ト弁１が閉弁状態になるようにした安全弁装置。 A safety valve device that opens by a manual opening operation and closes when a gas leak occurs on the downstream side includes a lift valve 1 having a valve shaft 14, and a lift valve 1 provided at the tip of the valve shaft 14. 2 permanent magnet 3;
Furthermore, a first permanent magnet 2 faces the second permanent magnet 3 from the tip direction of the valve shaft 14 and rotates so that the magnetic poles facing the specific magnetic poles of the second permanent magnet 3 are reversed to N and S. an auxiliary valve 5 inserted in series with the lift valve 1 and biased in the valve opening direction by a first spring 52; and a leak hole 5 formed in the auxiliary valve 5.
1, a lock member 7 that is driven by the pressure in the flow path downstream of the auxiliary valve 5 and projects into the rotation space of the rotating first permanent magnet 2 to lock it in a non-rotating state; , a common operating member 8 is provided for simultaneously rotating the first permanent magnet 2 and opening the auxiliary valve 5, and the first and second permanent magnets 2 and 3 have different polarities facing each other. The safety valve device is configured such that the lift valve 1 is in the closed state in the adsorption state.
