The invention discloses a ship and a liquid cargo tank air pressure control method. The ship comprises a liquid cargo tank containment system, a cabin used for storing the liquid cargo tank containment system and an air pressure control device. The liquid cargo tank containment system comprises an insulating layer and a liquid cargo tank, and an insulating space is formed between the insulating layer and the liquid cargo tank; the outer side of the insulating layer and the interior of the cabin form a liquid cargo space; a balance hole penetrating through the insulating space and the liquid cargo tank is formed in the insulating layer; the air pressure control device controls opening or closing of the air inlet assembly of the insulation space, the air inlet assembly of the liquid cargo tank and the air outlet assembly of the liquid cargo tank according to the collected first air pressure value and second air pressure value. The liquid cargo tank air pressure control method is applied to the ship. The insulation space and the liquid cargo tank keep balance all the time, stress of the insulation layer can be reduced, and the risks of insulation layer damage and cabin hull structure deformation are effectively reduced. In addition, the introduced inert protective gas is changed into air, so that the air of the cargo tank can be simply and quickly realized.

    本发明公开了一种船舶及液货舱气压控制方法,船舶包括液货舱围护系统、用于存储液货舱围护系统的舱室以及气压控制装置;液货舱围护系统包括绝缘层和液货舱,绝缘层与液货舱之间形成绝缘空间;绝缘层的外侧和舱室的内部形成液货舱处所;绝缘层上设置有贯通绝缘空间和液货舱处所的平衡孔;气压控制装置根据收取的第一气压值和第二气压值来控制绝缘空间进气组件、液货舱处所进气组件和液货舱处所出气组件开启或关闭。液货舱气压控制方法应用于如上的船舶。绝缘空间和液货舱处所时刻保持平衡可以减小绝缘层的受力,有效降低绝缘层破损以及舱室船体结构变形的风险。此外,将通入的惰性保护气体换成空气即可简单快捷地实现液货舱处所的空气化。
