Advantages of pneumatic butterfly valve compared with screw ball valve
Compared with the traditional screw ball valve, the pneumatic butterfly valve has many advantages:
1. The stiffness of the pneumatic butterfly valve changes with the load and is independent. The height, load capacity and stiffness of the ball valve are widely selected, which makes the ball valve device have ideal characteristics;
2. The height control valve shall be adopted, and the height of the pneumatic butterfly valve shall be properly controlled according to the use, and the ball valve shall be kept at a certain height when the load changes.
3. The pneumatic 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 rotation, and can also transmit torque;
4. The pneumatic 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 pneumatic butterfly valve. The pneumatic butterfly valve is composed of air and has small internal friction, not because of the inherent vibration of the ball valve itself, which can isolate high-frequency vibration. In addition, the pneumatic butterfly valve has no metal contact, so the sound insulation effect is very good.
