摘　　要：为了探究锥形旋塞阀内部流体动态特性,需对旋塞阀结构进行优化设计。本文基于k-ε湍流模型,使用开源软件OpenFOAM、应用PIMPLE算法、以锥形旋塞阀为研究对象,模拟研究了不同开度、不同阀芯圆角时旋塞阀的流动性能;研究了阀芯关闭过程中随着旋转角度的增加,流体流速、压差、流线、流量系数以及阻力系数等参数的变化规律,并绘制了相关曲线;对比分析了不同圆角半径下流体介质的速度、流量系数曲线等参数的变化。结果表明:旋塞阀旋转角度越大,阀门前后压差越大,流量损失也就越大;流量系数随着旋塞阀开度的增加而减小,且在相同开度下随着阀芯圆角半径的增加而增大。To investigate the dynamic characteristics of fluid inside a conical plug valve and to optimize the valve structure,this paper used the open-source software OpenFOAM based on the k-turbulence model and the PIMPLE algorithm.The study simulated and analyzed the flow performance of the conical plug valve under different openings and different valve core fillet radii.The variation of fluid velocity,pressure drop,streamlines,flow coefficient,and resistance coefficient during the valve core closing process as the rotation angle increased were investigated,and relevant curves were plotted.The changes in fluid velocity and flow coefficient curves under different fillet radii were analyzed.The results showed that as the rotation angle of the plug valve increased,the pressure difference before and after the valve increased,resulting in greater flow loss.The flow coefficient decreased with the increase of the valve opening and increased with the increase of the valve core fillet radius at the same opening,which can provide a reference for the optimization of the conical plug valve structure.
