摘要
随着国外海洋油气勘探装备研发技术的封锁,深海电液换向阀的国产化研制成为我国迫切要解决的问题。在对两位三通电液换向阀结构和性能分析的基础上,建立其开启和关闭过程中阀位切换的动态数学模型,对两位三通电液换向阀的动态特性进行仿真分析,研究换向阀开闭过程动态性能。由Simulink仿真结果得到在阀开闭过程中阀芯位移和主阀两端压力的变化规律,证实了所建阀位切换动态数学模型的正确性。
With the abroad blockade on technologies for the offshore oil and gas exploration equipment,domestic development of deep-sea electro-hydraulic directional valve becomes urgent at home. Based on analyzing both structure and performance of the two-position three-way electro-hydraulic directional valve, a dynamic mathematical model for its valve position switching during both opening and closing process was established to simulate and analyze its dynamic characteristics, including the study of the dynamic performance of the valve in the opening and closing process. The changes of spool displacement and pressure at both ends of the main valve in valve opening and closing obtained by Simulink simulation results prove the correctness of the established dynamic mathematical model of valve position switching.
