flaschenventil und Druckgasflaschenanschluß sowie im Druckgasflaschenanschluß und der anschließenden Verbindungsleitung selbst, befindet sich nämlich soviel Gas, daß dieses nicht gefahrlos an die Umgebung abgegeben werden kann. Immer mehr wird daher deren Gestaltung auch beeinflußt, von der Notwendigkeit durch intensive Spülung mit einem Spülgas die Gefahren zu vermeiden. Außerdem ist es in vielen Fällen erforderlich, eingeströmte Athmosphäre (Luftfeuchtigkeit) durch Spülen zu entfernen, um bei korrosiven Gasen Salzbildung zu vermeiden. So ist es bekannt, das Flaschenventil mit einer Spül-gasleitung zu versehen. Die Spülgasleitung ist dabei mit einem Spülventil ausgestattet (DE-C-36 22 527).This simple exchange of compressed gas cylinders is not possible with explosive, self-igniting and especially with toxic gases, whose MAK values, depending on the medium, are lower than 0.1 ppm. There is so much gas in the dead volume, in particular between the cylinder valve and the compressed gas cylinder connection and in the compressed gas cylinder connection and the connecting pipe itself, that it cannot be safely released into the environment. Therefore, their design is increasingly influenced by the need to avoid the dangers by intensive purging with a purge gas. In addition, in many cases it is necessary to purge the atmosphere (air humidity) to prevent salt formation in the case of corrosive gases. So it is known to provide the bottle valve with a purge gas line. The purge gas line is equipped with a purge valve (DE-C-36 22 527).
Nach dem DE-U-86 22 871 wird vorgeschlagen, den Druckgasflaschenanschluß mit einer Spülgasleitung zu versehen. Die Spülgasleitung ist über einen Spülanschluß an eine Spülgasversorgung angeschlossen.According to DE-U-86 22 871 it is proposed to provide the compressed gas cylinder connection with a purge gas line. The purge gas line is connected to a purge gas supply via a purge connection.
Über diese Spülgasanschlüsse muß man das Spülgas aber solange in die Spülgasleitung ein- und über die Entnahmebohrung des Flaschenventiles in die sich anschließenden Verbindungsleitungen und Armaturen weiterströmen lassen, bis das gesamte Prozeßgas verdrängt ist.These purge gas connections must be used to allow the purge gas to flow into the purge gas line and continue to flow into the connecting lines and fittings via the removal bore of the cylinder valve until the entire process gas is displaced.
Der Erfindung liegt daher die Aufgabe zugrunde, einen Spülblock zu schaffen, welcher es ermöglicht, die Prozeßgase ausschließlich aus den Totvolumina einer Armatur, insbesondere eines Flaschenventiles, zu verdrängen.The invention is therefore based on the object of providing a flushing block which makes it possible to displace the process gases exclusively from the dead volumes of a fitting, in particular a cylinder valve.
Ausgehend von dem im Oberbegriff des Anspruches 1 berücksichtigten Stand der Technik ist diese Aufgabe erfindungsgemäß gelöst mit den im kennzeichnenden Teil des Anspruches 1 angegebenen Merkmalen. Vorteilhafte Weiterbildungen der Erfindung sind in den Unteransprüchen angegeben.Starting from the prior art taken into account in the preamble of claim 1, this object is achieved according to the invention with the features specified in the characterizing part of claim 1. Advantageous developments of the invention are specified in the subclaims.
Die mit der Erfindung erzielten Vorteile bestehen darin, daß statt einer Vielzahl von Armaturen und Verbindungsleitungen nur das Flaschenventil in Form einer offenen Ringspülung gespült werden kann. Beim Spülen mit einem Inert- oder Spülgas wird über ein Absperrventil die Entnahmeleitung abgesperrt, so daß aus den angeschlossenen Verbindungsleitungen und Gasentnahmearmaturen kein Prozeßgas aus- und keine Luft bzw. Feuchtigkeit eintreten kann. Vorteilhaft ist hierbei, daß bei dem Spülvorgang kein mit Feuchtigkeit und Prozeßgas angereichertes Spülgas durch die Gasentnahmearmaturen, z. B. Druckregler oder Feindosierventil, strömt.The advantages achieved by the invention are that instead of a large number of fittings and connecting lines, only the bottle valve can be flushed in the form of an open ring flush. When purging with an inert or purge gas, the sampling line is shut off via a shut-off valve, so that no process gas can escape from the connected connecting lines and gas sampling fittings and no air or moisture can enter. It is advantageous here that during the flushing process no flushing gas enriched with moisture and process gas through the gas sampling fittings, e.g. B. pressure regulator or metering valve flows.
