Claims

[Claims for Utility Model Registration] 1. A valve body having a hole communicating with the pressure fluid on the primary side; A cylindrical valve set ring surrounding the top outer periphery of the valve body; Placed on the valve set ring. a valve seat placed in a space formed by the valve body, the valve set ring, and the valve; and adjustable external force applying means for applying a predetermined set pressure on the valve. ;In a valve opening/closing device in which the valve is opened when the fluid pressure on the primary side exceeds a set pressure, the gap in the radial direction between the top outer periphery of the valve body and the cylindrical valve set ring is made small. ; The tip of the valve protrudes into the inner circumferential wall of the valve ring, and the radial gap between the two is made sufficiently large so that the area of the outlet of the valve is larger than the blowout area, and the external force applying means is connected to the blowout. A valve opening/closing device characterized by being arranged so that fluids do not come into direct contact with each other. 2. The valve opening/closing device according to claim 1, wherein a groove is provided on the outer periphery of the top of the valve body.
