Description

The invention relates to a valve system and more particularly to a transportable, refillable gas cylinder bundle connected via a valve system and to a gas cylinder assembly connected via a valve system.

Valves are known, for example, for closing gas cylinders and are used, for example, for filling and discharging the gas cylinders. When the valve is closed, the valve largely prevents the escape of gas, such as hydrogen, through the valve. When the valve is opened, gas can be removed from the gas cylinder or gas can be introduced. If multiple gas cylinders are arranged in a bundle, a valve system can be used to charge and discharge the gas cylinders. This makes it possible to simultaneously fill or discharge a plurality of gas cylinders connected via the valve system by means of a valve. This makes it possible, for example, to provide a larger storage volume. In addition, gas cylinders can also be disconnected from the system and replaced.

For a gas cylinder bundle consisting of 12 gas cylinders filled with hydrogen is typically a bottle connection thread EN 629-1 / W21,8 DIN 477 T1 used. The bottle connection thread is used to connect a gas supply line and to fill the gas cylinder bundle with hydrogen. Furthermore, a gas extraction line for the removal of gas from the gas cylinder bundle can be connected to the bottle connection thread. For safety reasons, valve systems that are not permanently technically leakproof must be continuously or permanently monitored and periodically serviced and inspected to ensure that no gas escapes from the valve system or gas cylinders or to monitor for leaks. In accordance with the Technical Rule for Hazardous Substances (TRGS) 500, the connections of the valve system that are not permanently technically tight and connections of the valve system with external lines, for example with a gas supply line, must be checked regularly. Due to the seal, the bottle connection thread EN 629-1 / W21,8 DIN 477 T1 has to be monitored and must therefore be permanently monitored. The TRGS 500 defines a process index between 0.25 and 4 which represents a process-related exposure potential remaining due to the technical solution. For a closed system, the process index must be 0.25 so that exposure is so low that monitoring is not necessary as a negligible amount of gas escapes.

The aim of the invention is to provide an improved valve system.

This goal is achieved by a valve system for a portable, refillable gas cylinder bundle and / or a gas cylinder assembly. The valve system has a first gas line connection, at least one second gas line connection and at least one valve system line, which permanently connects the first gas line connection and the at least one second gas line connection in a technically tight manner. The first gas line connection has a screw connection, which is designed to be permanently technically tight, and which is designed to permanently connect the first gas line connection to a first transmission line in a technically tight manner. The at least one second gas line connection has a screw connection which is suitable for permanent, technically tight connection and which is designed to permanently connect the second gas line connection with an outgoing line, a gas line connection unit and / or a gas cylinder in a technically tight manner. The valve system includes a port seal unit having a closed and at least one open state and arranged and configured to prevent gas flow through a lumen of the first gas conduit port in the closed state and gas flow through the lumen in the at least one open state allows the first gas line connection.

In this way, an arrangement of gas cylinders is achieved, which is reversible either permanently permanently technically tightly connected or portable with a not permanently technically tight connection, for example, with a gas filling system of a gas supplier, can be connected. With the help of the valve system so a total permanently technically tight transportable, refillable gas cylinder bundle and / or a technically dense gas cylinder assembly can be operated. The transportable, refillable gas cylinder bundle is thereby reversibly stationary or portable usable. On the one hand, the gas cylinder bundle can be permanently integrated in a stationary gas-tight composite in a gas cylinder assembly or permanently as a separate gas cylinder bundle technically tight, for example, as energy storage can be stored. On the other hand, the gas cylinder bundle can also be transported, for example, to a gas manufacturer or gas supplier in order to be filled there by means of a system which is not permanently technically tight, via a not permanently technically sealed gas filling line. Thus, the portable, refillable gas cylinder bundle can be used as Notenergiespeicher, which can be stored permanently and used as needed. A filling of the transportable, refillable gas cylinder bundle is at any time by using the appropriate line possible.

