The connection principle and working principle of Pneumatic Fitting

Pneumatic Fitting is widely used in the automotive industry, new energy battery industry, industrial automation industry, medical equipment industry, air conditioning, refrigeration industry, etc. The quick lock design, simple structure, easy understanding of the principle, and convenient operation. The following is a brief introduction to the connection principle and working principle of Pneumatic Fitting. Here are some answers.

What is the connection principle of Pneumatic Fitting?

Under the action of the pneumatic pressure, the ring expansion generated by the beveled seal of the pipe joint during the forward movement of the movable sleeve makes the sealing parts inside the Pneumatic Fitting fit closely to the pipe wall and creates large friction between the pipe wall and the joint, preventing the joint from being flushed out due to pressure, thus achieving a quick connection of the pipe. This connection can also be understood as a complete process of sealing and joining by forming a tight joint structure on the pipe surface under the vertical component of the expansion force of the seal.

How does Pneumatic Fitting work in seal testing?

Pneumatic Fitting works on the principle that when there is no driving air pressure, the Pneumatic Fitting seal is in its normal state and can be easily inserted or wrapped around the tubing. After insertion to the proper depth, the drive air pressure is applied and the air pressure pushes the metal ring unit inside the main sleeve, which in turn squeezes the front seal, causing the seal to expand and deform to form a sealed contact with the pipe wall of the sealed fitting to achieve a sealed connection. After the sealing tube is filled with testing media, the test begins. Special attention should be paid here to the depth of contact between the joint and the sealing tubing, the greater the depth means the greater the contact area, and the better the sealing effect will be. After the seal test is over, the air pressure inside the sealing tubing should be relieved first, and then the pressure should be relieved to the drive interface, staying for 0.5-1 second. After the pressure relief is completed, the metal ring unit will retreat and release the squeeze on the seal, thus the seal will return to its original state and be out of contact with the pipe wall. The sealing connection is finished and the fitting is gently withdrawn.

The most important thing about Pneumatic Fitting is to ensure that the parts and seals are not damaged and do not fail during operation, but also to facilitate easy and quick connection and disconnection of the connector. The simpler the construction, the easier the operation and the higher the efficiency.
