Abstract
A valve assembly of a fluid end of a pump may include a valve seat having a bore defining an inner surface and an outer surface of the valve seat, a first end configured to engage with a valve in a closed position of the valve, and a second end, opposite the first end, defining a groove surrounding the bore. The valve assembly may include a sacrificial ring, positioned in the groove, configured to control corrosion of a fluid end block of the fluid end.
Claims17
A valve assembly of a fluid end of a pump, comprising:
- a valve seat having a bore that provides a flow path through the valve seat and defining an inner surface and an outer surface of the valve seat, a first end configured to engage with a valve in a closed position of the valve, and a second end, opposite the first end, defining a groove surrounding the bore outside of the flow path of the valve seat, wherein the groove is from the outer surface of the valve seat extending inward toward the inner surface of the valve seat;
- and
- a sacrificial ring, positioned in the groove outside of the flow path of the valve seat, configured to control corrosion of a fluid end block of the fluid end, the valve seat having an outer diameter greater than an outer diameter of the sacrificial ring so that the valve seat is configured to contact the fluid end block without the sacrificial ring contacting the fluid end block.
A fluid end of a pump, comprising:
- a fluid end block defining a discharge bore;
- and
- a valve assembly installed in the discharge bore, the valve assembly comprising:
- a valve;
- a valve seat having a bore that provides a flow path through the valve seat and defining an inner surface and an outer surface of the valve seat, a first end configured to engage with the valve in a closed position of the valve, and a second end, opposite the first end, defining a groove surrounding the bore outside of the flow path of the valve seat, wherein the groove is from the outer surface of the valve seat extending inward toward the inner surface of the valve seat;
- and
- a sacrificial ring, positioned in the groove outside of the flow path of the valve seat, configured to control corrosion of the fluid end block, the valve seat having an outer diameter greater than an outer diameter of the sacrificial ring so that the valve seat contacts the fluid end block without the sacrificial ring contacting the fluid end block.
