Abstract
A choke gate valve includes a housing that defines a fluid bore and a gate with multiple throttling orifices. The gate is configured to move within the housing between a first throttle position in which the gate extends across the fluid bore to position a first throttling orifice of the multiple throttling orifices in the fluid bore to throttle a fluid flow through the fluid bore and a second throttle position in which the gate extends across the fluid bore to position a second throttling orifice of the multiple throttling orifices in the fluid bore to throttle the fluid flow through the fluid bore.
Claims18
A choke gate valve, comprising:
- a housing that defines a fluid bore;
- and
- a gate comprising a plurality of throttling orifices, wherein the gate is configured to move within the housing between a first throttle position in which the gate extends across the fluid bore to position a first throttling orifice of the plurality of throttling orifices in the fluid bore to throttle a fluid flow through the fluid bore and a second throttle position in which the gate extends across the fluid bore to position a second throttling orifice of the plurality of throttling orifices in the fluid bore to throttle the fluid flow through the fluid bore, wherein the gate comprises a full bore orifice that comprises an inner diameter that corresponds to respective inner diameters of the fluid bore, and wherein the gate is configured to move within the housing to align the full bore orifice with the fluid bore to enable a full flow of the fluid flow.
A choke gate valve system, comprising:
- a housing that defines a fluid bore;
- a gate comprising a plurality of throttling orifices, wherein the gate is configured to move within the housing between a first throttle position in which the gate extends across the fluid bore to position a first throttling orifice of the plurality of throttling orifices in the fluid bore to throttle a fluid flow through the fluid bore and a second throttle position in which the gate extends across the fluid bore to position a second throttling orifice of the plurality of throttling orifices in the fluid bore to throttle the fluid flow through the fluid bore, wherein the gate comprises a full bore orifice that comprises an inner diameter that corresponds to respective inner diameters of the fluid bore, and wherein the gate is configured to move within the housing to align the full bore orifice with the fluid bore to enable a full flow of the fluid flow;
- and
- an actuator configured to drive the gate to move within the housing to selectively align one or more throttling orifices of the plurality of throttling orifices with the fluid bore.
