摘　　要：通过双偏心蝶板设计、超低温工况下新型硬密封结构设计,以及主要零件材料选择的研究,研制了DN300-PN10超低温双偏心蝶阀。搭建了超低温蝶阀试验台架,验证了研制的超低温蝶阀在常温或超低温工况下具有良好的密封性能,达到了ANSI/FCI 70-2中Ⅵ级以及JB/T 7749中低温蝶阀密封性能的要求。On the process of research, the following technique is studied：the design of double eccentric butterfly, new structure of hard seal which can be used in ultralow temperature, and material choice etc. Based on the study results, a new ultralow temperature double eccentric butterfly valve is presented and made. Ultralow temperature valve＇s test equipment is constructed. And the result of experimentation shows that the new valve has good seal performance which can attain the seal demand of ANSI/FCI 70 -2 Ⅵ grade and JB/T 7749.
