Advantages of electric butterfly valve over screw butterfly valve
Compared with the traditional screw butterfly valve, the electric butterfly valve has many advantages:
1. The rigidity of the electric butterfly valve changes with the load and is independent. The height, load capacity and rigidity of the butterfly valve are widely selected, making the butterfly valve device have ideal characteristics;
2. The height control valve shall be adopted, and the height of the electric butterfly valve shall be properly controlled according to the use, and the butterfly valve shall be kept at a certain height when the load changes.
3. The electric butterfly valve has nonlinear characteristics, and the characteristic curve can be designed into an ideal shape. At the same time, it has comprehensive vibration isolation of axial, radial and rotating, and can also transmit torque;
4. The electric butterfly valve can obtain different bearing capacity by adjusting the internal pressure, so as to adapt to various load requirements;
5. High frequency vibration isolation and sound insulation performance of electric butterfly valve. The electric butterfly valve is composed of air and air, and the internal friction is small, not because the inherent vibration of the butterfly valve itself can isolate high-frequency vibration. In addition, the electric butterfly valve has no metal contact, so the sound insulation effect is very good.
