Damping butterfly valve electric butterfly valve equipment unit electric butterfly valve transformer air compressor electric butterfly valve
The electric butterfly valve is a vibration control installation sensitive to displacement. The electric butterfly valve is mainly used for anti vibration of pipelines and equipment in nuclear power plants, thermal power plants, chemical plants, steel plants, etc. It is often used to control fluid vibration excitation (such as fluid pulsation, two-phase flow, high-speed airflow slight wind vibration, etc.). The electric butterfly valve of butterfly valve is pre tightened by damping, initial force stiffness and butterfly valve to reduce or eliminate other reasons for the formation of the electric butterfly valve of butterfly valve of damping type due to medium activity, air duct, water hammer (or hammer) and seismic periodic vibration or instantaneous impact. It can improve the natural frequency of the price of the electric butterfly valve of impact of butterfly valve suspended by vibrating pipe, The interference caused by the forced vibration frequency of the pipeline can prevent the resonance phenomenon of the pipeline and reduce the additional stress caused by the pipeline vibration. 　　
The specification of the valve butterfly valve depends on the selection of anti vibration force to avoid pipeline vibration. If the vibration force calculated through pipeline dynamic analysis can be based on the rigidity of the pipeline and the external pipeline cycle or affect the quality, the butterfly valve preloading with positive initial force shall be selected according to the accurate calculation of the vibration damping butterfly valve specification. Otherwise, the specification of the damping butterfly valve can be selected according to the nominal diameter of the pipeline.