Under to permanently technically tight connection suitable screw connections here are threads, such as internal thread and external thread, and cutting ring and clamp connections to understand that allow a permanently technically tight connection. The threads may be NPT threads, for example.

A permanently technically dense connection is to be understood here as a connection that i. P. D. TRGS 500 is to be understood as technically dense, so has a process index of 0.25 and no permanent monitoring and regular check of tightness needed. The TRGS 500 lists in its Appendix 2 as components with a process index of 0.25, d. H. technically sealed components, among other ball valves, which according to no. 5.2.6 TA-Luft are proven as equivalent sealing system to high-quality sealed metallic bellows with downstream safety stuffing box or valves with bellows seal or membrane seal as well as NPT thread with a nominal size smaller than or equal to DN 50 and cutting - and clamping ring connections with a nominal diameter smaller than or equal to DN 32.

In this case, from the point of view of the gas cylinder, it is to be understood that the gas supply extends and continues away. In particular, the gas cylinders are not directly connected to the conduit. By contrast, for example, an outgoing line can lead to the gas cylinders and be connected directly to the gas cylinders. The outfeed lines are part of a gas cylinder bundle comprising a plurality of gas cylinders, while transfer lines are typically external gas lines which are connected to the gas cylinder bundles in order, for example, to fill or discharge them. The transfer lines can also be part of a gas cylinder network, via which several gas cylinder bundles are connected to one another. Between the outgoing lines and the forwarding connected to the first gas line connection, the optionally openable or closable connection sealing unit, for example a ball valve or the like, which is also part of the gas cylinder bundle, is arranged. By means of the connection sealing unit it can be controlled whether the discharges can lead gas from the gas bottles to the advances during unloading or, if during filling, the advances can lead gas into the gas bottles through the conduction connected to the first gas line connection.

The connection sealing unit is, so that the valve system is permanently technically tight, also permanently technically tight, for example in the form of a ball valve, a valve with a membrane seal, a valve with bellows seal or the like.

The valve system may be a valve system for a transportable, refillable gas cylinder bundle, in this case, the valve system comprises, for example, a valve system line which opens into a plurality of outfeed lines or which can be connected to a plurality of outfeed lines via a gas line connection unit. However, the valve system may, for example, also be a connection stub which contains the first gas line connection, the second gas line connection, the connection seal unit and the valve system line. The valve system line is then to be understood as the lumen within the connecting piece, which lies between the two gas line connections.

One aspect of the invention is that the valve system allows a permanently technically tight connection, for example, a portable, refillable gas cylinder bundle. As a result, a continuous leak-tightness control of the gas cylinder bundle connected via the valve system can be dispensed with. This brings a considerable expense and cost advantage over the otherwise necessary continuous monitoring of the tightness and possible air changes in the premises in which the gas cylinder bundle is set up. One aspect of a variant of the valve system is that a permanently technically tight connection with a first line for supplying a gas collector is possible via the first gas line connection, as well as a non-permanently technically tight connection with commercially available gas lines for filling the transportable, refillable gas cylinder bundle. whereby the variant of the valve system is also compatible with systems of the prior art.

In one embodiment, the first gas line connection to means for not permanently technically tight connection, which are designed to connect the first gas line connection with a second Fortleitung not permanently technically tight.

The second transfer line is, for example, a gas line for connecting to a hydrogen gas storage or a hydrogen generation device. This second transfer may have a gas line connection specified by a hydrogen supplier, which normally does not permit a permanently technically sealed connection.

In one embodiment, means for not permanently technically tight connection to a detachable and reconnectable adapter. The adapter is designed to be connected to the first gas line connection and has a third gas line connection. The third gas line connection has a non-permanently technically tight connection suitable second screw, which is designed to connect the third gas line connection with a second Fortleitung not permanently technically tight.

