The invention provides a marine liquid tank. The marine liquid tank comprises a tank body, a tank body joint and an interlayer pipeline. The tank body comprises an inner tank used for storing low-temperature liquid and an outer tank wrapping the inner tank, and a heat insulation interlayer is formed between the inner tank and the outer tank. The tank body joint comprises a shell and a connecting pipeline fixed in the shell, the shell is arranged on the peripheral side wall of the outer tank and extends in the axial direction of the outer tank, and a hollow containing cavity is defined between the shell and the outer tank. The interlayer pipeline comprises a plurality of pipe sections which are sequentially connected in a bent mode, the inner end of the interlayer pipeline is communicated with the inner tank, and the outer end of the interlayer pipeline penetrates through the outer tank and extends into the containing cavity to be connected with the connecting pipeline. And the tank body joint is arranged on the side wall of the outer tank, so that the space in the width direction of the ship body is fully utilized, the space in the length direction required for mounting the tank body is not occupied, the loading volume of the tank body is increased, and the cruising ability of marine operation of the ship is ensured.
本发明提供了一种船用液罐,其包括罐体、罐体连接处所和夹层管路。其中,罐体包括用于储存低温液体的内罐和包覆于内罐外部的外罐,内罐和外罐之间形成有绝热夹层。罐体连接处所包括外壳和固定于外壳内的连接管路,外壳设于外罐的外周侧壁上并沿外罐的轴向延伸,外壳与外罐之间围合形成一中空的收容腔。夹层管路包括多个依次折弯相连的管段,夹层管路的内端与内罐连通,夹层管路的外端穿过外罐并伸入收容腔内与连接管路连接。罐体连接处所设于外罐的侧壁上,充分利用了船体的宽度方向上的空间,而不占据罐体安装所需要的长度方向上的空间,增加了罐体的装载容积,保证了船舶海上运行的续航能力。
