摘　　要：阀碟型线对汽轮机进汽阀的性能影响很大，本文设计了三种形式的基元阀，通过数值模拟手段研究了阀碟型线对流场的影响；得出了不同阀碟形式的性能．The performance of live steam valve for steam turbine is greatly influenced by the profile of valve disc. Three types of elementary valves are designed. Numerical method is employed to simulate the flow field inside elementary valves and to investigate the performance of live steam valve.
