Abstract

Fluid flow control devices comprise a body including a central aperture extending along a longitudinal axis therethrough and a plurality of channels extending from an outer sidewall of the body to an inner sidewall of the body. At least one first channel may intersect at least one other channel. Fluid flow control systems, methods of forming fluid flow control devices, and methods of flowing a fluid through a fluid flow control device are also disclosed.

Claims

1. A fluid flow control device, comprising:

a body comprising a central aperture therethrough extending along a longitudinal axis thereof;

at least one first channel extending from an outer sidewall of the body to an inner sidewall of the body at a first continuous, uniform direction; and

at least one second channel extending from the outer sidewall of the body to the inner sidewall of the body at a second continuous, uniform direction and intersecting the at least one first channel, wherein two intersecting channels fit simultaneously through an area having an approximate width of a single channel, wherein the at least one first channel and the at least one second channel extend at least substantially linearly from the outer sidewall to the inner sidewall of the body.

2. The fluid flow control device of claim 1, wherein the body comprises a plurality of disks stacked adjacent to one another.

3. The fluid flow control device of claim 1, wherein the at least one first channel intersects a plurality of other channels.

4. The fluid flow control device of claim 3, wherein at least some of the angle of intersections between the at least one first channel and the plurality of other channels are different.

5. A fluid flow control device, comprising:

a body comprising a plurality of disks coupled axially together along a longitudinal axis, wherein at least one disk of the plurality of disks comprises a plurality of grooves in a surface thereof, each groove of the plurality of grooves extending from an outer diameter to an inner diameter of the at least one disk, wherein at least one groove of the plurality of grooves intersects one or more other grooves of the plurality of grooves at corresponding one or more stages, each stage of the corresponding one or more stages being configured to contract fluid flow by forcing fluid flowing through two intersecting grooves of the plurality of grooves to fit simultaneously through the stage, the at least one groove of the plurality of grooves being bounded by parallel groove sidewalls extending smoothly and continuously from the outer diameter to the inner diameter of the at least one disk, wherein the at least one groove has discontinuities only at the one or more stages.

6. The fluid flow control device of claim 5, wherein each groove of the plurality of grooves intersects at least one other groove of the plurality of grooves.

7. The fluid flow control device of claim 6, wherein each groove of the plurality of grooves intersects two or more other grooves of the plurality of grooves.

8. The fluid flow control device of claim 5, wherein the plurality of disks comprises a material selected from the group of materials consisting of metal, metal alloy, or ceramic.

9. A fluid flow control system, comprising:

a fluid inlet; and

a fluid flow control device positioned in relation to the fluid inlet so that a fluid passing from the fluid inlet flows therethrough, the fluid flow control device comprising;

at least one first channel having parallel channel sidewalls extending smoothly and directly from an outer sidewall of a body to an inner sidewall of a central aperture extending through the body; and

at least one second channel having parallel channel sidewalls extending smoothly and directly from the outer sidewall of the body to the inner sidewall of the body and intersecting the at least one first channel, wherein at least two intersecting channels fit simultaneously through an area having an approximate width of a single channel.

10. The fluid flow control system of claim 9, further comprising:

a valve body comprising a plug chamber positioned between the fluid inlet and a fluid outlet;

a plug head disposed in the plug chamber; and

wherein the fluid flow control device is configured as a seat retainer positioned in the plug chamber.

11. The fluid flow control system of claim 9, wherein the fluid flow control device is coupled to the fluid inlet at one longitudinal end and is closed at an opposing longitudinal end.

12. The fluid flow control system of claim 9, wherein the body comprises a plurality of substantially planar disks stacked adjacent to one another.

13. The fluid flow control system of claim 9, wherein the at least one first channel and the at least one second channel extend substantially linearly from the outer sidewall to the inner sidewall of the body.

14. A method of flowing a fluid through a fluid flow control device, comprising:

flowing a fluid through a first channel that extends along a first single straight line from an outer surface of a body to an inner surface of an aperture extending through the body;

flowing a fluid through at least one second channel that extends along a second single straight line from the outer surface of the body to the inner surface of the aperture, the at least one second channel intersecting the first channel, the first channel and the at least one second channel being bounded by parallel channel sidewalls extending smoothly and continuously from the outer surface of the body to the inner surface of the aperture; and

impinging the fluid flowing through the channel into the fluid flowing through the at least one second channel, wherein the intersecting channels fit simultaneously through an area having an approximate width of a single channel.
