Claims

[Scope of utility model registration request]

As a gas main valve, only a lift valve is used, and a combination of a lift valve and a cock is used, and the lift valve is opened and closed by an operating part or an interlocking part thereof, and an overflow prevention valve is provided on the upstream side of the Nuft valve. is inserted, and the lift valve is held in the fully open state only when the operating part is in the fully open position, and when it leaves the fully open position or the vicinity thereof, the lift valve becomes fully closed, and the lift valve is in the fully closed or fully closed position. A gas source valve of an overflow prevention valve material, which allows the ball valve of the overflow prevention valve to be reset by the lift valve directly or through an interlocking means during the return process.
