Abstract

PURPOSE: To prevent deteriorations in sealing capacity and increase in resistance and to extend the life of the valve by combining the valve seat, of which sealing part is tilted downward toward the outer peripheral, with the valve of which sealing surface deformes to be parallel to the sealing surface of the valve seat.
CONSTITUTION: As the valve receives pressure in falling-in direction toward the valve seat port 31 when sealing, the valve 2 outer peripheral part is drawn toward the valve seat port 3. Resisting this force, the valve 2 outer peripheral part is prevented from slipping by the friction with the valve seat 3. In this case, as the force to prevent slipping is the vector sum of frictional force and resisting force of the valve seat 3, slipping force of the valve 2 toward the valve seat port 31 becomes smaller than the existing type, and bending deformation of the valve 2 toward the valve seat port 31 becomes smaller. Therefore, deterioration in sealing capacity caused by reduction in the sealing area and increase in resistance caused by reduction in effective area of the flow passaage can be restrained, and the life of the valve can be extended.
