The valve stem is formed into a gradually increasing deformation portion that gradually increases as it goes rearward from the tip, and the valve stem is brought into contact with the flexible orifice body! lIl
By adjusting the insertion critical position of the gradually increasing deformation part with respect to the valve hole, the area opening of the valve hole can be set to a desired size, and the constant flow can be controlled below the set flow rut value. The valve is known as Special Publication No. 52-22450,
Also, since the primary side edge of the valve hole of the flexible orifice body is sharp, if the differential pressure between the inlet side and the outlet side is small, the fluid will pass through the valve hole of the flexible orifice body. There was a risk that the flow rate of the fluid would be insufficient.

づるため適正な設定流量の流体が流出口に流通できる。The high-pressure fluid from the inflow port flows through the through hole 35 and the locking body 1.
8, the rubber orifice 15 made of a flexible material such as silicone rubber is bent and deformed toward the outflow 1'' side in response to pressure fluctuations on the inlet side, as shown in FIG. This allows fluid at an appropriately set flow rate to flow to the outlet.

Due to the water hammer phenomenon, the rubber orifice 15 is returned to the inlet side with the fluid, but the locking ring 16 prevents the rubber orifice 15 from reversing and prevents fluctuations in the set flow rate, thereby reducing the fluid pressure on the inlet and outlet sides. Even if the differential pressure of can.
