Double diaphragm steady flow anti-drip valve

Abstract

The invention discloses a double-diaphragm flow-stabilizing and anti-dripping valve and provides a valve body structure design integrating a flow-stabilizing diaphragm and an anti-dripping diaphragm. Effects that the flow is adjusted to be stable during pressure change and a valve body is opened under the relatively high pressure to guarantee atomization and avoidance of water dripping can be realized simultaneously, besides, the valve is novel in structure design, easy to produce, convenient to assemble, low in cost and long in service life, various flow specifications can be designed, and the valve is applicable to various spray heads, has the higher economic value and social value and is particularly suitable for popularization and use in micro-spraying irrigation systems.

Description

technical field [0001] The invention relates to the technical field of micro-water irrigation, in particular to a steady-flow anti-drip valve device matched with a micro-sprinkler. Background technique [0002] In recent years, because micro-irrigation has many advantages such as water saving, high irrigation uniformity, labor saving, fertilizer saving, and production increase, it has developed rapidly and has been widely used. It has become an important technical means in agricultural production. At present, the national micro-irrigation application area It has reached more than 30 million mu. [0003] Micro-irrigation mainly includes two forms of drip irrigation and micro-sprinkler irrigation. Micro-sprinkler irrigation is a form of irrigation that uses refracting or rotating micro-sprinklers to spray low-pressure water or chemicals with micro-flow and low pressure on branches and leaves or on the ground through a pipeline system. The working pressure of micro-sprinkler ...

AI Technical Summary

Problems solved by technology

"Although this kind of anti-drip valve can realize the function of constant pressure and anti-drip, the structure is relatively complicated, especially the use of springs as elastic elements, the cost is high, and it cannot be used in large areas on micro-sprinklers in agricultural irrigation.

[0010] To sum up, the existing micro-sprinklers have the problems of not being able to form mist at low pressure and uneven flow when the working pressure is inconsistent. However, the products currently used for steady flow and anti-drip of micro-irrigation micro-sprinklers mainly have complex structures and low cost. High, unable to achieve steady flow and anti-drip functions at the same time
