摘要：
Dome gas lift is the technical difficulties of a large LNG (liquefied natural gas) tanks in the process of construction. The sealing structure is one of the core link in the process of the gas lift. In this paper, the seal structure of large LNG storage tank dome gas lift is studied. A new kind of sealing structure is designed by using gap seal. This paper has carried on the simulation analysis with ANSYS software to verify the feasibility of new type sealing structure. This kind of sealing structure can reduce the friction in the process of gas lift. It also can use the smaller contact area to achieve good sealing effect. The method has important practical value in enhancing the security of gas lift of LNG storage tank dome.
