Problems solved by technology

This form of surge valve has been widely promoted and applied in many developed countries in Europe and the United States, but it is difficult to promote in our country. It is also around 4,000 yuan), which is difficult for ordinary farmers to accept; second, it is driven by electricity, and the operating cost is high; third, the structure of the surge valve is too complicated, and it is difficult to use and maintain

Abstract

The invention belongs to the field of field irrigation, and relates to a hydraulic driving surge wave irrigation intermittent valve which comprises a T-shaped three-way valve body, a left corrugated pipe flexible sack, a right corrugated pipe flexible sack, a T-shaped connecting rod, a spring, a valve ball outer connecting rod, a valve ball inner connecting rod, a valve ball and the like. A 'lifting jack'principle is adopted, the relationship among intensity of pressure, area and thrust and spring energy storage are utilized, the purpose of utilizing hydraulic driving to replace power drivingis achieved, the valve has a simple structure and is convenient to use and maintain; and the input and running expense are reduced greatly.

Description

Technical field: [0001] The invention relates to an intermittent valve device for surge irrigation, in particular to a hydraulically driven intermittent valve device for surge irrigation. Background technique: [0002] Surge (surge or intermittent) irrigation technology is an advanced surface irrigation method, which uses a large flow, rapid advance, and intermittent method to release water to the ditch (furrow). Compared with the traditional continuous irrigation method, it can generally save 30% of the water. %, the irrigation efficiency can be increased by 20% to 45%, the uniformity of irrigation can be increased by 10% to 15%, and the work efficiency can be improved by about 30%. [0003] The surge irrigation system is generally composed of a water source, a surge valve, a controller, and a water transmission and distribution pipeline, among which the surge valve and the controller are the core equipment of the entire system. The irrigated area controlled by the first a...
