Abstract

PURPOSE:To enable the repeated extraction of a dissolved gas in a liquid and even that with a higher dissolubility by connecting a cylinder chamber of a reciprocating piston unit to a deairing vessel so as to be connected to a vacuum pump. CONSTITUTION:A piston 7b of a reciprocating piston unit 7 is moved to the right with a differential pressure piston unit 20 to open valves 5 and 8 and a three-way changeover valve 9 is actuated to communicate a cylinder chamber 7a and gas sample tubes 14a and 14b to a vacuum pump 10. When the cylinder chamber 7a and the like attains a specified vacuum state, the changeover valve 9 is switched over to let an electrically insulating oil in a sample oil extractor 4 flow into a deairing vessel 1 and actuate an agitator 2 to separate and release a dissolved gas. At this point, the valve 5 is closed and as the piston 7b moves, the dissolved gas is forcibly transferred into the gas sample tubes 14a and 14b. The deairing extraction of the dissolved gas is repeated by repeating this procedure. The differential pressure piston unit can eliminate a pressure device if the pressure receiving area thereof is set at 3-3.5 times as large as that of the reciprocating piston unit.
