The invention belongs to the technical field of ship tools, and discloses an outboard pipe plugging tool, a packaging method and a method for replacing a sea valve on water. The outboard pipe plugging tool comprises an air bag and a control unit. The air bag can be placed in the outboard pipe through the water inlet, the air bag is connected with a first communicating pipe, and the air bag can block the outboard pipe after being inflated so as to prevent seawater from entering the ship body. The control unit comprises an air inlet and a release valve, the air inlet and the release valve are both communicated with the first communicating pipe, air can enter the air bag from the air inlet through the first communicating pipe, and the air in the air bag can be discharged from the release valve through the first communicating pipe. The blocking tool is simple in structure, reasonable in design and reliable in sealing performance, by means of the blocking tool, an operator can block the outboard pipe without entering water, operation is safe, cost is low, and the ship production process cannot be affected.
本发明属于船舶工装技术领域,公开了一种舷外管封堵工装、封装方法及水上水上更换通海阀的方法。该舷外管封堵工装包括气囊和控制单元。气囊能够通过入水口放置在舷外管内,气囊连接有第一连通管,气囊充气后能够将舷外管封堵,以防止海水进入船体。控制单元包括进气口和泄放阀,进气口和泄放阀均与第一连通管连通,气体能够从进气口经第一连通管进入到气囊中,气囊中的气体能够经第一连通管从泄放阀排出。该封堵工装结构简单,设计合理,密封性可靠,采用该封堵工装,操作人员无需下水即可进行舷外管的封堵工作,操作安全,成本低,也不会影响船舶生产进程。