The adapter may comprise a detachable and reconnectable adapter gas connection unit. This is designed to be connected to the first gas line connection and has the third gas line connection. In addition, the adapter may include a detachable and reconnect adapter lead. The adapter-forwarding has in this case at a proximal end to a permanently technically tight connection suitable first adapter screw which is designed to be permanently connected with the permanently technically leakproof connection screw the first gas line connection technically tight. Furthermore, in this case, the adapter lead has a second adapter screw connection at a distal end, which is designed to be connected to the adapter gas line connection unit. Thus, in this case, the adapter may be formed by the adapter gas connection unit and the adapter feed line. Alternatively, the adapter can also be formed only by the adapter gas connection unit. In this case, the adapter gas connection unit is connected directly to the first gas line connection of the valve system.

As a further alternative variant, the adapter can also be formed only by a detachable and reconnect adapter-forwarding. In this case, the adapter-forwarding at a proximal end to a permanently technically tight connection suitable first adapter screw connection, which is designed to be permanently connected in a technically tight manner with the permanently technically tight connection suitable screw connection of the first gas line connection of the valve system. Furthermore, the adapter-forwarding in this case at a distal end to a not permanently technically tight connection suitable second adapter-screw connection, which is designed to be connected with a second Fortleitung not permanently technically tight.

In one embodiment, the adapter has or is connected to a valve system sealing unit, for example a shut-off valve. In the connected state of the adapter with the permanently technically tight connection suitable screw connection of the first gas line connection of the valve system, the valve system sealing unit is arranged to the connection sealing unit in series. The valve system seal assembly has a closed and at least one open condition and is configured to prevent gas flow through a lumen of the adapter in the closed condition and to permit gas flow through the lumen of the adapter in the at least one open condition.

In one embodiment, the means for not permanently technically tight connection to a second not suitable for permanently technically tight connection screw on, which is designed to connect the first gas line connection with a second Fortleitung not permanently technically tight. The second forwarding can be connected in this case either via the second not to permanently technically tight suitable screw or the adapter. In one embodiment, the means for not permanently sealingly connecting either the adapter or the second screw connection to connect the second lead to the first gas line connection.

The second not suitable for permanently technically tight connection screw can be an external thread, such as a bottle connection thread EN 629-1 / W 21.8 DIN 477 T1 be.

In one embodiment, at least one suitable for permanently technically tight connection screw is an internal thread. This embodiment comprises the case in which the screw connection of the first gas line connection which is suitable for a permanently tight connection is an internal thread and in addition the case that a screw connection of the second gas line connection suitable for permanently technically tight connection is an internal thread and also the cases that several Permanently technically tight Connect appropriate screw, for example, of several first and second gas line connections are internal thread. The female thread may be, for example, a National Pipe Thread (NPT) thread with a nominal value less than or equal to approximately DN 50. Also, all internal thread National Pipe Thread (NPT) threads with a nominal value less than or equal to approximately DN 50 can be. In this case, the screw connections of two components to be connected, which are suitable for permanent, technically tight connection, preferably form a combination of an internal thread and an external thread, which are matched to one another in such a way that a permanently technically tight connection is created when the male screwdriver fits into the internal thread is screwed in. For this purpose, additional seals may be included in the screw, such as rings, discs, blocks, wedges or the like made of elastic material.

In one embodiment of the valve system with a first gas line connection with external thread and internal thread, the external thread is formed to be connected to a second lead with a first outer diameter. The internal thread is in this case formed to be connected to a first lead having a second outer diameter which is smaller than the first outer diameter. A connection between the first propagation with the second outer diameter and the internal thread is permanently technically tight, while a connection between the first propagation with the first outer diameter and the external thread is not permanently technically tight and requires continuous monitoring of the tightness. To the external thread, for example, a second Fortleitung be connected, with the gas valve, such as hydrogen, can be supplied to the valve system. To the internal thread, a first Fortleitung be connected, which connects a gas cylinder bundle with other gas cylinder bundles, thus creating a gas cylinder assembly. This gas cylinder assembly can be used, for example, to operate a gas storage, from which then gas can be removed if necessary. For this purpose, either the first extension of the internal thread can be completed and a second extension can be connected or the valve system can be designed such that a removal is performed via the connected to the internal thread first forwarding.

