Abstract

PURPOSE: To detect and discharge the leaked fluid in the double bottom of a double- bottomed tank or sump by arranging a pressure gauge and a pressure switch in the double bottom kept pressurized.
CONSTITUTION: A sump 1 is constructed in a double-wall structure of an inner wall 2 and outer wall 3, in whose gap 5 a discharge pipe 10 connected to a pressure gauge 8 and a pressure switch 9 is inserted. To the pressure switch 9, an alarm 11 is connected, while from the discharge pipe 10, a branch pipe with a valve 12 branches off. Besides, a gap 5 is kept pressurized by a pressure line 7. When fluid leaks from the sump 1 into the gap 5, the pressure in the gap 5 is increased. This increase of pressure is caught by the pressure gauge 8, and the alarm 11 is operated by the pressure switch.
