<p>PURPOSE:To cool inside and outside bellows, while detecting early the leakage of cooling fluid by letting the cooling fluid flow in a space between the inside and outside bellows and providing a calculator for detecting the leakage of the cooling fluid. CONSTITUTION:An inside bellows 24 and outside bellows 25 provided concentrically with the outside of the inside bellows 24 are mounted between two flanges 20, 22. A space 26 is provided between the inside and outside bellows 24, 25. Cooling fluid is supplied into the space 26 through a cooling fluid supply pipe 28, supply side flow meter 27 and cooling fluid supply pipe 28 by operating a pump 31. When the inside bellows 24 or the outside bellows 25 is broken, the cooling fluid flowing in the space 26 leaks from the broken portion, so that the measured flow of the exhaust side flow meter 29 becomes fewer than that of the supply side flow meter 27. When a difference between the flows exceeds an allowable value, a calculator 35 outputs a trip signal 36.</p> |
