In the first step, the gas in the first tank body is supplied to a gas consuming device through a first gas supply pipe by bringing the first gas tank into the first state. In the second step, the first gas tank is brought from the first state to the second state after the gas amount in the first tank body is reduced to less than a predetermined reference a amount. In the step, the first gas tank is brought from the second state to the third state after the gas in the first gas supply pipe has been consumed by the gas consuming device and the pressure of the gas in the first gas supply pipe has been reduced to less than a predetermined reference pressure.

Valve device is provided with poppet valve for opening and closing flow path. Thread part is formed on shaft of this poppet valve, and driving gear is screwed into this thread part. Driving gear is rotated via pinion by motor, and thereby the poppet valve is moved to advance and retreat so as to control opening and closing of the flow path. Driving gear is provided so as to be able to advance and retreat in the axial direction of the pinion and the axial direction of the poppet valve while remaining engaged with pinion, and is normally held at a predetermined non-operating position by spring (biasing means). With this, even when the poppet valve is seated on the valve seat and has stopped moving, the driving gear moves, when further rotated, against the biasing force of spring from the non-operating position in the axial direction, and absorbs an impact that is applied to the driving means or the like. Damage of the driving means and the like due to the impact load can be prevented.
