초저온 환경에서의 Blind Flange Valve 구조안정성평가

Blind Flange Valves (BFV) are usually installed to ensure complete segregation between various grades of cargoes, blanking off parts of pipeline systems, etc. In this paper, numerical investigation of typical BFV under cryogenic condition, which includes fluid field analysis using CFD, stress verification using direct coupling analysis in ANSYS, are presented. Through this way, whether this BFV could work normally or not under cryogenic condition is verified, moreover, the effects of imported fluid and cryogenic temperature could be understood very clearly.
