Abstract
A valve member for a valve assembly includes a body. The valve member also includes a first sealing assembly, coupled to the body at a first end, the first sealing assembly forming at least a portion of a first end strike face. The valve member further includes a second sealing assembly, coupled to the body at a second end opposite the first end, the second sealing assembly forming at least a portion of a second end strike face. The valve member also includes a guide leg assembly coupled to the body at the first end.
Claims20
A valve assembly for a fracturing pump, comprising:
- a valve seat having a bore, the valve seat having a strike face;
- and
- a valve member positioned to reciprocate within the bore, the valve member moving between open and closed positions, the valve member comprising:
- a body without a through hole;
- a first sealing assembly positioned proximate a first body strike face at a first side of the body;
- a second sealing assembly positioned proximate a second body strike face at a second side of the body, the second side being opposite the first side;
- and
- legs removably coupled to the body, the legs being coupled to the first side of the body via a coupling assembly at an interface between the coupling assembly and an end of the body at a central portion of the body, the coupling assembly restricted to a first side of the body opposite a second side, and the interface being a first distance from an end of the second body strike face that is smaller than a second distance between the end of the second body strike face and the first body strike face.
A valve member for a valve assembly, comprising:
- a body without a through hole;
- a first sealing assembly, coupled to a first side of the body, the first sealing assembly forming at least a portion of a first strike face;
- a second sealing assembly, coupled to a second side of the body, opposite the first side, the second sealing assembly forming at least a portion of a second strike face;
- a guide leg assembly coupled to the first side of the body;
- and
- a mounting platform positioned on the first side of the body, the mounting platform extending axially away from a body base, the mounting platform extending a platform distance such that an end of the mounting platform is axially closer to the body base than a bottom of the first strike face, and the guide leg assembly having an opening that receives at least the end of the mounting platform and the guide leg assembly contacting the base when the end of the mounting platform is within the opening.
A method for adjusting a valve member, comprising:
- removing a valve member from a pumping assembly, the valve member being in a first orientation that positions a first sealing assembly in a downward facing position and comprising a valve member body without a through hole;
- detaching legs from a first side of the valve member body;
- changing an orientation of the valve member body to a second orientation, different from the first orientation, the second orientation positioning a second sealing assembly, separate from the first sealing assembly, in the downward facing position;
- attaching legs to a second side of the valve member body, the legs engaging a coupling interface recessed from a second strike face on the second side of the valve member body, the coupling interface being a first distance from the first strike face that is smaller than a second distance between the first strike face and a bottom of the second strike face;
- and
- installing the valve member into the pumping assembly in the second orientation.
