LNG接收站工程超低温阀门选型研究

Type Selection Study of Cryogenic Valves in LNG Receiving Terminal Plant

文中结合国内外标准要求和工程经验做法,对比了各阀门形式的优劣,讨论了阀门的结构设计要求和材料选型要求,提出了一套关于阀门形式、结构、材料的选型方法。根据该选型方法,通过项目实例列出了某项目详细的阀门选型方案,证明该选型方法的有效性。

This paper combined with the domestic and international standard requirements and engineering experience,and compared the advantages and disadvantages of each valve type,discussed the structural design requirements of valve and material selection requirements,and put forward a set of selection methods of valve type,structure and material.According to the type selection method,the detailed valve selection scheme of a project was listed through the project example,which proved the effectiveness of the type selection method.
