Definitions
- the invention relates to a filling station for gas cylinders, in particular LPG cylinders.
- the invention further relates to a method for refilling gas cylinders.
- a filling station for gas cylinders is from the publication DE 32 14 629 A1 known.
- a gas cylinder is usually a metal, regular steel, existing pressure vessel for the transport and storage of pressurized gases.
- a gas bottle can also consist of aluminum or composite materials. Such a bottle may have a volume of more than 100 liters. The nominal pressure can be several hundred bar.
- LPG cylinders contain gases such as LPG in liquefied form. Common gases are ethane, propane, butane and mixtures thereof. These gases can be liquefied at room temperature by comparatively low pressure.
- Liquefied gas cylinders are closed with a fitting to which, usually in conjunction with a pressure reducer, a suitable hose line for the controlled removal of their contents can be screwed. Furthermore, there is a safety valve for LPG cylinders in the sampling fitting, which limits the permissible overpressure in the bottle to, for example, about 30 bar in order to prevent bursting.
- a fitting of such a liquid gas cylinder has a lateral connecting piece, which is used on the one hand for filling and on the other hand for removal.
- lateral connection pipes pipes are manually screwed both in the case of removal and in the case of refilling.
- LPG cylinders are used to operate gas stoves, gas stoves, gas grills, gas stoves or gas radiators. If the contents of a LPG cylinder are used up, LPG cylinders are returned by the consumer to the point of sale of LPG cylinders for refilling. After such a return of a liquefied gas cylinder it is transported from the point of sale to a central bottling plant or filling station.
- the claimed filling station allows an automated refilling of a gas cylinder by an end user.
- This includes an inserter that allows an end user to place an emptied gas bottle in the filling station.
- the filling station comprises a closing device for closing the filling station following the insertion of the gas cylinder in such a way that removal of the gas cylinder following closure is not possible. The end user can not remove the gas bottle in the closed state.
- the filling station comprises a filling device for an automated filling of an emptied gas cylinder inserted into the filling station following the closing. A filling can therefore only take place when the filling station is closed and the gas cylinder can not therefore be removed.
- a gas testing device for an automated gas-tightness test following a refilling of a gas cylinder is present.
- the filling station is thus designed so that an end user can fill a gas bottle used by him again with gas for further use, without having to deliver a gas cylinder at a responsible delivery point such as a point of sale. It eliminates a usual onward transport from a delivery point to a central bottling plant. This allows the transport costs together with associated personnel expenses. A consumer can receive a refilled bottle regardless of charge opening times.
- a gas tightness test also takes place before refilling. If this GastdGermans phenomenon that an inserted, largely emptied gas cylinder is already leaking, so this is not refilled. Preferably, instead of the remaining contents is emptied and then released completely empty bottle to the consumer.
- a transport effort can be further improved thereby reduced, by claiming filling stations are placed in places where gas cylinders are usually used or to which liquefied gas is usually transported. Therefore, for example, campsites and / or gas stations are preferably equipped with demanding bottling stations.
- An achieved further reduction of transport costs contributes further u. a. to protect the environment.
- the filling station has an identification device with which a gas cylinder can be identified. It can thus be determined whether a gas cylinder is suitable for automatic filling.
- the filling can be controlled as a function of the result of an identification. It is therefore only filled if it has previously been determined by the identification device that the gas cylinder used is suitable.
- the identification can also determine which volume and which size the gas cylinder used has. As a result, the refilling can be controlled and accelerated. Deviations from the expected result, for example with regard to the filling quantity, can be used to identify faults. For example, it is determined by the identification device that a maximum of 5 kg of gas may be introduced into a gas cylinder used.
- the filling station determines that there is still a residual gas quantity of 1 kg in the gas cylinder.
- the filling station can then be set up in such a way that it is automatically determined, even before the beginning of the filling process, that no more than 4 kg is filled into the gas cylinder.
- the filling station is set up so that it is always locked. When closed, no gas cylinder can be inserted into the filling station and no gas cylinder can be removed from the filling station. If a gas cylinder is to be used, it must first be identified as suitable by the identification device. Only if this test proves that a gas cylinder is suitable, the filling station opens and allows insertion of the gas cylinder. Inserting the gas cylinder in the filling station is therefore only possible following a successful identification test.
- an identification of the gas cylinder used by the identification device takes place, preferably following a closing of the filling station. There is thus a final check whether in fact a suitable gas cylinder has been used to avoid malfunctions so further improved.
