Description

Ball valve ball body with good sealing performance

Technical Field

The utility model relates to the technical field of ball valve balls, in particular to a ball valve ball with good sealing performance.

Background

And the opening and closing piece (ball body) is driven by the valve rod and rotates around the axis of the ball valve. The device can also be used for regulating and controlling fluid, wherein the hard seal V-shaped ball valve has strong shearing force between the V-shaped ball core and the metal valve seat of the hard alloy for surfacing, and is particularly suitable for mediums containing fibers, tiny solid particles and the like. The multi-way ball valve can flexibly control the confluence, the diversion and the flow direction switching of the medium on the pipeline, and simultaneously can close any channel to connect the other two channels. The valve should be installed generally horizontally in the pipeline. In China, the ball valve is widely applied to industries such as petroleum refining, long-distance pipeline, chemical industry, papermaking, pharmacy, water conservancy, electric power, municipal administration, steel and the like, and plays a role in national economy.

After the common ball valve ball body is connected with a pipeline, a flange connecting bolt is required to be locked by a specified torque in a crossing way, meanwhile, a ball valve opening and closing piece is driven by a valve rod and rotates around the axis of the ball valve, the ball valve ball body is used as one of important component parts of the ball valve, and the quality of the ball body often influences the integral use effect of the ball valve, so that the common ball valve ball body structure and the use mode are adopted. The patent number CN217056415U is a fixed ball valve sphere with good sealing performance, and provides the problem that the sealing effect is not ideal in the actual use process of the existing fixed ball valve sphere. Meanwhile, through the cooperation of the sealing ring, the sealing groove and the sealing transition part, the ball valve is sealed in multiple stages, the lifting sleeve is arranged on the valve rod to be matched with the positioning column, after the valve rod is rotated to close the ball valve, the positioning column can avoid effectively avoiding that foreign objects touch the valve rod to cause the ball to loosen, the sealing effect of the ball is affected, and the problem that the sealing effect of the ball of the existing fixed ball valve is poor is solved. When the ball body of the fixed ball valve is closed, media on two sides of the pipeline cannot flow through the valve, certain pressure accumulation can be generated, and as the valve rod and the ball body of the ball valve are connected through the grooves and the protrusions, the ball valve can be conveniently detached and installed, but the connection stability is not ideal, so that the valve rod and the ball body are separated, and the ball body of the ball valve with good sealing performance is provided.
