Abstract

PURPOSE:To give a self-aligning ability to a seal ring so as to enhance the water-tightness of the latter by forming a seat metal which is axially inclined in the inner periphery of a valve housing, and by providing a seal ring having a curved part in a peripheral groove formed in the outer periphery of a valve element. CONSTITUTION:A seat metal 1 having its inner peripheral surface 1a which is inclined in the axial direction of a valve housing B is formed in the inner periphery of the valve housing B. A retainer plate 8 is secured to the circumference of one end face side of a valve element A by bolts 9, and a peripheral groove 2 is formed in the valve element A inside of the retainer plate 8. A seal ring 3 having its outer peripheral surface making contact with the seat metal 1 is disposed in the peripheral groove 2, and has its inner periphery formed thereon with a curved part 3b. With this arrangement the seal-ring may be close contact with the seat metal 1, having a self-aligning ability, thereby it is possible to enhance the water-tightness.
