SEALING DEVICE FOR TANK LEAK TEST OF SHIP

摘要

PURPOSE: A sealing device for testing a leakage of a tank of a ship is provided to have no need to perform works for separating and installing a bellmouth, which is installed for a leakage test, by closing/opening an opening of a pipe by a magnetic force by a cover when testing the leakage. CONSTITUTION: A sealing device(30) for testing a leakage of a tank of a ship opens/closes an opening(41) of a pipe(20) connecting the inside and the outside of the tank for a tank leakage test. The sealing device comprises a magnetic force generating unit(31) and a cover. The cover is attached to the pipe by the magnetic force, thereby sealing the opening of the pipe.
