SEALING STRUCTURE FOR BALL VALVE

摘要

An airtight structure of a ball valve includes a body in which an inclined surface is formed inside; a connection body coupled to the body and in which a locking step is formed at an inner circumferential surface; a ball member inserted into the body to have a side surface come in contact with the inclined surface and opening/closing a fluid passage by operation of a handle; an elastic force applied member in which a side surface comes in contact with the ball member, a fitting groove is formed at the other side, and a pair of groove portions are formed at an outer circumferential surface; and an elastic member in which one side is supported by the locking step and the other side is fitted to the fitting groove to apply elastic force to the elastic force applied member, wherein the ball member, the inclined surface, and the elastic force applied member are continuously in close contact by the elastic force of the elastic member.
