摘　　要：分析了低温阀门的低温介质对填料密封性能的影响,建立了合理简化的长颈阀盖物理模型和阀盖颈部长度与温度场关系的数学模型,论述了长颈阀盖温度场的分布,推导了阀盖颈部长度与温度场的关系式,得到了满足阀门设计标准的阀盖最短长度。The influence of the cryogenic liquid flow on the performance of the packing is analyzed in this paper and a mathematical model on the relationship betw een the length of the bonnet neck and the temperature field is established after the reasonably simplified physical model of the structure of long-neck bonnet. The minimum length of the bonnet satisfying the designing standard is obtained through the relation of the length of the bonnet neck and the temperature field concluded by analyzing the distribute of the temperature field. And therefore w e can provide a theoretical basis for engineering design.
