摘要:
The present invention provides a method and a system for handling gaseous fuels using sub-tanks (3) as gas emitting entities within a fuel tank (1). In particular the invention provides a system comprising an exchanger unit (2) for filling filled sub-tanks (3) to, and removing emptied sub-tanks (3) from, the fuel tank (1). Thanks to the invention the filling and removal is fast, efficient and safe.

Draining a cryogenic storage vessel to remove a pump is timing consuming, expensive and can result in increased greenhouse gas emissions. A cryogenic storage vessel comprises an inner vessel defining a cryogen space and an outer vessel spaced apart from and surrounding the inner vessel, defining a thermally insulating space between the inner and outer vessels. A receptacle comprises an outer sleeve and an inner sleeve, and defines passages for delivery of liquefied gas from the cryogen space to outside the cryogenic storage vessel. The outer sleeve intersects opposite sides of the inner vessel, with the opposite ends of the outer sleeve defining an interior space in fluid communication with the thermally insulating space that is sealed from the cryogen space. The inner sleeve has an open end supported from the outer vessel, and extends into the interior space defined by the outer sleeve, and a closed end opposite the open end, defining a receptacle space that is fluidly isolated from the thermally insulating space. A fluid communication channel extends from the cryogen space to the receptacle space, and can be selectively closed to allow the pump to be removed.

The invention relates to a gas distribution tap (1) comprising a base (2) and an internal gas pressure regulating system (20, 21, 22). A cap (12) surmounts the base (2), said cap (12) being movable with respect to the base (2) between at least a closed position in which the cap (12) pushes the pressure regulating valve (20) of the internal gas pressure regulating system (20, 21, 22) back against the valve seat (21) so as to completely shut off the pressure regulating orifice (22) and prevent any regulation of the gas, and a pressure regulating position in which the cap (12) allows the pressure regulating valve (20) to move away from the valve seat (21) by a given distance so as to uncover the pressure regulating orifice (22) and allow a reduction in pressure of the gas between the valve (20) and the valve seat (21). An elastic element (13) pushes elastically on the cap (12) in a direction that tends to move it away from the base (2) in order to cause it to switch from the closed position to the pressure regulating position. Gas container (30) equipped with such a tap (1) and use thereof for distributing the gas, notably oxygen.

A facility for delivery and treatment of cryogenic liquid, according to the invention comprises: - cryogenic equipment (6, 8) for delivering and treating the cryogenic liquid from the storage tank (2) to a container (4) to be filled, - an intermediate vessel (20) able to be supplied with cryogenic liquid from the storage tank (2) without passing through the cryogenic equipment (6, 8). The cryogenic equipment (6, 8) can be supplied with cryogenic liquid either by the storage tank (2), or by the intermediate vessel (20), and a link allows the fluid to be conducted out of the cryogenic equipment (6, 8) to the intermediate vessel (20).

A valve device includes: a poppet 84 that is formed in a hollow shaft shape except for a leading end, has a tapered closure part 91 at the leading end and a side hole 95 passing through a wall of the hollow shaft-shaped part, and rotates around the shaft center thereof during opening and closing actions; and a valve seat having a sloped seat surface with which the closure part 91 of the poppet 84 comes into contact when closing the valve device. The closure part 91 of the poppet 84 or the seat surface of the valve seat, whichever has a higher hardness, has a cut mark of the opposite direction from a direction of rotation of the poppet 84 around the shaft center that occurs during the valve closing action.
摘要:
A one-way valve device, and a non-return valve mechanism mountable on a non-way valve device allow a sufficiently high rate of flow under the pressure of upstream fluid around a predetermined pressure for retaining the residual pressure. A non-return valve cassette (200) for regulating flow of gas is arranged in a third space x3 defined in a flow channel (60) of a consumption valve (1) on a downstream side (Dd) of a middle transfer member (54) in the flow channel (60). The non-return valve cassette (200) contains a check valve (230), which is movable forward and backward between a valve-open position and a valve-closed position, and moves backward toward the valve-open position under the upstream pressure. The check valve (230) includes a cylindrical valve body (231) having a communicating channel (236), which connects an upstream side (Du) and the downstream side (Dd) of the valve body (231).