In one embodiment, at least one suitable for permanently technically tight connection screw is a cutting ring connection or a clamping ring connection with a nominal value less than or equal to DN 32.

In one embodiment, at least one screw connection suitable for permanently and technically tight connection is a cutting ring compression fitting with a nominal value smaller than or equal to DN 32. In one embodiment, the first gas line connection and / or the second gas line connection has a cutting ring compression fitting with a nominal width smaller than or equal to DN 32. The cutting ring compression fitting of the first gas line connection and / or the second gas line connection can be the screw connection which is suitable for permanently and technically tight connection.

In one embodiment, the first gas line connection and / or the second gas line connection has a self-sealing pipe fitting.

The connection sealing unit can have a ball valve, which is proven to be equivalent according to No. 5.2.6 TA-Luft, a valve with bellows seal or membrane seal or another permanently technically sealed connection sealing unit. In this case, the connection sealing unit makes it possible to permanently close a lumen by the connection sealing unit in a technically tight manner.

In one embodiment, at least one of the screw connections suitable for permanently and technically tight connection is a National Pipe Thread (NPT) thread with a nominal diameter smaller than or equal to DN 50. This embodiment includes the case where the screw connections suitable for permanently and technically tight connection Internal thread with a National Pipe Thread (NPT) thread is and additionally the cases in which the permanently technically tight connection suitable screw is designed as an external thread.

The valve system can be designed to withstand a pressure of between 1.0 bar and 300 bar or a pressure of up to 700 bar. In one embodiment for stationary operation, the valve system is intended to be operated in a pressure range between 1.5 bar and 30 bar or up to 60 bar. In one embodiment for the portable operation, the valve system is intended to be operated in a pressure range between 5.0 bar and 200.0 bar or even up to 700 bar. In portable operation, a transportable, refillable gas cylinder bundle connected to the valve system is brought, for example, from a hydrogen supplier to a hydrogen storage facility where it is filled with hydrogen. Thereafter, this gas cylinder bundle can then be returned to a place of use, where it can be connected, for example, to a gas cylinder assembly, so that the hydrogen can be discharged from the gas cylinders in the gas cylinder assembly. The gas cylinder bundle can also be filled with a gas other than hydrogen or with a gas mixture.

In one embodiment, the valve system has at least one pressure gauge. The pressure gauge is used to determine the pressure in the valve system.

In one embodiment, an inner diameter of the at least one valve system conduit is less than or equal to about 8 mm. The inner diameter of the at least one valve system conduit may also be less than or equal to about 5 mm. In one embodiment, the feed lines to the gas cylinders have an inner diameter less than or equal to about 5 mm.

The invention is also found in a portable, refillable gas cylinder bundle at least one gas cylinder for storing gas, which has a valve system or permanently connected to a valve system is technically tight. The gas cylinder bundle can be, for example, a bundle of z. Example, typically 12 or 18 gas bottles act, which are all connected to each other via the valve system and have a common first gas line connection, can be removed via the gas from the gas cylinders of the gas cylinder bundle or can be supplied via the gas.

In one embodiment of the transportable, refillable gas cylinder bundle, a screwdriver of each gas cylinder of the gas cylinder bundle has a nominal value smaller than or equal to DN 50. This ensures that all connections of the valve system are permanently technically tight.

In one embodiment, all connections and connection sealing units of the gas cylinder bundle permanently technically tight, so that a permanent check the tightness z. B. is not necessary with the aid of a gas warning device.

