摘要
对纯水液压控制阀的研究现状进行了论述。从密封与润滑形式、气蚀抑制措施及材料选择三方面介绍了研制纯水液压控制阀的关键技术 ,就水介质引起的主要问题及其对液压控制阀的影响、采取的主要措施加以具体阐述 ;针对纯水液压伺服阀、纯水液压比例阀和三类典型纯水液压开关阀 ,从工作原理、结构特点、材料选择和实际效果上进行分析。
The paper deals with the development of water hydraulic valve at home and abroad. The key technologies were introduced from the aspect of seal and lubrication structure, cavitation resistance,materials. The primary matter and impacts on configuration were described due to medium transformation, and the prevention measures were expatiated. The working principle, structural characteristics, material selection and results were analyzed for many kinds of water hydraulic valve respectively. The valve developed by Zhejiang University were presented. The development suggestions of water hydraulic valve were put forward.
