Damping function of pneumatic butterfly valve with damping spring
(1) Damping helps to reduce the resonance amplitude of mechanical structure, thus preventing the structure from being destroyed due to the vibration stress reaching the limit;
(2) Damping helps the mechanical system recover to a stable state soon after being subjected to transient impact;
(3) Damping helps to reduce sound radiation caused by mechanical vibration and reduce mechanical noise. The noise of many mechanical components, such as the shells of transportation vehicles and saw blades, is mainly caused by vibration. Damping can effectively suppress resonance, thus reducing noise;
(4) It can improve the processing accuracy, measuring accuracy and working accuracy of various machine tools and instruments. All kinds of machines, especially fine machine tools, require high seismic resistance and dynamic stability under dynamic environment, and their dynamic performance can be greatly improved through various damping treatments;
(5) Damping helps reduce the ability of the structure to transmit vibration. In the design of vibration isolation structure of mechanical system, the effect of vibration isolation and damping can be significantly improved by using damping technology reasonably.

Influence of unreasonable installation of stainless steel pneumatic butterfly valve pipeline
In order to play its own role in the pipeline, the stainless steel bellows cannot be separated from its installation, so the correct installation of pneumatic butterfly valve is a necessary step. If there is no reasonable installation, it will lead to its incomplete role, which will also have an impact. Now let's introduce the influence of unreasonable installation of pneumatic butterfly valve.
1. When the stainless steel pneumatic butterfly valve is installed in the opposite direction, it will cause condensate to enter into the corrugated interior and affect the operation. It is assumed that under bad circumstances, it will also cause ice to cause damage to the stainless steel bellows and affect the normal operation.
2. When the stainless steel pneumatic butterfly valve is installed, if it deviates from the center line, it will have shortcomings. If it cannot be used normally, it will also cause leakage. Not only the bellows will be damaged, but also the whole system will be affected.
3. The advantage of the packed stainless steel pneumatic butterfly valve is that the pipe diameter is small. Assuming that the compensation amount is large and the installation position is limited, other compensators cannot be installed. Moreover, the packing must be changed regularly, which will lead to jamming when lateral displacement occurs.
