[0026] Reference Figure 1 and Figure 2The quick repair device for leakage of building drainage PE pipe 9 includes two connectors 1, which are in the shape of a circular tube and have a through hole inside. A sealing ring groove 2 is provided on the circumferential side wall of the connector 1, and the sealing ring groove 2 is matched with the PE pipe 9. A sealing ring 3 is embedded in the sealing ring groove 2, and the sealing ring 3 is tightly installed at the bottom of the sealing ring groove 2. When the PE pipe 9 is inserted into the sealing groove, the end of the PE pipe 9 is bonded to the sealing ring 3, and then a sealant is applied between the side wall of the sealing ring groove 2 and the wall of the PE pipe 9 to fix it, thereby improving the sealing of the PE pipe 9 and the connector 1. On the two connectors 1, a first straight pipe 4 is welded to the end of one connector 1 away from the sealing ring groove 2, and a second straight pipe 5 is welded to the end of the other connector 1 away from the sealing ring groove 2, and the second straight pipe 5 is sleeved on the first straight pipe 4 and slides. When it is necessary to connect two sections of PE pipe 9, the PE pipe 9 is installed on the connector 1, the first straight pipe 4 and the second straight pipe 5 are placed opposite to each other, the second straight pipe 5 is sleeved on the first straight pipe 4, and the overlapping length of the second straight pipe 5 and the first straight pipe 4 is adjusted according to the original length of the PE pipe 9 to compensate for the length of the PE pipe 9 cut off so that the total length of the repaired PE pipe 9 is equal to the original length of the PE pipe 9. This method not only has a simple structure and easy operation, but also can be repaired quickly, reducing labor costs and repair time, and improving the efficiency of pipeline leakage repair. In addition, it can be repaired multiple times, which is convenient for later leakage repair and has sustainable utilization.

[0027] Further, refer to Figure 2 The inner diameters of the two connectors 1 are equal, the inner diameter of the first straight pipe 4 is equal to the inner diameter of the connector 1, the inner diameter of the second straight pipe 5 is greater than or equal to the outer diameter of the first straight pipe 4, a guide ring plate 6 is installed between the second straight pipe 5 and the correspondingly connected connector 1, the guide ring plate 6 is installed on the inner wall of the second straight pipe 5, the water flow in the first straight pipe 4 flows into the second straight pipe 5 and is guided into the connector 1 through the guide ring plate 6, thereby improving the smoothness of the water flow through the two connectors 1.

[0028] Furthermore, refer to Figure 2 The cross section of the guide ring plate 6 is triangular, and the angle formed by the inner inclined surface of the guide ring plate 6 and the end surface of the connector 1 away from the sealing ring groove 2 is 45°, which reduces the right angle of the connection inside the second straight pipe 5, thereby improving the smoothness of the water flow from the second straight pipe 5 into the connector 1, and further improving the smoothness of the water flow through the two connectors 1.

[0029] In the preferred embodiment of the present application, refer to Figure 2 and Figure 3The outer circumference of the first straight tube 4 is sleeved with a sealing ring 7, and the second straight tube 5 is sleeved on the outer circumference of the sealing ring 7. When the second straight tube 5 slides on the outer circumference of the first straight tube 4, there is a clearance fit between the second straight tube 5 and the first straight tube 4. After determining the overlap length of the first straight tube 4 and the second straight tube 5, the sealing ring 7 is expanded and installed between the second straight tube 5 and the first straight tube 4, so that there is an interference fit between the second straight tube 5 and the first straight tube 4, thereby improving the sealing between the first straight tube 4 and the second straight tube 5.

[0030] In the preferred embodiment of the present application, refer to Figure 2 , Figure 3 and Figure 4 The outer side of the second straight tube 5 is sleeved with a sealing hose 8, and the two ends of the sealing hose 8 are connected to the connectors 1 on both sides. Specifically, the end surface of the sealing hose 8 and the end surface of the connector 1 away from the sealing ring groove 2 are bonded by a sealant.

By sleeved with the sealing hose 8 on the outer groove of the second straight tube 5, on the one hand, it can prevent external mud and dust from entering the sliding connection between the second straight tube 5 and the first straight tube 4, reduce wear and increase service life; on the other hand, the sealing hose 8 serves as the second seal between the second straight tube 5 and the first straight tube 4, and the sealing between the first straight tube 4 and the second straight tube 5 is further improved through double sealing.

[0031] In the preferred embodiment of the present application, refer to Figure 3 and Figure 4 A plurality of friction grooves 11 are provided on the peripheral side of the connector 1, and the friction grooves 11 are equidistantly distributed along the circumference of the connector 1. The friction grooves 11 can increase the roughness of the surface of the connector 1, increase the friction force of the connector 1, make the connector 1 easier to hold and rotate in the construction environment, facilitate installation, and help improve maintenance efficiency.

[0032] In the preferred embodiment of the present application, refer to Figure 2 , Figure 3 and Figure 4 An arc groove 12 is provided on the inner wall of the connector 1, and the arc groove 12 extends from the end surface of the connector 1 to the inner side of the connector 1.

Then install the sealing ring 7 between the first straight pipe 4 and the second straight pipe 5, and install the sealing hose 8 on the outside of the second straight pipe 5 for double sealing, thereby improving the sealing of the connection between the first straight pipe 4 and the second straight pipe 5. The smoothness of the water flow inside the connector 1 is improved by the arc groove 12 and the guide ring plate 6 on the inner wall of the connector 1.
