Abstract

A multipurpose valve tool is provided. The multipurpose valve tool includes multiple flow control discs, a retention ring, and a valve key. The flow control discs are configured to be installed within a valve body of a valve assembly to modulate a flow of fluid through an outlet port of the valve body. The retention ring is configured to retain the flow control discs on a component of the valve assembly when the flow control discs are not installed within the valve body. The valve key includes a first end configured to engage an installation feature in a retention fastener for one of the flow control discs. The flow control discs, the retention ring, and the valve key are detachably coupled to each other.

First claim

What is claimed is:

1. A multipurpose valve tool comprising:
a plurality of flow control discs configured to be installed within a valve body of a valve assembly to modulate a flow of fluid through at least one outlet port of the valve body;
a retention ring configured to retain the plurality of flow control discs on a component of the valve assembly when the plurality of flow control discs are not installed within the valve body; and
a valve key having a first end configured to engage an installation feature in a retention fastener for one of the plurality of flow control discs;
wherein the plurality of flow control discs, the retention ring, and the valve key are detachably coupled to each other.

2. The multipurpose valve tool of claim 1 , wherein the tool is formed via an injection molding process.

3. The multipurpose valve tool of claim 1 , wherein the component of the valve assembly is at least one of the valve body or an actuator.

4. The multipurpose valve tool of claim 1 , wherein the valve key further comprises a second end having a cutout region, the cutout region configured to couple to a valve stem of the valve assembly in order to rotate a valve member of the valve assembly.

5. The multipurpose valve tool of claim 1 , wherein the installation feature is a recess on a face of the retention fastener.

6. The multipurpose valve tool of claim 1 , wherein each of the plurality of flow control discs has a unique central bore diameter.

7. The multipurpose valve tool of claim 1 , wherein each of the plurality of flow control discs has an identical outer diameter.

8. The multipurpose valve tool of claim 1 , wherein the retention fastener has a threaded outer diameter portion, the threaded outer diameter portion configured to be threadably coupled to an outlet port of the valve body.

9. The multipurpose valve tool of claim 1 , wherein each of the plurality of flow control discs has a flow coefficient indicator feature identifying a flow rate that can be achieved when the flow control disc is installed in the outlet port of the valve body.

10. The multipurpose valve tool of claim 9 wherein the flow coefficient indicator feature includes text expressing a flow coefficient of the flow control disc in at least one of metric units Kv or imperial units Cv.

11. The multipurpose valve tool of claim 1 , wherein the retention ring is substantially U-shaped and terminates at a first curved end and a second curved end, the first curved end and the second curved end configured to be intertwined.

12. The multipurpose valve tool of claim 1 , wherein the first end of the valve key is substantially cross-shaped.

13. A multipurpose valve tool comprising:
a plurality of flow control discs configured to be installed within a valve body of a valve assembly and to modulate a flow of fluid through at least one outlet port of the valve body;
a retention ring comprising a substantially U-shaped portion terminating at a first curved end and a second curved end, the first curved end and the second curved end configured to be intertwined to retain the plurality of flow control discs on a component of the valve assembly when the plurality of flow control discs are not installed within the valve body;
a valve key having a cutout region configured to couple to a valve stem of the valve assembly in order to rotate a valve member of the valve assembly; and
wherein the plurality of flow control discs, the retention ring, and the valve key are formed as an integrated part and detachably coupled to each other.

14. The multipurpose valve tool of claim 13 , wherein the integrated part is fabricated from at least one of a blue plastic injection molded material or a red plastic injection molded material.

15. The multipurpose valve tool of claim 13 , wherein each of the plurality of flow control discs has a flow coefficient indicator feature identifying a flow rate that can be achieved when the flow control disc is installed in the outlet port of the valve body.

16. A system for controlling fluid flow, the system comprising:
a valve assembly comprising:
a valve body having a valve chamber and plurality of ports into the valve chamber;
a valve member controllably movable relative to the valve body and configured to modulate fluid flow through the valve assembly; and
a valve stem coupled to the valve member and extending from the valve body;

an actuator comprising a motor and a drive device, the drive device driven by the motor and coupled to the valve stem for driving the valve member between multiple positions;
a plurality of flow control discs configured to be installed within the valve body to modulate a flow of fluid through at least one outlet port of the valve body, each flow control disc comprising a central bore having a unique diameter;
a retention ring configured to be inserted through the central bore of each of the plurality of flow control discs when the plurality of flow control discs are not installed within the valve body in order to retain the plurality of flow control discs on the actuator.

17. The system of claim 16 , wherein the retention ring is further configured to retain a valve key, the valve key having a cutout region configured to couple to the valve stem in order to rotate the valve member.

18. The system of claim 17 , wherein the valve key is further configured to terminate in a substantially cross-shaped end opposite the cutout region, the substantially cross-shaped end configured to engage an installation feature on a retention fastener for one of the plurality of flow control discs.

19. The system of claim 16 , wherein the retention ring is substantially U-shaped and terminates at a first curved end and a second curved end, the first curved end and the second curved end configured to be intertwined.

20. The system of claim 16 , wherein the retention ring is further configured to be inserted through an aperture in the actuator.
