Valve assembly for gas cylinder |
摘要 |
A gas inlet (4) an inlet passage (8), a stop valve (7), an outlet passage (9) and a gas outlet (5) are communicated orderly with one another within a valve casing (3). The outlet passage (9) is communicated with the inlet passage (8) through a gas charging passage (10). A check valve (11) for blocking a flow from the inlet passage (8) to the outlet passage (9) is arranged in the gas charging passage (10). When a vacant gas cylinder (1) is charged with a high-pressure gas, the charge gas is supplied to a gas charging mouthpiece (17) connected to the gas outlet (5) while the stop valve (7) is kept closed. Thereupon, an interior space (A) of the gas cylinder (1) is charged with the charge gas from the outlet (5) through the check valve (11) and the gas inlet (4) in order. |