- the gas cylinder in the inserted state, is in a completely closed space when the filling station is closed, so as to shield an inserted gas cylinder in the maximum possible way to the outside when it is refilled.
- the safety is further improved.
- the filling station comprises a scale with which the weight of an inserted gas cylinder is determined before refilling and / or after refilling.
- the filling station can determine how much gas can be filled into the bottle.
- the filling station can check that the gas cylinder has been completely and properly filled. Deviations from the expected result signal a fault and thus contribute to improved safety.
- determining the weight of the gas cylinder both before refilling and after refilling it can be determined how much gas has been poured into the bottle. This can be used to control the filling and / or bill against the consumer.
- a gas flow meter in a supply line of the filling station can be used to determine how much gas has been filled into a gas cylinder used, for example, to settle accounts with the consumer or to detect faults.
- the filling station comprises an emptying device with which an inserted gas cylinder can be emptied.
- the emptying device By the emptying device, the contents of a gas cylinder used in particular emptied when a fault has been detected. If, for example, a gas-tightness test shows that the filled gas cylinder is not tight, the gas bottle is emptied by the emptying device. Risks are reduced so further improved.

Description
Die Erfindung betrifft eine Abfüllstation für Gasflaschen, insbesondere Flüssiggasflaschen. Die Erfindung betrifft ferner ein Verfahren für ein Wiederbefüllen von Gasflaschen.The invention relates to a filling station for gas cylinders, in particular LPG cylinders. The invention further relates to a method for refilling gas cylinders.
Eine Abfüllstation für Gasflaschen ist aus der Druckschrift
Eine Gasflasche ist ein in der Regel aus Metall, regelmäßig aus Stahl, bestehender Druckbehälter für den Transport und die Lagerung von unter Druck stehenden Gasen. Eine Gasflasche kann aber auch aus Aluminium oder Kompositwerkstoffen bestehen. Eine solche Flasche kann ein Volumen von mehr als 100 Litern aufweisen. Der Nenndruck kann mehrere Hundert bar betragen.A gas cylinder is usually a metal, regular steel, existing pressure vessel for the transport and storage of pressurized gases. A gas bottle can also consist of aluminum or composite materials. Such a bottle may have a volume of more than 100 liters. The nominal pressure can be several hundred bar.
In Flüssiggasflaschen befinden sich Gase wie zum Beispiel LPG in verflüssigter Form. Übliche Gase sind Ethan, Propan, Butan sowie Gemische davon. Diese Gase können bei Raumtemperatur durch vergleichsweise geringen Druck verflüssigt werden.LPG cylinders contain gases such as LPG in liquefied form. Common gases are ethane, propane, butane and mixtures thereof. These gases can be liquefied at room temperature by comparatively low pressure.
Flüssiggasflaschen werden mit einer Armatur verschlossen, an der sich, meist in Verbindung mit einem Druckminderer, eine passende Schlauchleitung zur kontrollierten Entnahme ihres Inhaltes anschrauben lässt. Des Weiteren befindet sich bei Flüssiggasflaschen in der Entnahmearmatur ein Sicherheitsventil, welches den zulässigen Überdruck in der Flasche auf zum Beispiel ca. 30 bar begrenzt, um ein Bersten zu verhindern.Liquefied gas cylinders are closed with a fitting to which, usually in conjunction with a pressure reducer, a suitable hose line for the controlled removal of their contents can be screwed. Furthermore, there is a safety valve for LPG cylinders in the sampling fitting, which limits the permissible overpressure in the bottle to, for example, about 30 bar in order to prevent bursting.
Typischerweise weist eine Armatur einer solchen Flüssiggasflasche einen seitlichen Anschlussstutzen auf, der einerseits zum Auffüllen und andererseits zur Entnahme verwendet wird. An diesen seitlichen Anschlussstutzen werden Leitungen sowohl im Fall der Entnahme als auch im Fall einer Wiederbefüllung manuell aufgeschraubt.Typically, a fitting of such a liquid gas cylinder has a lateral connecting piece, which is used on the one hand for filling and on the other hand for removal. On these lateral connection pipes, pipes are manually screwed both in the case of removal and in the case of refilling.
