[0014] Optionally, both the first flange and the second flange are provided with connecting screws, and the end face of the diversion pipe is provided with a threaded hole that matches the thread of the connecting screw.

[0015] Compared with the prior art, this utility model has at least the following beneficial effects:

[0016] In the above scheme, the water supply pipe, water outlet pipe, high-pressure water supply pipe, and high-pressure air supply pipe are installed on the diversion pipe. The water outlet pipe is connected to the water supply network, and the water supply pipe is connected to the water source. During normal water supply, the second and third control valves are closed, and the first control valve is open. Water from the water source is delivered to the water supply network through the diversion pipe and water outlet pipe for residential use.

The structure is simple and easy to control and operate.

[0017] In the above scheme, the impeller installed inside the diversion pipe, with the high-pressure water supply pipe and high-pressure air supply pipe distributed on both sides of the impeller, drives the impeller to rotate at high speed when high-pressure water and high-pressure gas are delivered into the diversion pipe. The high-speed rotation of the impeller accelerates the mixing of high-pressure water and high-pressure gas, improves the mixing degree of high-pressure water and high-pressure gas, and enhances the flushing effect on the water supply network. Since the high-pressure water supply pipe and high-pressure air supply pipe are provided with a first pipe head with a gradually increasing diameter at the end facing the diversion pipe, and the outlet pipe is provided with a second pipe head with a gradually increasing diameter at the end facing the diversion pipe, the high-pressure water and high-pressure gas will be depressurized when delivered into the diversion pipe through the high-pressure water supply pipe and high-pressure air supply pipe, which is conducive to the mixing of high-pressure water and high-pressure gas. When the gas-water mixture formed is discharged through the second pipe head and the outlet pipe, it is pressurized again and delivered to the water supply network, which can further improve the flushing effect on the water supply network.

[0032] like Figure 1 and Figure 2As shown in the illustration, an embodiment of this utility model provides a water supply network flushing device, including a diversion pipe 1.

When the water source is connected and water is supplied normally, the second control valve 7 and the third control valve 8 are closed, and the first control valve 6 is open. The water source delivers water to the water supply network through the diversion pipe 1 and the outlet pipe 3 for residential use.

This structure is beneficial for water delivery during normal water supply. The ends of the water supply pipe 2, the water outlet pipe 3, the high-pressure water supply pipe 4, and the high-pressure air supply pipe 5 away from the diversion pipe 1 are all equipped with a third flange 16. The high-pressure water supply pipe 4 and the high-pressure air supply pipe 5 are distributed on both sides of the diversion pipe 1. An impeller 9 is rotatably assembled inside the diversion pipe 1. The impeller 9 is centrally located inside the diversion pipe 1, and the rotation axis of the impeller 9 is perpendicular to the delivery direction of the high-pressure water supply pipe 4 and the high-pressure air supply pipe 5. The high-pressure water supply pipe 4 and the high-pressure air supply pipe 5 are aligned with the two sides of the impeller 9. When high-pressure water and high-pressure gas are delivered into the diversion pipe 1, they can drive the impeller 9 to rotate at high speed. The high-speed rotating impeller 9 can accelerate the mixing of high-pressure water and high-pressure gas, improve the mixing degree of high-pressure water and high-pressure gas, and enhance the flushing effect on the water supply network.

[0034] like Figures 1 to 5As shown, the high-pressure water supply pipe 4 and the high-pressure air supply pipe 5 are provided with a first pipe head 11 at the end facing the branch pipe 1.

The high-speed rotating impeller 9 can accelerate the mixing of high-pressure water and high-pressure gas, improve the mixing degree of high-pressure water and high-pressure gas, and enhance the flushing effect on the water supply network. Furthermore, since the high-pressure water supply pipe 4 and the high-pressure air supply pipe 5 are provided with a first pipe head 11 with a gradually increasing diameter at the end facing the diversion pipe 1, and the outlet pipe 3 is provided with a second pipe head 12 with a gradually increasing diameter at the end facing the diversion pipe 1, when the high-pressure water and high-pressure gas are delivered into the diversion pipe 1 through the high-pressure water supply pipe 4 and the high-pressure air supply pipe 5, the pressure will be reduced, which is conducive to the mixing of high-pressure water and high-pressure gas. When the gas-water mixture formed is discharged through the second pipe head 12, it is pressurized again and delivered to the water supply network, which can further improve the flushing effect on the water supply network.
