摘　　要：旋转阀的常规设计方法需要建立多种模型,影响旋转阀设计研发效率。为此,提出了一种扇形阀口连续波旋转阀参数化优化设计方法,通过特征设计参数尺寸的设定,实现旋转阀模型的参数化,将参数化设定的旋转阀性能关键结构参数和网格尺寸参数进行标注及定义,再经CFX分析计算,实现建模分析一体化。分析结果表明:转子旋转对流道产生节流效果且流场较复杂;流体在通过旋转阀后,除边壁处属于射流外,中间为混乱的紊流状态;转子连续旋转,周期性阻挡钻井液的过程中会产生一层一层的压力波,同时向上、下传递;试验结果与仿真分析结果基本一致,验证了仿真结果的正确性。该优化设计方法为连续波旋转阀的国产化设计奠定了理论基础。The conventional method for designing rotary valve needs to build a variety of models,which affects the efficiency of rotary valve design and development.In this paper,a parameterized optimization design method for rotary valve with quadrant valve port was proposed.By means of setting the size of characteristic design parameters,the parameterization of rotary valve model was realized;the key structural parameters and grid size parameters of rotary valve performance set by parameterization were marked and defined,then,by means of CFX analytical calculation,the integration of modeling and analysis was realized.The analysis shows that the rotation of rotor produces throttling effect on the flow channel and the flow field is complex;after the fluid passes through the rotary valve,except that the edge wall belongs to jet,the middle is in a chaotic turbulent state;the rotor rotates continuously,periodically blocks drilling fluid and produces layer after layer of pressure waves,which are transmitted up and down simultaneously.The experimental verification shows the accuracy of the simulation results.This method lays a theoretical foundation for the localization design of continuous wave rotary valve.
