[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example: A double-layer drip irrigation pipe with adjustable water volume in different zones, such as... Figures 1-5 As shown, it includes an inner layer 1, and multiple outer layers 2 are wrapped around the outer wall of the inner layer 1. The multiple outer layers 2 are distributed sequentially along the axial direction of the inner layer 1. The inner layer 1, which is wrapped by the outer layers 2, has multiple first drip irrigation holes 101 on its pipe wall. The first drip irrigation holes 101 connect the inside of the inner layer 1 with the outside. The outer layer 2 has second drip irrigation holes 201 that are radially corresponding to the first drip irrigation holes 101 on its pipe wall. The second drip irrigation holes 201 connect the inside of the outer layer 2 with the outside.

[0024] When using, such as Figure 6 ,Figure 7 As shown, rotating the outer layer 2 makes the first drip irrigation hole 101 and the second drip irrigation hole 201 communicate, and the water inside the inner layer 1 flows out of the outer layer 2 through the first drip irrigation hole 101 and the second drip irrigation hole 201, realizing the drip irrigation effect; reversing the rotation of the outer layer 2 makes the first drip irrigation hole 101 and the second drip irrigation hole 201 not communicate, and the pipe wall of the outer layer 2 shields the first drip irrigation hole 101, so that the water inside the inner layer 1 cannot flow out of the outer layer 2, realizing the effect of closing the drip irrigation.

[0025] By wrapping the outer layer 2 on the outer wall of the inner layer 1, the rotation of the outer layer 2 is used to control the conduction and cutoff between the first drip irrigation hole 101 and the second drip irrigation hole 201, so as to realize the opening and closing adjustment of drip irrigation; at the same time, by adjusting the opening and closing size of the drip irrigation hole between the first drip irrigation hole 101 and the second drip irrigation hole 201, the water quantity is adjusted, so as to realize the accurate control of water quantity. By using the above-mentioned mode, the dripper does not need to be additionally installed after the pipe material is produced and formed, and the pipeline installation construction link is simplified.

[0026] Further, the axial length of the inner layer 1 is greater than the axial length of the outer layer 2, the inner layer 1 is a whole pipe communication, and the outer layer 2 is connected and installed according to different lengths according to the requirement of the use interval, so as to realize the drip irrigation partition control.

[0027] Further, the inner wall of the outer layer 2 is closed and connected with the outer wall of the inner layer 1. By using the above-mentioned setting, the inner layer 1 and the outer layer 2 are sealed at the connection, forming a closed space, that is, when the first drip irrigation hole 101 and the second drip irrigation hole 201 communicate, the water inside the inner layer 1 only flows out of the outer layer 2 through the first drip irrigation hole 101 and the second drip irrigation hole 201, and will not flow out along the gap between the outer wall of the inner layer 1 and the inner wall of the outer layer 2, and when the first drip irrigation hole 101 and the second drip irrigation hole 201 do not communicate, the water inside the inner layer 1 will not flow out along the gap between the outer wall of the inner layer 1 and the inner wall of the outer layer 2.

[0028] As preferred, the closed connection between the inner wall of the inner layer 1 and the outer wall of the outer layer 2 can adopt a sealing element (such as an O-ring) or an interference fit connection, which can rotate the outer layer 2 while ensuring sealing.

[0029] Further, the rotation angle of the outer layer 2 is ±5°, that is, when the first drip irrigation hole 101 and the second drip irrigation hole 201 communicate and the drip irrigation hole is opened to the maximum, the outer layer 2 rotates 5° clockwise or counterclockwise, so that the first drip irrigation hole 101 and the second drip irrigation hole 201 do not communicate, and the pipe wall of the outer layer 2 shields the first drip irrigation hole 101.

[0030] The above merely is preferred implementation manner of the present application, the protection scope of the present application is not only limited to the above examples, and belongs to the technical scheme under the idea of the present application all belongs to the protection scope of the present application. It should be pointed out that, for ordinary skilled person in the art, under the premise of not departing from the principle of the present application, some improvements and decorations, these improvements and decorations should also be considered as the protection scope of the present application.
