| Abstract: | Based on Limited Element method,the stress and tightness of ball valve used in LNG carrier were analysed at ultra-low temperature.The stress values of valve stem,valve neck and valve cover at low temperature were studied.The result of the study shows the stress concentration area of the ball valve at low temperatures and proposed improvement measures.The result also provides theoretical guide the designation of the cryogenic valve. |
