帰時用安全確認装置。 When measuring the downstream pressure (gas leak) of a gas valve installed in a gas conduit, a volume tank that has the same pressure as this downstream pressure is provided separately from the conduit, and the external conditions of this volume tank are The external conditions on the downstream side of the conduit are configured to be the same as the external conditions on the downstream side of the conduit, and a differential pressure gauge is connected to the volume tank and the downstream side of the conduit to determine the pressure difference between the pressure inside the volume tank and the downstream side. In addition to monitoring the pressure drop, the measurement time with the differential pressure gauge is set by a timer in accordance with the volume on the secondary side, and a buzzer sounds when the set time is reached, and the conduit is connected to the volume tank and A safety confirmation device for gas valve return that is configured to shorten the time required for safety confirmation by installing a slight differential pressure gauge and a bypass pipe that bypasses the gas valve.
