针对煤矿排水用电动阀门控制复杂、遇突水时易失灵等缺陷,设计了一种能在水下工作的矿用潜水电动液压控制闸阀,介绍了该闸阀的机械结构组成和工作原理;利用功率键合图理论和MAT-LAB软件对矿用潜水电动液压控制闸阀液压缸开启过程的动态性能进行仿真分析,结果显示液压缸开启过程中产生的速度波动值为基准值的4%左右,此速度波动对潜水电动液压控制闸阀的液压系统影响不大。利用Pro/Engineer和FLUENT研究了潜水电动液压控制闸阀在水中全开时阀管路内流场的变化规律,从仿真结果看该闸阀内流场运行参数基本稳定,能满足煤矿井下应急排水的要求。

According to the complicated control of a mine electric valve applied to the mine water drainage and the ineffective when was in water and other defects, a mine submersible electric and hydraulic controlled valve was designed and the mechanical structure composition and working principle of the valve was introduced.A power bond graph theory and MATLAB software was applied to the simulation analysis on the dynamic features of the open process of the hydraulic cylinder applied in t he mine submersible electric and hydraulic control valve.The results showed that the speed fluctuation value occurred in the open process of the hydraulic cylinder was about 4% of the base value and the speed fluctuation would have less influence to the hydraulic system of the mine submersible electric and hydraulic control valve. The Pro/Engineer and FLUENT was applied to study the variation law of the flow field within the valve and pipeline when the mine submersible electric and hydraulic control valve was in water.The simulation results showed that the parameters operated in the flow field of the valve were basically stable, could meet the requirements of the e mergency water drainage in underground mine.
