Material selection of pneumatic joint

The processing material of pneumatic joint is different, the processing accuracy, assembly accuracy, pressure resistance, corrosion resistance will be different.

At present, the material of quick connector on the market is composed of copper and PC. the copper part is threaded to ensure the sealing, and the PC part is connected to the hose. Its wear resistance, sealing performance and elasticity are relatively good. If all of them are made of copper, the quick plug structure connected with the hose is not easy to use and wear-resistant. The important thing is that the bad sealing will reduce the pressure of the air pipe and affect the use.

The quick connector is mainly made of nickel plated copper. The quick connector made of nickel plated copper is better than that of copper. Because it is not only more beautiful, but also has better anti-oxidation and anti-corrosion ability than copper. In addition, its production process is more complex than that of copper, and the cost is also higher.

Rubber joints are divided into loose flange type, fixed flange type and threaded type; According to the structure, it can be divided into five types: single sphere, double sphere, reducer, curved sphere and wind pressure coil. The middle sphere can be equipped with different rubber types according to different use environment and different working conditions,

Rubber pneumatic joint is also called rubber soft joint, rubber flexible joint and rubber shock absorption throat. It is easy to find that its main function is to reduce vibration and noise, reduce the destructive force of vibration and noise on the pipeline, and compensate the thermal expansion and cold contraction caused by temperature change, as well as the lateral displacement at a certain angle
