[0020] The detailed connection means are well-known in the art. The following mainly introduces the working principle and process. The specific work is as follows.

[0021] When in use, the liquid in the tube body 1 will flow normally through the inner cavity of the connecting tube 2, the sealing sleeve 7 and the plug valve body 6; when the plug valve body 6 needs to be maintained and repaired, the sealing sleeve 7 is first rotated to gradually move the two sealing sleeves 7 away from the outer wall of the connecting tube 2 and move them all to the outer wall of the plug valve body 6. At this time, the connecting tube 2 and the plug valve body 6 are disconnected from each other, and the handle 13 is pulled downward. The handle 13 will drive the support rod 12, the base 10 and the positioning block 11 to move downward together. In this process, the base 10 will squeeze the spring 9. When the positioning block 11 is completely moved out of the inner cavity of the positioning hole 5, the turntable 4 and the connecting seat 3, there is no obstruction, the staff can directly rotate the plug valve body 6 to a vertical state, and a "cross" is formed between the plug valve body 6 and the connecting pipe 2. At this time, the exposed sides and the interior of the plug valve body 6 can be maintained and repaired; the device adopts a rotating method, and can adjust the position angle of the plug valve body 6 without disassembling the plug valve body 6, so as to perform daily maintenance and repair on its interface or interior. Compared with the traditional maintenance method, it is not only simple and convenient to operate, saves time and effort, but also greatly improves the overall work efficiency, is easy to use, flexible to use, has strong practicality, and is suitable for promotion.