Weitere Vorteile ergeben sich dadurch, daß über den Spülblock die Spülgasaus- und -eingänge sowie die Entnahmebohrung geöffnet oder geschlossen werden können, so daß bei Bedarf, z. B. wenn die leere Druckgasflasche das gleiche Prozeßgas enthält, wie die neu anzuschließende Druckgasflasche, nur das Flaschenventil - andererseits jedoch auch das gesamte Abfülloder Entnahmesystem gespült werden können.Further advantages result from the fact that the flushing gas outlets and inlets as well as the removal bore can be opened or closed via the flushing block, so that if necessary, for. B. if the empty gas cylinder contains the same process gas as the new one Pressurized gas cylinder to be connected, only the cylinder valve - on the other hand, however, the entire filling or dispensing system can also be flushed.
Dadurch, daß die Absperrventile und der Spülgaseinund ausgang in einem Gehäuse vereinigt sind, werden die Totvolumen verringert und die Bedienung erleichtert. Verunreinigungskomponenten wie Partikel und Feuchtigkeit werden minimiert, der Spülgasverbrauch verringert und die Spülzeit beim Druckgasflaschenwechsel reduziert sich.Because the shut-off valves and the purge gas inlet and outlet are combined in one housing, the dead volume is reduced and operation is made easier. Contamination components such as particles and moisture are minimized, the purge gas consumption is reduced and the purge time when changing the gas cylinder is reduced.
Ein Ausführungsbeispiel ist in der Zeichnung dargestellt und wird im folgenden näher beschrieben.An embodiment is shown in the drawing and will be described in more detail below.

Der in den Fig. 1 und 2 dargestellte Spülblock 10 besteht aus einem Anschlußteil 11, auf dem eine Überwurfmutter 12 angeordnet ist. Mittels der Überwurfmutter 12, die an einen radial von dem Anschlußteil abstehenden Flansch 13 anlegbar ist, wird der Spülblock 10 an das Flaschenventil 14 angeschraubt. An das Anschlußteil 11 ist das Gehäuse 15 des Spülblockes 10 z. B. angeschweißt.The
Anschlußteil 11 und Gehäuse 15 weisen eine Entnahmebohrung 16 auf, die mit dem Ausgang 17 des Flaschenventiles 14 in Verbindung steht. Erfindungsgemäß ist die Entnahmebohrung 16 über ein in dem Gehäuse 15 angeordnetes Absperrventil 19 mit einem Prozeßgasausgang 20 verbunden.
Das Gehäuse 15 weist ferner einen Spülgaseingang 21 auf, der über ein in dem Gehäuse 15 angeordnetes Absperrventil 22 mit dem Ausgang 17 des Flaschenventiles 14 verbunden ist. Die Verbindung erfolgt durch ein in der Entnahmebohrung 16 verlaufendes und in dem Gehäuse 15 angeordnetes Rohr 23 und eine Bohrung 24.The
Über eine von der Entnahmebohrung 16 abzweigende Bohrung 25 und ein in dem Gehäuse 15 angeordnetes Absperrventil 26 ist der Ausgang 17 des Flaschenventiles mit einem Spülgasausgang 27 verbunden.The
In den Figuren sind die Absperrventile 19, 22 und 26 als handbetätigte Ventile dargestellt. Es ist selbstverständlich und bedarf keiner ausführlichen Beschreibung, daß diese Absperrventile auch automatisch, beispielsweise pneumatisch oder hydraulich betätigt werden können.In the figures, the shut-off
Mit dem erfindungsgemäßen Spülblock lassen sich gefahrlos Druckgasflaschen mit gefährlichem Inhalt austauschen. Hierzu schließt man zunächst das Flaschenventil 14 und das Absperrventil 19 und läßt dann durch den Spülgaseingang 21 ein Spül- oder Inertgas einströmen. Dieses gelangt bei geöffneten Absperrventilen 22 und 26 durch die Bohrung 24 und das Rohr 23 in den Anschluß 17 des Flaschenventiles 14. Das in den dortigen Totvolumen befindliche Prozeßgas wird mit dem Spülgas vermischt und strömt durch die Bohrung 25 zu dem Spülgasausgang 27. Man läßt das Spülgas durch den Spülgaseingang 21 solange einströmen, bis das gesamte Prozeßgas in dem Flaschenventil und dem Spülblock verdrängt ist. Danach unterbricht man die Spülgaszufuhr durch Schließen des Absperrventiles 22. Die Druckgasflasche kann hiernach gefahrlos gegen eine frisch gefüllte getauscht werden.With the flushing block according to the invention, compressed gas cylinders with dangerous contents can be exchanged safely. For this purpose, first the
