Abstract
A valve seat at least partially formed of a ceramic material for use in a fracturing pump includes a first body and a second body. The first body is configured to be inserted into a fluid passageway of the fracturing pump. The first body has an outer diameter, D1. The second body extends radially from the first body and has an outer diameter, D2, greater than the outer diameter, D1, of the first body. The second body is at least partially formed of the ceramic material.
Claims14
A valve assembly for use in a fracturing pump, the valve assembly comprising:
- a valve member reciprocatably movable into and out of engagement with a valve seat body to configure the valve assembly between open and closed positions;
- wherein the valve seat body includes a first end and a second end, the valve seat body configured to be inserted into a fluid passageway of the fracturing pump, the valve seat body having an inner cylindrical surface, wherein the first end has an outer diameter, D1;
- the second end having a seating surface facing the valve member, the second end having an outer diameter, D2, greater than the outer diameter, D1, such that the difference between the diameters D2 and D1 allows the valve seat body to be supported by the fluid passageway;
- a recessed portion disposed on at least one of the second end seating surface of the valve seat body or the valve member;
- and
- an insert formed of a ceramic material and disposed within the recessed portion for forming a seal when the valve assembly is in the closed position.

A reciprocating pump assembly, comprising:
- a power end coupled to a fluid end, the fluid end having a fluid inlet passage co-axially aligned with a fluid outlet passage;
- a valve assembly disposed within each of the fluid inlet passage and the fluid outlet passage, each valve assembly comprising:
- a valve member reciprocatably movable into and out of engagement with a valve seat body to configure the valve assembly between open and closed positions;
- wherein the valve seat body includes a first end and a second end, the valve seat body having an inner cylindrical surface and an outer surface, wherein the outer surface at the first end has an outer diameter, D1, the second end having a seating surface facing the valve member, the second end having an outer diameter, D2, greater than the outer diameter, D1, such that the difference between the diameters D2 and D1 allows the valve seat to be supported by sidewalls forming the respective fluid inlet and outlet passages;
- an insert formed of ceramic, and
- a recessed portion formed on the seating surface, the recessed portion formed having a bottom wall and a pair of sidewalls sized to receive an insert formed of a ceramic material for contacting the valve member when the valve assembly is in the closed position.
