うにした手段を設けて成る緊急遮断弁。An emergency shutoff spring member is interposed in a pressure-accumulated state between the valve stem and a valve stem holding portion that holds the valve stem so as to be movable in the opening and closing directions of the valve. While a knob for rotation is provided, a split nut-shaped movable piece that is screwed onto the threaded part of the valve stem is attached to the valve stem holding part so that it cannot slide in the axial direction of the valve stem, and is not slidable in the axial direction of the valve stem. The movable piece is provided so as to be slidable in a right angle direction, and the movable piece is provided with means for operating the movable piece to a position where the piece is screwed into the threaded portion of the valve stem and a position where the piece is unthreaded.
