Abstract
PURPOSE: To prevent the bulging-out of a packing and further prevent the leakage by a method wherein a packing at the ball valve type seal ring is made of a metal ring lined with a resilient member.
CONSTITUTION: When an opening and closing operation water pressure for the seal ring 6 is fed either at an closing inlet port 12 or an opening inlet port 13 to move the seal ring 6 in a direction of water flow, the operating water pressure is sealed by a close contact surface between a rubber plate 17 and the seal ring 6 as well as a close contact surface between the water seal ring 14 and the guide planes 7, 8 under a resiliency of the rubber plate 17, the seal ring 6 is moved in a direction of acting pressure of the operating water pressure to enable either an opening or closing operation of the valve body 12. When a valve body 1 is bulged out under a high pressure, an outer circumference of the seal ring 14 keeps a water sealing function in response to a bulged out of the valve body 1 under an existence of the slit 15 of the sealing ring 14 and a resiliency at the margin of the rubber plate 17.
