Labyrinth ultra-low-pressure trickle irrigation emitter

Abstract

The invention discloses a labyrinth ultra-low-pressure trickle irrigation emitter. The trickle irrigation emitter is in a tubular structure with a through hole in the middle. The structure is composed of a labyrinth section, a water outlet section and a connecting section sequentially, wherein the maximum sizes of outer tube diameters of the labyrinth section and the connecting section are the same, a water inlet is arranged at the labyrinth section, a water outlet is arranged at the water outer section, the water inlet and the water outlet are connected through a flower type energy dissipation channel, and the flower type energy dissipation channel is disposed in the tubular wall of the labyrinth section. According to the labyrinth ultra-low-pressure trickle irrigation emitter, a dedicated water pump is not needed, the working pressure is low, the operating coat is low, and the emitter can work normally under the water pressure of the water level of 1.5m; walls of used tubes and pipe fittings are thin, requirements for material strength are not high, the construction cost is low, internal connecting type pipe fittings are adopted, and installation is convenient; the emitter is designed into a plug-and-play mode and easy to dismount for washing, and operating and management costs are low; pipe network laying is flexible and convenient; and users can freely change the spacing of emitters according to different crop spacing between rows and lay pipe networks flexibly.

Description

technical field [0001] The invention relates to drip irrigation equipment, in particular to a labyrinth type ultra-low pressure drip irrigation dripper. Background technique [0002] As an efficient water-saving technology, drip irrigation is mainly used for the irrigation of high-efficiency economic crops. It has a significant effect on promoting the adjustment of my country's agricultural industrial structure and improving crop planting efficiency. However, the development of drip irrigation is also subject to certain constraints, among which the high cost of investment and operation and maintenance is the main reason. As the core component of the drip irrigation system, the structure and performance of the dripper directly affect the irrigation quality, engineering investment and operating costs of the drip irrigation system. At present, the working pressure of the widely used dripper is usually above 10m, and a special water pump is required for water supply and pressur...
