- Ball valve is a commonly used type of valve, its opening and closing principle and sealing principle is the ball body rotation and ball and seat sealing surface interaction, first of all, the opening and closing principle of the ball valve is the ball body rotates around the valve stem axis to realize the opening and closing of the medium. When the ball rotates 90 °, the circulation channel of the medium from fully open to fully closed, or from fully closed to fully open. This rotation is simple and reliable, can realize rapid opening and closing, improve work efficiency. Secondly, the sealing principle of the ball valve is that the sealing surface between the ball and the valve seat is sealed by a certain preload. When the ball is rotated to the closed position, the sealing surface and the valve seat closely fit to form a seal. Since the sealing surface and seat are usually made of cemented carbide or other wear-resistant materials, ball valves have excellent sealing and wear-resistant properties.
- In the field of fluid dynamics, the performance characteristics of ball valves are particularly prominent. First of all, the fluid flow characteristics of the ball valve is manifested as a straight line flow, this flow mode makes the ball valve has a very small resistance and pressure loss, so as to ensure the efficient transmission of fluid at the same time, but also reduces the consumption of energy.
- Secondly, we need to pay attention to the ball valve in the opening and closing process, the fluid on its impact and vibration. These shocks and vibrations may have an impact on the normal operation of the valve, so the impact resistance and vibration damping performance of the valve is particularly important. In the design of ball valves, we need to fully consider these factors to ensure that the ball valve in the opening and closing process, can effectively resist the impact of the fluid, at the same time, through a special structural design, reduce the vibration generated, so as to ensure the stable operation of the ball valve.
