Problems solved by technology
[0006] Although the above-mentioned two kinds of pressure regulators have good pressure regulating effects, they each have different applicable conditions, and there are problems such as complex structure, inconvenient installation, and high cost. Especially the first pressure regulator, except for the spring 6' and sealing parts There are five components in total, and the number of parts is large, and there are three parts of the whole regulator that need to be sealed, and the assembly workload is large.
[0007] On the other hand, in the case of the same outer diameter, the maximum flow capacity of the above two pressure regulators is smaller

Embodiment Construction
[0055] In order to enable those skilled in the art to better understand the solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0056] In this article, terms such as "upper, lower, inner, outer" are established based on the positional relationship shown in the drawings, and the corresponding positional relationship may also change accordingly depending on the drawings. It is understood as an absolute limitation on the scope of protection; moreover, relative terms such as "first" and "second" are only used to distinguish one from another component with the same name, and do not necessarily require or No such actual relationship or order between these components is implied.
[0057] Please refer to image 3 , image 3 A schematic diagram of the overall assembly of a capillary pressure regulator provided by an embodiment of the present invention.

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 index to measure irrigation quality. When the system control area is large, the terrain height difference is large, or the rotation irrigation group in the system uses random water, in order to ensure the irrigation uniformity of the irrigation system, the technical solutions currently available are: use pressure compensation drippers, branch pipe pressure regulators, Capillary flow regulator and the first frequency conversion equipment. Among them, the first frequency conversion equipment is mainly used to stabilize different situations of flow changes; t...
