The invention provides a thermal insulation system of a liquid cargo tank, which comprises an elastic support sheet arranged on the outer side of a liquid cargo tank shell, the elastic support sheet is a stainless steel metal sheet, a raised isolation cover part of the elastic support sheet is circular, and a middle circular plate area is provided with a fastening bolt connected with the liquid cargo tank shell. One side of the elastic supporting piece makes contact with the first heat preservation plate, the other side of the elastic supporting piece makes contact with the second heat preservation plate and the third heat preservation plate, and therefore heat loads are effectively transmitted, and the connection relation between the elastic supporting piece and all the heat preservation plates is kept to improve stability. The cushion block is welded to the surface of the liquid cargo tank shell, one end of the fastening bolt is connected to the cushion block in a butt-welding mode, the other end of the fastening bolt is connected with the elastic supporting piece through the nut, and when the butt-welding quality problem occurs, the liquid cargo tank shell cannot be damaged by re-butt-welding. The thermal insulation system has a good thermal insulation effect, meanwhile, gaps exist between the layers of thermal insulation plates, stress deformation caused by thermal expansion and cold contraction is avoided, meanwhile, certain building precision deviation can be allowed, and the construction difficulty is reduced.

    本发明提供一种液货舱的保温系统,该保温系统包括设于液货舱壳体外侧的弹性支撑片,弹性支撑片为不锈钢金属薄片,其凸起的隔离罩部分为圆形,中间的圆板区域安装了紧固螺栓与液货舱壳体连接。弹性支撑片的一侧与第一保温板接触,另一侧与第二保温板、第三保温板接触,从而有效地传递热载荷,与各个保温板保持连接关系提升稳固性。液货舱壳体的表面焊接有垫块,紧固螺栓的一端采用碰焊形式连接于垫块上,另一端与弹性支撑片通过螺母连接,当碰焊出现质量问题时,重新碰焊不会对液货舱壳体造成损伤。该保温系统具有良好的隔热效果,同时各层保温板之间存在间隙,避免了热胀冷缩引起的应力形变,同时能够允许一定的建造精度偏差,降低了施工难度。
