Provided is a gas-dissolved water generating apparatus in which a pressure pump and a multi-stage mixer are sequentially arranged on at least one conduit; a circulation pipe connecting an inlet side of the pressure pump and a outlet side of the pressure pump is positioned on the conduit; a gas supply unit for supplying a predetermined external gas to one side of the circulation pipe, which is connected to the inlet side of the pressure pump, via a gas supply pipe; the gas supply unit and the circulation pipe are connected through a three-way valve, and the three-way valve is configured to have a structure of a venturi pipe having wide inlet and outlet channels and a narrow interior channel along the circulation pipe, so that a gas supplied from the gas supply unit is independently sucked.

An object of the invention is to prevent differences in the flow rate and the specific gravity of a gypsum slurry from being caused between slurry discharge ports, to divide a current of the slurry into streams without a factor of stagnation of the slurry provided at a branch part, and also, to ensure a sufficient distance between the discharge ports.

The slurry delivery conduit (10) has a rectilinear tube segment (14), a branch part (15) and branch tube segments (16). A tube-wall joint portion (20) of the branch tube segments configures a counter-flow splitting element (22) in a form of V-letter at the branch part. The slurry is introduced from a mixing area (51) into the rectilinear tube segment, which configures a straight rectilinear fluid passage. The rectilinear tube segment rectifies a flow of the slurry to be an axial or rectilinear current (S), and the axial or rectilinear current is split into branch streams (S1, S2) by the counter-flow splitting element.
