Abstract
Embodiments of the present disclosure relate to a valve assembly that includes a valve configured to adjust a flow of fluid through a valve body of the valve assembly, an actuator configured to drive rotation of the valve, a gear assembly having a first planetary gear assembly and a second planetary gear assembly, where the first planetary gear assembly is coupled to the actuator, and where the second planetary gear assembly is coupled to the valve, and an override assembly coupled to the second planetary gear assembly, where the override assembly is configured to drive rotation of the valve independent of the actuator and without disengaging the actuator from the gear assembly.
Claims18
A valve assembly, comprising:
- a valve configured to adjust a flow of fluid through a valve body of the valve assembly;
- an actuator configured to drive rotation of the valve;
- a gear assembly comprising a first planetary gear assembly and a second planetary gear assembly, wherein the first planetary gear assembly is coupled to the actuator, and wherein the second planetary gear assembly is coupled to the valve;
- and
- an override assembly comprising an external gear that is at least partially external to a housing of the second planetary gear, wherein the housing comprises an opening configured to enable the external gear to directly couple to the second planetary gear assembly, wherein the override assembly is configured to drive rotation of the valve independent of the actuator and without disengaging the actuator from the gear assembly, and wherein the housing comprises an additional opening configured to enable at least a portion of a ring gear of the second planetary gear assembly to extend outward from the housing through the additional opening.
2 more elements
A system, comprising:
- a flow path configured to convey a fluid flow in a mineral extraction system;
- a valve disposed along the flow path and configured to adjust a flow rate of the fluid flow through a valve body of the valve;
- an actuator configured to drive rotation of the valve;
- a gear assembly comprising a first planetary gear assembly and a second planetary gear assembly, wherein the first planetary gear assembly is coupled to the actuator, and wherein the second planetary gear assembly is coupled to the valve;
- an override assembly comprising an external gear that is at least partially external to a housing of the second planetary gear assembly, wherein the housing comprises an opening configured to enable the external gear to directly couple to the second planetary gear assembly, wherein the override assembly is configured to drive rotation of the valve independent of the actuator and without disengaging the actuator from the gear assembly, and wherein the housing comprises an additional opening configured to enable at least a portion of a ring gear of the second planetary gear assembly to extend outward from the housing through the additional opening;
- and
- a controller configured to receive feedback from a sensor disposed along the flow path, and wherein the controller is configured send a signal to the actuator or the override assembly based at least on the feedback.
4 more elements
A method, comprising:
- detecting an event when an actuator of a valve assembly fails to adjust a position of a valve of the valve assembly, wherein the valve assembly comprises a first planetary gear assembly and a second planetary gear assembly, and wherein the actuator is coupled to the first planetary gear assembly;
- actuating an override assembly coupled to the second planetary gear assembly upon detection of the event;
- and
- driving rotation of the second planetary gear assembly using an external gear of the override assembly to adjust the position of the valve, wherein the override assembly adjusts the position of the valve independent of the actuator and without disengaging the actuator from the gear assembly, wherein the external gear is at least partially external to a housing of the second planetary gear assembly, wherein the housing comprises an opening configured to enable the external gear to directly couple to the second planetary gear, and wherein the housing comprises an additional opening configured to enable at least a portion of a ring gear of the second planetary gear assembly to extend outward from the housing through the additional opening.
