Abstract

A method for obtaining a chemical concentration from a chemical composition and a fluid includes introducing the fluid through ports in a manifold diffuse member positioned adjacent a chemical composition and adjusting, with a fluid valve, characteristics of the flow of the fluid through the ports in the diffuser manifold to obtain and maintain a chemical concentration. The amount of liquid allowed through the ports modifies the turbulence of the liquid, thereby modifying the erosion rate of the chemical composition. An apparatus for adjusting characteristics of the flow of a fluid contacting a solid product to form a product chemistry includes a diffuser manifold having a manifold diffuse member comprising ports therethrough and a fluid valve for controlling the flow rate of a fluid moving through the plurality of ports and diverting the fluid through various flow paths.

First claim

What is claimed is:

1. An apparatus for adjusting characteristics of the flow of a fluid contacting a solid product to form a product chemistry comprising:
a diffuser manifold having a manifold diffuse member comprising:
a first side with ports therethrough; and
a second side having a first fluid path and a second fluid path determined by a flow geometry of the manifold diffuse member, the first fluid path and the second fluid path intersected by the ports; and

a fluid valve for controlling the flow rate of a fluid moving through the plurality of ports and having at least three configurations that allow for selectively orienting a flow of the fluid through, in a first configuration, a first flow path, a second flow path, and a third flow path; in a second configuration, the first flow path and the third flow path; and in a third configuration, a second flow path and the third flow path;
wherein the first flow path, the second flow path, and the third flow path are fluidly parallel with each another in the first configuration.

2. The apparatus of claim 1 wherein the fluid valve has a fourth configuration wherein the flow is permitted to move through only the third flow path.

3. The apparatus of claim 1 further comprising a means for selectively closing the third flow path.

4. The apparatus of claim 1 wherein fluid diverted through the first flow path travels through the first fluid path and fluid diverted through the second flow path travels through the second fluid path.

5. The apparatus of claim 1 wherein the fluid valve further comprises a static gasket to seal off the first flow path or the second flow path.

6. The apparatus of claim 1 wherein the fluid valve comprises an external component for driving rotation of an internal rotatable component.

7. The apparatus of claim 6 wherein the external component includes an indicator for indicating which flow paths are open or closed.

8. The apparatus of claim 6 wherein the rotatable component includes a rotary disc with holes therethrough, some of the apertures being plugged by valve seals.

9. The apparatus of claim 1 wherein the fluid valve further comprises a stationary component which attaches to a base to form at least a portion of an external structure of the fluid valve.

10. The apparatus of claim 9 wherein the stationary component comprises flow control cavities and raised surfaces where the fluid exits the flow control cavities.

11. The apparatus of claim 9 wherein the fluid valve comprises a static gasket for creating a watertight seal between the stationary component and the base.

12. The apparatus of claim 9 wherein the stationary component and the base are attached with a ratchet and a pawl.

13. The apparatus of claim 1 wherein the ports have varying diameters.

14. A dispenser configured to obtain a product chemistry from a product and a liquid comprising:
a housing;
a cavity within the housing for holding the product;
a liquid source adjacent the cavity for providing a liquid to contact the product to create a product chemistry; and
the apparatus of claim 1 .

15. The dispenser of claim 14 further comprising an outlet operatively connected to the cavity to dispense the product chemistry from the dispenser.

16. The dispenser of claim 14 wherein the diffuser manifold is removably secured within the dispenser.

17. A method for using the apparatus of claim 1 and obtaining a chemical concentration from a chemical composition and a fluid, said method comprising:
introducing the fluid through the ports in the manifold diffuse member positioned adjacent the chemical composition; and
adjusting, with the fluid valve, characteristics of the flow of the fluid through the ports in the diffuser manifold to obtain and maintain the chemical concentration;
wherein the amount of fluid allowed through the ports modifies the turbulence of the fluid, thereby modifying the erosion rate of the chemical composition.

18. The method of claim 17 wherein the characteristics of the flow include:
a. velocity,
b. pressure,
c. turbulence,
d. temperature,
e. flow rate,
f. vector, and/or
g. impingement.

19. The method of claim 18 wherein the step of adjusting characteristics of the flow comprises diverting the fluid through a first flow path, a second flow path, or a third flow path.

20. The method of claim 19 wherein fluid diverted through the first flow path travels through a first fluid path determined by a flow geometry of the manifold diffuse member and fluid diverted through the second flow path travels through a second fluid path determined by said flow geometry.
