The floating ball valve adopts a single inclined elastic sealing ring or a V-shaped groove elastic sealing ring structure. When the medium pressure is too small, the contact area between the sealing ring and the spherical body is small, so there is a large sealing specific pressure to ensure reliable sealing and medium pressure. When the time is large, the contact area between the sealing ring and the sphere is increased, so the sealing ring can be subjected to a large medium thrust without being damaged. Since the sealing ring material such as polytetraethylene has good self-lubricating property and the friction loss with the spherical body is small, the service life of the ball valve is long.
