Abstract
A valve assembly for a fracturing pump includes a valve seat having a bore, the valve seat having an upper region forming at least a portion of a strike face. The valve assembly also includes a groove and a valve seat insert positioned within the bore. The valve seat insert includes a body portion extending at least a portion of a bore length. The valve seat insert also includes an insert bore extending through the body portion. The valve seat insert further includes an upper insert region, at least a portion of the upper insert region positioned within the groove. The valve assembly also includes a valve member positioned to reciprocate within the bore, the valve member moving between an open position and a closed position.
Claims13
A valve assembly for a fracturing pump, comprising:
- a valve seat having a bore, the valve seat having an upper region forming at least a portion of a strike face;
- a fluid end block having a passage supporting the valve seat;
- a groove formed in the upper region of the valve seat;
- a valve seat insert positioned within the bore of the valve seat, the valve seat insert comprising:
- a body portion extending at least a portion of a bore length;
- an insert bore extending through the body portion;
- an upper insert region, at least a portion of the upper insert region positioned within the groove, the upper insert region forming at least a portion of the strike face;
- and
- a channel formed in the body portion, the channel extending radially into the body portion toward the bore of the valve seat and having a channel diameter larger than an insert bore diameter;
- and
- a valve member positioned to reciprocate within the bore of the valve seat, the valve member moving between an open position and a closed position, wherein at least a portion of the valve member engages at least a portion of the strike face in the closed position.
A valve seat for use in a fracturing pump, comprising:
- a first body, including a groove formed in the first body and a tapered portion extending from the groove and along a first longitudinal bore extending through the first body, a radial thickness of the tapered portion increasing along the first longitudinal bore;
- a second body positioned at least partially within the groove, the second body including a slanted face that substantially conforms to the tapered portion;
- and
- a third body, arranged within the first longitudinal bore, the third body extending along at least a portion of a first bore length, the third body having a second longitudinal bore coaxial with the first longitudinal bore, and a second bore diameter that is less than a first bore diameter.
