Abstract

A fluid routing plug for use with a fluid end section. The fluid end section being one of a plurality of fluid end sections making up a fluid end side of a high pressure pump. The fluid routing plug is installed within a horizontal bore formed in a fluid end section and is configured to route fluid between an intake and discharge bore. The fluid routing plug comprises a plurality of first and second fluid passages. The first and second passages do not intersect and are offset from one another. The first fluid passages are configured to direct fluid delivered to the horizontal bore from intake bores towards a reciprocating plunger. The second fluid passages are configured to direct fluid pressurized by the plunger towards a discharge bore.

First claim

1 . An apparatus, comprising:
a fluid routing plug, comprising:
a body having an axially blind bore formed therein;
a first surface comprising a tapered wall, at least a portion of the tapered wall configured to engage a valve body;
an opposed second surface;
an outer intermediate surface joining the first and second surfaces;
a plurality of first passages joining a plurality of first openings formed in the outer intermediate surface and a plurality of second openings formed in a wall of the body surrounding the axially blind bore;
a plurality of second passages joining a plurality of third openings formed in the tapered wall and a plurality of fourth openings formed in the second surface; and
an entrance interconnecting the axially blind bore and the tapered wall.

2 . The apparatus of claim 1 , further comprising:
an axis extending through the body and interconnecting the first and second surfaces; in which the tapered wall is tapered at an angle of 60 degrees relative to the axis.

3 . The apparatus of claim 1 , further comprising an outer edge formed on the first surface; in which the tapered wall is situated between the outer edge and the entrance.

4 . A fluid end, comprising:
a fluid end body having a bore formed therein; and the apparatus of claim 1 installed within the bore.

5 . The apparatus of claim 1 , in which the plurality of first passages are formed offset from and do not intersect with any of the plurality of second passages.

6 . An apparatus, comprising:
a fluid routing plug configured to be installed within a fluid end, the fluid routing plug comprising:
a first end comprising a first tapered sealing surface and a plurality of first openings formed on the first tapered sealing surface;
an opposed second end comprising a second tapered sealing surface;
an intermediate surface joining the first and second ends;
a plurality of first fluid passages formed therein; and
a plurality of second fluid passages formed therein, the plurality of second fluid passages interconnecting the first and second ends;
in which each of the plurality of second fluid passages is joined to one of the plurality of first openings in a one-to-one relationship.

7 . The apparatus of claim 6 , in which the fluid routing plug further comprises a plurality of second openings formed on the second end.

8 . The apparatus of claim 6 , in which the second end of the fluid routing plug further comprises a base, the base comprising a plurality of second openings, each of the second openings joined to one of the plurality of second fluid passages in a one-to-one relationship.

9 . The apparatus of claim 8 , in which the second end further comprises an outer edge; in which the second tapered sealing surface extends between the outer edge and the base.

10 . The apparatus of claim 6 , in which the fluid routing plug further comprises an axis extending through the first and second ends; in which the second tapered sealing surface is formed at a non-zero angle relative to the axis.

11 . The apparatus of claim 10 , in which the non-zero angle is between 1 and 60 degrees.

12 . The apparatus of claim 6 , in which the first end further comprises an axially blind bore formed therein, the axially blind bore having an entrance.

13 . The apparatus of claim 12 , in which the first end further comprises an outer edge; in which the first tapered sealing surface is situated between the outer edge and the entrance.

14 . The apparatus of claim 6 , in which the intermediate surface comprises:
a first sealing surface configured to engage a first seal; and a second sealing surface configured to engage a second seal.

15 . The apparatus of claim 14 , in which the first and second seals are situated within a fluid end housing.

16 . A fluid end, comprising:
a fluid end housing comprising a rectilinear bore formed therein; the apparatus of claim 14 situated within the rectilinear bore; a first seal that is the first seal of claim 14 , the first seal installed within the rectilinear bore; and a second seal that is the second seal of claim 14 , the second seal installed within the rectilinear bore.

17 . The apparatus of claim 14 , in which the intermediate surface further comprises a beveled surface situated between the first sealing surface and the first end of the fluid routing plug.

18 . An apparatus, comprising:
a fluid routing plug configured to be installed within a fluid end, the fluid routing plug comprising:
a first surface, comprising:
a first tapered sealing surface having a plurality of first openings formed therein; and

an opposed second surface, comprising:
a second tapered sealing surface; and
a base having a plurality of second openings formed therein;

in which the first tapered sealing surface is configured to engage a first valve; and
in which the second tapered sealing surface is configured to engage a second valve.

19 . The apparatus of claim 18 , in which the first valve is a suction valve; and in which the second valve is a discharge valve.

20 . The apparatus of claim 18 , in which the fluid routing plug further comprises a plurality of passages formed therein, the plurality of passages joining the plurality of first openings and the plurality of second openings.
