Rubber pneumatic butterfly valve ----- pneumatic butterfly valve of fan, pneumatic butterfly valve of water pump, pneumatic butterfly valve of air conditioner
In fact, there are two classifications of rubber shock absorber, one is function classification, the other is appearance classification. The rubber shock absorbers are roughly classified as follows according to their functions:
1. Support various installed rubber shock absorbers in a narrow sense;
2. Rubber buffer for shock absorption;
3. Rubber springs used as mechanical actuating parts;
4. Dynamic shock absorber to eliminate vibration of specific vibration frequency;
5. Rubber couplings are also included in the category of rubber shock absorbers.
Rubber shock absorbers are classified as follows according to their narrow appearance:
1. Compression type: this type is a rubber shock absorber mainly used in the compression direction. The advantage is that the load acceptance force is large, but the elastic coefficient in the tightening direction cannot be too low;
2. Shear type: this type is a rubber shock absorber mainly used in the shear direction. Its load bearing force is small, but it has the advantage that the elastic coefficient can be selected very small;
3. Composite type: it is a rubber shock absorber used in the combined direction of compression and shear, with the middle characteristics of compression and shear;
4. Cylindrical type: This type of rubber damper can be used for vibration reduction in vertical, axial, twisting, prying and other directions. It is similar to the compact rubber alkali vibrator in the vertical direction of the shaft. Its load acceptance force is generally large, but the elastic coefficient cannot be too small.

When installing stainless steel pneumatic butterfly valves, we should pay attention to what kind of stainless steel pneumatic butterfly valves are made of stainless steel bellows with one or more layers of steel wire or steel belt mesh sleeves, and both ends are equipped with connectors or flange heads to escort flexible elements of various media.
Features: corrosion resistance, high temperature resistance, low temperature resistance (- 196 ℃~+420 ℃), light weight, small size, good flexibility.
It is widely used in aviation, aerospace, petroleum, chemical industry, metallurgy, power, paper making, wood, textile, construction, medicine, food, tobacco, transportation and other industries.
1. Recommend corrosive chemical media or organic solvents. (For example: loading and unloading ammonia, acetone, etc.)
2. Escort high-temperature gas, hot oil and other high-temperature media. (e.g. hot steam, heat transfer oil, etc.)
3. Escort low-temperature or ultra-low temperature media. (e.g. liquid nitrogen)
4. Water, steam, oil and other media shall be guaranteed under high temperature environment. (e.g. water steam system and hydraulic system in coking, steelmaking and continuous casting equipment)
5. Pipeline requiring shock absorption or noise elimination.
So what should you pay attention to when installing stainless steel pneumatic butterfly valve? Here is your answer.
① The bending radius shall not be less than 6 times the outer diameter of the hose.
② The spacing between fixed points shall not be greater than lm, and the spacing between pipe clamp and terminal, elbow midpoint should be 300mm.
③ The fixed pipe clamp at the end of the pneumatic butterfly valve connected with the embedded lamp or similar appliance should be installed at lm along the length of the hose from the edge of the lamp and appliance.