Flüssiggasflaschen werden für den Betrieb von Gasherden, Gaskochern, Gasgrills, Gasheizöfen oder Gasheizstrahlern eingesetzt. Ist der Inhalt einer Flüssiggasflasche verbraucht, so werden Flüssiggasflaschen vom Verbraucher an die Verkaufsstelle von Flüssiggasflaschen zwecks erneuter Auffüllung zurückgegeben. Nach einer solchen Rückgabe einer Flüssiggasflasche wird diese von der Verkaufsstelle zu einer zentralen Abfüllanlage bzw. Abfüllstation transportiert.LPG cylinders are used to operate gas stoves, gas stoves, gas grills, gas stoves or gas radiators. If the contents of a LPG cylinder are used up, LPG cylinders are returned by the consumer to the point of sale of LPG cylinders for refilling. After such a return of a liquefied gas cylinder it is transported from the point of sale to a central bottling plant or filling station.
Um eine Wiederbefüllung zu erleichtern, ist aus der Druckschrift
Es ist Aufgabe der Erfindung, den technischen Aufwand für ein Wiederbefüllen von Gasflaschen zu verringern.It is an object of the invention to reduce the technical complexity of refilling gas cylinders.
Die Aufgabe der Erfindung wird durch eine Abfüllstation mit den Merkmalen des Hauptanspruchs sowie durch ein Verfahren mit den Merkmalen des Nebenanspruchs gelöst. Vorteilhafte Ausgestaltungen ergeben sich aus den abhängigen Ansprüchen.The object of the invention is achieved by a filling station with the features of the main claim and by a method having the features of the independent claim. Advantageous embodiments emerge from the dependent claims.
Die anspruchsgemäße Abfüllstation ermöglicht ein automatisiertes Wiederbefüllen einer Gasflasche durch einen Endverbraucher. Diese umfasst eine Einsetzeinrichtung, die es einem Endverbraucher ermöglicht, eine entleerte Gasflasche in die Abfüllstation einzusetzen. Die Abfüllstation umfasst eine Schließeinrichtung für ein Verschließen der Abfüllstation im Anschluss an das Einsetzen der Gasflasche derart, dass eine Entnahme der Gasflasche im Anschluss an das Verschließen nicht möglich ist. Der Endverbraucher kann im verschlossenen Zustand die Gasflasche nicht entnehmen. Weiter umfasst die Abfüllstation eine Befülleinrichtung für ein automatisiertes Befüllen einer in die Abfüllstation eingesetzten entleerten Gasflasche im Anschluss an das Verschließen. Ein Befüllen kann daher nur dann stattfinden, wenn die Abfüllstation verschlossen ist und die Gasflasche folglich nicht entnommen werden kann. Eine Gasprüfeinrichtung für eine automatisierte Gasdichtigkeitsprüfung im Anschluss an eine Wiederbefüllung einer eingesetzten Gasflasche ist vorhanden. Mit dieser wird die Dichtigkeit einer wieder gefüllten Gasflasche überprüft. Es gibt eine Freigabeeinrichtung, die eine zuvor befüllte bzw. gefüllte Gasflasche erst im Anschluss an eine erfolgreiche Gasdichtigkeitsprüfung freigibt und so eine Entnahme einer wieder gefüllten Gasflasche ermöglicht. Eine Entnahme einer mit Gas bzw. Flüssiggas gefüllten Gasflasche ist also nur dann möglich, wenn die Gasdichtigkeitsprüfung ergeben hat, dass kein Gas aus der gefüllten Flasche austritt.The claimed filling station allows an automated refilling of a gas cylinder by an end user. This includes an inserter that allows an end user to place an emptied gas bottle in the filling station. The filling station comprises a closing device for closing the filling station following the insertion of the gas cylinder in such a way that removal of the gas cylinder following closure is not possible. The end user can not remove the gas bottle in the closed state. Furthermore, the filling station comprises a filling device for an automated filling of an emptied gas cylinder inserted into the filling station following the closing. A filling can therefore only take place when the filling station is closed and the gas cylinder can not therefore be removed. A gas testing device for an automated gas-tightness test following a refilling of a gas cylinder is present. With this, the tightness of a refilled gas cylinder is checked. There is a release device that releases a previously filled or filled gas cylinder only after a successful gas leak test and thus allows removal of a refilled gas cylinder. A removal of a filled with gas or LPG gas cylinder is therefore only possible if the gas-tightness test has shown that no gas escapes from the filled bottle.
