Problems solved by technology

[0003] Most of the existing drip irrigation pipes and drip irrigation belts in China have complex labyrinth flow channels and small open outlets, which has brought about the difficult problem of clogging of drip irrigation products worldwide.
Impurities, microorganisms and chemical minerals in irrigation water can cause blockages in this labyrinth flow channel that cannot be controlled and cleaned, which will eventually affect the service life of irrigation equipment, especially when the head is suddenly decompressed every time an irrigation is over. Under the action of negative pressure, the sediment at the water outlet will be sucked back into the drip irrigation pipe (belt)
Therefore these drip irrigation equipment cannot be used for subsurface irrigation

Embodiment Construction

[0019] A pressure-compensated drip irrigation belt, the drip irrigation belt is a double-layer structure closed on both sides in the area where the flow channel and the water inlet and outlet are set, and the flow channel is pre-formed before welding the double-layer pipe wall. As shown in Figure 1, the hook groove flow channel of the drip irrigation tape is set on the outer layer; as shown in Figure 5, the hook groove flow channel of the drip irrigation tape is set on the inner layer. Both forms have an arc-shaped hook groove-shaped flow channel 2 running through the belt body in the belt body 1. This flow channel deforms under the change of water pressure in the pipe, and this deformation affects the cross-sectional area of ​​the flow channel. The water output at different pressures can be automatically adjusted to achieve uniform irrigation. Several water inlets 3 and water outlets 4 are arranged staggeredly on the belt body, so that each water outlet on the drip irrigation...

Abstract

Disclosed is a pressure-compensated drip irrigation belt which includes a belt body, the irrigation belt is characterized in that, the belt body is provided with a groove shape flow passage penetrating the belt body, a plurality of water intakes and water outlets are arranged alternatively on the belt body, wherein the water outlet is provided with a structure of tongue cover which can fit tightly with the water outlet.

Description

[0001] Field: [0002] The invention belongs to irrigation equipment, in particular to a pressure-compensated drip irrigation belt. Background technique: [0003] Most of the existing domestic drip irrigation pipes and drip irrigation belts have complex labyrinth flow channels and tiny open water outlets, which has brought about a worldwide clogging problem of drip irrigation products that is difficult to solve. Impurities, microorganisms and chemical minerals in irrigation water can cause blockages in this labyrinth flow channel that cannot be controlled and cleaned, and ultimately affect the service life of irrigation equipment. Under the action of negative pressure, the sediment at the water outlet will be sucked back into the drip irrigation pipe (belt). Therefore these drip irrigation devices cannot be used for subsurface irrigation. Invention content: [0004] The purpose of the present invention is to overcome the shortcomings of the above-mentioned prior art and pr...
