Detailed Description

The technical solution of the present invention is further described below, but the scope of the claimed invention is not limited to the described.

As shown in fig. 1 to 4, a pipe joint, including connecting plate 1 and connecting pipe 2, processing has through-hole 11 on connecting plate 1, connecting pipe 2 welds on connecting plate 1, and through-hole 11 is located the inboard of connecting pipe 2. When in use, the through hole 11 is located at the center of the connecting plate 1, and the diameter of the through hole 11 is consistent with the inner diameter of the connecting pipe 2.

An annular groove 10 is formed on the connecting plate 1 at the outer side of the through hole 11.

A sealing tape is bonded in the annular groove 10. The sealing tape is a sponge sealing tape.

A sealing groove 21 is machined on the inner wall of the connecting pipe 2 along the circumferential direction.

And a sealing ring is arranged in the sealing groove 21. The sealing ring is a rubber sealing ring.
