摘　　要：介绍了乙烯装置用低温阀门阀盖延伸部位在生产过程中结冰现象的原因和危害。通过有限元分析方法,分析和验证了在阀盖及阀杆外延部分增加径向吸热片的可行性。提出了在滴水盘上方阀盖及阀杆延伸表面安装径向吸热片,增加传质传热表面积的方法,消除阀盖及阀杆填料外部结冰现象。Introduces the causes and hazards due to freezing at the extension part of the cryogenic valve applied in the ethylene unit during the production process. By the finite element analysis method,analyzes and verifies the feasibility of mounting radial heat sink at the extension part of the valve stem,puts forward a method of mounting radial heat sink above the drop plate,namely above the extension part of the valve stem,to increase the mass transfer and heat transfer surface area,to avoid freezing.
