Abstract
PURPOSE:To prevent the sealing defect by forming the sealing surface of a poppet-shaped valve part for closing a valve seat into a spherical surface having the axis center of a valve rod as center. CONSTITUTION:An input port 2, output port 3, and a discharge port 4 are formed on a valve body 1. Valve seats 6 and 6 are installed oppositely in a valve chamber 5 communicating to the ports 2, 3, and 4. A valve part 22 having valve shafts 23 and 23 is accommodated into the valve chamber 5. The sealing surface 24 of the valve part 22 is formed into spherical surface having the axis centers of the valve rods 23 and 23 as center. Therefore, even if the valve rods 23 and 23 tilt, the sealing surface always seals the valve seat, and the generation of sealing defect is prevented. Further, the need of applying the sealing with an elastic material onto the sealing surface is avoided.
