With the depth of domestic household appliances, light industry, food machinery, packaging machinery, flexible manufacturing systems, industrial robots and other emerging industries and the development of new technology and industrial automation in various industries, the pneumatic technology applications continue to be expanded. New areas of application of pneumatic technology, the performance of the systems, components, volume, weight, reliability, and so the new requirements.
      Pneumatic function pipe joints in pipe joints on additional functional elements, it is used in pneumatic systems can significantly reduce the number of system components, the weight and increase the reliability of the system and reduce the system cost and save energy.
      Pneumatic fittings type: non-ferrous metal fittings. Working principle and characteristics: non-ferrous metals, mainly copper tube and aluminum tube, radial force arising from the use of compression fittings nut tightening card, the card sets and tube deformation simultaneously and stuck pipe from the link and sealing action simple structure, reliable sealing. Applicable gas medium working pressure of less than 1 MPa thin-walled metal pipe connection.
2 cotton braided hose connector. The working principle and characteristics: connector part with metal clamps cotton Hose card in fitting core nut connector core is connected to the connector body. Tensioner role rely on core insert hose clamp the clamping force and the joint core and tube body the two cone mutual clamping force connection sealed. Better process, reliable sealing, demolition compared laborious. Medium pressure less than 1 MPa applicable gas pipeline connection. 3.PU tube nylon tube fittings (1) plug-in. Plastic tube inserted into the elastic head card to the top, and pull the plastic tube, and the tip edge of the head card snaps into the outer surface of the tube pressed against the inclined surface at the radial force of the elastic head and card headgear. Connected and sealed by the chuck and the O-ring. When removing the left side to push the elastic chuck, chuck and card caps tightening tightening slant left, can pull out the tube from the chuck. Reliable sealing, quick disassembly. Applicable to gas medium pressure is less than 1 MPa, nominal diameter less than 10mm plastic tube, nylon tube connection. (2) faster screwed. The installation, the first card condom on the connector body, and then sets the plastic tube, and then rightward Raqqah sets the pressing force by the ferrule and the connector body on the cone of the plastic tube clamping, sealing. When removing the card sets left to push the plastic pipe can be extracted. Sealing is reliable, quick disassembly, and low cost. Applicable gas medium pressure less than 0.8 MPa, the Nominal diameter less than or equal to 8 mm plastic tube connection.
