Being the port detection device which detects the port which it occurs in the port detection

摘要

PROBLEM TO BE SOLVED: To provide a leakage hole detecting device for a pipe body, enabling detection of a leakage hole with high accuracy, by removing bubbles deposited on the outside surface of a detected object, prior to detecting the bubbles generated from a leakage hole of the detected object.;SOLUTION: The leakage hole detecting device comprises a storage body 40 which stores liquid and through which the pipe body passes inside the liquid, a first suction part 10 provided in the storage body 40 for sucking bubbles, together with the liquid around the pipe body to remove the bubbles deposited on the outer face of the pipe body passing through the liquid; a second suction part 20 provided in the storage body 40 for sucking the bubbles leaking from the inside of the pipe body passing through the first suction part 10 together with the liquid around the pipe body; and a detection part 50 for detecting the bubbles in the liquid sucked by the second suction part 20.;COPYRIGHT: (C)2009,JPO&INPIT
