Abstract
Valve assemblies and related pumps and methods may include an insert disposed in an internal flow path of a casing where an outer surface of the insert is fixedly engaged with an inner surface the casing with fluid sealing. The insert includes protrusions, each individually extending into the internal flow path of the casing and converging at an apex of the insert to define a cage in which the restriction element is configured to move axially through the internal flow path.
Claims20
A valve assembly comprising:
- a restriction element;
- a casing defining an internal flow path through the casing, the casing comprising at least one axial connection for connecting with a component of a fluid-handling device;
- an insert disposed in the internal flow path through the casing, an outer surface of the insert being fixedly engaged with an inner surface the casing, the insert comprising at least three axially extending protrusions, each of the at least three axially extending protrusions individually extending inward into the internal flow path of the casing and converging with at least another of the at least three axially extending protrusions at an apex of the insert to define a cage in which the restriction element is configured to move axially through the internal flow path;
- and
- a seat positioned opposite to the apex of the insert to contain the restriction element in the insert;
- wherein:
- in an open position, the restriction element is configured to be displaced toward the apex of the insert to enable fluid flow through the internal flow path and through openings defined between the at least three axially extending protrusions;
- and
- in a closed position, the restriction element is configured to engage with the seat to restrict fluid flow through the internal flow path.

A downhole pump comprising:
- a barrel comprising an interior cavity;
- a plunger;
- a valve rod mechanically connected to the plunger and configured to drive the plunger within the interior cavity of the barrel;
- and
- at least one valve assembly comprising:
- a restriction element;
- a casing coupled to the barrel as a standing valve or to the plunger as a traveling valve, the casing defining an internal flow path through the casing that is in communication with the interior cavity of the barrel;
- and
- an insert having an outer surface that is fixedly engaged with an inner surface the casing, the insert comprising at least two ribs, each individually extending from a base portion of the insert to an apex of the insert where each of the at least two ribs converge to define a cage in which the restriction element is configured to move axially through the internal flow path between the apex and a seat positioned in the casing axially opposite the apex;
- wherein, in an open position, the restriction element is configured to be displaced toward the apex of the insert to enable fluid flow through the internal flow path of the casing and through openings defined between the at least two ribs;
- and
- wherein, in a closed position, the restriction element is configured to restrict fluid flow through the internal flow path.

A method of forming a valve assembly, the method comprising:
- positioning a restriction element within a casing between an insert and a seat,
- positioning the restriction element, the insert, and the seat in an internal flow path through the casing;
- fixedly engaging an outer surface of the insert with an inner surface the casing via an interference fit;
- defining openings in the internal flow path with at least three protrusions of the insert that extend through the internal flow path of the casing and converge with at least another of the at least three protrusions at an apex of the insert to define a cage in which the restriction element is configured to move axially through the internal flow path;
- in an open position, enabling the restriction element to be displaced toward the apex of the insert to enable fluid flow through the internal flow path and through openings defined between the at least three protrusions;
- and
- in a closed position, enabling the restriction element to engage with the seat to restrict fluid flow through the internal flow path.
