The invention relates to the technical field of ships, and discloses a ship seawater system drainage device and a drainage method thereof. The ship seawater system drainage device comprises a working header pipe, a discharge pipe and a gas supply pipe, the working header pipe comprises a water inlet and a water outlet, the water inlet is communicated with a sea chest, the water outlet is communicated with a ship water device, a water inlet section is arranged between the water inlet and a designed waterline, and a water using section is arranged between the designed waterline and the water outlet; one end of the discharge pipe is communicated with the water inlet section, the other end of the discharge pipe is communicated with the sea chest through a discharge valve, and a before-pump isolating valve is arranged between the water inlet and the discharge pipe; one end of the gas supply pipe is communicated with the water section, the other end is communicated with the gas supply device through an injection valve, and a header pipe isolation valve is arranged between the water outlet and the gas supply pipe; when the pump front isolating valve and the main pipe isolating valve are closed, the release valve and the injection valve are opened, and gas can enter the working main pipe to discharge water stored in the working main pipe. The drainage speed is high, the drainage time is saved, and meanwhile drainage is more thorough.

    本发明涉及船舶技术领域,公开一种船舶海水系统排水装置及其排水方法。其中船舶海水系统排水装置包括工作总管、泄放管和气体供应管,其中工作总管包括进水口和出水口,进水口与海底门连通,出水口与船舶用水装置连通,进水口与设计水线之间为进水段,设计水线和出水口之间为用水段;泄放管一端与进水段连通,另一端通过泄放阀与海底门连通,进水口与泄放管之间设置有泵前隔断阀;气体供应管一端与用水段连通,另一端通过注入阀与气体提供装置连通,出水口与气体供应管之间设置有总管隔离阀;泵前隔断阀和总管隔离阀关闭,泄放阀和注入阀打开,气体能进入工作总管以排出工作总管内的存水。本发明排水速度快,节约排水时间,同时排放地更加彻底。
