Anti-blocking pressure compensation water irrigator with uniform outlet flow and self-adjusting function

Abstract

The invention relates to an anti-blocking pressure compensation water irrigator with a uniform outlet flow and a self-adjusting function. The anti-blocking pressure compensation water irrigator comprises a base, a shell, a pressure compensation gasket and an adjusting needle, wherein the shell is buckled on the base; an inner side wall of the shell is glued with an outer side wall of the base; the pressure compensation gasket is connected with the base; a space encircled by the shell and the base is separated into two chambers; the chamber between the pressure compensation gasket and the shell is arranged as a first chamber; the chamber between the pressure compensation gasket and the base is arranged as a second chamber; a water inlet communicated with the first chamber is arranged on the shell; a water outlet communicated with the second chamber is formed on the base; energy-dissipation runners distributed along circumferential direction are arranged on the outer side wall of the base; runner inlets communicated with the first chamber are arranged at one end of the energy-dissipation runners; runner outlets communicated with the second chamber are arranged at the other end of the energy-dissipation runners; the adjusting needle is located in the second chamber; the root part of the adjusting needle is connected with the pressure compensation gasket and the head part extends to the water outlet.

Description

technical field [0001] The invention relates to an irrigator for agricultural irrigation, in particular to an anti-clogging pressure compensation irrigator with uniform outlet flow and self-adjustment. Background technique [0002] my country is facing a severe water shortage problem. Agricultural water takes up 70% of the total water, but its effective utilization rate is only 30%-40%. Water-saving irrigation came into being. Among them, drip irrigation is one of the most promising agricultural water-saving technologies today, and its water utilization rate can be as high as 95%. It is an important technical measure to ensure the sustainable development of agriculture in our country. The pressure compensation emitter is one of the types of emitters widely used in the drip irrigation system. It is a drip irrigation terminal device that can achieve a constant flow of water through the adjustment of the internal pressure compensation gasket within a certain pressure range. It ...

Problems solved by technology

An effective way to solve physical blockage is to increase the size of the inlet and flow channel of the emitter, but this will sacrifice part of the hydraulic performance of the flow channel, and the outflow will increase accordingly, especially for some small flow irrigation crops, increasing the size of the emitter The size of the inlet and flow channel will reduce the water utilization rate, making it difficult to achieve the purpose of water-saving irrigation
