The first sealing column and the second sealing column are slidingly arranged on the first mounting tube and the second mounting tube through the first moving assembly and the second moving assembly respectively. The first sealing column and the second sealing column are pressed against the first sealing ring and the second sealing ring under the action of the first moving assembly and the second moving assembly, so that when the first mounting tube and the second mounting tube are separated, the first sealing column and the second sealing column respectively cooperate with the first sealing ring and the second sealing ring to block the openings of the first mounting tube and the second mounting tube. The medium in the pipeline will not flow out from the first mounting tube or the second mounting tube, so that when the joint is connected to the pipeline, there is no need to close the main valve to stop the flow of the medium in the pipeline. Insert the second mounting tube into the slot of the first mounting tube, and then limit the second mounting tube by the limiting assembly. After the first mounting tube and the second mounting tube are connected, the first sealing column and the second sealing column are removed by the first moving assembly and the second moving assembly, thereby completing the connection work between the right-angle tube body and the pipeline, which is quick and efficient and will not interfere with the production work of other pipelines.

One end of the first moving spring 42 is fixedly connected to the surface of the first bottom ring 41, and the other end of the first moving spring 42 is fixedly connected to the first sealing column 26. The first sealing column 26 is pressed against the first sealing ring 24 under the action of the first moving spring 42. The first moving rod 43 is installed on the second mounting tube 22 through the second moving assembly 29. When the second mounting tube 22 is plugged into the slot 11 on the first mounting tube 21, the first moving rod 43 is pressed against the first sealing column 26 and drives the first sealing column 26 to compress the first moving spring 42.

[0054] Reference Figure 3 and Figure 5 The second moving assembly 29 includes a second bottom ring 51, a second moving spring 52 and a second moving block 53.

[0055] Reference Figure 3 and Figure 4 When the first mounting tube 21 is separated from the second mounting tube 22 , the first sealing column 26 is pressed against the first sealing ring 24 under the action of the first moving spring 42 , thereby sealing the opening of the first mounting tube 21 .

[0056] Reference Figure 3 and Figure 5 When the first mounting tube 21 is separated from the second mounting tube 22 , the second sealing column 27 is pressed against the second sealing ring 25 under the action of the second moving spring 52 , thereby sealing the opening of the second mounting tube 22 .

[0057] Reference Figure 4 and Figure 5When the first mounting tube 21 and the second mounting tube 22 are connected, since the elastic coefficient of the second moving spring 52 is greater than the elastic coefficient of the first moving spring 42, the second sealing column 27 first drives the first sealing column 26 to separate from the first sealing ring 24 through the first moving rod 43, and after the first sealing column 26 separates from the first sealing ring 24, it drives the second moving block 53 to contact the first bottom ring 41, and after the second moving block 53 contacts the first bottom ring 41, the position of the first sealing column 26 is fixed. After the position of the first sealing column 26 is fixed, since the second mounting tube 22 continues to move, the first moving rod 43 in turn drives the second sealing column 27 to compress the second moving spring 52 to move, and the second sealing column 27 compresses the second moving spring 52 to move so that the second sealing column 27 separates from the second sealing ring 25, thereby connecting the interior of the second mounting tube 22 with the opening, which is convenient for the transportation of the medium.

[0058] Reference Figure 3 and Figure 5 An inner tube ring 13 is fixedly installed on the inner wall of the second mounting tube 22.

The first sealing column 26 and the second sealing column 27 are pressed against the first sealing ring 24 and the second sealing ring 25 under the action of the first moving assembly 28 and the second moving assembly 29, so that when the first mounting tube 21 and the second mounting tube 22 are separated, the first sealing column 26 and the second sealing column 27 cooperate with the first sealing ring 24 and the second sealing ring 25 to block the openings of the first mounting tube 21 and the second mounting tube 22 respectively. The medium in the pipeline will not flow out from the first mounting tube 21 or the second mounting tube 22, so that when the joint is connected to the pipeline, there is no need to close the main valve to stop the flow of the medium in the pipeline. It is only necessary to insert the second mounting tube 22 into the slot 11 of the first mounting tube 21, and then limit the second mounting tube 22 by the limiting assembly 23. When the first mounting tube 21 and the second mounting tube 22 are connected, the first sealing column 26 and the second sealing column 27 are moved away by compressing the first movable spring 42 and the second movable spring 52, thereby completing the connection work between the right-angle tube body 1 and the pipeline, which is quick and efficient and will not interfere with the production work of other pipelines.

[0061] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
