に維持するようにした安全弁装置。 In a safety valve device that is opened by a manual opening operation and closed when a gas leak occurs on the downstream side, the second spring 20 is opened by a manual push-in operation.
an auxiliary lift valve 15 that is closed against the pressure and has a leak hole 21;
A main lift valve 1 is disposed coaxially with the auxiliary lift valve 15 on the upstream side thereof and is pushed open in conjunction with the push-close operation of the auxiliary lift valve 15, and the main lift valve 1 is biased in the closing direction. A first spring 16, an electromagnet M that holds the main lift valve 1 in an open state, and a sensor that operates by detecting a pressure increase in the flow path downstream from the flow path closing portion of the auxiliary lift valve 15. A safety valve device is provided with a pressure switch 18, and the electromagnet M is kept energized by the output signal of the pressure sensitive switch 18.
