[0031] Example 1:

[0032] This embodiment provides a municipal water supply pipeline, including two water-passing pipes 1 and a connecting pipe. The connecting pipe is used to connect the two water-passing pipes 1, and the connecting pipe includes:

[0033] Pipe body 2, on which are provided an inlet pipe 21, an outlet pipe 22 and a sewage pipe 23;

[0034] Two connectors 3 are installed on two water pipes 1 respectively. The connectors 3 are detachably installed on the inner wall of the water pipes 1. An elastic snap plate 31 is provided on the inner wall of the connectors 3. A plug plate 32 is provided on the end of the connectors 3 away from the water pipes 1.

[0035] Backflow stopper 4 is rotatably installed inside the connecting pipe body 2 and is used to block the water inlet pipe 21;

[0036] The outer wall of the water inlet pipe 21 and the water outlet pipe 22 is provided with a clamping groove 24 and a plug groove 25, the clamping groove 24 is matched with the elastic clamping plate 31, and the plug groove 25 is matched with the plug plate 32.

[0037] In the technical scheme, when the municipal conveying pipeline is installed, the two connecting pieces 3 are respectively installed and fixed on the two water passing pipelines 1, the inner thread structure is arranged on the inner wall of the pipe opening of the water passing pipeline 1, the connecting piece 3 is in a cylindrical shape, and the outer thread structure matched with the inner thread structure is arranged on the outer wall of the connecting piece 3, so that the connecting piece 3 can be threadedly connected to the pipe opening of the water passing pipeline 1, and the detachable connection between the connecting piece 3 and the water passing pipeline 1 is realized.

[0038] Then, the water inlet pipe 21 and the water outlet pipe 22 on the connecting pipeline are respectively plugged into the two water passing pipelines 1, the clamping groove 24 is arranged on the outer wall of the water inlet pipe 21 and the water outlet pipe 22, in the process of plugging the water inlet pipe 21 and the water outlet pipe 22 into the water passing pipeline 1, the pipe first extrudes the elastic clamping plate 31 on the inner wall of the connecting piece 3, the elastic clamping plate 31 is made of metal material, the elastic clamping plate 31 is deformed when being extruded, after the pipe is inserted into the specified position, the elastic clamping plate 31 returns to the original state and abuts against the inner wall of the clamping groove 24, so that the axial movement of the pipe is limited to realize the connection and fixation. Further, the elastic clamping plate 31 and the clamping groove 24 are a plurality of, the plurality of elastic clamping plates 31 and the plurality of clamping grooves 24 are linearly arranged in the axial direction, and each elastic clamping plate 31 and each clamping groove 24 are matched and clamped one by one. Through the structure design, the clamping stability is effectively enhanced, the connection between the water inlet pipe 21 and the water passing pipeline 1 and the connection between the water outlet pipe 22 and the water passing pipeline 1 are more firm, and the practicability is high.

[0039] The plug plate 32 is arranged on the end of the connecting piece 3 away from the water passing pipeline 1, the plug groove 25 is arranged at the water inlet pipe 21 and the water outlet pipe 22 of the pipe body 2, when the water inlet pipe 21 and the water outlet pipe 22 are plugged into the two water passing pipelines 1, the plug plate 32 and the plug groove 25 are plugged and matched, and the connection stability is enhanced. Further, the magnetic block 26 is arranged in the plug groove 25, and the plug plate 32 is made of metal material and is attracted by the magnetic block 26. Through the attraction between the magnetic block 26 and the plug plate 32, the plug plate 32 and the plug groove 25 are more firmly plugged and matched, and the connection sealing property between the plug plate 32 and the plug groove 25 can be guaranteed. Further, the rubber sealing strip is arranged in the plug groove 25, when the plug plate 32 is plugged into the plug groove 25, the outer wall and the inner wall of the plug plate 32 abut against the rubber sealing strip, so that the connection sealing property of the plug plate 32 and the plug groove 25 is further improved.

[0040] The reverse flow stop piece 4 is installed on the inner wall of the pipe body 2 through the sewage pipe 23, and is located at the communication between the water inlet pipe 21 and the pipe body 2. When water flows into the water inlet pipe 21, the fluid can push the reverse flow stop piece 4 to enter the pipe body 2, and then flow out from the water outlet pipe 22. When reverse flow occurs, water flows into the water outlet pipe 22, which pushes the reverse flow stop piece 4 to further abut against the water inlet pipe 21, thereby blocking the water inlet pipe 21, so as to prevent reverse flow.

[0041] Further, the reverse flow stop piece 4 comprises a fixing seat 41 installed in the pipe body 2, a connecting rod 42 hinged at one end to the fixing seat 41, and a stop plate 43 installed at the other end of the connecting rod 42. A valve seat is further installed in the pipe body 2 and located at the communication between the water inlet pipe 21 and the pipe body 2. The end surface of the stop plate 43 abuts against the valve seat. Through the structure design, when the fluid flows forward, the fluid pushes the stop plate 43 to move and drive the connecting rod 42 to rotate around the hinge, so that the water inlet pipe 21 and the pipe body 2 remain in communication, and the fluid can flow normally. When the fluid flows reversely, the stop plate 43 remains stationary and blocks the communication between the water inlet pipe 21 and the pipe body 2. The reverse flow fluid enters the pipe body 2 and cannot flow into the water inlet pipe 21, thereby achieving the reverse flow prevention effect.

[0042] In summary, by installing the connecting piece 3 with the elastic clamping plate 31 and the plug-in plate 32 on the two water passing pipes 1, the water inlet pipe 21 and the water outlet pipe 22 of the connecting pipe can be connected with the two water passing pipes 1 through the plug-in connection of the connecting piece 3, which is simple and convenient to operate and has high practicability.

[0043] The reverse flow stop piece 4 is arranged at the communication between the pipe body 2 and the water inlet pipe 21. When the fluid flows forward, the reverse flow stop piece 4 is in an open state, and the fluid flows forward. When the fluid flows reversely, the reverse flow stop piece 4 blocks the communication, thereby preventing reverse flow.
