The electric butterfly valve is used to inject compressed air into a sealed container and use the compressibility of the gas to reflect the function of the butterfly valve. The commonly used electric butterfly valve device consists of butterfly valve body, additional air chamber and height controller.
Features of electric butterfly valve
In the vibration isolation system such as mechanical equipment, the electric butterfly valve has the following points:
1. During design, the height, bearing capacity, butterfly valve constant, etc. of the butterfly valve are mutually independent and can be selected within a wide range.
2. The rigidity of the electric butterfly valve can be reduced by changing the working pressure of the air and increasing the volume of the additional air chamber, so that a very soft butterfly valve can be designed.
3. The rigidity of the electric butterfly 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 electric butterfly valve is kept constant under any load, which is conducive to engineering applications.
