The invention discloses a sealing structure for primary and secondary shielding corrugated terminals of a thin film tank, and belongs to the technical field of cryogenic thin film tanks. The sealing structure comprises straight corrugations, a top cambered surface, a side cambered surface I, a bottom cambered surface I, a steel plate body, a side cambered surface II, a bottom cambered surface II and a bottom cambered surface III. The straight corrugations, the top cambered surface, the side cambered surface I, the bottom cambered surface I, the side cambered surface II, the bottom cambered surface II, the bottom cambered surface III and the steel plate body are integrally formed, the straight corrugations are sealed on the steel plate body through the top cambered surface, the side cambered surface I, the bottom cambered surface I, the side cambered surface II, the bottom cambered surface II and the bottom cambered surface III, and the straight corrugations are connected with the corrugations of a main shielding corrugated plate and a secondary shielding corrugated plate of the thin film tank. The sealing structure is easy to form, the forming thinning amount is reduced, the residual stress is reduced, the stress is good, the use is safer, and the convenient sealing of the main and secondary shielding corrugated terminals of the thin film tank is realized.
Description
technical field [0001] The invention relates to the technical field of cryogenic film tanks, and relates to a closed structure for primary and secondary shielding corrugated terminals of film tanks. Background technique [0002] Refrigerated liquefied gases such as liquefied natural gas and liquid hydrogen have become one of the fastest-growing energy industries in the world due to their advantages of greenness, environmental protection and high efficiency. Following this, the application and development of liquefied natural gas and liquid hydrogen have attracted more and more attention from all parties, and liquefied gases such as liquid nitrogen and liquid helium have also been promoted as test media due to their inertness. [0003] Membrane-type storage tanks were first used in the storage of liquefied hydrocarbons and liquefied gases. Due to the high pre-treatment of membrane-type storage tanks, the short construction period, and the low carbon content of the constructio...
