图1为一低温贮罐结构图。贮罐主要有内容器、外壳、真空夹层、内外管路及内外支撑等组成内容器用来盛装低温液体,其外表面包扎有多层绝热材料,并通过绝热性能良好的内支撑与外罐连接,外罐与内容器构成密闭的真空夹层绝热空间,外管路及操作系统置于外罐的下部。管路系统具有加排液、自增压、安全保护、液面高度及压
Figure 1 shows a cryogenic tank structure. The storage tank is mainly composed of an inner container, a shell, a vacuum interlayer, inner and outer pipes, inner and outer supports, etc. The inner container is used to contain cryogenic liquid. The outer surface of the storage tank is wrapped with a plurality of layers of thermal insulation materials, connected with the outer tank through the inner support with good thermal insulation properties, The outer tank and the inner container form a sealed vacuum interlayer insulating space, and the outer pipe and the operating system are placed in the lower part of the outer tank. Piping system with plus drainage, self-pressurization, safety protection, liquid level and pressure
