When in use, the butterfly valve height, bearing capacity and stiffness can be widely selected to achieve its soft butterfly valve performance.
Height of butterfly valve: height control valve can be used to properly control the height of electric butterfly valve according to the use requirements, and maintain a certain height when the load on the spring changes.
Bearing capacity: for electric butterfly valves of the same size, different bearing capacity can be obtained by changing the internal pressure, which is roughly proportional to the internal pressure. This enables the unified electric butterfly valve to adapt to various load requirements.
Stiffness of butterfly valve: when designing the stiffness of electric butterfly valve, it can be selected by changing the internal pressure of the butterfly valve. The stiffness is roughly proportional to the internal pressure. Therefore, the stiffness can be selected very low as required. For an automobile air valve with a given size, the stiffness is variable and 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 function.
1. The inherent vibration frequency of the electric butterfly valve is relatively low. The electric butterfly valve is connected to the additional air chamber, but the inherent vibration frequency of the electric butterfly valve device is reduced to 0.5~3Hz. Under any load, the electric butterfly valve can maintain a low and nearly equal vibration frequency.

2. It can isolate high-frequency vibration and has good noise isolation effect. The electric butterfly valve is composed of air and has small internal friction and will not affect the ability to isolate high-frequency vibration due to the inherent vibration of the butterfly valve itself. In addition, the electric butterfly valve has no metal to metal contact, so its noise isolation and anti noise effect are very good.
