Abstract:
A gas container 1 is disclosed including a pressure-proof container 3, accommodating a foam body 9 sharing more than 80% of an inner capacity of the container 3, and a valve 7 provided on a top of the pressure-proof container 3 for ejecting liquefied gas from the pressure-proof container 3. The foam body 9 is internally formed with a continuous hole 11 in communication with the valve 7 and the continuous hole 11 internally has a tube 53. The tube 53 has a distal end 53A that is located at a position L nearly half a filled-up volume of the pressure-proof container 3, and the tube has a distal end 53A that is disposed in a space portion 11A formed inside the continuous hole 11 in a non-contact state.
Abstract:
An ovoid flexible pressure vessel is described. At least one hollow pressure cell, formed of resilient material, a passageway, a valving means, a capillary tube, hoop winding, high-strength braiding material and at least one reinforcing ring are provided. The ovoid flexible pressure vessel has a pressure relief device comprising a reduction in thickness of the hollow pressure cell at a predetermined location whereby, when the hollow pressure cell is subjected to an overpressure condition it will fail at the predetermined location. Further pressure release devices include the following: a reduction in thickness of the cell, an indentation, a projecting member, a weakened section of the passageway, a weakening or an absence of high-strength braiding material or hoop winding at a predetermined location along the passageway, a weakening or spreading of fibers in either of the reinforcing panels or in either flexible blankets.
Abstract:
A flexible pressure vessel is constructed from at least one pair of upper and mating lower dome shaped cell portions. The dome portions are molded from sheets of resilient material and joined together by radio frequency welding or high-strength adhesives. Upper and lower passageway portions extend outwardly from each cell portion to the surrounding sheet material. When the cell portions are joined the passageway portions are joined to form a passageway for connection to a valve or another cell. Upper and lower rings surround the upper and lower cell portions to provide reinforcement for the cells. First and second blankets of heavy-duty fiber reinforced material are attached over the upper and lower cell portions and stitched in place with heavy-duty stitching extending through the resilient material surrounding the cell portions. Cell shaped sponges impregnated with absorbent materials are encased in liquid and gas impermeable plastic tubing and inserted into the cells prior to joining of the cell portions. Heat-reflecting plastic film or metal foil is inserted between blankets and the cell portions. The heavy duty stitching is high-pressure loop and lock braiding. The passageway has a cross-section of between 0.050 and 0.100 inches. An apparatus and method are described for constructing the flexible pressure vessel.
Abstract:
Filler elements for a tank of combustible fluid described herein are formed from a sheet of foil mesh material by a multiple fold technique. The folding process places the free edges of the sheet in the center of the filler element where they are protected and where any piece that breaks off will be trapped. The sides are first folded inwardly and then the ends are folded inwardly. Finally, this intermediate member is rolled, formed, molded or folded further into the final desired shape for the filler element. Folding is facilitated by use of a crushed crease along desired fold lines. To reduce nesting of the mesh, various sections of the mesh corresponding to the fold lines present openings of differing sizes.
Abstract:
Generally there is provided an expanded foil sheet having an array of openings in a pattern exhibiting a plurality of dimension, which sheets are rolled or stacked, such that juxtaposed openings differ in dimension, to form a thermal filler mass for a tank. Alternatively, two or more foil sheets, each exhibiting openings or a pattern of openings of dimension differing from the openings of adjacent sheets are combined in a roll or stack to form the filler mass. Finally, in a further feature, the filler mass is adhered to the tank wall.
Abstract:
PURPOSE: A gas storage structure and a gas storage device including the same are provided to easily inject gas into a gas storage unit and to discharge the injected gas when necessary. CONSTITUTION: A gas storage structure(100) comprises a gas storage unit(110) and an input/output control unit(120). The gas storage unit has an inner space for storing gas and has an opening. The opening connects the inner space and an outer space. The input/output control unit is installed in the opening and has a gate(122). The gas storage unit comprises a porous structure.
