Abstract:
An apparatus and system is described for storing high-pressure fluids such as hydrogen. An inner tank and pre-stressed concrete pressure vessel share the structural and/or pressure load on the inner tank. The system and apparatus provide a high performance and low cost container while mitigating hydrogen embrittlement of the metal tank. System is useful for distributing hydrogen to a power grid or to a vehicle refueling station.
Abstract:
An LNG filling apparatus that can safely fill LNG in LNG vehicles. A filling apparatus 1 for filling LNG in an in-vehicle tank, the apparatus 1 having a housing 2, a recovery hose 41 and a filling hose 51 separately led from the housing, a recovery mechanism 4 for recovering a natural gas from the in-vehicle tank via the recovery hose, and a filling mechanism 5 for filling LNG to the in-vehicle tank via the filling hose. Separately leading the recovery hose and the filling hose from the housing with these hoses in close proximity to each other allows a range capable of filling that is the overlap range between a connectable range of the recovery hose and a connectable range of the filling hose to be enlarged. A single hose led from the housing can be used for both of the recovery of the natural gas and the filling of the LNG, which prevents tangle of hoses with each other, and enables to fill the LNG in the in-vehicle tank safely.
Abstract:
Shut-off valve for a pressure accumulator vessel for a medium, wherein a valve housing has a valve chamber with an intake opening and an outlet opening facing the pressure accumulator vessel, a movable piston, and at least one spring, wherein the piston has at least one axial connecting channel and is guided in an axially movable manner by at least two sealing elements arranged in the valve chamber, wherein a first effective piston surface of the piston, the first effective piston surface facing an inlet region of the valve chamber, and a sealing body form a valve seat, and wherein, by changing the pressure in an accumulator region of the valve chamber, the accumulator region being adjacent to a second effective piston surface, the piston is axially movable and a passage opening arranged between the intake opening and the outlet opening may be reversibly closed and opened, wherein, in the unpressurized state, the passage opening is kept open by the spring.Pressure accumulator system for a vehicle, comprising at least one pressure accumulator vessel and at least one shut-off valve, which is operatively connected thereto.
Abstract:
A method and a toolset for manufacturing a metal liner for a composite vessel includes a mandrel configured in several mandrel elements forming support elements of primary parts constituting the metal liner.
Abstract:
A ventilation gas management system and process for an enclosure adapted to contain fluid supply vessel(s) and through which ventilation gas is flowed to provide safe operation in the event of leakage of fluid from a vessel. Ventilation gas flow is modulated to accommodate various hazard levels associated with the deployment and operation of such enclosure containing fluid supply vessel(s), e.g., a gas box or gas cabinet in a semiconductor manufacturing facility, thereby achieving reduction in ventilation gas requirements otherwise required for such deployment and operation.
Abstract:
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.
Abstract:
According to embodiments of the invention, systems, apparatuses, methods and devices are provided for controlling accidental discharge of pressurized gases from entry point of a pressurized tubular member containing the pressured gases. In one embodiment, an apparatus is provided that includes a tubular member and a tubular port body. The tubular member holds the pressurized gases in an at least a partial gas phase and the tubular port body is threaded to an upper part of the tubular member in a sealed position. The apparatus may also have a dual channel valve top assembly and a discharge route. The dual channel valve top assembly can be disposed within the tubular port body. A first port is utilized to fill the tubular member with a pressurized gas, and a second port in gas communication with an entry point of the tubular member to discharge the pressurized gas.
Abstract:
The present invention describes methods and systems of oxygen transfill that includes the step of delivering a quantity of liquid oxygen to an evaporation chamber in a liquid oxygen evaporation device. Next, at least a portion of the liquid oxygen in the evaporation chamber is evaporated and a quantity of gaseous oxygen is maintained at a predetermined pressure level in the evaporation chamber. The method includes filling a portable compressed oxygen device with at least a portion of the gaseous oxygen.
Abstract:
The present invention provides a technique for suppressing an occurrence of weld in a pressure vessel liner. A film gate for molding a pressure vessel liner is located on a radially outer side of an outer peripheral end portion of an meshing portion in the pressure vessel liner. By disposing the film gate on the radially outer side of the meshing portion with a sufficient space between, it is possible to control the flow rate of the molten resin during molding, thereby suppressing an occurrence of weld.
Abstract:
A gas cylinder (100) in the neck (20) of which is installed a balanced valve (26). The valve is fitted in the outlet of the cylinder and its output emerges into a recess (22) which opens to the top surface (23) of the cylinder. Thus the valve is protected from physical damage. A thread (27) in the bore enables the attachment of fittings such as a regulator or a filling device (not shown) which cooperate with the valve (26) to control passage of gas from or into the cylinder.
