A combustible gas supply unit is for supplying compressed combustible gas to a dispenser. The combustible gas supply unit includes a high pressure gas facility for handling compressed combustible gas, a base plate having the high pressure gas facility installed thereon and a barrier supported by the base plate to surround at least a part of an outer periphery of the high pressure gas facility. A barrier is shaped to surround at least a part of an outer periphery of the high pressure gas facility and includes a part to be supported by a base plate having the high pressure gas facility installed thereon.

Disclosed in the present invention is a system and method for supplying acetylene to an apparatus using acetylene, the system having at least one acetylene storage apparatus and an acetylene content analysis apparatus. The system and method disclosed in the present invention can utilize the capacity of an acetylene cylinder to a higher degree; before the solvent impurity concentration in acetylene gas reaches a level where it is no longer suitable, a more accurate understanding of the usable acetylene amount in the acetylene storage apparatus can be gained through detection, thereby reducing the number of times that the acetylene storage apparatus is refilled and replaced, and lowering the user's total costs.

A tank filling system comprising a first filling coupler that couples to a first set of fittings disposed at a first tank end of a tank; a second filling coupler that couples to a second set of fittings disposed at a second tank end of the tank; a fluid source; a set of fluid lines and one or more fluid valves that communicate fluid from the fluid source to the first and second filling couplers; and a computing device configured to control the one or more fluid valves. In some examples, the tank can comprise an elongated folded tank having a plurality of elongated rigid tubing portions having a first diameter, a plurality of connector portions having a second diameter that is smaller than the first diameter and flexible corrugations and a rigid cuff, and taper portions disposed between and coupling successive tubing portions and connector portions.

A gas cylinder cart includes a frame, a first control assembly composed of a first control panel wall and a first gas distribution assembly, a second control assembly composed of a second control panel wall and a second gas distribution assembly, and a central manifold connected to each of the first and second control assemblies. The central manifold includes a valve assembly allowing for connection of both the first and second control assemblies to gas cylinders, connection of only one of the first and second control assemblies to gas cylinders, or connection of the first and/or second control assemblies to remote gas sources. Inclusion of the first and second control assemblies within the gas cylinder cart allows for use of the gas cylinder cart in conjunction with different systems that might require different control assemblies.

Pressurized gas bottles with integrated valves, in which a plurality of functional supports are integrated in an extraction unit, are equipped with complex fall protection means. Moreover, in such a valve, a new approval procedure is carried out for the entire valve in the event of multiple modifications, for example when supplementing it with an additional function. In order to reduce the effort associated with this, an extraction fitting for a pressurized gas bottle is provided with a modular design, wherein a base module comprising the shut-off member and a fall protection device securing the shut-off member complies with legal requirements regarding fall protection and the shut-off device of the pressurized gas bottle. All further functionalities of the extraction fitting are integrated in at least one additional module, which is connected to the base module in a fixed but removable manner and without impairing the fall safety.

A stopper for fluid coupling and including a self-locking sheath designed to be slipped onto a connector, the sheath extending about a central longitudinal axis and including on its inner surface and at a first end, a tapped portion designed to engage with a mating threaded portion formed on the outer surface of the connector where the tapped portion includes at least one recess parallel to the longitudinal axis, where the inner surface of the sheath includes, at a second end opposite the first end, a spindle extending inside the sheath in a direction parallel to the longitudinal axis towards the second end of the sheath as far as a free end located between the first and second ends of the sheath, the free end of the spindle being designed to form a protective cover for a surface of the connector designed to engage with a filling tool.

A pressurized gas vessel port assembly incorporating a wall; a port extending through the wall; a nipple extending inwardly from the wall and having a hollow bore communicating with the port; a plug received within the hollow bore for movement between first and second positions, the plug residing at an inner end of the nipple at the first position and being displaced outwardly from the first position upon movement toward the second position; a venturi port opening the first nipple's hollow bore, the venturi being positioned outwardly from the first position for inducing an outward flow of the gas within the hollow bore; and incorporating a seat which outwardly overlies the venturi port, the seat being fitted for, upon a completion of the outward movement of the plug toward the second position, annularly contacting the plug and staunching the outward gas flow.

The present invention provides a Type 3 pressure vessel comprising a polar boss that is attached to a metallic liner and provides reinforced static strength, fatigue strength, endurance, chemical resistance and/or corrosion resistance of the liner orifice or neck region. In particular, the material of the polar boss has higher static strength, fatigue strength, endurance, chemical resistance and/or corrosion resistance relative to that of the liner material.

The invention relates to a valve for pressurized fluid, the valve having a body incorporating a fluid circuit having an upstream end and a downstream end, the circuit having a seal valve, the seal valve enabling the circuit to be opened or closed, the valve having a member for controlling the seal valve, the seal valve being slidably mounted in the body so as to slide between a position in which the circuit is closed when the control member is in a rest position and a position in which the circuit is open when the control member is in an active position, the valve having a deformable member positioned between the seal valve and the control member. The invention also relates to a container or a set of containers for pressurized fluid comprising such a valve.
