放点検するための船体海水吸入口閉塞構造におい
て、海水吸入管開口より若干大径の盲板と、上記
盲板の外面央部に突設された圧力流体給排用注排
弁と、上記盲板の内面に開口端が流体密的に固着
され収縮したときには上記海水吸入管に内挿する
ことができるとともに圧力流体の供給により膨張
したときには外周面が上記海水吸入管に水密的に
密接することができる膨縮性ベローズとを具えた
ことを特徴とする船体海水吸入口水密栓。 In a hull seawater inlet closing structure for opening and inspecting the outer plate valve of the seawater inlet pipe while the ship is floating, a blind plate with a diameter slightly larger than the seawater inlet pipe opening is provided, and a blind plate is provided protruding from the center of the outer surface of the blind plate. The open end is fluid-tightly fixed to the inner surface of the blind plate, so that it can be inserted into the seawater suction pipe when it is contracted, and the outer periphery can be inserted into the seawater suction pipe when it is expanded by supplying pressure fluid. A seawater inlet watertight plug for a ship body, comprising an expandable bellows whose surface can be brought into close watertight contact with the seawater inlet pipe.
