What are the advantages and disadvantages of electric butterfly valve?
Air is a special electric butterfly valve, which is different from the ordinary electric butterfly valve. It is mainly completed with compressed air. This electric butterfly valve has a common advantage. The electric butterfly valve used in many mechanical equipment must use it to really reduce vibration.
Advantages of electric butterfly valve:
1. Through the height control valve, the working height of the electric butterfly valve can be kept constant under any load, and the butterfly valve can also have different heights under the same load. Therefore, it is conducive to meeting the requirements of multiple structures.
2. The electric butterfly valve has nonlinear characteristics, and its characteristic line can be designed as an ideal curve according to the demand.
3. The rigidity of the electric butterfly valve changes with the load, so the natural vibration frequency is constant under any load, which makes the butterfly valve device have almost constant performance.
4. The rigidity of the electric 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 electric 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 electric butterfly valve body and the additional air chamber, which can play a damping role. If the aperture is properly selected, the electric butterfly valve may not be set.
