The pneumatic ball valve is used to inject compressed air into a sealed container and use the compressibility of the gas to reflect the role of the ball valve. The commonly used pneumatic ball valve device consists of a ball valve body, an additional air chamber and a height controller.
Features of pneumatic ball valve
In the vibration isolation system such as mechanical equipment, the pneumatic ball valve has the following points:
1. In the design, the height, bearing capacity and ball valve constant of the ball valve are mutually independent and can be selected within a wide range.
2. The stiffness of the pneumatic ball valve can be reduced by changing the working pressure of the air and increasing the volume of the additional air chamber. A very soft ball valve can be designed.
3. The stiffness of the pneumatic ball valve changes with the load, so the vibration isolation effect of the system is almost unchanged
4. Through the height control system, the working height of the pneumatic ball valve can be kept certain under any load, which is conducive to engineering application.
