Zur Lösung der Aufgabe, einen tragfähigen Kompromiss zwischen dem Berstdruck des Metallbehälters, den Sicherheitsvorschriften, der Flammentemperatur und den Herstellkosten anzugeben, wird erfindungsgemäss vorgeschlagen, dass a) der Metallbehälter (2) aus Aluminium mit einem Reinheitsgrad von mindestens 95 Gew.-%, einer Wanddicke ("dw") zwischen 0,6 und 1,5 mm und einem Berstdruck zwischen 40 und 80 bar besteht, b) der äussere Durchmesser des Zylinderabschnitts (3) zwischen 70 und 120 mm beträgt. c) die Füllung ("F") 60 bis 95 Gew.-% Propen und 5 bis 40 Gew.-% eines Butangases enthält, d) der Metallbehälter (2) einen Zylinderabschnitt (3) und einen kalottenförmigen Halsabschnitt (4) aufweist, in deren Achse (A-A) ein Entnahmeventil angeordnet ist, und dass e) der Halsabschnitt (3) zum Ansetzen eines Gasbrenners ausgebildet ist.
摘要:
A can container, wherein an easily breakable part broken when an internal pressure in the can container abnormally rises and the can container is deformed so that a dome part is projected to the outside of the can container is formed on the outer surface side of the dome part positioned just near the outer peripheral edge part of the dome part continued to caulking parts. For example, when the internal pressure in the can container is abnormally raised by heating, and the dome part is inverted from the outer peripheral edge part of the dome part of a bottom cover and deformed so as to be projected to the outside of the can container, the easily breakable part is broken, and the contents in the can container is released from the can container. Thus, even if the internal pressure abnormally rises, degassing can be performed without allowing a part of the can container to be blown off.

A pressure container for storing liquid or gaseous media, comprising a plastic core container (1) with at least one cylindrical collar (1.1), which is disposed with a radially outwardly protruding flange (3.1) in the radial space between a metal cylinder (2) inserted therein and a metal body (3) surrounding the collar (1a) on the outside, wherein the metal cylinder has at least one groove (4) which is open radially to the outside and into which an O-ring (5) which is pressed against the collar (1.1) is inserted to form a seal, wherein a metal fitting (2.1) is screwed with an external thread (2.2) into the end of the metal body (3) facing away from the metal cylinder, and wherein the plastic core container (1) and the flange (3.1) are encircled at least partly by a supporting sleeve (7) composed of a fiber composite. The metal cylinder (2) forms a one-piece component of the fitting (2.1), directly adjoins the external thread, and has a stepped smaller external diameter than the external thread (2.2).

An apparatus for storage and liberation of compressed hydrogen gas is provided. The apparatus includes a housing defining a chamber that includes a cartridge comprising an array of hollow microcylinders defining cavities for storage compressed hydrogen gas. Each microcylinder has at least one end sealed with a plug made of an easily meltable alloy. The apparatus also includes a hydrogen liberating tool configured for controllable liberating the hydrogen gas from the cartridge into the chamber; and a control system operatively coupled to the discharge valve and liberating tool, and configured for controlling operation thereof. According to another aspect of the invention, there are provided a system and method for filling a cartridge having an array of hollow microcylinders having open ends. The filling includes placing the cartridge into a chamber of an autoclave, and compressing the hydrogen gas in the chamber, thereby providing permeation of the hydrogen gas through the open ends into cavities of the microcylinders. Thereafter, the open ends are sealed with plugs made of an easily meltable alloy.

A pressure vessel is configured such that a plurality of liners 1 are juxtaposed with one another. Each liner 1 includes a tubular trunk 4, and end plates 5 for closing opposite end openings of the tubular trunk 4. Two adjacent liners 1 are integrally connected together via a connection member 2 provided therebetween. The interiors of the integrally connected two adjacent liners 1 communicate with one another via a communication path 3 formed in the liners 1 and in the connection member 2. The ends of connection-member-forming projections 16 provided respectively on the two adjacent liners 1 are butt-joined together, thereby forming the connection member 2. The two adjacent liners 1 have respective through-holes 17 extending from the inner surfaces of the two adjacent liners to the ends of the connection-member-forming projections 16, and the through-holes 17 of the two adjacent liners 1 establish communication therebetween, thereby forming the communication path 3. This pressure vessel can be installed without generation of dead space, can implement a large capacity, and can be reduced in material cost and weight.
