Abstract

PURPOSE: To ensure reliable and steady seal of ball valve body for a long time and simplify the assembly of the valve by assembling a seal ring provided with surface pressure adjustment ridges and a back-up ring.
CONSTITUTION: The seal surface 3a of a fluorine resin seal ring 3 and spherical surface of a ball valve body 2 are held in close pressure contact with each other by a back-up ring 6 of an elastic material, ridges 3a of the seal ring 3 and slight elasticity of the seal ring 3 itself to prevent leakage of fluid from the ball valve body 2. The seal ring 3 is in partial contact with ridges 3b of the back-up ring 6, and the depressed portions provided pressure escapement path, so that compression to a sufficient depth can be obtained. The reaction force to the compressing force directly acts upon the seal ring 3. Also, since the back-up ring 6 is compressed to a sufficient depth, a large range of elasticity can be provided.
