A plastic pressure vessel having an access fitting 10 is disclosed. The pressure vessel has a liner 30 defining a container with an access opening. The fitting 10 comprises a body portion 12 defined by a hollow cylindrical neck portion 14 having an upper annular rim 16 and a radially flaring flanged portion 18. The fitting 10 further comprises a plastic covering portion 20 surrounding the neck portion 14 and covering and conforming to an upper surface of the flanged portion 18 and conforming to the upper annular rim. The body portion 12 is formed from a plastic material having a higher tensile modulous and higher deflection temperature than the plastic covering portion 20 which forms a fusion bond with the liner 30.

摘要:
A valve for closing a container and for enabling the container to be filled has a housing (20) with an inlet port (30) and an outlet port (40). A closing member (60) is provided for sealingly closing the valve at the inlet port (30). At least one valve member (70) is provided for controlling fluid communication between the inlet port (30) and the outlet port (40). The valve member only allows fluid communication when it is in a first position. The valve member (70) is designed in such a way that it is brought into and maintained in said first position only if a predetermined filling condition is achieved. The filling condition is typically achieved, when the filling pressure of a system for filling the container (50) is initially below a first predetermined or predeterminable threshold value.

The invention relates to a pressure vessel (20) for a pressurized medium which is capable of flow, comprising a first reinforcement (22) composed of fibers which are applied as a winding and which are embedded in synthetic resin, wherein in addition to the first reinforcement (22), a second reinforcement (23) is provided, wherein the second reinforcement (23) has a percentage elongation at fracture which is lower than that of the first reinforcement (22), wherein the first reinforcement (22), considered alone, is sufficient to entirely absorb the forces resulting from the pressure of the medium in the pressure vessel (20), and wherein means are provided which are suitable for indicating a fracture of the second reinforcement (23).
摘要:
The storage tank for cryogenic liquids incorporates an ullage vessel that provides for an ullage space. The ullage vessel is in communication through an ullage line to a fill line that provides cryogen to a cryogen space. The junction where the ullage line and fill line meet is of a certain cross-sectional area. Downstream of the junction within the fill line, measured in reference to the direction of cryogen flow during a coruse of filling the cryogen space, is of a greater cross-sectional area than is the case at the junction. This creates a pressure reduction at the junction during a course of filling that causes a net flow of material from the ullage space over the course of filling. Once the cryogen tank is liquid full causing cryogen to be redirected down the ullage line, the smaller cross-sectional area of the ullage line compared to the fill line causes a reduction in flow of cryogen which is detected by the fill pump causing filling to stop providing the ullage space. A means of draining the ullage vessel prior to and during filling of the storage tank is provided.
摘要:
A high pressure fuel flow control device wherein pressure sensors are interposed on either side of the main restriction point of a refueling depot when the vehicle tank(s) to be refilled are interconnected in a flow circuit that connects the refilling depot and the vehicle tanks. The sensors measure pressure on the side of the depot tank[s] and pressure on the side of the vehicle tank at a restriction point in the gas flow circuit. Flow from a tank is complete and a tank is switched when the difference in the pressures sensed on opposite sides of the restriction point approaches zero or slightly greater than zero.
