<p>PURPOSE:To prevent a separated gas from being leaked from the sliding part of a rotary sliding valve plate used for a gas separating device. CONSTITUTION:Sealed spaces D for enclosing rotary sliding valve plates 2a, 2b, respectively, are formed of an adsorption a tower body 1a slid with the rotary sliding valve plates 2a, 2b, and sliding members such blind patches 3a, 3b, and radial first bypass circuits A, A' are provided on the rotary sliding valve plates 2a, 2b, avoiding opening parts 21a, 21b, 22a, 22b provided for switching the flows, respectively. Further, second bypass circuits B for allowing the sealed spaces D to mutually communicate are provided on the absorption tower body 1a slid with the rotary sliding valve plates 2a, 2b on both the end parts, and a third bypass circuit C for connecting the sealed space D to a specified port of the adsorption tower body is provided on one of the blind patches 3a, 3b slid with the outsides of the rotary sliding valve plates 2a, 2b.</p> |
