Ball valve damper is a vibration control device sensitive to displacement. Ball valve pneumatic 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.). Ball valve pneumatic butterfly valve is to reduce or eliminate other causes caused by medium flow, air pipeline, water hammer (or hammer) and seismic periodic vibration or instantaneous impact damping ball valve pneumatic butterfly valve through damping, initial force stiffness and ball valve pre compression, which can increase the natural frequency of impact pneumatic butterfly valve price of vibration pipe suspension ball 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 ball valve depends on the selection of anti vibration force to prevent pipeline vibration. If the vibration force calculated by pipeline dynamic analysis can be based on the rigidity of the pipeline and the period of the external pipeline or affect the quality, the initial pre pressure of the ball valve should be determined according to the accurate calculation of the specification of the damping ball valve. Otherwise, the specification of the damping ball valve can be selected according to the nominal diameter of the pipe.
When the pneumatic butterfly valve extends, the wheel is far away from the body, and the pneumatic butterfly valve extends. At this time, the piston of the pneumatic 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 shock absorber is a device that can change the interference force of the vibration source or the transmission characteristics of the system to reduce vibration.
