A tension spring 10 is sleeved on the outer wall of the sliding rod 3, and the two ends of the tension spring 10 are respectively fixedly connected to the self-pressure-relieving connector 1 and the adjusting plate 4, and the tension spring 10 adopts an alloy spring with a high elastic coefficient, and a pressure-relieving pipe 5 is fixedly connected to the adjusting plate 4, and a plurality of pressure-relieving holes 6 are opened on the pressure-relieving pipe 5. A through hole is provided on the side wall of the self-pressure relief joint 1, and the pressure relief pipe 5 matches the through hole. A sealing ring is provided on the inner side of the through hole to ensure the sealing of the pressure relief pipe 5 when it moves relative to the self-pressure relief joint 1; excessive pressure inside the pipeline and the joint will push the pressure relief pipe 5 to move outward relative to the self-pressure relief joint 1. At this time, the adjusting plate 4 will synchronously move relative to the sliding rod 3, so that the tension spring 10 increases its own elastic potential energy due to gradual elongation. When the pressure relief pipe 5 moves to the pressure relief hole 6 located outside the self-pressure relief joint 1, the pressure inside the joint will be released through the pressure relief hole 6 to complete the automatic pressure relief of the joint device. After the pressure relief is completed, the pressure inside the pipeline and the joint tends to a normal level. At this time, the tension spring 10 will pull the adjusting plate 4 through its own elastic potential energy, so that the pressure relief pipe 5 and the adjusting plate 4 begin to automatically reset, thereby realizing automatic and timely pressure relief of the pipeline and the joint, and ensuring the normal use of the pipeline joint device.

[0019] When in use, if the internal pressure of the pipeline and the joint is too large, the internal pressure of the joint will push the pressure relief pipe 5 to move outward relative to the self-pressure relief joint 1.

When the pressure relief pipe 5 moves to the pressure relief hole 6 located outside the self-pressure relief joint 1, the pressure inside the joint will be released through the pressure relief hole 6 to complete the automatic pressure relief of the joint device. After the pressure relief is completed, the internal pressure of the pipeline and the joint tends to a normal level.
