The ball valve is a commonly used valve type, which uses the valve ball to rotate in the valve body to control the flow of the medium. Ball valves have the advantages of simple structure, small size, light weight, and good sealing performance, and are widely used in petroleum, chemical, pharmaceutical, metallurgical and other industrial fields. The working principle of the ball valve is based on the rotation of the valve ball to control the flow of the medium. In the normally closed state of the valve, the ball prevents the passage of fluid by trapping the passage or aperture according to the design. When the valve stem is turned backward at a certain angle, the valve ball rotates along the inner wall of the valve and releases the passage or aperture so that the fluid can pass through smoothly.Due to the reasonable ball design of the ball valve, the flexible valve stem switch, there is no unnecessary conversion and distortion when the fluid passes through, and the fluid viscosity has little influence on the performance of the ball valve, so the valve operates stably during use.