The invention can also be found in a gas cylinder assembly which has at least two transportable, fillable gas cylinder bundles, each with at least one gas cylinder for storing gas. The at least one gas cylinder of the respective gas cylinder bundle is permanently connected in a technically tight manner to a respective valve system via a respective second gas line connection, and the valve systems of the respective gas cylinder bundles are connected to one another via at least one first transfer line. It can also be arranged several Fortleitungen between the valve systems of the gas cylinder bundle. It may also be a pressure reducer between two connected to the valve systems of the gas cylinder bundles Fortleitungen be arranged. This is the case, for example, when a portable gas cylinder bundle and a stationary gas cylinder bundle are operated together in a gas cylinder assembly, since the portable gas cylinder bundle preferably in a pressure range between 5.0 bar and 200.0 bar and the stationary gas cylinder bundle preferably in a pressure range between 1 , 5 bar and 30.0 bar is operated.

In one embodiment of the gas cylinder assembly, one of the gas cylinder bundles is firmly and permanently connected in a technically tight manner to a first transfer line and at least one of the gas cylinder bundles is detachably and reconnectably connected to a second transfer line. This is the case, for example, when the transportable, refillable gas cylinder bundle connected via the second transfer line is filled by a gas store outside the gas cylinder assembly.

1 shows a valve system 10p from the prior art, on a gas cylinder bundle 12 from twelve gas bottles 14 is arranged. The valve system 10p is not suitable for a permanently technically tight connection with a forwarding and requires a continuous or permanent monitoring of the tightness of the valve system 10p , In this case, from the point of view of the gas cylinder, it is to be understood that the gas supply extends and continues away. In particular, the gas cylinders are not directly connected to the conduit. In contrast, for example, an onward line to the gas cylinders 14 lead and directly with the gas bottles 14 be connected. The outgoing line can be connected to the valve system 10p be connected or part of the valve system 10p be. The forwarding can be a component of a stationary gas cylinder assembly (s. 8th ) that are external to the gas cylinder bundle 12 can be connected. The forwarding 42 is part of the portable gas cylinder bundle 12 ,

The gas bottle bundle 12 is of a metallic frame construction 16 Surrounded by the gas bottles 14 protects against shocks. This is the frame construction 16 higher than the individual gas cylinders 14 , The frame construction 16 is so high that the valve system 10p at the top of the gas bottles 14 can be arranged and the frame construction 16 the valve system 10p surmounted, so that in case of a possible accident, such as when the frame construction tips over 16 , first an interaction mainly with the frame construction 16 takes place and not with the valve system 10p or the gas bottles 14 ,

The valve system 10p has for filling and discharging the gas cylinders a first gas line connection 18p that's about the valve system line 20 with a second gas line connection 22 connected is. The gas line connection 18p is designed in the present case as a connecting piece, so that the valve system line 20 inside the connecting piece is located. The second gas line connection 22 is with a gas line connection unit 38 connected in the form of a hexagon block. From the gas line connection unit 38 leads a valve system line to an opposite gas line connection unit 38 and further, the gas line connecting unit 38 via further valve system lines and gas line connections with the gas cylinders 14 connected, thereby filling and discharging the gas cylinders 14 of the entire gas cylinder bundle 12 over the first gas line connection 18p is possible.

The first gas line connection 18p has an external thread 24 on, which allows a connection with a second transfer, for example, for filling or discharging. This in 1 shown external thread 24 is a bottle connection thread EN 629-1 / W21,8 DIN 477 T1 , The first gas line connection 18p Therefore, it can only be sealed by means of a flat gasket, which does not allow a permanently technically tight connection to a gas line. Furthermore, at the first gas line connection 18p a shut-off valve 26 arranged, which is a stream, for example of gas, in the with the first gas line connection 18p connected valve system lines 20 allow in an open state and can largely prevent in a closed state. The shut-off valve 26 does not allow a permanently technically tight closing of the first gas line connection 18p ,

To determine the in the valve system 10p existing pressure is a manometer 28 with the valve system 10p connected. The valve system 10p For example, it can be filled with hydrogen at a pressure of up to 200 bar or 300 bar. The manometer 28 detects the instantaneous pressure in the valve system 10p and thus enables, in addition to the pressure determination during the filling of the gas cylinder bundle 12 , a continuous check of the pressure in the valve system 10p , As a result, for example, easily recognizable when gas from the valve system 10p escapes, as this leads to a pressure drop in the valve system 10p leads.

