摘　　要：中国实验快堆典型钠阀作为系统重要的涉钠设备,直接影响着反应堆系统的安全运行。中国实验快堆工程在调试和运行阶段面临着钠阀门带来的一系列问题。本文应用CFD软件计算了两种运行工况下典型钠阀稳态温度场分布,分析了保温层厚度一定、高度不同的情况下,钠阀门的温度场分布结果,并与实验结果进行了对比,证明结果是合理的有意义的。The typical bellows seal sodium valves,as the important equipment in the sodium systems of China Experimental Fast Reactor,have a significant effect on the safety of fast reactors.The typical valves caused some problems in the test stage.The paper is to get the results of temperature distribution in the sodium valve assembly on stable heat transfer condition,using the Computational Fluid Dynamics（CFD） code.The paper also analyses the results computed under the condition of fixed thickness and the different height of thermal insulation materials.It gets a good conclusion through the comparison of measured and simulated results and the numerical simulation result is logical and meaningful.
