| Abstract: |
| With the rapid growth of the global population and increasing pressures on freshwater resources, water scarcity has become one of the most pressing challenges worldwide. Agriculture accounts for approximately 70% of global freshwater consumption, making the efficient use of water in agricultural irrigation systems essential for sustainable water management. Irrigation valves, as key components in precision agricultural irrigation systems, critically influence the efficiency and reliability of water delivery through their hydraulic performance. This study presents a comprehensive quantitative review of the hydraulic characteristics and optimization of irrigation valves based on research published from 2005 to 2024, drawing from CNKI and Web of Science (WOS) databases. The review identifies research hotspots and evolving trends over time and systematically examines the evaluation indices used to assess hydraulic performance, including core parameters such as flow capacity, pressure loss, and cavitation, alongside important factors like noise, vibration, and sealing performance. Emphasizing advances in valve design, materials, and control methods, the analysis reveals that topological optimization has significantly enabled lightweight and efficient valve designs, composite coatings have greatly enhanced material durability, and optimized valve-closing strategies have effectively mitigated water hammer risks. The study concludes by outlining promising future directions for the hydraulic optimization of irrigation valves, aiming to provide valuable insights and reference points for ongoing and future research in water-efficient agricultural irrigation technologies. |
