たことを特徴とする緊急遮断弁。 A cylindrical body is attached to a diaphragm provided in the valve body, and is coaxially and slidably inserted into a cylindrical part provided in the valve body, and is coaxially slidable on the cylindrical body. a valve body that is fitted and urged by a spring in a direction to close the flow path, the valve body has a circumferential groove recessed in the middle of the shaft part, and the cylindrical part A pair of grooves are formed on the upper and lower sides of the inner circumferential surface of the cylindrical body, and a plurality of holes are formed in the radial direction in correspondence with the grooves, and each hole has the circumferential groove. A ball that engages with the valve body is fitted into the valve body, and the diaphragm is operated by the abnormal pressure of the fluid flowing into the valve body, thereby moving the cylinder body in the axial direction,
An emergency shutoff valve characterized in that the engagement state of the ball engaged with the circumferential groove portion is released so as to maintain the flow path in an open state at all times.
