Damper ball valve Pneumatic ball valve equipment Damper transformer Air compressor Pneumatic ball valve
The ball valve damper is a vibration control installation sensitive to displacement. The pneumatic ball 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.). Ball valve pneumatic ball valve is a kind of pneumatic ball valve with damping, initial force stiffness and ball valve pre tightening to reduce or eliminate other causes caused by medium activity, air pipeline, water hammer (or hammer) and seismic periodic vibration or instantaneous impact damping. It can improve the natural frequency of impact pneumatic ball valve price of vibration pipe suspension ball valve, 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 ball 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 period of the external pipeline or affect the quality, the ball valve preloading with positive initial force shall be selected according to the accurate calculation of the specification of the vibration reducing ball valve. Otherwise, the specification of damping ball valve can be selected according to the nominal diameter of the pipeline.
