Abstract

Embodiments of the present disclosure are directed toward a choke valve system including a choke valve body and a plurality of choke trims. The plurality of choke trims comprises a plug and cage choke trim, an external sleeve choke trim, and a drilling choke trim, wherein the drilling choke trim is configured to enable a fluid flow rate greater than the plug and cage choke trim and the external sleeve choke trim, and wherein each of the plurality of choke trims is configured to be mutually exclusively secured within the choke valve body.

First claim

The invention claimed is:

1. A choke valve system, comprising:
a choke valve body having a chamber;
a bonnet configured to couple with the choke valve body; and
a plurality of choke trims, wherein the plurality of choke trims are different choke trim types,
wherein each of the plurality of choke trims is configured to be mutually exclusively secured within the chamber in the choke valve body, and the bonnet closes an opening over the chamber and secures one of the plurality of choke trims in the chamber.

2. The choke valve system of claim 1 , wherein the different choke trim types of the plurality of choke trims, comprise:
a plug and cage choke trim;
an external sleeve choke trim; and
a drilling choke trim, wherein the drilling choke trim is configured to enable a larger particle tolerance than the plug and cage choke trim and the external sleeve choke trim.

3. The choke valve system of claim 1 , wherein the bonnet is coupled to the choke valve body with a plurality of fasteners.

4. The choke valve system of claim 3 , wherein the plurality fasteners are oriented along an axis of the choke valve body.

5. The choke valve system of claim 1 , wherein at least one of the plurality of choke trims is configured to be retained between a choke trim seat recess and the bonnet with at least one additional retaining feature.

6. The choke valve system of claim 5 , wherein the additional retaining feature comprises one or more retaining elements positioned between the bonnet and the at least one of the plurality of choke trims.

7. The choke valve system of claim 1 , wherein each of the plurality of choke trims has approximately the same overall length and approximately the same outer diameter.

8. The choke valve system of claim 1 , wherein the choke valve body comprises a production choke body designed for production choke trims.

9. The choke valve system of claim 1 , comprising an actuator configured to adjust a position of the one of the plurality of choke trims secured in the chamber.

10. The choke valve system of claim 9 , comprising a controller communicatively coupled to the actuator, wherein the controller is configured to control the actuator to adjust a flow by adjusting the position of the one of the plurality of choke trims based on an identified type of the one of the plurality of choke trims positioned within the choke valve body.

11. The choke valve system of claim 10 , wherein the controller is configured to regulate operation of the actuator based on a type of additional equipment being used with the choke valve system, based on operating conditions of a fluid-handling system having the choke valve system, or a combination thereof.

12. The choke valve system of claim 1 , wherein at least one trim of the plurality of choke trims is configured to be secured within the choke valve body with an axial end of the at least one trim disposed axially against a choke trim seat recess.

13. The choke valve system of claim 12 , wherein the at least one trim of the plurality of choke trims is configured to be secured within the choke valve body with a first portion of the at least one trim disposed axially against the choke trim seat recess and a second portion of the at least one trim extending axially into a central bore of the choke valve body beyond the choke trim seat recess.

14. The choke valve system of claim 1 , wherein at least one trim of the plurality of choke trims comprises an outer member disposed about an inner member along an axis, and the inner member extends at least axially to or beyond an axial end of the outer member.

15. The choke valve system of claim 14 , wherein the inner member comprises a plug and the outer member comprises an outer sleeve or outer cage.

16. The choke valve system of claim 14 , wherein the inner member comprises an inner sleeve or inner cage and the outer member comprises an outer sleeve or outer cage.

17. The choke valve system of claim 1 , wherein one of the different choke trim types of the plurality of choke trims comprises a silencer or labyrinth choke trim.

18. The choke valve system of claim 1 , wherein at least part of each trim of the plurality of choke trims is configured to be directly retained by the bonnet.

19. The choke valve system of claim 1 , wherein the bonnet is configured to be fastened to a side wall of the choke valve body.

20. The choke valve system of claim 1 , wherein the bonnet is configured to couple with the choke valve body after the one of the plurality of choke trims is installed within the choke valve body.

21. The choke valve system of claim 1 , comprising a shaft extending through the bonnet to the one of the plurality of choke trims mutually exclusively secured within the choke valve body, wherein a manual actuator is coupled to the shaft.

22. The choke valve system of claim 1 , wherein a first one of the plurality of choke trims terminates at an axial end that abuts axially against a choke trim seat recess when installed in the chamber in the choke valve body, and a second one of the plurality of choke trims has a first portion disposed axially against the choke trim seat recess and a second portion extending axially into a central bore of the choke valve body beyond the choke trim seat recess when installed in the chamber in the choke valve body.

23. A choke valve system, comprising:
a choke valve body;
a plurality of choke trims, comprising at least two of:
a plug and cage choke trim;
an external sleeve choke trim; or
a drilling choke trim, wherein the drilling choke trim is configured to enable a larger particle tolerance than the plug and cage choke trim and the external sleeve choke trim,

wherein each of the plurality of choke trims is configured to be mutually exclusively secured within the choke valve body;
an actuator configured to adjust a flow by adjusting a position of one choke trim of the plurality of choke trims mutually exclusively secured within the choke valve body; and
a controller communicatively coupled to the actuator, wherein the controller is configured to control the actuator to adjust the flow by adjusting the position of the one choke trim based on an identified type of the one choke trim positioned within the choke valve body.

24. A choke valve system, comprising:
a choke valve body;
an opening in the choke valve body, wherein the opening is configured to mutually exclusively support one of a plurality of choke trims, comprising:
a first choke trim;
a second choke trim; and
a third choke trim, wherein the first, second, and third choke trims are different types of choke trims, wherein the first, second, and third choke trims have different particle tolerances;

an actuator configured to adjust a flow by adjusting a position of one choke trim of the plurality of choke trims mutually exclusively secured within the choke valve body; and
a controller communicatively coupled to the actuator, wherein the controller is configured to control the actuator to adjust the flow by adjusting the position of the one choke trim based on an identified type of the one choke trim positioned within the choke valve body, wherein the identified type is one of the different types of choke trims.

25. A choke valve system, comprising:
a choke valve body having a chamber; and
a plurality of choke trims, wherein the plurality of choke trims are different choke trim types,
wherein the choke valve body and the plurality of ch
