Abstract

The invention discloses a capillary pressure adjuster and an irrigation system. The pressure adjuster comprises an upstream shell, a downstream shell and a pressure adjusting assembly, wherein the pressure adjusting assembly comprises an adjusting body and a first sleeve connection body; the outer diameter of the adjusting body is gradually reduced form upstream to downstream; a transition sectionof which the inner diameter is gradually reduced from upstream to downstream is arranged in a cavity of the downstream shell; a first flow channel is formed between the adjusting body and the transition section; a second flow channel is formed between a second sleeve connection body in a cylindrical section of the downstream shell and the cylindrical section; the first sleeve connection body andthe second sleeve connection body are connected with each other in a sleeving manner and are provided with sealing pieces; a spring is arranged between the first sleeve connection body and the secondsleeve connection body; and an air channel is formed in a connecting portion between the second sleeve connection body and the cylindrical section. The capillary pressure adjuster is stable in performance and large in conveyance capacity; irrigation uniformity of the irrigation system can be ensured; moreover, the capillary pressure adjuster is simple in structure, small in number of parts and convenient to mount; and the manufacturing cost and using cost are further reduced favorably.

Description

technical field [0001] The invention relates to the technical field of agricultural irrigation equipment, in particular to a large-flow capillary pressure regulator used in agricultural irrigation. The invention also relates to an irrigation system provided with said capillary pressure regulator at the capillary inlet. Background technique [0002] In agricultural irrigation systems, irrigation uniformity is an important indicator to measure the quality of irrigation. When the control area of ​​the system is large, the terrain height difference is large, or the water is used randomly in the irrigation group in the system, in order to ensure the uniformity of the irrigation system, the technical solutions that can be adopted at present are: using pressure compensation drippers, branch pressure regulators, Capillary flow regulator and first frequency conversion equipment. Among them, the first frequency conversion equipment is mainly used to stabilize different situations of...
