摘要： PROBLEM TO BE SOLVED: To provide a gas interruption device which can attain positive interruption of a gas supply passage and elimination of troublesome management with a simple structure by utilizing pressure of gas flowing to the target position through a gas supply passage as operation pressure for interruption, without external operation nor electric driving method. SOLUTION: An opening/closing valve 31 is arranged on the way of a communication passage 33c located between an inlet side and an outlet side of gas in a gas supply control device, and has a valve body which rises/falls inside the communication passage 33c for opening and closing the communication passage. A gas taking-in part 32D communicates with a gas outlet side of the gas supply control device. A pressure holding valve 32 is operated for interrupting the communication passage 33C, when the pressure of the gas taking-in part 32D reaches a specified value or more, by applying the pressure to a valve body 34 of the opening/closing valve 31. The pressure holding valve 32 is provided with a structure 40A for applying the case of more than stationary pressure flowing through the gas supply control device to the valve body 34 of the opening/closing valve 31 directly.

SOLUTION: A plurality of high pressure vessels 10 are arranged on the input side. Gas in one high pressure vessel 10 selected therefrom is inputted, and a pressure is reduced to a final pressure by pressure reducing parts 12 and 13 in a plurality of stages. The gas is introduced in a heat exchange part 14 and correction processing of temperature is effected. A second connection part 51 taking out and introducing gas having a pressure higher than the final pressure is arranged in a piping route, followed by the pressure reducing part 13 to reduce a pressure to the final pressure, differently from a first connection part 50. Introduction of gas having a pressure reduced to the final pressure and take-out of gas having a pressure higher than the final pressure are effected. When the pressure reducing part 12 reaches an abnormal pressure, supply of gas having the pressure is stopped by an emergency cut-off part and discrimination from an external part is practicable by an alarming device operated by the gas.
