中文摘要:
      目的 滑阀结构对阀流场有直接影响,为提高滑阀性能,对不同阀芯结构阀流场进行分析。方法 采用U型、三角型和无节流槽3种阀芯结构,利用ADINA软件流固耦合模块,对3种阀芯的滑阀流场情况进行分析计算,研究阀流道内流体流速和压力分布情况。结果 在进口处具有较高的流速,无节流槽阀芯在阀口处速度降低最大,U型节流槽阀芯在阀口处速度降低最小;U型节流槽阀芯在整个流道内压力变化较小,无节流槽阀芯在整个流道内压力变化最大。结论 阀芯开设节流槽可以明显改善阀流道内流场分布情况,改善阀的性能,其中U型节流槽阀芯具有良好的性能。
英文摘要:
      The paper aims to analyze the fluid field of different valve core structure based on the direct influences of spool valve structure on fluid field of spool valve, so as to improve spool valve performance. U-shaped, triangular and throttling groove-free valve core structures were adopted and the fluid-structure interaction module of ADINA was applied to analyze and calculate the spool valve fluid field and research the fluid speed and pressure distribution condition in the valve channel. The flow rate was high at the valve port. The speed of throttling groove-free valve core decreased the most at the valve port and that of the U-shaped throttling groove valve core decreased the least. The pressure change of U-shaped throttling groove valve core was small in the entire channel, and the pressure change of throttling groove free valve core was the largest. The valve spool with throttling groove could significantly improve fluid field distribution in the valve channel and the performance of valve, in which the U-shaped throttling groove has good performance.
