GAS DISSOLVING APPARATUS THAT A LIQUID SUPPLY VALVE AND A GAS VALVE ARE OPERATED SIMULTANEOUSLY

摘要

PURPOSE: A gas dissolution system is provided to optimize dissolution efficiency, and to obtain a convenience of operation by gearing the opening and closing of a valve for fluid supply with the opening and closing of a valve for gas supply. CONSTITUTION: A gas dissolution system (100) comprises: a dissolver (50) supplied with fluid and gas, and discharges the solution obtained by dissolving the gas in the fluid; A fluid supply tube (10) providing a route for supplying the fluid in the dissolver from the external fluid source; a gas supply tube (20) providing a route for supplying the gas in the dissolver from the external gas source; a water supply valve (15) for opening and closing the fluid supply tube; a gas valve (25) for opening and closing the gas supply tube; and an interlocking means which connects the gas valve and water supply valve to open and close a valve between the two valves by gearing with the opening and closing of the other valve.
