摘　　要：基于水压阀的研究现状和本文所进行过的相关研究得出结论 :从摩擦学的角度选择合理“阀芯 阀套”相互适宜的材料配对和设计有利于抑制空化产生的合适的阀口几何结构形式是研制水压阀的关键技术难点。基于这两方面的技术问题 。Based on related study results the conclusion was presented that the key technologies about water hydraulic valves were reasonable selecting materials of spool and sleeve which is compatible each other, and the control cross-section geometry designing of valve orifices which can attenuate the side-effects of cavitation. Aiming at the key technologies mentioned above, some technology resolutions in present was also discussed.
