Dongfeng electric butterfly valve is widely used in the self-adjusting air suspension of commercial cars, buses, rail vehicles, machinery equipment and building bases. The electric butterfly valve is composed of air and has small internal friction, which will not affect the ability to isolate high-frequency vibration due to the inherent vibration of the butterfly valve itself. In addition, the butterfly valve has no metal to metal contact, so it can sound insulation and sound proof effect is also very good.
Stiffness of butterfly valve: when designing the stiffness of butterfly valve, it can be selected by changing the internal pressure of butterfly valve, and the stiffness is roughly proportional to the internal pressure. Therefore, the stiffness can be selected very low as required. For a butterfly valve with a given size, the stiffness is variable, and it changes with the change of load, so the natural vibration frequency is almost constant under any load, Therefore, it can make the supported system have almost constant performance. The butterfly valve is connected to the additional air chamber, but the natural vibration frequency of the electric butterfly valve device is reduced to 0.5~3Hz. Under the action of any load, the butterfly valve can maintain a low and nearly equal vibration frequency. An orifice is added between the butterfly valve and the additional air chamber. When the spring-loaded load vibrates, the air flows through the orifice and has energy loss, thus playing the role of vibration attenuation. The body structure of the butterfly valve is soft, so it has a comprehensive vibration isolation effect in axial, transverse and rotary directions. The electric butterfly valve is relatively cheap, easy to install and replace, simple to maintain, and does not need frequent maintenance and refueling.
