Classification and Application of Industrial Pneumatic Butterfly Valves
Specific methods for industrial shock absorption include: spring pneumatic butterfly valve, rubber pneumatic butterfly valve, air spring, rubber shock pad, seat pneumatic butterfly valve, metal rubber pneumatic butterfly valve and various composite shock absorption installations.
Pneumatic butterfly valve is an elastic element connecting equipment and foundation surface to eliminate and reduce the vibration force transmitted from equipment to foundation surface or from foundation surface to equipment. It is the elastic support isolated from the equipment and the foundation surface. When the excited frequency is lower than the natural frequency of the mass (equipment) spring system, the pneumatic butterfly valve cannot play the role of vibration isolation; When the excited frequency is close to the natural frequency,
The vibration will be amplified; As long as the excited frequency is greater than the square root times of the natural frequency, the pneumatic butterfly valve has the effect of vibration reduction. Generally, the excitation frequency is required to be 2~3 times greater than the natural frequency, so as to achieve good vibration isolation effect.

Performance analysis of stainless steel pneumatic butterfly valve
The stainless steel pneumatic butterfly valve is a flexible element with one or more layers of steel wire or steel belt net sleeves outside the stainless steel bellows, and two ends are equipped with joint media. Low temperature or ultra-low temperature media, water, steam, oil and other media in high temperature environment, and pipelines requiring vibration reduction or noise elimination, specification: ￠ 4 - ￠ 600 pressure 0.6MPa-25.0MPa Executive specification: GB/T14525-93.
As a flexible pressure resistant pipe fitting, pneumatic butterfly valve is used in the liquid escort system to compensate for the mutual displacement of the connecting end of the pipeline or machine and equipment, absorb the vibration energy, and can play the role of vibration reduction, noise reduction, etc. It has many advantages such as good flexibility, light weight, corrosion resistance, fatigue resistance, and temperature resistance. Recommend corrosive chemical media or organic solvents, high-temperature gas, hot oil and other high-temperature media.
Stainless steel wire braided hose, metal corrugated pipe for fluid escort, stainless steel pump shock absorption hose, stainless steel fire hose, stainless steel corrugated compensator, stainless steel corrugated pipe for gas machinery. The product has the advantages of good flexibility, corrosion resistance, fatigue resistance, temperature resistance, shock absorption and noise reduction, strong sealing, long service life, etc. It is widely used in textile, chemical fiber, printing and dyeing, petroleum, chemical industry, steel, gas, air conditioning, automobile, fire protection, urban water supply, construction, metallurgy and petrochemical industries.
