[0032] A sealing ring 2 is configured to seal the ports of two butted tube bodies 3;

[0033] Preferably, the sealing ring 2 is disposed between two clamping rings 14 and elastically pressed on the port positions of the two butt-jointed pipe bodies 3 to seal the interface positions.

[0034] As an embodiment of the joint assembly, the joint assembly includes two semicircular hoop bodies 1 that can be butted together, and two semicircular clamp rings 14 are provided on the hoop bodies 1; a connecting plate 11 is fixedly provided on both sides of the hoop body 1; and a fixing assembly is further included, and the fixing assembly is configured to fix two opposite connecting plates 11 when the two hoop bodies 1 are butt-fitted together;

[0036] Furthermore, the connecting plate 11 is provided with a through hole, and the fixing assembly includes a column member penetrating through the through holes of two opposite connecting plates 11 and a nut 13 threadedly connected to the column member;

[0037] Optionally, the column member of the utility model is a bolt 12. After the bolt 12 is inserted into the through hole, a tool such as a wrench is used to fix the bolt 12 on one side, and a nut 13 is tightened on the other side.
