テーパ状となされているボール弁。 The valve body 7 is provided with a socket 9 having a female thread 8 and an inner diameter that allows the valve body 2 to pass through, and a pipe connection bushing 11 having a male thread 10 is screwed into the socket 9 to form the valve body 1. The bushing tip outer circumferential surface 12 is made smaller in diameter than the male threaded portion to form a movable circular stepped portion 13, and a fixed circular portion is provided on the inner surface of the valve body body 7 facing the movable circular stepped portion 13 at a distance. A circular stepped portion 14 is formed, and an annular hollow portion 16 is formed by both circular stepped portions 13 and 14, the outer circumferential surface 12 of the bushing tip, and the inner surface 15 of the valve body body opposed thereto. A sealing ring 17 having a cross-sectional shape that almost completely fills the inside is arranged, and is connected to the outer circumferential surface 12 of the bushing tip and the movable circular stepped portion 1.
3 is an obtuse angle, the angle between the inner surface 15 of the valve body body and the fixed circular step 14 is a right angle, the cross section of the sealing ring 17 is trapezoidal, and the movable circular step 14 has a trapezoidal cross section. A ball valve in which the stepped portion 13 and the surface of the sealing ring 17 in contact with the stepped portion 13 are both tapered.