Die Abfüllstation ist damit so ausgestaltet, dass ein Endverbraucher eine von ihm genutzte Gasflasche wieder mit Gas für eine Weiternutzung füllen kann, ohne dafür eine Gasflasche an einer zuständigen Abgabestelle wie zum Beispiel einer Verkaufsstelle abgeben zu müssen. Es entfällt damit ein üblicher Weitertransport von einer Abgabestelle zu einer zentralen Abfüllanlage. Hierdurch lässt sich der Transportaufwand nebst zugehörigem Personalaufwand verringern. Ein Verbraucher kann eine wieder gefüllte Flasche unabhängig von Ladungsöffnungszeiten zurück erhalten.The filling station is thus designed so that an end user can fill a gas bottle used by him again with gas for further use, without having to deliver a gas cylinder at a responsible delivery point such as a point of sale. It eliminates a usual onward transport from a delivery point to a central bottling plant. This allows the transport costs together with associated personnel expenses. A consumer can receive a refilled bottle regardless of charge opening times.
Da ein Verbraucher eine gefüllte Flasche nur zurückerhält, wenn diese auch tatsächlich gasdicht ist, besteht nicht das Risiko, dass ein Defekt bei einer Gasflasche unbemerkt bleibt und somit erhöhte Sicherheitsrisiken für einen Endverbraucher bestehen.Since a consumer only recovers a filled bottle when it is actually gas-tight, there is no risk that a gas bottle defect will go unnoticed and thus increase the safety risks for an end consumer.
In einer Ausgestaltung findet eine Gasdichtigkeitsprüfung auch vor einem Wiederbefüllen statt. Ergibt diese Gastdichtigkeitsprüfung, dass eine eingesetzte, weitgehend entleerte Gasflasche bereits undicht ist, so wird diese nicht wieder befüllt. Vorzugsweise wird stattdessen der Restinhalt entleert und die dann vollständig entleerte Flasche an den Verbraucher freigegeben.In one embodiment, a gas tightness test also takes place before refilling. If this Gastdichtigkeitsprüfung that an inserted, largely emptied gas cylinder is already leaking, so this is not refilled. Preferably, instead of the remaining contents is emptied and then released completely empty bottle to the consumer.
Ein Transportaufwand kann weiter verbessert dadurch reduziert werden, indem anspruchsgemäße Abfülllstationen an Orten aufgestellt werden, an denen üblicherweise Gasflaschen verwendet werden oder zu denen Flüssiggas üblicherweise transportiert wird. Bevorzugt werden daher zum Beispiel Campingplätze und/ oder Tankstellen mit anspruchsgemäßen Abfülllstationen ausgerüstet. Eine so erreichte weitere Reduzierung des Transportaufwands trägt weiter verbessert u. a. zur Schonung der Umwelt bei.A transport effort can be further improved thereby reduced, by claiming filling stations are placed in places where gas cylinders are usually used or to which liquefied gas is usually transported. Therefore, for example, campsites and / or gas stations are preferably equipped with demanding bottling stations. An achieved further reduction of transport costs contributes further u. a. to protect the environment.
In einer Ausgestaltung weist die Abfüllstation eine Identifizierungseinrichtung auf, mit der eine Gasflasche identifiziert werden kann. Es kann so festgestellt werden, ob eine Gasflasche für eine automatische Abfüllung geeignet ist. Durch eine entsprechende Steuerungseinrichtung kann das Abfüllen in Abhängigkeit vom Ergebnis einer Identifizierung gesteuert werden. Es wird also nur abgefüllt, wenn zuvor durch die Identifizierungseinrichtung festgestellt worden ist, dass die eingesetzte Gasflasche geeignet ist. Durch die Identifizierung kann ferner festgestellt werden, welches Volumen und welche Größe die eingesetzte Gasflasche aufweist. Hierdurch kann das Wiederbefüllen gesteuert und beschleunigt werden. Abweichungen vom erwarteten Ergebnis beispielsweise in Bezug auf die Füllmenge können dazu genutzt werden, um Störungen zu identifizieren. Beispielsweise wird durch die Identifizierungseinrichtung festgestellt, dass in eine eingesetzte Gasflasche maximal 5 kg Gas eingefüllt werden dürfen. Durch Messung des Gewichtes der eingesetzten und noch nicht wieder befüllten Gasflasche stellt die Abfüllstation fest, dass sich noch eine Restgasmenge von 1 kg in der Gasflasche befindet. Die Abfüllstation kann dann so eingerichtet sein, dass dann automatisiert bereits vor Beginn des Füllvorgangs festgelegt wird, dass nicht mehr als 4 kg in die Gasflasche eingefüllt wird.In one embodiment, the filling station has an identification device with which a gas cylinder can be identified. It can thus be determined whether a gas cylinder is suitable for automatic filling. By means of a corresponding control device, the filling can be controlled as a function of the result of an identification. It is therefore only filled if it has previously been determined by the identification device that the gas cylinder used is suitable. The identification can also determine which volume and which size the gas cylinder used has. As a result, the refilling can be controlled and accelerated. Deviations from the expected result, for example with regard to the filling quantity, can be used to identify faults. For example, it is determined by the identification device that a maximum of 5 kg of gas may be introduced into a gas cylinder used. By measuring the weight of the gas cylinder used and not yet refilled, the filling station determines that there is still a residual gas quantity of 1 kg in the gas cylinder. The filling station can then be set up in such a way that it is automatically determined, even before the beginning of the filling process, that no more than 4 kg is filled into the gas cylinder.
