Abstract

The invention belongs to the technical field of valves, and discloses a ball valve. The ball valve comprises a valve body, a flow channel and a containing space are arranged on the valve body, a valve rod, a supporting ring and an elastic piece are arranged in the containing space, the valve rod is arranged in the containing space, the first end of the valve rod is connected with a ball, a through hole corresponding to the flow channel is formed in the ball, the ball can open or close the flow channel, and the ball is wrapped with a sealing assembly. The sealing assembly is configured to seal the joint of the ball and the valve body, the supporting ring is arranged at the joint of the ball and the flow channel and used for supporting the sealing assembly, the valve rod is sleeved with the elastic piece, one end of the elastic piece is connected with the valve body, the other end of the elastic piece is connected with the sealing assembly, and the elastic piece is configured to press the sealing assembly. Therefore, wear of the sealing assembly is compensated. The ball valve is easy to install and high in sealing stability, the reliability of the ball valve is improved, and the service life of the ball valve is prolonged.

Description

technical field [0001] The invention relates to the technical field of valves, in particular to a ball valve. Background technique [0002] Ball valve is a widely used function that can quickly close the valve. At present, the widely used ball valve sealing measures on the market are achieved by holding the ball valve stem tightly with the sealing cap and pressing the valve body at the same time. The ball valve has a simple structure and is easy to seal. But the problem is that the ball valve is under the alternating cycle of high and low ambient temperature, or under the alternating cycle of high and low temperature of the medium in the valve, which causes the aging and wear of the sealing cap, and the sealing force of the sealing cap holding the ball valve stem is weakened, resulting in leakage. [0003] Therefore, there is an urgent need for a ball valve to solve the problems in the prior art. SUMMARY OF THE INVENTION [0004] The purpose of the present invention is t...
