[0019] Specifically, a sealing ring 8 is fixedly connected to the inner cavity of the exhaust joint body 9. The sealing ring 8 is in a "W" shape and is made of nitrile rubber.

[0020] In this embodiment, the sealing ring 8 is provided to provide better sealing performance, and the sealing edge can effectively fill the irregular gap between the joint and the exhaust pipe.

[0021] Specifically, both sides of the bottom of the exhaust joint body 9 are fixedly connected with limiting rings 11, the limiting rings 11 are symmetrically arranged, and the material of the release ring 1 is nitrile rubber.

[0022] In this embodiment: the limiting ring 11 is provided to play a sealing role, and is made of high-temperature anti-aging materials and can withstand thermal stress in a high-temperature environment.
