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.
Claims19
A dilution device, comprising:
- a first component defining a groove including an inlet portion and an outlet portion;
- and
- a second component defining 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;
- wherein:
- relative rotation between the first component and the second component causes 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;
- and
- the cross-sectional area of the groove varies along a length of the groove to provide different flow restriction depending on the effective length of the groove.
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 into the flow path of the motive fluid to mix the concentrated chemical with the motive fluid.
A method of diluting a chemical concentrate with a fluid, the method comprising:
- biasing a metering disc into engagement with an eductor body to form a flow channel between the metering disc and the eductor body;
- sealing the flow channel by deforming one of the metering disc or the eductor body with ridges on the other of the metering disc or the eductor that extend along edges of the flow channel;
- and
- rotating the metering disc relative to an eductor body to change an effective length of a metering groove fluidly coupling a concentrated chemical and a motive fluid to vary dilution of the concentrated chemical.
