とする磁気式緊急遮断弁。 A floating platform having a cylindrical shape and a hole bored in the side surface is disposed inside the casing having an inflow hole and an outflow hole on the side of the inflow hole, and a magnetic valve is disposed on the side of the outflow hole. a position where a seat is disposed, a magnetic valve is located inside the casing, and the magnetic valve is attracted to the upper surface of the floating platform to close the upper surface;
movable between a position where it is attracted to the magnetic valve seat and closes the outflow hole; further, an annular auxiliary valve is disposed on the floating platform so as to be movable in the vertical direction surrounding the floating platform; When the pressure of the fluid is below the set value, the fluid flows out from the outflow hole through the hole in the floating platform, between the floating platform and the annular auxiliary valve, and between the magnetic valve and the large diameter hole, and the fluid flows out from the outflow hole to reach the setting value. When this value is reached, the auxiliary valve rises and closes the space between the magnetic valve and the large diameter hole, so that fluid acts only on the magnetic valve, and after the magnetic valve is separated from the floating platform, the magnetic valve closes. A magnetic emergency shutoff valve, characterized in that the valve is attracted to a seat and the outflow hole is closed to prevent fluid flow.
