パイロット式安全弁。In a pilot-operated safety valve, in which a valve body that can be raised and lowered on the valve seat is loaded with pilot fluid pressure to keep it closed, a gas supply pipe is led from the outside to the pilot pressure chamber that loads the valve body. A plug for blocking the gas discharge port of the pipe is provided on a lever that can swing freely in the vertical direction, and a lever operation mechanism is provided on the valve body for operating the lever so that the plug is removed from the gas discharge port when the valve body is lowered. A pilot-operated safety valve characterized by the provision of a pilot-operated safety valve.
