Claims

[Scope of Claim for Utility Model Registration] A device that continuously supplies a diluted solution of a predetermined concentration by mixing a stock solution and raw water, which includes a circulating loop pipe for dilution and forcing the mixed solution inside the loop pipe. A pump for circulating the liquid, a raw water supply means for supplying the raw water to the loop pipe, a raw water supply means for supplying the raw water to the loop pipe, a diluent discharge means for discharging the circulating diluted liquid, and a circulating liquid in the loop pipe. a means for adjusting the flow rate; a first chamber communicating with the stock solution supply means and communicating with the pump upstream side of the loop pipe via a small path; and a second chamber communicating with the pump upstream side of the loop pipe; The device includes a diaphragm as a partition wall that partitions the first chamber and the second chamber, and an on-off valve fixed to the diaphragm to open and close the small path, and controls the mixed amount of the stock solution according to pressure changes in the circulation loop pipe. A liquid continuous dilution device comprising: a stock solution mixing amount adjustment means; and a liquid continuous dilution device.
