Abstract

PURPOSE: To check the leakage of a safety valve definitely with safe by detecting a bursting tone of a leaking bubble on the surface of water by a microphone when detecting the existence of a leaking bubble in a water filling test of the safety valve.
CONSTITUTION: At the opening surface of outlet flange 6 of safety valve 1, tape 8 is horizontally provided as a water storage barrier and valve box 2 is filled with water to put the safety-valve outlet side of contact part 5 between valve body 3 and valve seat 4 under water. Next, pressure gas such as N2 is led in from duct 9 for testing pressure gas connected intake flange 7 of safety valve 1. Then, it is detected whether or not the bubble of the pressure gas leaking from contact part 5 between valve body 3 and valve seat 4 appears on water surface 10 in valve box 2. The existence of this leaking bubble is judged by detecting the bursting tone of the gas on water surface 10 by microphone 11.
