Water and fertilizer integrated liquid fertilizer control valve

Abstract

The invention discloses a water and fertilizer integrated liquid fertilizer control valve. The water and fertilizer integrated liquid fertilizer control valve comprises a conveying pipeline and a valve assembly, wherein the valve assembly comprises a valve body, a rotating disc, a third flange, a fourth flange, a fixing plate, a top plate and a connecting rod, and elimination assemblies symmetrically and fixedly communicate with the two sides of one end of the valve body. According to the water and fertilizer integrated liquid fertilizer control valve, by arranging an elastic ring and a compression piece, the elastic ring has elasticity and is not prone to abrasion, the compression piece extrudes the elastic ring towards the inner side, the elastic ring and a blocking plate can be tightly attached, the sealing performance between the blocking plate and a dredging groove is guaranteed, the control effect of the control valve on fluid is enhanced, after the dredging groove is blocked, the fluid flows into a branch pipe, a first magnetic block and a second magnetic block have the same magnetism, according to the principle that like poles repel and unlike poles attract, when the fluid impacts the side surface of the first magnetic block, the first magnetic block impacts the second magnetic block, and a branch pipe and an eliminating pipe are increased so that the internal water hammer effect can be relieved, a valve shell is prevented from being repeatedly impacted and damaged, and the service life of the control valve is prolonged.

Description

technical field [0001] The invention relates to the technical field of control valves, in particular to a water and fertilizer integrated liquid fertilizer control valve. Background technique [0002] Water and fertilizer integration technology refers to a new agricultural technology that integrates irrigation and fertilization. Water and fertilizer integration is to use the pressure system (or the natural drop of terrain) to combine soluble solid or liquid fertilizers according to the soil nutrient content and the law of fertilizer requirements of crop types and Features: the compounded fertilizer solution and irrigation water are supplied with water and fertilizer through a controllable pipeline system. After the water and fertilizer are mixed together, drip irrigation is formed through the pipeline and drippers, and the root system of the crop is infiltrated evenly, regularly and quantitatively. The main root soil always maintains looseness and suitable water content. The...

Problems solved by technology

[0005] The purpose of the present invention is to provide a water and fertilizer integrated liquid fertilizer control valve to solve the problem that when the existing control valve proposed in the above background technology is in use, when the valve is closed, the fluid in the pipeline will impact the valve due to inertia. , the valve will be damaged for a long time, and at the same time, the reciprocating switch of the valve will cause serious wear and tear at the plug, which will lead to poor sealing of the plug and make the control valve unable to completely block the flow of fluid. A kind of water and fertilizer integrated liquid fertilizer is proposed For the control valve, by setting the elastic ring and the compression part, the elastic ring is elastic and not easy to wear, and the compression part squeezes the elastic ring inward, so that the elastic ring and the blocking plate can be tightly fitted to ensure the sealing plate and the dredging groove The tightness between them enhances the control effect of the control valve on the fluid. When the dredging groove is blocked, the fluid flows into the branch pipe. The first magnetic block and the second magnetic block have the same magnetic properties. The principle of mutual attraction, when the fluid hits the side of the first magnetic block, the first magnetic block hits the second magnetic block, adding branch pipes and eliminating pipes can alleviate the internal water hammer effect, avoid the valve shell from being damaged by repeated impacts, and extend the length of the control valve. service life