2 shows a first embodiment of a valve system 10 , The valve system 10 is like the valve system 10p (S. 1 ) formed with a gas cylinder bundle 12 from twelve gas bottles 14 to be connected and has twelve second gas line connections 22b on. Alternatively, any other number of gas cylinders 14 , especially only one gas bottle 14 conceivable.

With the help of the valve system 10 can the gas cylinder bundle 12 be used reversibly stationary and portable. During portable use, a non-permanently technically dense gas line may be used to fill the gas cylinders 14 of the gas cylinder bundle 12 to the first gas line connection 18 of the valve system 10 be connected. In a stationary use is the gas cylinder bundle 12 permanently technically tight.

The first gas line connection 18 of the valve system 10 has this in contrast to the first gas line connection 18p who in 1 and in the valve system known from the prior art 10p is used, in addition to the external thread 24 an additional internal thread 30 on. This internal thread 30 is suitable for the permanently technically tight connection of a transmission line. The internal thread 30 is a National Pipe Thread (NPT) thread with a nominal diameter of DN 50. The internal thread 30 can also have a smaller nominal diameter than DN 50. The internal thread 30 For example, it can also be a ¼ "NPT thread. Alternatively, the internal thread 30 be replaced by a cutting and clamping ring connection with a nominal diameter less than or equal to DN 32, to allow a permanently technically tight connection with a first forwarding.

Furthermore, the valve system contains 10 in contrast to the valve system 10p out 1 a ball valve 32 that in contrast to the shut-off valve 26 out 1 a permanently technically tight closing of the first gas line connection 18 allows. Alternative to the ball valve 32 can also be a valve with a membrane seal, a valve with a bellows seal, a stem and stem sealing of fittings, such. Example, a plug valve, a valve, a flap, a slide or the like, for example, in conjunction with a bellows seal or a membrane seal or other connection sealing unit for closing the first gas line connection 18 be used, which is a permanently technically tight closing of the first gas line connection 18 allows. Furthermore, the ball valve 32 by means of a lever 34 be set in a 90 ° rotation between an open and a closed state. When closed prevents the inside of the ball valve 32 arranged ball a gas entering the gas line lumen 36 and exit of gas from the gas line lumen 36 , In the open state, gas can enter the gas line lumen 36 go in and out.

To the valve system 10 to fill with gas, a forwarding to the first gas line connection 18 connected (not shown). For this purpose, the ball valve 32 be set in the closed state, to prevent the escape of gas from the valve system 10 to prevent the environment. Having a connection between the conduction and the first gas line connection 18 was produced, the ball valve 32 be opened, reducing the gas from the conduction into the valve system 10 can flow as long as the pressure in the forwarding is higher than the pressure in the valve system 10 ,

The gas flows over the lumen 36 of the first gas line connection 18 through the ball valve 32 into the valve system line 20 , In the present first embodiment of the valve system 10 is the valve system line 20 within a connecting piece of essentially the ball valve 32 is formed, arranged. The valve system line 20 opens into a second gas line connection 22 equipped with a gas line connection unit 38 connected in the form of a hexagon block. The second gas line connection 22 is like the first gas line connection 18 Permanently technically tight in the connected state and has an NPT thread with a nominal diameter of DN 50. Also the second gas line connections 22 may have a NPT thread smaller than DN 50, or have a NPT thread with a size of DN 32 or less instead of an NPT thread. The gas line connection unit 38 is with an opposite gas line connection unit 38 connected (not shown).

