Abstract

The need for natural gases has recently been increasing for energy production and demand. Accordingly, many different studies are now being conducted on ways to supply liquefied natural gases (LNG) and on the valves that are used to supply those gases. Although there are various types of valves that are used at extremely low temperatures, vacuum jacket valves, which minimize the heat leak by using lean gases in the vacuum layer, are mostly used. In this regard, this study verified the results of a numerical analysis through thermal analysis and experiments on a vacuum jacket valve at extremely low temperatures (-179øC). Based on this data, a heat leak was calculated to evaluate thermal performance. In addition, a thermal-structural coupled field analysis was conducted in order to consider thermal stress and deformation caused by extremely low temperatures. Based on this analysis, the study aims to evaluate the structural stability of a vacuum jacket valve and provide the results as basic data
