In this study, the time-averaged 3D flow field in an angle stop valve model is numerically simulated with the CFD approach based on the Reynolds-averaged N-S equations (RANS equations) and standard turbulence k ?εmodel.
通过计算该型阀门的关键几何形状和尺寸对湍动能强度等流动特征的影响,对阀门内流道优化得到如下结论:直角截止阀的开度应提高到喉部有效通流直径的一半以上;直角截止阀的内转角应作导流处理;适当减小阀杆直径,可以有效降低阀芯整体的激振力;对阀芯进行支架固定,可以增加阀杆的等效刚度;对喉颈上部的流动分离区,进行导流处理。
