<p>PROBLEM TO BE SOLVED: To provide a gas leakage monitor which can automatically supply gas for shortage of gas upon the occurrence of gas leakage.SOLUTION: A pipe body connection part 8 for connecting an end opening 4 of a first main pipe 3 connected to first gas equipment 2 and an end opening 7 of a second main pipe 6 connected to second gas equipment 5 is surrounded airtightly by a connection part cover 9 and is stored inside. When first gas pressure Ry1 which is gas pressure in the connection part cover 9 is lower than second gas pressure Ry2 which is gas pressure in the gas equipment, a gas cylinder 20 and an electric valve 23 are controlled for supplying gas in the connection part cover 9 from outside, thereby gas for shortage is supplied into the connection part cover 9.</p> |
