[0007] At least two sealing rings are arranged on the end plate, and the corresponding positioning components are inserted into the sealing rings when being installed into the corresponding pipe holes.

[0008] Further, the inner diameter of the pipe hole is greater than the outer diameter of the pipeline, and there is a gap between the pipeline and the pipe hole when the pipeline is inserted into the pipe hole, and the positioning component is located in the gap, and an outer thread is formed on the outer wall of the two assembled sleeves, and an inner thread is formed on the inner wall of the pipe hole, which is screwingly cooperated with the outer thread.

[0009] Further, a sealing ring in ring shape is arranged on the inner wall of the sealing ring, and a sealing groove corresponding to the sealing ring is formed on the two assembled sleeves in ring shape, and the sealing ring is clamped into the sealing groove when the two assembled sleeves are inserted into the sealing ring.

[0010] Furthermore, it also includes a sealing component. Both assembly sleeves have semi-circular threaded grooves. When the two assembly sleeves are assembled in a ring, the threaded grooves on them are combined in a ring. The sealing component is screwed into the threaded groove to seal the connection between the pipe and the positioning component.

[0011] Furthermore, the sealing assembly includes a sealing ring screwed into the corresponding threaded groove of the assembly sleeve, and a sealing ring is provided on the inner wall of the sealing ring, which contacts the outer wall of the pipe.

[0012] The beneficial effects of this utility model are reflected in:

[0013] In this invention, when one end of the pipe is inside the pipe hole, two assembly sleeves can be spliced ​​together to form a ring and installed into the pipe hole. At this time, the two assembly sleeves clamp the pipe, and the sealing layer on its inner wall contacts the pipe to ensure its sealing effect. After the two assembly sleeves are installed, they will be inserted into the closing ring, thus completing the installation of the end plate and the pipe connection. When disassembling, simply remove the assembly sleeves from the pipe hole, and then the pipe can be pulled out. This method can ensure that the pipe has good installation stability and sealing effect when installed on the end plate, and it is very convenient and quick to disassemble, thus facilitating subsequent maintenance or replacement.

[0022] Please refer to Figure 2 And Figure 3 In an embodiment, positioning assembly 1 includes two assembly sleeves 11 that are annular after splicing, which are detachably arranged in the corresponding pipe hole for pipeline 6 to pass through, and the inner walls of the two assembly sleeves 11 are provided with sealing layers 12, which can be flexible graphite sealing layers, and the sealing layers 12 are in contact with and sealingly cooperate with the pipeline 6; the device further includes at least two closure rings 2, which are arranged on the end plate 5, and when the corresponding positioning assembly 1 is installed into the corresponding pipe hole, it is simultaneously inserted into the closure ring 2.

[0023] In specific implementation, when one end of the pipeline 6 is located inside the pipe hole, the two assembly sleeves 11 can be spliced into a ring and installed into the pipe hole, at this time, the two assembly sleeves 11 clasp the pipeline 6, and the sealing layers 12 on the inner walls thereof are in contact with the pipeline 6 to ensure the sealing effect, and after the installation of the two assembly sleeves 11 is completed, they are inserted into the closure ring 2, so that the installation of the end plate 5 and the pipeline 6 at the connection part is completed, and when disassembling, the assembly sleeve 11 only needs to be disassembled from the pipe hole, and then the pipeline 6 can be pulled out, which can ensure that the pipeline 6 has good installation stability and sealing effect when installed on the end plate 5, and is very convenient and fast when disassembled, thereby facilitating subsequent maintenance or replacement.

[0024] In an embodiment, the inner diameter of the pipe hole is greater than the outer diameter of the pipeline 6, and when the pipeline 6 is inserted into the pipe hole, there is a gap therebetween, and the positioning assembly 1 is located in the gap, the outer walls of the two assembly sleeves 11 are provided with external threads 13, and the inner wall of the pipe hole is provided with internal threads that are screw-connected with the external threads 13.

[0025] In practice, when in the installation state, the two assembly sleeves 11 are screwed to the corresponding internal threads of the pipe hole to ensure that the pipe 6 has good stability. When it is necessary to disassemble the corresponding pipe 6, the assembly sleeve 11 is rotated to gradually leave the pipe hole. After it is completely removed, the gap between the pipe hole and the pipe 6 is exposed.
