Adjustable bi-directional throttling choke valve
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.
1 . 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.
2 . The choke gate valve of claim 1 , wherein the first throttling orifice and the second throttling orifice comprise different sizes.
3 . The choke gate valve of claim 1 , wherein the first throttling orifice and the second throttling orifice comprise different shapes.
4 . The choke gate valve of claim 1 , wherein the gate comprises a solid portion, and the gate is configured to move within the housing to a closed position in which the solid portion of the gate extends across the fluid bore to shut off the fluid flow through the fluid bore.
5 . The choke gate valve of claim 1 , wherein each of the plurality of throttling orifices is configured to operate as a positive bean when exposed to the fluid flow in the fluid bore.
6 . The choke gate valve of claim 1 , wherein the gate is configured to move within the housing to an additional throttle position in which the gate extends across the fluid bore to cover a portion of the first throttling orifice of the plurality of throttling orifices with annular seats to thereby expose only a remaining portion of the first throttling orifice to the fluid bore to throttle the fluid flow through the fluid bore such that the choke gate valve operates as a variable orifice device.
7 . The choke gate valve of claim 1 , wherein the first throttling orifice and the second throttling orifice are arranged to enable the fluid flow to continue during a transition from the first throttle position to the second throttle position.
8 . The choke gate valve of claim 1 , wherein the choke gate valve is a bi-directional choke gate valve that is configured to throttle the fluid flow in either direction through the fluid bore.
9 . The choke gate valve of claim 1 , wherein the gate comprises a ductile metal material.
10 . The choke gate valve of claim 9 , wherein the gate is configured to move within the housing to a closed position to operate as a shutdown valve in response to conditions of the fluid flow.
11 . The choke gate valve of claim 1 , wherein the plurality of throttling orifices comprise tungsten carbides, ceramics, industrial diamond, or any combination thereof.
12 . The choke gate valve of claim 1 , comprising an upstream annular seat and a downstream annular seat, wherein the upstream annular seat, the downstream annular seat, or both comprise tungsten carbides, ceramics, industrial diamond, or any combination thereof.
13 . The choke gate valve of claim 1 , comprising annular seats, wherein mating surfaces of the gate and the annular seats comprise tungsten carbides, ceramics, industrial diamond, or any combination thereof.
14 . 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.
15 . The choke gate valve system of claim 14 , comprising a controller configured to instruct the actuator to drive the gate to move within the housing based on a user input, sensor data, or both.
16 . The choke gate valve system of claim 14 , wherein the plurality of throttling orifices comprises the first throttling orifice with a first size and the second throttling orifice with a second size that is different than the first size.
17 . The choke gate valve system of claim 16 , wherein the plurality of throttling orifices comprises a third throttling orifice with a third size that is the same as the first size.
18 . The choke gate valve system of claim 14 , wherein the plurality of throttling orifices comprises the first throttling orifice with a first shape and the second throttling orifice with a second shape that is different than the first shape.
