Ball valve damper is a vibration control device 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, wind vibration, etc.).
Ball valve pneumatic ball 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 by damping, initial force stiffness and ball valve pre compression, which can increase 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 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 ball valve extends, the wheel is far away from the body, and the pneumatic ball valve extends. At this time, the piston of the pneumatic ball 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.
Barrel shock absorber is widely used in automobile suspension system. It can damp the compression and tension stroke. It is called two-way interactive pneumatic ball valve. New types of shock absorber are adopted, including gas filled shock absorber and resistance adjustable shock absorber. The working principle of the bidirectional cylinder shock absorber is expounded. When the stroke is compressed, the wheel is close to the body, the pneumatic ball valve is compressed, and the piston moves downward on the pneumatic ball valve.
The volume of the lower chamber of the piston decreases, the oil pressure rises, and the fluid flows through the chamber above the piston. The upper chamber is a part of the space occupied by the piston rod, so the volume of the upper chamber is smaller than that of the lower chamber. Some of the oil pushes the compression valve back onto the oil tank. These valves save oil and create the damping force of the suspension under compression.
