Segmented tightness testing method

Abstract

The invention discloses a segmented tightness testing method. A hole to an inner welding seam is drilled on a well-welded segmented outer wall surface; the periphery of the hole is welded with an air testing device for realizing inner air supply; a leakage detection device is arranged on a welding strip for detection a leakage point; the air testing device is connected with an air compressor via an air tube; the air inlet of the air compressor is provided with an atomizer loaded with iodine water, and thus air sucked by the air compressor contains iodine vapor for filling the welding seam with iodine-containing air; the air testing device fills air inside the welding seam, the leakage detection device moves on the welding strip for testing whether air leakage exists; and the leakage detection device is internally provided with starch water, in case of air leakage, a color is changed as the air contains iodine, and the detection effects are obvious.

Description

technical field [0001] The invention relates to a segmented tightness test method, in particular to a welded seam tightness test used for the segmental exterior in contact with seawater, and belongs to the technical field of ships. Background technique [0002] The water injection inspection of the ship is to press the water to the specified height according to the requirements of the specifications according to different parts, so that the hull structure and welds are in a certain state of pressure, and then check the leakage of the welds. But this method has following limitation in use: (1) must install water supply and drainage system, the waste of time and manpower is very big, when particularly testing the larger cabin of volume; (3) After the test, the ship and the berth were wet and dirty. After the test, the scaffolding and ladders in the cabin were wet and slippery, and the construction and repair work in the cabin before drying was inconvenient; (4) When the diffe...
