Title:
CHEMICAL LIQUID DILUTING APPARATUS
Document Type and Number:
Japanese Patent JP3149166
Kind Code:
B
Abstract:
PROBLEM TO BE SOLVED: To lower the cost by making a flow rate-regulating valve, which is conventionally required, unnecessary and to control the concentration of a chemical agent diluted with a narrow alteration magnitude even if the flow rate of tap water is fluctuated.
SOLUTION: A tank 46 containing a chemical liquid is housed in a case and the case and an ejector 44 are fixed. That is, the tank 46 and the ejector 44 are positioned in a fixed state. Consequently, a flow rate-regulating valve, which is a conventionally required, is made unnecessary. Further, the head difference between height of the liquid surface of the chemical liquid in the tank 46 and the height of the communication position of the chemical liquid introduction route to the negative pressure generation part of the ejector 44 can be kept within a narrow range and thus the fluctuation of the concentration by dilution can be suppressed or eliminated even if the flow rate of tap water is increased.
