Butterfly valve damper control installation and suspension butterfly valve damper assembly
The butterfly valve damper 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. 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 shock absorber is the installation that changes the interference force of the vibration source or the transmission characteristics of the system to reduce vibration. The cylindrical shock absorber of is widely used in the automotive suspension system. It can damp the contraction and extension travel. It is called the two-way interactive electric butterfly valve, and uses new types of shock absorbers, including gas filled shock absorbers and resistance adjustable shock absorbers. The working principle of the bidirectional cylinder shock absorber is discussed. When the stroke is tightened, the wheel is close to the body, the electric butterfly valve is tightened, and the piston moves downward on the electric butterfly 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 partially occupied by the piston rod, so the volume of the upper chamber is smaller than that of the lower chamber. A part of the oil pushes the shrink valve back onto the oil tank. These valves save oil and form the damping force of the compressed suspension. The structure of the electric butterfly valve is a piston rod inserted into the cylinder, which is filled with oil. The throttle valve has a throttle valve on the piston, so that the oil in two parts of the space separated from the piston can supplement each other. Damping force is generated when viscous fluid passes through the orifice. The smaller the orifice, the greater the damping force, the greater the oil viscosity, and the greater the damping force. If the size of the throttle valve is constant, the damping will affect the absorption of the electric butterfly valve when it works very fast. Therefore, set up a disc valve butterfly valve at the outlet hole. When the pressure changes, the valve opens, the orifice opening becomes larger, and the damping is smaller. Since the piston is bidirectional, there are butterfly valves on both sides of the piston, called contraction valves and extension valves.
Introduced the damping effect of the damping butterfly valve damper
What are the characteristics of the damper of the damping butterfly valve? There are three types of data for vibration damper of vibration damper butterfly valve: ordinary cast iron, nodular cast iron and nodular cast iron. After heat treatment, the damper of the damping butterfly valve produced by the three kinds of data after heat treatment is little affected by the climate. The special design structure of the damper of the damping butterfly valve can adjust the different heights according to the practical needs. Moreover, it is small in shape and high in quality. It can be conveniently installed in various machines to achieve the purpose of vibration reduction. The air damping butterfly valve shock absorber has a wide load range, strong compliance with active and passive vibration isolation, and obvious effect. The air damping butterfly valve shock absorber is a universal shock isolation product for vibration isolation and noise reduction, vibration control pollution, environmental maintenance, and ideal damping. The butterfly valve in the shock absorber is subject to heat treatment, and has rust prevention, paint baking and other processes to ensure quality. This kind of shock absorber has obvious effect in eliminating the vibration of mechanical mechanism. Its bottom surface is equipped with anti-skid. The valve butterfly valve shock absorber has advantages in terms of device and safety. The damper of the damping butterfly valve has a strong adaptability to work, and can work normally even when the temperature is 40 degrees below zero or 110 degrees above zero. This is the working state that ordinary electric butterfly valves cannot reach. Both positive and negative vibration isolation, impact and vibration have very significant effects, and effective sound solid barrier. It has achieved ideal results in vibration reduction, noise reduction, vibration pollution conditioning and environmental maintenance.
