The electric butterfly valve is a vibration control device 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, wind vibration, etc.). The electric butterfly valve of butterfly valve is to pre compress the butterfly valve through damping, initial force stiffness and butterfly valve to reduce or eliminate other causes caused by media flow, air pipeline, water hammer (or hammer) and seismic periodic vibration or instantaneous impact damping butterfly valve electric butterfly valve, which can improve the natural frequency of the price of the electric butterfly valve of the vibration pipe hanging butterfly valve, The interference caused by the forced vibration frequency of the pipeline can avoid 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 prevent 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 initial force butterfly valve preloading shall be determined according to the accurate calculation of the damping butterfly valve specification. Otherwise, the specification of the damping butterfly valve can be selected according to the nominal diameter of the pipe.
When the electric butterfly valve extends, the wheel is far away from the body, and the electric butterfly valve extends. At this time, the piston of the electric butterfly valve moves upward. The oil pressure in the upper chamber of the piston rises, the circulation valve closes, and the oil in the upper chamber opens the extension valve and enters the lower chamber. The electric butterfly valve is a device that can change the interference force of the vibration source or the transmission characteristics of the system to reduce vibration.