The gas line connection units 38 are each about 6 second gas line connections 22a each with a forward line 42 connected the gas to the gas cylinders 14 connected second gas line connections 22b lead, over which the gas bottles 14 with gas, in the present case hydrogen, can be filled. Each of the gas line connection units 38 supplies 6 gas bottles each 14 , The forewords 42 in the present case have an inner diameter of 5 mm, a wall thickness of 1.5 mm and an outer diameter of 8 mm. The forewords 42 can also have other dimensions that allow a permanently technically tight connection. Like the second gas line connections 22 , are also the second gas line connections 22a and 22b in with the gas line connection units 38 and the gas bottles 14 Connected state permanently technically tight.

Furthermore, each is a manometer 28 at each of the gas line connection units 38 arranged. The manometer 28 allows pressure within the valve system 10 to monitor. Is that on the manometer 28 measured pressure equal to the pressure in the forwarding, is the filling of the gas cylinder bundle 12 essentially completed. In order to increase the pressure in the conduction, the to the first gas line connection 18 connected, a pressure pump or compressor can be used (not shown). Alternatively, gas can also be removed from the valve system by means of the pressure pump 10 be pumped (not shown).

The gas bottle bundle 12 serves to store the gas, ie in the present case for storing hydrogen. The gas bottle bundle 12 can be used for example as energy storage. For example, the energy may be in the summer when there is an excess of energy in the gas cylinder bundle 12 be stored and in winter, when energy is needed to be deprived of energy storage. For this purpose, hydrogen can be generated with the aid of, for example, solar panels, hydroelectric plants, wind power plants or other power plants generated electrical energy, for example, from water and the recovered hydrogen can be supplied to the energy storage, when an excess of electrical energy prevails. The gas bottle bundle 12 For this purpose, it can be part of a larger gas cylinder network 100 (S. 8th ) be. The gas bottle bundle 12 in this case is fixed about a first transfer with other gas cylinder bundles 12 and further comprising a system for generating or providing hydrogen (not shown). Furthermore, the gas cylinder bundles 12 of the gas cylinder network 100 connected to a power generating device which can generate energy by means of hydrogen, for example by combustion or by a fuel cell or by an internal combustion engine (not shown). When energy is needed, the hydrogen can bundle the gas cylinders 12 be removed and burned releasing energy. To ensure a largely lossless storage of hydrogen, it is therefore necessary a permanently technically tight valve system 10 to use.

3 and 4 show a second embodiment of the valve system 10 ' , For better visibility and understanding, this is valve system 10 ' in the 3 and 4 without gas bottles 14 shown.

The second embodiment differs from the first in 2 shown embodiment of the valve system 10 essentially through the first gas line connection and the connection to the gas line connection units 38 , In contrast to the first embodiment of the valve system 10 has the first gas line connection 18 ' a compression fitting 31 with which a first forwarding can be permanently connected in a technically tight manner. Furthermore, the first gas line connection 18 ' of the valve system 10 ' not in one directly with the gas line connection unit 38 connected connecting piece, but via the ball valve 32 with a valve system line 20 connected.

The valve system line 20 in the present case has an inner diameter of 8 mm, a wall thickness of 2 mm and an outer diameter of 12 mm. The valve system line 20 can also have other dimensions, the dimensions are to be chosen such that a permanently technically tight connection via the internal thread 30 is possible. The valve system line 20 forks in the illustrated embodiment of the valve system 10 at a valve system line crotch 40 and supplies the gas to two oppositely disposed gas line connection units 38 in the form of hexagonal blocks, each with a second gas line connection 22 the valve system line 20 are connected. The second gas line connection 22 is like the first gas line connection 18 Permanently technically tight in the connected state and has an NPT thread with a nominal diameter of DN 50. Also the second gas line connections 22 may have a NPT thread smaller than DN 50, or have a NPT thread with a size of DN 32 or less instead of an NPT thread.
