The connection principle and characteristics of pneumatic quick connector

The connection principle of pneumatic quick connector

Under the action of pneumatic air pressure, the annular expansion generated by the inclined surface sealing ring of the pipe joint during the forward movement of the movable sleeve makes the sealing part inside the joint closely fit on the pipe wall, and the sealing part inside the joint is tightly attached to the pipe wall, and the gap between the pipe wall and the joint is A large friction force is formed to prevent the joint from being punched out due to the action of pressure, so as to realize the quick connection of the pipeline. This kind of connection can also be understood as the formation of a tight connection structure on the surface of the pipeline under the action of the vertical component of the expansion force of the sealing ring to realize the complete process of sealing and connection.

Advantages of Pneumatic Quick Connectors

1. Pneumatic drive, high work efficiency, high precision, can be used for automatic integration and production line;

2. No need for fire, can realize non-sparking pipeline connection in the area of ​​flammable and explosive dangerous devices, with high safety;

3. The joint and the pipeline are in the form of mechanical seal, which can realize the connection of the same or different materials, and has good vibration resistance, and does not require repeated reinforcement by external force;

4. There is no need to do complicated preparations such as drying treatment and adding raw material belts before installation. After installation, only tightness and strength tests are required;

5. The installation tools are compact and lightweight, easy to operate, easy to learn, and do not need to be equipped with special equipment professionals;

6. Not affected by climate and working space, as long as personnel can reach the location, the connection operation can be completed;

7. High work efficiency, saving the comprehensive cost of pipeline connection. It is a revolutionary innovation in the field of pipeline connection.
