【Abstract】 The finite element analysis model is created by using SolidWorks software,and the temperature field and thermal coupling analysis of LNG low temperature check valve in a valve enterprise are carried out by using ANSYS finite element analysis software. The maximum deformation and its position of the check valve under the ultra-low temperature test condition at-196 ℃ are obtained,which provides a reference significance for the further study of the structural optimization design of the ultra-low temperature check valve.更多还原