Um Probleme aufgrund von Missbrauch und Vandalismus zu verringern, ist die Abfüllstation so eingerichtet, dass diese grundsätzlich verschlossen ist. Im verschlossenen Zustand kann keine Gasflasche in die Abfüllstation eingesetzt werden und auch keine Gasflasche aus der Abfüllstation herausgenommen werden. Soll eine Gasflasche eingesetzt werden, so muss diese durch die Identifizierungseinrichtung zunächst als geeignet identifiziert werden. Nur wenn diese Prüfung ergibt, dass eine Gasflasche geeignet ist, so öffnet sich die Abfüllstation und ermöglicht ein Einsetzen der Gasflasche. Ein Einsetzen der Gasflasche in die Abfüllstation ist also nur im Anschluss an eine erfolgreiche Identifizierungsprüfung möglich.To reduce problems due to abuse and vandalism, the filling station is set up so that it is always locked. When closed, no gas cylinder can be inserted into the filling station and no gas cylinder can be removed from the filling station. If a gas cylinder is to be used, it must first be identified as suitable by the identification device. Only if this test proves that a gas cylinder is suitable, the filling station opens and allows insertion of the gas cylinder. Inserting the gas cylinder in the filling station is therefore only possible following a successful identification test.
In einer Ausgestaltung findet alternativ oder ergänzend eine Identifizierung der eingesetzten Gasflasche durch die Identifizierungseinrichtung statt und zwar vorzugsweise im Anschluss an ein Verschließen der Abfüllstation. Es findet so eine letzte Kontrolle statt, ob tatsächlich eine geeignete Gasflasche eingesetzt worden ist, um Fehlfunktionen so weiter verbessert zu vermeiden.In one embodiment, alternatively or additionally, an identification of the gas cylinder used by the identification device takes place, preferably following a closing of the filling station. There is thus a final check whether in fact a suitable gas cylinder has been used to avoid malfunctions so further improved.
Vorzugsweise befindet sich im eingesetzten Zustand die Gasflasche in einem vollständig geschlossenen Raum, wenn die Abfüllstation verschlossen ist, um so eine eingesetzte Gasflasche in maximal möglicher Weise nach außen abzuschirmen, wenn diese wieder gefüllt wird. Die Sicherheit wird so weiter verbessert.Preferably, in the inserted state, the gas cylinder is in a completely closed space when the filling station is closed, so as to shield an inserted gas cylinder in the maximum possible way to the outside when it is refilled. The safety is further improved.
In einer Ausgestaltung umfasst die Abfüllstation eine Waage, mit der das Gewicht einer eingesetzten Gasflasche vor dem Wiederbefüllen und/oder nach dem Wiederbefüllen ermittelt wird. Indem das Gewicht der Gasflasche vor dem Wiederbefüllen ermittelt wird, kann die Abfüllstation feststellen, wie viel Gas in die Flasche gefüllt werden kann. Indem das Gewicht der Gasflasche nach dem Wiederbefüllen ermittelt wird, kann die Abfüllstation kontrollieren, ob die Gasflasche vollständig und ordnungsgemäß gefüllt worden ist. Abweichungen vom erwarteten Ergebnis signalisieren eine Störung und tragen so verbessert zur Sicherheit bei. Indem das Gewicht der Gasflasche sowohl vor dem Wiederbefüllen als auch nach dem Wiederbefüllen ermittelt wird, kann ermittelt werden, wie viel Gas in die Flasche eingefüllt worden ist. Dies kann dazu genutzt werden, um das Befüllen zu steuern und/ oder gegenüber dem Verbraucher abzurechnen. Alternativ oder ergänzend kann ein Gasdurchflussmesser in einer Zuführleitung der Abfüllstation dazu genutzt werden, um zu ermitteln, wie viel Gas in eine eingesetzte Gasflasche eingefüllt worden ist, um beispielsweise gegenüber dem Verbraucher abzurechnen oder aber Störungen zu ermitteln.In one embodiment, the filling station comprises a scale with which the weight of an inserted gas cylinder is determined before refilling and / or after refilling. By determining the weight of the gas cylinder before refilling, the filling station can determine how much gas can be filled into the bottle. By determining the weight of the gas cylinder after refilling, the filling station can check that the gas cylinder has been completely and properly filled. Deviations from the expected result signal a fault and thus contribute to improved safety. By determining the weight of the gas cylinder both before refilling and after refilling, it can be determined how much gas has been poured into the bottle. This can be used to control the filling and / or bill against the consumer. Alternatively or additionally, a gas flow meter in a supply line of the filling station can be used to determine how much gas has been filled into a gas cylinder used, for example, to settle accounts with the consumer or to detect faults.
