Abstract
A dilution device may include a first component and a second component. The first component may define a groove including an inlet portion and an outlet portion. The second component may define an inlet in fluid communication with the inlet portion of the first component and an outlet in fluid communication with the outlet portion of the first component. Relative rotation between the first component and the second component may cause relative movement between the outlet and the outlet portion that changes the effective length of the groove fluidly coupling the inlet and the outlet of the second component. The cross-sectional area of the groove may vary along a length of the groove to provide different flow characteristics depending on the effective length of the groove.
Claims20
A dilution device, comprising:
- a metering disc having a cross-sectional thickness, the metering disc defining a metering groove having an inlet portion and an outlet portion, the metering groove formed in a surface of the metering disc and having a depth that is less than the cross-sectional thickness of the metering disc;
- and
- a housing comprising a first housing component coupled with a second housing component,
- wherein the first and second housing components define an interior of the housing enclosing the metering disc, the second housing component defining an inlet in fluid communication with the inlet portion of the metering groove and an outlet in fluid communication with the outlet portion of the metering groove, the inlet and the outlet each extending through the second housing component from the interior to an exterior of the housing, the inlet configured for receiving a chemical and the outlet configured for coupling with an eductor defining a motive fluid passage,
- wherein relative rotation between the metering disc and the first or second housing component causes relative movement between the outlet and the outlet portion that changes an effective length of the metering groove fluidly coupling the inlet and the outlet.
A dilution system, comprising:
- a dilution device defining a flow channel in fluid communication with a concentrated chemical;
- and
- an eductor in fluid communication with the flow channel and a motive fluid,
- wherein the motive fluid flows through the eductor and creates a suction force that draws the concentrated chemical through the flow channel defined by the dilution device and into a flow path of the motive fluid to mix the concentrated chemical with the motive fluid.
