Abstract

A valve component utilized in a fluid end assembly of a high pressure reciprocating pump includes a valve body and a sealing element. The valve body defines a recess configured to receive the sealing element. The sealing element is composed of a fiber reinforced material. The valve component is configured to be disposed in a closed position with respect to a valve seat such that a sealing surface of the sealing element engages with a corresponding sealing surface of the valve seat in the closed position.

First claim

What is claimed is:

1. A valve component for a reciprocating pump, the valve component comprising:
a body comprising a base portion defining a recess; and
a fiber reinforced sealing element configured to be positioned within the recess to form a valve sealing surface with the body, wherein the fiber reinforced sealing element comprises a plurality of fabric panel layers stacked against one another, the plurality of fabric panel layers extending between a first surface that abuts the base portion of the body and a second surface, opposite the first surface, that forms at least a portion of the valve sealing surface, wherein the plurality of fabric panel layers are each infused with elastomeric material.

2. The valve component of claim 1 , wherein the base portion of the body comprises:
a first member comprising a tapered sealing section; and
a second member connected to the first member, wherein the second member is offset from the tapered sealing section to define the recess between the tapered sealing section and the second member.

3. The valve component of claim 2 , wherein the fiber reinforced sealing element extends from the second member to the tapered sealing section of the first member to form the valve sealing surface with the tapered sealing section.

4. The valve component of claim 2 , wherein the fiber reinforced sealing element comprises an annular ring shape that surrounds the first member.

5. The valve component of claim 2 , wherein the second surface of the fiber reinforced sealing element comprises a fiber reinforced sealing surface, and the fiber reinforced sealing surface and the tapered sealing section cooperatively form the valve sealing surface.

6. The valve component of claim 1 , wherein each fabric panel layer of the plurality of fabric panel layers is composed of a woven fabric comprising a weave of fibers, and the woven fabric is overmolded with the elastomeric material to infuse the plurality of fabric panel layers with the elastomeric material.

7. The valve component of claim 1 , wherein each fabric panel layer of the plurality of fabric panel layers is composed of a woven fabric comprising a weave of fibers, and the woven fabric is applied to a portion of the elastomeric material to infuse the plurality of fabric panel layers with the elastomeric material.

8. The valve component of claim 1 , wherein fibers of fabric forming the plurality of fabric panel layers reinforce the elastomeric material.

9. The valve component of claim 1 , wherein the plurality of fabric panel layers extends along a third surface that abuts the body, the third surface connecting the first surface and the second surface to one another.

10. The valve component of claim 1 , wherein each fabric panel layer of the plurality of fabric panel layers is composed of a woven fabric comprising a weave of fibers extending radially outward from a central axis extending through the fiber reinforced sealing element.

11. The valve component of claim 1 , wherein fabric panel layers of the plurality of fabric panel layers are adhered to one another.

12. A method of manufacturing a valve component, the method comprising:
forming a plurality of fabric panel layers stacked against one another and extending between a first surface and a second surface, opposite the first surface;
overmolding elastomeric material onto the plurality of fabric panel layers to infuse the plurality of fabric panel layers with the elastomeric material to provide a fiber reinforced sealing element; and
positioning the fiber reinforced sealing element in a recess of a body of the valve component by abutting the first surface with the body to form at least a portion of a valve sealing surface with the second surface.

13. The method of claim 12 , comprising orienting a single fabric panel in a helical configuration to form the plurality of fabric panel layers stacked against one another.

14. The method of claim 12 , comprising stacking a plurality of separate fabric panels to form the plurality of fabric panel layers stacked against one another.

15. The method of claim 12 , comprising trimming the fiber reinforced sealing element positioned in the recess of the body of the valve component to align the second surface with a sealing section of the body of the valve component, to align an outer perimeter of the fiber reinforced sealing element with an outer perimeter of the body of the valve component, or both.

16. The method of claim 12 , comprising compression molding the fiber reinforced sealing element onto the body of the valve component to adhere the plurality of fabric panel layers to one another and to the body.

17. A valve assembly, comprising:
a valve seat defining a bore and comprising a first tapered sealing surface; and
a valve component comprising:
a body comprising a sealing section; and
a fiber reinforced sealing element secured to the body and surrounding the sealing section of the body, wherein a second tapered sealing surface of the fiber reinforced sealing element abuts against the first tapered sealing surface of the valve seat in a closed position of the valve component, and the fiber reinforced sealing element comprises a plurality of fabric panel layers stacked against one another, the plurality of fabric panel layers extending between a first surface in abutment with the body and the second tapered sealing surface, wherein the plurality of fabric panel layers are each infused with elastomeric material.

18. The valve assembly of claim 17 , wherein the valve component comprises:
a first member comprising the sealing section; and
a second member offset from the sealing section to define a recess between the sealing section and the second member, wherein the plurality of fabric panel layers extends from the second member to the sealing section.

19. The valve assembly of claim 17 , wherein the elastomeric material is secured to the body, the elastomeric material comprises a valve engaging surface configured to engage with the body, and the fiber reinforced sealing element comprises a woven fabric of fibers applied to the valve engaging surface.

20. The valve assembly of claim 17 , wherein a woven fabric forming the plurality of fabric panel layers is infused with the elastomeric material.