In einer Ausgestaltung der Erfindung umfasst die Abfüllstation eine Entleerungseinrichtung, mit der eine eingesetzte Gasflasche entleert werden kann. Durch die Entleerungseinrichtung wird der Inhalt einer eingesetzten Gasflasche insbesondere dann entleert, wenn eine Störung festgestellt worden ist. Ergibt beispielsweise eine Gasdichtigkeitsprüfung, dass die gefüllte Gasflasche nicht dicht ist, so wird die Gasflasche durch die Entleerungseinrichtung entleert. Risiken werden so weiter verbessert verringert.In one embodiment of the invention, the filling station comprises an emptying device with which an inserted gas cylinder can be emptied. By the emptying device, the contents of a gas cylinder used in particular emptied when a fault has been detected. If, for example, a gas-tightness test shows that the filled gas cylinder is not tight, the gas bottle is emptied by the emptying device. Risks are reduced so further improved.
Die Entleerungseinrichtung umfasst in einer Ausgestaltung einen insbesondere verfahrbaren Absaugkopf. Der Absaugkopf kann vorzugsweise horizontal und/oder vertikal verfahren werden, um diesen geeignet mit einer Armatur einer Gasflasche verbinden zu können. Der Absaugkopf weist vorzugsweise eine Ventilöffnungseinrichtung, insbesondere einen so vorstehenden Dorn oder Stutzen auf, dass mit der Ventilöffnungseinrichtung, also insbesondere mit dem Dorn oder Stutzen, durch ein Verbinden mit der Armatur ein entsprechendes Ventil der Gasfalsche geöffnet wird bzw. ein Ventilkörper der Gasflasche durch den Dorn oder Stutzen gegen eine Federkraft derart bewegt wird, dass das entsprechende Ventil geöffnet wird. Im Anschluss an das Öffnen des Ventils kann abgesaugt und so die Gasflasche entleert werden. Im verbundenen Zustand ist das Ventil dauerhaft geöffnet.The emptying device comprises in one embodiment a particular movable suction head. The suction head can preferably be moved horizontally and / or vertically in order to be able to suitably connect it to a fitting of a gas cylinder. The suction head preferably has a valve opening device, in particular a spike or socket projecting in such a way that a corresponding valve of the gas fals is opened with the valve opening device, thus in particular with the mandrel or socket, by connecting to the valve or a valve body of the gas cylinder through the valve Mandrel or nozzle is moved against a spring force such that the corresponding valve is opened. After opening the valve, it is possible to aspirate and empty the gas cylinder. In the connected state, the valve is permanently open.
In einer Ausgestaltung gibt die Freigabeeinrichtung die Gasflasche im Anschluss an eine solche Entleerung frei, damit die defekte Gasflasche vom Verbraucher im vollständig entleerten Zustand entnommen werden kann. Vorzugsweise gibt es eine Signaleinrichtung, die dem Verbraucher dann den Defekt bzw. die Störung anzeigt und ihn darüber informiert, dass die Gasflasche nicht weiterverwendet werden kann und/ oder an einer dafür vorgesehenen Abgabestation abgegeben werden sollte.In one embodiment, the release device releases the gas cylinder following such emptying, so that the defective gas cylinder can be removed by the consumer in the completely empty state. Preferably, there is a signaling device which then indicates the defect or malfunction to the consumer and informs him that the gas cylinder can not be used further and / or should be delivered to a dispensing station provided for this purpose.
Vorzugsweise gibt es zusätzlich zum Absaugkopf einen Befüllungskopf, der keinen so vorstehenden Dorn oder Stutzen aufweist, dass durch diesen das vorgenannte Ventil geöffnet werden kann.
