Claims

[Scope of utility model registration request]

A storage space is formed in the gas tank main body, and an inlet and an outlet communicating with this storage space are formed, and a plug having a flow path is rotatably stored in the storage space, and a stopper with a flow passage is rotatably stored in the storage space. Install a safety valve,
Under normal conditions, the valve body of this safety valve is separated from the valve port by the elastic force of a spring, allowing gas to flow down.
In a gas tank that is designed to move toward the outlet side by supply gas pressure and close the valve port to stop gas supply in the event of an abnormality in which the pressure on the outlet side suddenly decreases, a protrusion protruding toward the outlet side on the valve body is provided. A gas tank characterized in that the protrusion protrudes into the flow path of the stopper in the event of an abnormality, and the stopper is provided with a flat cam surface that connects the outer peripheral surface of the stopper with the flow path.
