PIPING STRUCTURAL BODY FOR SODIUM LEAKAGE DETECTOR

摘要

PURPOSE:To eliminate an unevenness of a sodium detecting function and to improve the function by connecting a nozzle tube having plural holes at a tip end of a sampling piping and holding the nozzle tube between flange structural parts of an interior plate. CONSTITUTION:An outside of a piping 1 for sodium current is surrounded by an interior plate 3 having a flange structural part 33, and the outside thereof is covered with heat insulator. An annulus part 6 is formed between the piping 1 and the plate 3. A nozzle 31 having plural holes 30 is connected to the sampling piping 29, and the nozzle 31 is held between a pair of the flange structural parts 33 and fixed by a screw 34. In this way, the sampling can be performed uniformly also from the places distant from the nozzle 31, and the function of the whole leakage detecting system is improved.
