摘　　要：运用CFD软件对一种高压截止阀进行了三维数值模拟,对截止阀不同的内流道结构进行流动分析。通过对典型的高压截止阀结构进行建模,借助CFD软件分析了阀门内部流场的流动特性,给出了优化的内流道结构的分析结果及产品设计的理论依据。The globe valve is commonly used in industrial system, it is easy to overlook the internal flow characteristics in the valve design, and lead to unnecessary energy consumption. By model the structure of a typical high - pressure globe valve, The internal flow field, with the CFD software to. The analysis results show that;closing the flow coefficient of the valve with the valve opening height first increases, reaches a certain value, the declining trend;valve flap fillet size change of the flow coefficient is smal- ler, there is an optimal value.
