摘　　要：按照负载敏感平衡阀的设计参数,应用Pro/E软件建立了平衡阀内节流阀芯的三维几何模型,运用Fluent前处理软件Gambit进行了网格的划分。采用标准紊流模型模拟了节流阀流道内流体的流动状态及漩涡的产生区域,通过截取各个阀芯小孔处的平均速度,从而验证流量的稳定性。所得结论为阀芯的结构设计与优化提供了参考依据。According to the design parameters of the load-sensing counterbalance valve,three-dimensional geometric model of throttle valve core in counterbalance valve is established by using Pro/E software and the division of the grid is carried by using pre-processing software Gambit.In a given four kinds of pressure and the corresponding four kinds opening amount of valve core,flow state of fluid in fluid channel of throttle valve and the emergence of vortex region are simulated by using standard turbulent flow model,and through the average speed of each small holes on valve core is intercepted,thereby flow stability is verified.The conclusion provides a reference for the structural design and optimization of valve core.
