[0027] like Figure 1-5 As shown, the solenoid valve structure in the utility model is similar to the existing solenoid valve structure, such as the solenoid valve that can be connected to pipes of multiple specifications disclosed in the patent with publication number CN218992662U. The main improvement of the utility model is to adapt to the connection of pipes of different sizes and ensure the flow rate of water transported by different pipes. When the valve body 1 needs to be connected to the pipe, the utility model selects a sleeve 41 of corresponding size according to the size of the pipe, and sequentially sleeves the multiple sleeves 41 from large to small, so that the inner wall size of the inner ring 5 of the inner wall of the innermost sleeve 41 corresponds to the outer wall size of the connected pipe. At this time, the multiple sleeves 41 are inserted into the main pipe 2, and the main pipe 2 is connected through the flange 3 is installed at the end of the valve body 1 with the matching bolts, so that the main pipe 2 and the multiple sleeves 41 are connected to the valve body 1, and the positions of the multiple sleeves 41 are adjusted, and the inner ring 5 of the inner wall of the innermost sleeve 41 is sleeved on the outside of the connected pipe to achieve connection.

The inner ring 5 cooperates with the outer ring 6 to limit the outer sliding of the sleeve 41.

[0028] like Figure 4 , 5 As shown, the inner wall of the main pipe 2 and the inner walls of multiple sleeves 41 are fixedly connected to the limiting strip 11, and the outer walls of the outer rings 6 at the ends of the multiple sleeves 41 are provided with limiting holes 12, and the limiting holes 12 are slidably connected to the outer walls of the adjacent limiting strips 11 on the outside; when the sleeve 41 moves, the limiting holes 12 on its outer ring 6 slide on the outer walls of the adjacent limiting strips 11 on the outside, and the limiting strip 11 limits the outer ring 6 through the limiting holes 12, so that the outer ring 6 limits the sleeve 41, and the sleeve 41 does not rotate, thereby improving stability and sealing.

[0029] like Figure 3 , 5 As shown, the number of the limiting strips 11 on the inner wall of the sleeve 41 and the main pipe 2 are four, the four limiting strips 11 are evenly distributed, and the number of the limiting holes 12 on the outer wall of the outer ring 6 is equal to the number of the limiting strips 11; multiple limiting strips 11 cooperate with the limiting holes 12 to limit multiple angles of the outer ring 6, thereby improving the stability and strength of the sleeve 41 and the outer ring 6.

[0031] like Figure 4 , 5 As shown, a plurality of insertion holes 9 are provided on the outer wall of one end of the sleeve 41 away from the valve body 1, and the locking bolt 8 is movably connected with the adjacent inner insertion hole 9; the locking bolt 8 can be inserted into the insertion hole 9 to fix the adjacent inner sleeve 41, and the restriction of the locking bolt 8 by the insertion hole 9 is utilized to improve the strength and stability of the restriction of the sleeve 41.

[0032] like Figure 5 As shown, the inner wall of the inner ring 5 and the outer wall of the outer ring 6 are respectively embedded with a first sealing ring 10 and a second sealing ring 13; the first sealing ring 10 and the second sealing ring 13 can improve the sealing of the overall connection to avoid water leakage.

[0033] like Figure 4 , 5 As shown, the second sealing ring 13 on the outer wall of the outer ring 6 fits along the outer wall of the outer ring 6 and the inner wall of the limiting hole 12, and the second sealing ring 13 slides with the outer wall of the limiting strip 11; the second sealing ring 13 fits with the outer wall of the limiting strip 11, which can further improve the sealing performance.

[0034] The implementation steps in this embodiment are as follows: when the valve body 1 needs to be connected to the pipeline, a sleeve 41 of corresponding size is selected according to the size of the pipeline, and multiple sleeves 41 are sleeved in sequence from large to small, so that the inner wall size of the inner ring 5 of the inner wall of the innermost sleeve 41 corresponds to the outer wall size of the connected pipeline. At this time, multiple sleeves 41 are inserted into the main pipe 2, and the main pipe 2 is installed at the end of the valve body 1 through the flange 3 with bolts, so that the main pipe 2 and multiple sleeves 41 are connected to the valve body 1, and the sleeve 41 is inserted into the inner ring 5 on the outside thereof, and the sleeve 41 cooperates with the outer ring 6 to block one direction through the inner ring 5 through which the sleeve 41 passes. So that it will not slide out from the main pipe 2 or the outer end of the sleeve 41 that is larger than the size of the sleeve 41, adjust the positions of the multiple sleeves 41, make the spacing of the innermost sleeves 41 located at both ends of the valve body 1 adapt to the spacing of the two pipes, and use the locking bolts 8 to lock the multiple sleeves 41, and put the inner ring 5 of the inner wall of the innermost sleeve 41 on the outside of the connected pipe to achieve communication. The pcv pipe can be fixed to the inner ring 5 by hot melting, and the metal pipe can be fixed by the locking bolt 8 at the end of the innermost sleeve 41. By using the sleeve connection of multiple sleeves 41, various specifications of pipes can be connected and the flow rate of water transported by the pipeline can be guaranteed.
