<p><P>PROBLEM TO BE SOLVED: To surely and quickly detect leakage water of a hose connecting pipe coupling. <P>SOLUTION: This hose connecting pipe coupling includes a pipe coupling tip part 11 of a circular pipe shape inserted into a hose tube hole 2a from the rear end of a hose 2, a sleeve 20 arranged so as to cover the outer periphery of a rear end part of the hose 2 in a concentric circle shape and sandwiching the hose 2 between the tip part 11 and itself, and a heating layer 3 for covering the outer periphery of the sleeve 20 and the hose 2 over the hose 2 from the sleeve 20 and reacting with cooling water by heating. Since the heating layer 3 is heated when the cooling water leaks from between the hose 2 and the pipe coupling, the leakage water can be sharply detected by a temperature sensor. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
