Abstract
A valve seat for use within a hydraulic fracturing pump includes a first portion including a strike face for interacting with a reciprocating component associated with the valve seat. The valve seat also includes a second portion having a recess to receive at least a portion of the first portion, the first portion being coupled to the second portion using a hybrid joining method that includes both a mechanical fastener to secure the first portion to the second portion and a joining process to secure the first portion to the second portion.
Claims32
A valve seat for use within a hydraulic fracturing pump, the valve seat comprising:
- a first portion including:
- a strike face for interacting with a reciprocating component associated with the valve seat;
- and
- a first bore extending axially through the first portion;
- a second portion including:
- a recess in which at least a portion of the first portion is received;
- a second bore extending axially through the second portion and substantially aligned with the first bore;
- and
- an aperture extending from a circumference of the second portion to the recess;
- and
- a mechanical fastener extending through the aperture and at least partially into the first portion thereby to prevent any axial movement of the first portion relative to the second portion in a first axial direction and a second axial direction opposite the first axial direction,
- the first portion being coupled to the second portion via the mechanical fastener and via one or more of a press fit, a thermal shrink fit, brazing, welding, fusing, or cementing via adhesive.
A valve assembly, comprising:
- a valve member configured to reciprocate within a bore;
- and
- a valve seat having a strike face, the strike face positioned to contact the valve member, the valve seat comprising:
- a first portion including:
- at least a portion of the strike face;
- and
- a first bore extending axially through the first portion;
- a second portion including:
- a recess in which at least a portion of the first portion is received;
- a second bore extending axially through the second portion and substantially aligned with the first bore;
- and
- an aperture extending from a circumference of the second portion to the recess;
- and
- a mechanical fastener extending through the aperture and at least partially into the first portion thereby to prevent any axial movement of the first portion relative to the second portion in a first axial direction and a second axial direction opposite the first axial direction,
- the first portion being coupled to the second portion via the mechanical fastener and via one or more of a press fit, a thermal shrink fit, brazing, welding, fusing, or cementing via adhesive.
