阻止されることを特徴とする磁力式緊急遮断弁。 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;
It is movable between a position where it is attracted to the magnetic valve seat and closes the outflow hole, and a plurality of holes are bored in the closed upper surface of the levitation platform, and a plurality of holes are formed in the closed upper surface of the levitation platform. An auxiliary valve is installed that can move up and down accordingly, and when the fluid pressure is below the set value,
The fluid flows out from the outflow hole through the hole in the upper surface of the auxiliary valve and the hole in the floating platform, and when the set value is reached, the auxiliary valve rises and flows only to the magnetic valve through the hole in the auxiliary valve. The magnetic emergency shutoff valve is characterized in that, after the magnetic valve is separated from the floating platform, it is attracted to the magnetic valve seat, the outflow hole is closed, and the flow of fluid is blocked.
