What is the selection standard of pneumatic butterfly valve?
When the excited frequency of the pneumatic butterfly valve is close to the natural frequency, the vibration will be amplified; Only when the excited frequency is greater than the square root of the natural frequency, can the shock absorber have the effect of reducing vibration. The excitation frequency is usually requested to be 2~3 times greater than the natural frequency in order to obtain a good vibration isolation effect.
Detailed methods include: steel spring shock absorber, rubber shock absorber, air spring, rubber shock pad, metal rubber shock absorber and various composite shock absorbers.
Appropriate equipment support shall be provided during operation.
The selection of model and quantity shall not only ensure that it can bear the dynamic load of equipment, but also adhere to small vibration transmission coefficient (ratio of transmission force to interference force).
When designing and applying the shock absorber, the following elements must be considered:
(1) It can provide the required amount of vibration reduction;
(2) Able to bear the load of rules;
(5) Meet the requirements of equipment with shock absorber for the weight and volume of shock absorption.
(4) It has certain damping characteristics;
(3) Can withstand the change of temperature and other environmental conditions (temperature, corrosive fluid, etc.)?

What are the classifications of pneumatic butterfly valves
No matter what kind of machinery or parts there are many classifications, the same is true for pneumatic butterfly valves. So what I want to introduce today is the classification of pneumatic butterfly valves.
1、 Pneumatic butterfly valves are corrugated in shape and can stop stretching like springs. According to the type of corrugation, they can be divided into four types: steel brazing seal, steel welding seal, steel argon arc welding seal and pipe manufacturing seal.
2、 According to the inner pipe diameter: 6mm 8mm 10mm 12mm 14mm 16mm 20mm 25mm 2mm 40mm 50mm 60mm 70mm 80mm 90mm 100mm 125mm 150mm 200mm 250mm 300mm.
3、 Stop classification according to the working pressure value of the hose (kg/cm2): 5,10,15,20,25,30,40,45,50, 55,60,75100120150210250.
4、 Classification according to the use of pneumatic butterfly valve: 1. Recommend all kinds of gases and liquids (corrosive and non corrosive); 2. Maintain the cable to avoid liquid intrusion, mouse bite, etc; 3. For compensation application, Wanma stainless steel pneumatic butterfly valve is used in various industries when there is a difference between upper and lower temperatures or when there is error in device practice
