とする高圧ガス容器用弁。 The auxiliary valve seat, which is formed upstream of the main valve seat at the upper edge of the inflow channel that communicates with the discharge channel of the valve body attached to the high-pressure gas container via the valve chamber, is used to prevent overflow gas caused by earthquakes, disasters, etc. In the valve for a high-pressure gas container, a shutoff valve that automatically closes when the valve is closed is floatably disposed in the inflow channel, and a valve stem for the gas flow and the shutoff valve is disposed in the middle of the inflow channel. A ball receiving member for regulating the movement of the shutoff valve, which can be inserted through the member and has a reverse funnel-shaped recess formed in the center of the lower surface to receive the ball for regulating the movement of the shutoff valve, is placed near the end of the inlet in the inflow passage. A cutoff valve support member through which gas can flow and the valve stem of the cutoff valve can be inserted is installed and fixed, and the valve stem of the cutoff valve can be moved up and down between the ball receiving member for regulating the movement of the cutoff valve and the cutoff valve support member. In addition, the valve stem is provided with a locking member that locks the cutoff valve to the cutoff valve support member during gas supply, and when the high pressure gas container is inverted, the reverse funnel of the ball receiving member for regulating the movement of the cutoff valve is provided. The ball for restricting the movement of the shutoff valve, which enters the recess and disables the operation of the shutoff valve together with the locking member, cannot escape into the space between the ball receiving member for restricting the movement of the shutoff valve and the shutoff valve support portion. A valve for a high-pressure gas container, characterized in that it is rotatably housed.
