Valve seal for reciprocating pump
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 component includes a body that defines a recess and includes a tapered sealing section. The sealing element includes a sealing surface and is configured to be positioned within the recess in an assembled configuration of the valve component. The sealing surface of the sealing element is coplanar to the tapered sealing section of the body in the assembled configuration.
1 . A valve component for a reciprocating pump, comprising:
a body comprising a tapered sealing section, a first linear section, a second linear section, and an arc extending between the first linear section and the second linear section to define a recess, wherein the first linear section is planar and extends radially inward from a lateral outer surface to the arc, the second linear section extends transverse to the first linear section to the arc, and the first linear section and the second linear section do not overlap with one another such that the recess lacks a cutout extending into the body; and
a sealing element configured to be positioned within the recess, wherein the sealing element comprises a sealing surface that is coplanar to the tapered sealing section of the body to form a valve sealing surface with the body in an assembled configuration of the valve component.
2 . The valve component of claim 1 , wherein the body comprises:
a first portion comprising the tapered sealing section; and
a second portion connected to the first portion, wherein the second portion is offset from the tapered sealing section to define the recess between the tapered sealing section and the second portion.
3 . The valve component of claim 2 , wherein the sealing element extends from the second portion to the tapered sealing section of the first portion to form the valve sealing surface with the tapered sealing section.
4 . The valve component of claim 2 , wherein the sealing element comprises an annular ring shape that surrounds the first portion.
5 . The valve component of claim 1 , wherein the second linear section extends obliquely to the tapered sealing section.
6 . The valve component of claim 1 , wherein the sealing element lacks a protrusion extending into the recess.
7 . The valve component of claim 1 , wherein the first linear section is approximately perpendicular to the lateral outer surface.
8 . The valve component of claim 1 , wherein the second linear section extends from the tapered sealing section to the arc.
9 . 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 tapered sealing section, a first linear section, a second linear section, and an arc extending between the first linear section and the second linear section to define a recess, wherein the first linear section is planar and extends radially inward from a lateral outer surface to the arc, the second linear section extends transverse to the first linear section to the arc, and the first linear section and the second linear section do not overlap with one another such that the recess lacks a cutout extending into the body; and
a sealing element secured to the body and comprising a second tapered sealing surface, wherein at least one of the tapered sealing section or the second tapered sealing surface is configured to abut the first tapered sealing surface of the valve seat in a closed position of the valve component.
10 . The valve assembly of claim 9 , wherein the body comprises:
a first portion comprising the tapered sealing section; and
a second portion offset from the tapered sealing section to define the recess between the tapered sealing section and the second portion, wherein the sealing element is positioned within the recess to secure to the body of the valve component.
11 . The valve assembly of claim 10 , wherein the tapered sealing section of the first portion is oriented at a first angle with respect to the second portion, the second tapered sealing surface of the sealing element is oriented at a second angle with respect to the second portion, and the first angle and the second angle are equal to one another.
12 . The valve assembly of claim 11 , wherein the tapered sealing section of the first portion and the second tapered sealing surface of the sealing element are coplanar to one another.
13 . The valve assembly of claim 12 , wherein the sealing element is composed of a compressible material such that compression of the sealing element causes the second tapered sealing surface of the sealing element to be oriented coplanar to the tapered sealing section of the first portion.
14 . The valve assembly of claim 10 , wherein the sealing element lacks a protrusion extending into the recess.
15 . The valve assembly of claim 10 , wherein the sealing element surrounds the first portion.
16 . The valve assembly of claim 9 , wherein both the tapered sealing section and the second tapered sealing surface are configured to abut the first tapered sealing surface of the valve seat in the closed position of the valve component.
17 . The valve assembly of claim 9 , wherein the valve seat comprises a lateral surface and an arcuate portion extending from the lateral surface to the first tapered sealing surface.
18 . The valve assembly of claim 9 , wherein the second linear section and the tapered sealing section are oriented at an obtuse angle with one another.
19 . The valve assembly of claim 18 , wherein the first linear section and the second linear section form an acute angle with one another.
20 . The valve assembly of claim 9 , wherein the first linear section is approximately perpendicular to the lateral outer surface.
