摘要： A valve assembly includes a valve body defining an internal region, an inlet passageway, and an outlet passageway, wherein the inlet and outlet passageways fluidly communicate with the internal region. A valve seat is positioned within the internal region defining a fluid passageway. A hanger is connected to the valve body. A linkage assembly is pivotally and rotatably to the hanger and a valve member is pivotally connected to the hanger via the linkage assembly, wherein the valve member is movable between an open configuration, in which fluid flow is permitted through the fluid passageway, and a closed configuration, in which the valve member engages the valve seat to at least partially restrict fluid flow through the fluid passageway.

摘要： A fluid end block for a reciprocating pump defines a fluid chamber and a packing bore. An outlet fluid passage is formed in the fluid end block in communication with the fluid chamber and includes an outlet valve. An inlet fluid passage is formed in the fluid end block in fluid communication with the fluid chamber and includes an inlet valve. A plunger is reciprocally disposed in the packing bore. Packing in the packing bore is positioned to contact the plunger and a packing sleeve is disposed between the packing and the packing bore. The packing sleeve is a hollow cylinder with inner and outer surfaces and an inner end configured to be inserted into the packing bore. The inner end includes a bevel extending between the outer surface and the inner end, the outer surface including a notch formed therein adjacent the inner end.
