One side of the inner wall of the plug-in pipe 5 is screwed with one side of a filter cartridge 6, and the other side of the filter cartridge 6 is fixedly connected with a through pipe 7.
[0016] Through the use of flange 2, the connection stability of the connecting pipe 1 and the self-priming pump is facilitated. Through the cooperation of the receiving pipe 3 and the plug-in pipe 5, a socket connection is performed, which is simple and quick to install, and the connection efficiency of the pipe is guaranteed. The pipe can be sealed by the sealing fixing structure 4. At the same time, after long-term use, the pipe can be refilled with sealant 9 to avoid problems such as air leakage and liquid leakage, thereby ensuring the working effect of the self-priming pump. Through the effect of the filter cartridge 6, impurities are prevented from entering the pipe, and the smoothness of the pipe is guaranteed. At the same time, the filter cartridge 6 is screwed for installation, which is convenient for replacement and maintenance, thereby ensuring the use effect of the self-priming pump and avoiding wear on the impeller of the self-priming pump. It is easy to use and has strong practicality. The through-pipe 7 is convenient for increasing the liquid delivery distance.
[0017] The sealing and fixing structure 4 includes a sleeve 41, which is sleeved on the outer wall of the plug-in tube 5. A sealing ring 44 is tightly filled between the sleeve 41 and the plug-in tube 5. The sealing ring 44 is fixedly assembled on the inner wall of the sleeve 41, and the sealing ring 44 is sleeved on the outer wall of the plug-in tube 5. The sleeve 41 is screwed to the outer wall of the receiving pipe 3. A turning handle 43 is fixedly assembled on the outer wall of the sleeve 41. A one-way valve 42 is inserted through the side wall of the sleeve 41. The one-way valve 42 is connected to the inner wall of the sleeve 41. Sealant 9 is filled between the sleeve 41 and the receiving pipe 3 and the plug-in tube 5.
[0018] When the sealing fixing structure 4 is needed, first, as the plug-in tube 5 penetrates into the receiving tube 3, the rotating sleeve 41 is gradually screwed to the outer wall of the receiving tube 3, and the sealing ring 44 is used to ensure the sealing of the screwing process. The turning handle 43 facilitates the rotation of the sleeve 41.
