A method for repairing the sea valve of a surface ship in the mooring state and a plugging tool suitable for the method

Abstract

The invention relates to the technical field of sea valve maintenance, and specifically discloses a method for repairing the mooring state of a sea valve on a surface ship, which temporarily blocks the suction grid of the sea valve box to establish a waterproof environment required for repairing the sea valve, including: according to The size of the suction grille of the sea valve box is made of a plugging tool that is suitable for the suction grille; the suction grille is blocked by the plugging tool; the sea valve is dismantled, overhauled or replaced from the inside of the cabin; after troubleshooting, reinstall Sea valve; remove plugging fixture from suction grille. In addition, the present invention also provides two special plugging tools suitable for the above method. The invention solves the problem that the ship cannot safely repair the sea valve in the mooring state, provides a fast, safe and feasible method for repairing the sea valve in the mooring state of the wharf, and avoids docking of the ship due to the maintenance of the sea valve Or the upper row, wasting a lot of manpower and material resources, while ensuring the safety of the ship, it also saves the maintenance cycle.

Description

technical field [0001] The invention relates to the technical field of sea valve maintenance. Background technique [0002] When the surface ship is moored at the wharf, if the sea valve is damaged, a large amount of seawater will enter the cabin, which will pose a threat to the safety of the ship. Due to the frequent opening and closing of the sea valve, the seal may not be tight during the working period of half a year to one year. At present, in order to ensure the safety of the ship, the sea valve is mainly repaired after the surface ship is docked. However, docking and repairing of ships requires a lot of work, time-consuming, and requires a lot of manpower and material resources. The cost of docking is as high as tens of thousands of yuan a day. Ships usually take one year or even several years to dock for maintenance. The timely maintenance of the sea valve will bring great hidden danger to the safety of ship navigation. Contents of the invention [0003] The pur...
