[0003] The existing pipe joint has the following defects in use process:

[0004] 1. In the process of liquid delivery, the connection tightness between pipe joint and pipeline is affected by the impact of liquid on the inner wall of pipe joint.

[0005] 2. Since some liquids contain small particles or impurities, the impurities and small particles in the liquid cooling can easily cause scratches or wear on the inner wall of the pipe joint, which can cause damage to the inner wall of the pipe joint, thereby reducing the service life of the pipe joint.