Für einen kompakten Aufbau und eine einfache Bedienung des Spülblockes ist es von Vorteil, daß das Absperrventil 22 in der gleichen horizontalen Ebene über Eck zu dem Absperrventil 26 und auf der gleichen Mittelachse des Rohres 23 angeordnet ist. Das Absperrventil 19 ist im Kreuzungsbereich der Mittelachsen der Absperrventile 22, 26 senkrecht zu diesen im Gehäuse 15 angeordnet. Dabei treten der Spülgaseingang 21 und der Spülgasausgang 27 an einer gemeinsamen Seite 28 aus dem Gehäuse 15 aus.For a compact structure and simple operation of the flushing block, it is advantageous that the shut-off
Es ist selbstverständlich auch vorteilhaft möglich, alle Absperrventile 19, 22, 26 in der gleichen horizontalen Ebene über Eck zueinander anzuordnen. Dabei ist vorteilhaft das Absperrventil 22 dem Anschluß 12, 13, 17 des Flaschenventiles gegenüberliegend angeordnet, während die Absperrventile 19,26 jeweils links bzw. rechts von ihm angeordnet sind. Durch diese Maßnahme strömt das Brauchgas senkrecht zu den Absperrventilen 19, 22, 26 und gebenüberliegend von dem Spülgasaus bzw. -eingang 21 bzw. 27 aus dem Spülblock zu einer Armatur, beispielsweise ein Druckregler. Dabei sind die dem Druckregler zugeordneten Manometer vorteilhaft in der richtigen Ableseposition angeordnet.It is of course also advantageously possible to arrange all the shut-off
Für eine schnelle und wirksame Spülung des Flaschenventiles ist es von großem Vorteil, daß der Spülblock 10 über einen Spülgasausgang 27 verfügt, so daß die Spülung in Form einer Ringspülung vorgenommen werden kann.For a quick and effective flushing of the bottle valve, it is of great advantage that the
Unter Betriebsbedingungen werden, wie in den Fig. 1 und 2 dargestellt, die Absperrventile 22 und 26 geschlossen. Prozeßgas strömt bei geöffnetem Flaschenventil über die Entnahmebohrung 16 und das geöffnete Absperrventil 19 zu dem Prozeßgasausgang 20.Under operating conditions, as shown in FIGS. 1 and 2, the shut-off
In Fig.3 ist eine Vorrichtung für die Prozeßgase mit einem Spülblock 10 dargestellt, dessen Spülgaseingang 21 über einen Druckminderer 29 und ein Flaschenventil 30 mit einer Spülgasflasche 31 verbunden ist. Der Anschluß 11, 12, 13 des Spülblockes 10 ist an das Flaschenventil 14 der Prozeßgasflasche 18 angeschlossen. Mit dem Prozeßgasausgang 20, der in Fig.3, beispielsweise auf der oberen Seite des Spülblockes austritt, ist der Spülblock mit einem Gasentnahme- oder Abfüllsystem 32 verbunden. Erfindungsgemäß wird nunmehr weiter vorgeschlagen, den Spülgasausgang 27 über ein Rückschlagventil 33 mit einer leeren Entsorgungsgasflasche 34 bzw. einem Entsorgungsgasbehälter zu verbinden, in die das Prozeß-Spülgasgemisch bzw. das Atmosphären-Spülgasgemisch beim Spülvorgang strömt. Dabei kann in der zwischen Spülblock 10 und Entsorgungsgasflasche 34 angeordneten Verbindungsleitung 35 ein Druckübersetzer 36 angeordnet werden, mittels dem bei abnehmenden Spülgas- und ansteigendem Entsorgungsflaschendruck der Spülgasdruck in der Hinterdruckleitung erhöht wird. Durch diese Maßnahme kann die Entsorgungsgasflasche auch bei abnehmendem Spülgasdruck gefüllt werden. Ein weiteres Verfahren besteht in der Verflüssigung des Prozeß-Spülgasgemisches bzw. Atmosphären-Spülgasgemisches vor dessen Entsorgung mittels eines Entsorgungsgasbehälters. Neben der Verflüssigung kann das Prozeß-Spülgasgemisch bzw. Atmosphären-Spülgasgemisch auch über ein chemisches Reaktionsverfahren verfestigt und ebenfalls mittels eines Entsorgungsgasbehälters entsorgt werden. Bei allen Entsorgungsverfahren können dabei toxische Bestandteile mittels entsprechender Chemikalien neutralisiert werden. Nach dem Befüllen der Entsorgungsgasflasche 34 wird deren Flaschenventil 38 geschlossen, die Verbindung zu der Hinterdruckleitung 37 gelöst und die volle Entsorgungsgasflasche gegen eine leere Entsorgungsgasflasche ausgetauscht.FIG. 3 shows a device for the process gases with a
