The invention provides a liquid discharge device for a liquid tank containment system and a ship. The liquid discharge device comprises an upper end body, a connecting flange is arranged at one end of the upper end body in the length direction, a liquid cavity communicating with the connecting flange is formed in the upper end body, and an opening extending outwards is formed in the abdomen of the liquid cavity; through holes are formed in the lower end main body, the shape of the lower end main body is a polygon with at least one long edge, and the through holes are distributed along the long edge; the film is arranged between the upper end main body and the lower end main body; the metal sheet is arranged at the opening of the liquid cavity and located above the thin film, the blade is arranged at the free end of the metal sheet, and when liquid flows into the liquid cavity along the connecting flange and makes contact with the metal sheet at the opening of the liquid cavity and the liquid is accumulated to a preset volume at the opening, the blade cuts the thin film; and the liquid is discharged from the cut part of the film along the through hole in the lower end main body. According to the liquid discharging device, large-deflection deformation of the metal sheet in a small-temperature-difference environment can be achieved, and the application range is wide.

    本申请提供一种用于液舱围护系统的液体泄放装置及船舶,包括上端主体,沿长度方向上端主体的一端设有连接法兰,上端主体的内部设有与连接法兰连通的液腔,液腔的腹部开设有向外部延伸的开口;下端主体,内设通孔下端主体的形状为具有至少一个长边的多边形,通孔沿所述长边布设;薄膜布置在上端主体和下端主体之间;金属片布置在液腔的开口处,位于薄膜的上方,刀片布置在金属片的自由端,当有液体沿连接法兰流至液腔内,在液腔的开口处接触金属片,当液体在开口处累积至预设体积时,刀片割破薄膜,液体通过薄膜被割破处沿下端主体上的通孔泄放出去。本申请中的液体泄放装置可以实现金属片在小温差环境下的大挠度变形,使用范围广。
