| 摘要: |
| 【目的】解决现有自动灌溉系统高度依赖电能、通信网络、系统结构复杂等问题,探索将自动灌溉系统中的控制系统与灌溉阀门相结合的方法。【方法】通过设计一种水力驱动的灌溉控制阀,在无电能供给的情况下仅依靠阀芯自重和改变管道内的压力实现阀门启闭,通过改变灌溉首部供水压力远程控制田间灌溉阀门,对阀门开展可行性试验并探明其水力性能参数。【结果】水力驱动灌溉控制阀各结构工作正常,可实现通过改变管道内压力远程控制阀门启闭及换位的目标;当工作压力介于50~140 kPa时,流量介于48.50~74.98 m3/h、水头损失介于3.89~9.60 m,工作压力与流量呈幂函数关系,流量与水头损失呈线性正相关。【结论】水力驱动灌溉控制阀各项参数偏差均小于设计额定偏差,可应用于实际灌溉工程。 |

| 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. |
