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.
Claims20
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.
A choke gate valve system, comprising:
- a housing that defines a fluid bore;
- a gate comprising a plurality of throttling orifices;
- 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.
A method of operating a choke gate valve system, the method comprising:
- adjusting a gate within a housing to a first throttle position to align a first throttling orifice of the gate with a fluid bore to throttle a fluid flow through the fluid bore;
- and
- adjusting the gate within the housing to a second throttle to align a second throttling orifice of the gate with the fluid bore to throttle the fluid flow through the fluid bore.
