摘　　要：割缝阀体是水力割缝系统实现钻割一体化的关键部件。基于实体设计及流体动力学分析软件建立阀芯结构三维模型,对阀芯结构进行优化设计。研究结果表明活动阀芯动作的主动力来自流体对活动阀芯的前端面的压力,活动阀芯的截面为锥面加圆弧面过渡的形状为最优化结构,能够获得较大的沿轴向运动的力,且在曲面处速度波动小,阀芯不易产生振动,更有利于阀芯的移动。通过实验室试验,阀体工作状态良好,实现了预期目标。Cutting seam valve is one of the most important elements of the hydraulic cutting seam system realize drilling and cutting integrative. Based on the entity design as well as the fluid dynamics analysis software, the three-dimensional models of the spool structure were established. The structure of the spool has been optimized. It proved that front surface cooperated by the arc surface and the conical surface can obtain more power, minor velocity fluctuation in the surface, small vibration, more conducive to the spool motion. By laboratory test, the valve works in a good state and achieves the anticipated goal.
