According to whether the electric butterfly valve can rotate, the valve can be divided into fixed vibration damping and rotary vibration damping. Fixed vibration reduction refers to taking vibration reduction measures for fixed parts, such as electric butterfly valve of engine base; Rotating vibration reduction means that vibration reduction measures are taken for rotating bodies, such as rotor electric butterfly valve, bearing electric butterfly valve, etc. Fixed vibration reduction mainly refers to base vibration reduction, which is widely used. Electric butterfly valve, butterfly valve electric butterfly valve, fluid electric butterfly valve, etc. can be used for base vibration reduction. Different electric butterfly valves are used according to different conditions. Generally, electric butterfly valves are widely used. 　　
It is an ideal damping data, which has damping effect on vibration. It has great linear flexibility, can be stretched to break without losing its elasticity, and can accept alternating stress without fatigue. Like water, it can hardly be compressed. After being pressed, it will only produce elastic deformation, but its volume will not change. When the temperature is lower than - 30 ℃, the elasticity of the electric butterfly valve is significantly reduced, so the electric butterfly valve should not work in severe cold conditions; At the same time, it is not resistant to high temperature, and its working temperature should not exceed 75-80 degrees. The compressive strength of is much greater than the tensile strength.
The stretching length of is generally about 6 times larger than the tightening interval. When being stretched or compressed, their natural vibration frequencies are not the same.
