Definitions

  • 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.
  • the valve When the valve is closed, the valve largely prevents the escape of gas, such as hydrogen, through the valve.
  • gas can be removed from the gas cylinder or gas can be introduced.
  • 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.
  • gas cylinders can also be disconnected from the system and replaced.
  • a bottle connection thread EN 629-1 / W21, 8 DIN 477 T1 is used for a gas cylinder bundle consisting of 12 gas cylinders filled with hydrogen.

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.

  • 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.
  • 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.
  • 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.

  • a filling of the transportable, refillable gas cylinder bundle is possible at any time by using the appropriate line.
  • suitable screw connections 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.
  • TRGS 500 A permanently technically dense compound is to be understood here as a compound that i.S.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 Appendix 2 as components with a process index of 0.25, i. technically sealed components, among other ball valves, which are proven according to No. 5.2.6 TA-Luft as equivalent sealing system to high-quality sealed metallic bellows with downstream safety gland or valves with bellows seal or membrane seal and NPT thread with a nominal diameter less than or equal to DN 50 and cutting - and clamping ring connections with a nominal diameter smaller than or equal to DN 32.
  • the gas supply extends and continues away.
  • the gas cylinders are not direct connected with the Fort Juli.
  • 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 valve system line is then to be understood as the lumen within the connecting piece, which lies between the two gas line connections.
  • valve system allows a permanently technically tight connection, for example, a portable, refillable gas cylinder bundle.
  • a continuous leak-tightness control of the gas cylinder bundle connected via the valve system can be dispensed with.
  • This brings a considerable cost and expense advantage over the otherwise necessary continuous monitoring of leaks 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 over the first gas line connection both a permanently technically tight connection with a first line for supplying a gas collector is possible, as well a non-permanently technically tight connection with commercially available gas lines for filling the portable, refillable gas cylinder bundle, whereby the variant of the valve system is compatible with systems of the prior art.
