Description

Technical Field

[0001] The invention relates to the field of agriculture, and in particular to a wave surge irrigation hydraulic control device. Background Art

[0002] Surge flow irrigation is also called surge irrigation or intermittent irrigation. It uses intermittent valves to intermittently supply water to ditches and furrows, generating surges in the ditches and furrows, accelerating the speed of water flow, shortening the time difference between the beginning and the end of the ditches and furrows receiving water, and making the soil evenly moist. Surge flow irrigation technology is a new type of surface irrigation method. It uses a large flow, rapid advancement, and intermittent manner to release water to the ditches and furrows. Compared with the traditional continuous irrigation method, surge irrigation mainly divides the continuous water supply time into several water supply cycles according to the length of the land to be irrigated, and uses intermittent irrigation to introduce water into the field, so that the water flow is quickly advanced to the end of the ditch on the field.

[0003] Surge irrigation system is generally composed of water source, surge valve, controller and water supply and distribution pipeline, among which surge valve and controller are the core equipment of the whole system. Surge valve is mainly used to control water flow to generate surge. After water flow is introduced from the water inlet of surge valve, it is alternately divided to the left and right by the valve located in the middle position. Surge valve automatically switches between two groups of water supply and distribution pipelines through valve automatic steering to realize intermittent alternating water supply process. Common surge valve is not convenient for controlling water flow in water supply pipeline, which may easily cause waste of water resources and is not convenient for irrigation of ditches and furrows.
