Claims

[Scope of Claim for Utility Model Registration] (1) The gas meter case is equipped with a shutoff valve that drives the valve held on the solenoid side to contact the valve seat in the event of an abnormality, and the gas meter , a gas meter with a built-in shutoff valve equipped with a return mechanism having an operation shaft that returns the valve in contact with the valve seat to the solenoid side, wherein the valve seat is formed at the tip of a cylindrical shutoff member, and the valve is inserted through the shutoff member. A gas meter with a built-in shutoff valve, characterized in that the valve is moved toward the solenoid side by the operating shaft. (2) The gas meter with a built-in shutoff valve according to claim 1, further comprising a flexible seal member that airtightly seals between the outer periphery of the shutoff member and the inner periphery of the gas flow path. (3) A shutoff valve is installed inside the gas meter case, which drives the solenoid to contact the valve seat in the event of an abnormality, and a valve held on the solenoid side is installed near the shutoff valve. In a gas meter with a built-in shutoff valve equipped with a return mechanism having an operating shaft that returns the valve to the solenoid side, the valve seat is slidable concentrically with a main valve seat fixed to the gas flow path. Consisting of a subvalve seat formed at the tip of a cylindrical shutoff member to be fitted,
The blocking member is fixed to the tip of the operating shaft, and the operating shaft moves the valve toward the solenoid through the blocking member, and the outer periphery of the blocking member and the inside of the gas flow path are connected to each other. A gas meter with a built-in shutoff valve, characterized in that it is provided with a flexible sealing member that airtightly seals between the gas meter and the surrounding area.
