The positioning groove 401 is opened on the upper surface of the pipe head 2, and the positioning ring 403 is fixedly installed on the surface of the connecting disk 3. The positioning ring 403 is arranged inside the positioning groove 401, and an internal thread 402 is provided on the inner wall of the positioning groove 401. The positioning ring 40 3 is provided with an external thread 404, which is engaged with the internal thread 402. When it is necessary to replace the connecting disk 3 of different specifications, the staff rotates the connecting disk 3 to disconnect the internal thread 402 from the external thread 404. At this time, the positioning ring 403 can be disconnected from the inside of the positioning groove 401, and the connecting disk 3 can be removed from the upper surface of the pipe head 2. Conversely, the connecting disk 3 can be installed on the upper surface of the pipe head 2 to install connecting disks 3 of different specifications on the upper surface of the pipe head 2, so that the connecting pipe head 1 can be installed on pipes of different specifications.

[0016] like Figure 2 、 3 As shown in , 4, the surface of the tube head 2 is respectively provided with a first sealing groove 5 and a second sealing groove 6, the first sealing groove 5 is arranged on the outside of the positioning groove 401, and the second sealing groove 6 is arranged on the inside of the positioning groove 401, and the upper surface of the connecting plate 3 is fixedly installed with a first sealing ring 7 and a second sealing ring 8, the first sealing ring 7 is arranged on the outside of the positioning ring 403, and the second sealing ring 8 is arranged inside the positioning ring 403, the first sealing ring 7 is arranged inside the first sealing groove 5, and the second sealing ring 8 is arranged inside the second sealing groove 6, and because the first sealing groove 5 and the second sealing groove 6 are both opened on the surface of the tube head 2, the first sealing groove 5 is arranged on the outside of the positioning groove 401, and the second sealing groove 6 is arranged on the inside of the positioning groove 401, the upper surface of the connecting plate 3 is fixedly installed with the first sealing ring 7 and the second sealing ring 8, the first sealing ring 7 is arranged on the outside of the positioning ring 403, and the second sealing ring 8 is arranged inside the positioning ring 403, the first sealing ring 7 is arranged inside the first sealing groove 5, and the second sealing ring 8 is arranged inside the second sealing groove 6, which can perform double sealing when the connecting plate 3 is installed on the upper surface of the tube head 2, and the sealing performance is better.
