| Abstract: |
| 【Objective】Conventional automatic irrigation systems face challenges such as reliance on electricity, complex communication networks, and intricate system structures. To address these issues, this paper explores the feasibility of integrating the control system and valves into a unified, hydraulically driven irrigation system.【Method】A hydraulically actuated irrigation control valve (HAICV) was designed, which can be opened and closed solely by the self-weight of the valve core and by adjusting the pipeline pressure, without requiring electrical power. The valve core rotates repeatedly under the guidance of a track mechanism, thereby enabling remote control of field irrigation valve by adjusting water pressure at the master valve of the irrigation network. The structure and working principle of the HAICV were described in detail, and its feasibility and hydraulic performance were experimentally evaluated.【Result】All components of the HAICV operated as designed, enabling remote control of opening, closing, and positional switching of the valve solely by varying pipeline pressure. For working pressure in the range of 50-140 kPa, the flow rate varied from 48.50 to 74.98 m3/h, and the head loss ranged from 3.89 to 9.60 m. The relationship between working pressure and flow rate followed a power-law function, while the flow rate and head loss were positively and linearly correlated.【Conclusion】We designed and tested an irrigation control valve. Experimental results showed that all parameter deviations were below the designed nominal values, demonstrating its feasibility for practical applications in irrigation engineering. |
