Abstract

Apparatus, systems and methods for implementing flow cages and flow cage assemblies in association with high pressure fluid flows and fluid valves are provided. Flow cages and flow assemblies are provided to dissipate the energy of a fluid flow, such as by reducing fluid flow pressure and/or fluid flow velocity. In some embodiments the dissipation of the fluid flow energy is adapted to reduce erosion, such as from high-pressure jet flows, to reduce cavitation, such as by controllably increasing the flow area, and/or to reduce valve noise associated with pressure surge.

Claims

1. A flow cage assembly comprising:

at least one flow cage body having a planar portion disposed along a first axis and a non-planar portion disposed along a second axis that is at an out-of-plane angle to said first axis, each at least one flow cage body having at least one inlet and at least one outlet, wherein the at least one outlet is configured to be within the non-planar portion, and defining at least one flow path therebetween, such that there is fluid communication through said flow cage body through the at least one flow path;

wherein each of the at least one inlets defines a first fluid flow direction and each of the at least one outlets defines a second fluid flow direction, and each of the at least one flow paths is configured to redirect an incoming fluid flow in at least one redirected fluid flow direction that is angled to the first fluid flow direction at least once prior to interconnecting said incoming fluid flow to the outlet.

2. The flow cage assembly of claim 1, wherein the fluid flow is redirected at least in a redirected fluid flow direction that is out-of-plane with the first fluid flow direction.

3. The flow cage assembly of claim 1, wherein the flow path redirects the fluid flow at least in a first redirected fluid flow direction that is in-plane with the first fluid flow direction and in a second redirected fluid flow direction that is out-of-plane with the first fluid flow direction before interconnecting the incoming fluid flow to the outlet.

4. The flow cage assembly of claim 1, wherein the second fluid flow direction is in-line with an external fluid flow into which the at least one outlet communicates.

5. The flow cage assembly of claim 1, wherein the second fluid flow direction is counter to an external fluid flow into which the at least one outlet communicates.

6. The flow cage assembly of claim 1, comprising at least two inlets and a plurality of outlets, wherein each inlet is interconnected to said plurality of outlets.

7. The flow cage assembly of claim 1, comprising at least two flow cage bodies, the flow cage bodies being cooperatively stackable.

8. The flow cage assembly of claim 1, wherein the flow area of the at least one flow path is one of either constricted or dilated between the at least one inlet and the at least one outlet.

9. The flow cage assembly of claim 1, wherein the flow path is formed from at least one of the following, a single path channel or an array of angular body flow features, the angular body flow features having shapes having a plurality of faces and vertices selected from the group consisting of quadrilaterals, triangles, hexagons, and octagons.

10. A valve comprising:

a valve body having a valve inlet in fluid communication with a first external fluid passage and a valve outlet in fluid communication with a second external fluid passage and a valve gate disposed therebetween for opening and closing the fluid communication therebetween;

at least one flow cage assembly disposed in fluid communication with said valve body, the flow cage assembly comprising at least one flow cage body having a planar portion disposed along a first axis and a non-planar portion disposed along a second axis at an out-of-plane angle to said first axis, each at least one flow cage body having at least one inlet in fluid communication with the valve gate and at least one outlet, wherein the at least one outlet is configured to be within the non-planar portion and in fluid communication with the valve outlet, the flow cage body further defining at least one flow path between said at least one inlet and at least one outlet;

wherein each of the at least one inlets defines a first fluid flow direction and each of the at least one outlets defines a second fluid flow direction, and each of the at least one flow paths is configured to redirect an incoming fluid flow in at least one redirected fluid flow direction that is angled to the first fluid flow direction at least once prior to interconnecting said incoming fluid flow to the outlet.

11. The valve of claim 10, wherein the fluid flow is redirected at least in a redirected fluid flow direction that is out-of-plane with the first fluid flow direction.

12. The valve of claim 10, wherein the flow path redirects the fluid flow at least in a first redirected fluid flow direction that is in-plane with the first fluid flow direction and in a second redirected fluid flow direction that is out-of-plane with the first fluid flow direction before interconnecting the incoming fluid flow to the outlet.

13. The valve of claim 10, wherein the second fluid flow direction is counter to the fluid flow direction in the second external fluid passage.

14. The valve of claim 10, wherein the flow cage assembly comprises at least two flow cage bodies, the flow cage bodies being cooperatively stackable.

15. The valve of claim 10, wherein the flow area of the at least one flow path is one of either constricted or dilated between the at least one inlet and the at least one outlet.
