[0003] However, in the above-mentioned existing water supply pipe, the first reinforcement line and the second reinforcement line can increase the circumferential pressure-bearing strength of the pipe body, and the third reinforcement line can increase the axial tensile strength of the pipe body. At the same time, a mesh can be formed among the first reinforcement line, the second reinforcement line and the third reinforcement line. The first inner layer and the first outer layer can be hot-melt connected together through the mesh, thereby improving the connection strength among the first outer layer, the reinforcement layer and the first inner layer. The device lacks a device for regulating the pipeline flow and cannot regulate the flow. It also needs to be used with a valve in daily use, which increases the cost of use.

DETAILED DESCRIPTION

[0019] The following is a further detailed description of the implementation of the present utility model in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present utility model, but cannot be used to limit the scope of the present utility model.

[0020] refer to Figure 1-3 The utility model provides a technical solution: it includes a PE water supply pipe body 1, both ends of the PE water supply pipe body 1 are fixedly connected with a first sealing ring 3, the surface of the PE water supply pipe body 1 is fixedly connected with a mounting seat 4, the upper end surface of the mounting seat 4 is sealed with a cover plate 5, the cover plate 5 and the mounting seat 4 are threadedly connected with bolts, a threaded sleeve 7 is rotatably connected in the mounting seat 4, by setting the threaded sleeve 7, the threaded sleeve 7 can drive the threaded rod 11 to move upward or downward when rotating, the threaded sleeve 7 is threadedly connected with the threaded rod 11, the bottom end of the threaded rod 11 is rotatably connected with a connecting block 14, the side of the connecting block 14 is rotatably connected with a connecting plate 13, one side of the connecting plate 13 is rotatably connected with a water baffle 8, a stop block 9 is fixedly connected in the PE water supply pipe body 1, the side of the stop block 9 is fixedly connected with a limiting rod 12, and the water baffle 8 is slidably connected to the surface of the limiting rod 12.

[0021] Among them, the surface of the PE water supply pipe body 1 is slidably connected with a connecting sleeve 2. By setting the connecting sleeve 2, the connecting sleeve 2 can install the PE water supply pipe body 1 on the pipeline, and the inner wall of the connecting sleeve 2 is provided with a thread.

[0022] Among them, the top end of the threaded sleeve 7 passes through the upper end surface of the cover plate 5 and is fixedly connected with a handle 6. By setting the handle 6, the staff can drive the threaded sleeve 7 to rotate through the handle 6, and the bottom end of the threaded sleeve 7 passes through the inner wall of the PE water supply pipe body 1.

[0023] Among them, a second sealing ring 10 is fixedly connected to the side of the water baffle 8. By setting the second sealing ring 10, the second sealing ring 10 can ensure that there will be no water leakage when the pipeline is closed. The side of the second sealing ring 10 is sealed and connected to the side of the block 9.

[0024] The diameter of the water baffle plate 8 is 4 cm smaller than the inner diameter of the PE water supply pipe body 1, and the number of the connecting plates 13 is set to four.

[0025] The inner diameter of the connecting sleeve 2 matches the diameter of the PE water supply pipe body 1 , and the size of the cover plate 5 matches the size of the mounting seat 4 .

[0026] The working principle of the utility model is as follows: first, the staff connects the PE water supply pipe body 1 with the pipe with threads through the connecting sleeve 2, and the first sealing ring 3 can ensure the sealing of the PE water supply pipe body 1 when the pipe is connected. Then, the staff can rotate the threaded sleeve 7 clockwise through the handle 6, and the threaded sleeve 7 can drive the threaded rod 11 to move downward when it rotates. The threaded rod 11 drives the connecting block 14 to move downward, and the connecting block 14 can push the water baffle 8 to move oppositely through the connecting plate 13, so that a gap can appear between the water baffle 8 and the stop block 9. At this time, water can flow out through the gap. When it is necessary to close the pipeline, the staff can rotate the threaded sleeve 7 counterclockwise through the handle 6, and the threaded sleeve 7 drives the connecting block 14 to move upward through the threaded rod 11. The connecting block 14 pulls the water baffle 8 to move relatively through the connecting plate 13, and makes the second sealing ring 10 abut against the side of the stop block 9, so that the pipeline can be closed. The second sealing ring 10 can ensure the tightness when closing, and no leakage will occur.
