Pneumatic butterfly valve What are the advantages and disadvantages of pneumatic butterfly valve?
Air is a special shock absorber, which is different from the ordinary ball valve shock absorber. It is mainly completed by compressed air. This kind of shock absorber has a common advantage. It must be used in many mechanical equipment in order to really reduce the vibration.
Advantages of pneumatic butterfly valve damper:
1. Through the height control valve, the working height of the pneumatic butterfly valve can be kept constant under any load, and the ball valve can also have different heights under the same load. Therefore, it is conducive to meeting the requirements of multiple structures.
2. The pneumatic butterfly valve has nonlinear characteristics, and its characteristic line can be designed as an ideal curve according to requirements.
3. The stiffness of the pneumatic butterfly valve changes with the load, so the natural vibration frequency is constant under any load, which makes the ball valve device have almost constant performance.
4. The stiffness of the pneumatic butterfly valve can be stopped by changing the volume of the additional air chamber according to the demand, and the selection can be very low.
5. The same pneumatic butterfly valve can bear axial and radial loads at the same time, and can also transmit torque. Through the adjustment of internal pressure, different bearing abilities can be obtained, so it can meet the needs of multiple loads.
6. High frequency vibration absorption and sound insulation are good,
7. An orifice is set between the pneumatic butterfly valve body and the additional air chamber, which can play a damping role. If the aperture is properly selected, the pneumatic butterfly valve may not be set.
