Classification and application of industrial electric butterfly valve
The specific methods of industrial valves are: butterfly valve electric butterfly valve, electric butterfly valve, air butterfly valve, valve gasket, seat type electric butterfly valve, metal electric butterfly valve and various composite valve installation.
The electric butterfly valve is an elastic element connecting the equipment and the foundation surface to eliminate and reduce the vibration force transmitted from the equipment to the foundation surface or from the foundation surface to the equipment. It is an elastic support isolated from the equipment and the foundation surface. When the excited frequency is lower than the natural frequency of the mass (equipment) butterfly valve system, the electric butterfly valve cannot play the role of vibration isolation; When the excited frequency is close to the natural frequency,
The vibration will be amplified; As long as the excited frequency is greater than the square root times of the natural frequency, the electric butterfly valve has the effect of vibration reduction. Generally, the excitation frequency is required to be 2~3 times greater than the natural frequency, so as to achieve good vibration isolation effect.
