Connection principle and characteristics of 4mm pneumatic fittings
4mm pneumatic fittings are often used in automated production integration to quickly seal some pipes, holes, etc. as needed for air tightness testing, pressurization testing, and other places.
A. Connection principle of 4mm pneumatic fittings
Under the action of pneumatic pressure, the ring expansion generated by the movable sleeve during the forward movement of the beveled sealing ring of the pipe fitting makes the sealing parts inside the fitting fit closely to the pipe wall, and creates a large friction between the pipe wall and the fitting to prevent the fitting 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 connecting by forming a tight connection structure on the surface of the pipe under the action of the vertical component of the expansion force of the seal.
Second, the advantages of 4mm pneumatic fittings
1、Pneumatic drive, high efficiency, high precision, can be used for automatic integration with the production line.
2、No need to start a fire, can be in the flammable, explosive hazardous device area to achieve non-sparking pipe connection, high safety.
3、The mechanical seal between the joint and the pipeline is in the form of mechanical seal, which can realize the connection of the same or dissimilar materials, and good anti-vibration, without the need for external force to repeat the reinforcement.
4、No need to do complicated preparation work such as drying treatment and adding raw material belt before installation, only tightness and strength test is needed after installation.
5、The installation tools are compact and light, easy to operate, easy to learn and easy to know, no need to equip special equipment professionals.
6、It is not affected by climate and working space, as long as the personnel can reach the location, can complete the connection operation.
7, high efficiency, save the comprehensive cost of pipeline connection. It is a revolutionary innovation in the field of pipeline connection.
