請求項第１項記載の遮断弁。[Claims for Utility Model Registration] A valve hole 3 is provided in the middle part of the flow path 2 passing through the valve body 1.
A valve seat 4 connected to the valve seat 4 is provided, and the flow path 2 is divided by the valve seat 4 into an upstream flow path 2A and a downstream flow path 2B including the valve hole 3. In a shutoff valve equipped with a valve body 5 that controls the opening area, the valve body faces the valve hole 3 on the downstream side of the contact portion A of the valve body 5 with the valve seat 4 when the valve seat 4 is closed by the valve body 5. A cutoff valve is formed by opening a pressure introduction path 20 connected to the atmosphere or to the downstream flow path 2B on the outer periphery of the valve. The cutoff valve according to claim 1, wherein a plurality of pressure introduction passages 20 are opened on the outer periphery of the valve body. 2. The shutoff valve according to claim 1, further comprising a one-way control valve (21) disposed in said pressure introduction path to allow only fluid to flow into the valve hole (3).
