Described is a cylinder (1) for high pressure compressed fluids comprising a first hollow body (2) having an opening (2a) towards the outside (100) forming with the relative internal cavity a first housing space (2b) for a compressed fluid; at least one second hollow body (3) having an opening (3a) towards the outside (100) and forming with the relative internal cavity a second housing space (3b) for a compressed fluid which is separate and different from the first housing space (2b). The second hollow body (3) is housed inside the first hollow body (2) in such a way as to define a first housing chamber (6) and a second housing chamber (7). The first and second chambers (6, 7) have, respectively, an opening (2a, 3a) towards the outside (100) at the head end (4) of the cylinder (1) and at least the first or the second hollow body (2, 3) has at a bottom end (5) a bottom opening (“C”) which is normally closed.
摘要:
A gas storage container may be filled with gas under pressure by feeding cryogenic fluid comprising liquefied gas into the container through a first conduit arrangement in a nozzle inserted into a passageway through a fluid flow control unit mounted in an opening in said container; closing the container to the passage of gas into or out of said container; and allowing said cryogenic fluid to become gaseous within the closed container. The invention involves venting displaced air and/or gaseous cryogenic fluid from said container during the feeding step through a second conduit arrangement in the nozzle. In embodiments in which displaced air and/or gaseous cryogenic fluid flows through the second conduit arrangement around a length of the first conduit arrangement, heat transfer from the fluid flow control unit to said cryogenic fluid is suppressed thereby reducing the level of evaporation of the cryogenic fluid in the nozzle during fill.

A boss (1) for a composite pressure container for fluids is disclosed, in which the radial thickness of a lip (23) of the boss arranged between the coupling or valve member (5) and an imbedded member (2) is especially adapted to the intended pressure inside the container.
摘要:
A gas supply pipeline system having at least two outlets which are designed in each case for different pressures, for example for 300 bar and for 200 bar. For this purpose, at least one of the outlets is equipped with a valve for pressure reduction. In this way, the extraction of gas at different extraction pressures is possible with one arrangement.

Embodiments of the invention relate to a reservoir assembly for use in a device, such as a fuel cell system, hydride storage system, hydrogen compressor system, heat pump system or air conditioner system. The assembly includes a first cellular component interconnected with at least a second cellular component in which the interconnected cellular components are arranged together to substantially fill an available device space, one or more end caps coupled to a portion of the first or the second cellular components, one or more external ports for adding or removing a fluid from the reservoir in which the external ports are positioned in one or more of the end caps or cellular components, and one or more internal ports in which each internal port fluidly connects the first interconnected cellular component to at least the second interconnected cellular component.
摘要:
There is avoided a phenomenon where owing to an influence of a stepped portion of the surface of a helical layer positioned in an inner layer of an FRP layer, a fatigue strength of a layer (especially, a hoop layer) adjacent to the outside of the helical layer lowers. To realize this, there is disclosed a tank comprising a liner, and an FRP layer constituted of hoop layers and helical layers alternately formed by winding fiber bundles around the outer periphery of the liner, and in at least one of a plurality of helical layers positioned in an inner layer of the FRP layer, a sectional area of the fiber bundle constituting the helical layer is set to be smaller than that of the fiber bundle constituting another layer formed outside the helical layer. When the helical layer is formed by using this fiber bundle having the small sectional area, unevenness in the helical layer becomes small, and the unevenness can be prevented from being transferred to the other layer (e.g.,the hoop layer) formed outside the helical layer.
摘要:
A pressure vessel has a composite shell; a boss defining a port in the composite shell and having a neck; and an interface element disposed between the composite shell and the boss. The interface element is neither bonded to the composite shell nor to the boss, thereby allowing for movement between the interface element and the composite shell and allowing for movement between the interface element and the boss. The interface element further includes a neck disposed adjacent the neck of the boss.
摘要:
Method for processing at least one piece of data relating to a transportable cylinder of gas under pressure or a set of cylinders of this type (pallet of cylinders), characterized in that the said method comprises stages consisting in: transmitting a radio frequency signal containing the said data; receiving the said radio frequency signal and extracting the said data from it; measuring the strength of the signal received and deducing from this information about the location of the said cylinder or set of cylinders; and processing the said data as a function of the said location information, the said radio frequency signal being transmitted by an electronic module fitted to the cylinder or to equipment intended to be connected to the cylinder(s), including: a valve, a regulator, and/or a gas panel.
摘要:
Methods for loading a compressed fluid, such as natural gas, into and discharging the compressed fluid out of containment are provided. The compressed fluid is injected into a bottom portion of a container system for storage and/or transport until a target pressure is reached after which gas is withdrawn from an upper portion of the container system at a rate to maintain the target pressure while the compressed fluid is injected in the bottom portion. The compressed fluid is cooled through an expansion valve and by refrigerated chillers or by injecting a cold liquid of the same chemical composition as the compressed fluid, such as liquid natural gas, into the compressed fluid prior to injection into the container system. Withdrawal or discharge from the container system to a receiving facility begins with blow down from the bottom portion of the container system without a displacement fluid and continues until pressure falls below an acceptable differential pressure. The discharge stream is passed through a separator and a light gas from the separator is pressurized and injected into an upper portion of the container system to drive the compressed fluid out the bottom. The light gas is pressurized using either a compressor or a heated tank system, where two vessels operate in parallel, trapping and heating the light gas and then discharging to the container system from one while filling the other and alternating the operation between the two.
