Abstract
A valve assembly comprising a valve body, a valve housing, and a spring member coupling the valve body to the valve housing. The spring member is configured to align the contact surface of the valve body with the valve seat inside the valve housing. The spring member can be located on the discharge side of the valve body. The valve assembly may be disposed in a fluid end of a positive displacement pump that is operated to flow a wellbore servicing fluid into a wellbore.
Claims24
A valve assembly comprising:
- a valve body generally cylinder in shape with an outer surface and a valve seat contact surface;
- a valve housing generally cylinder in shape with an outer surface, an inner surface, and a valve seat;
- a spring member coupled to the valve body and the valve housing, and wherein the spring member is configured to bias the valve body into contact with the housing;
- and
- wherein the spring member is located on a discharge side of the valve body.
A pump fluid end comprising:
- a reciprocating element disposed at least partially within a reciprocating element bore of the pump fluid end;
- a discharge valve assembly;
- and
- a suction valve assembly,
- wherein the discharge valve assembly and/or the suction valve assembly is a valve assembly comprising a valve body, a valve housing, a spring member connecting the valve body to the valve housing, wherein the spring member is configured to bias the valve body into contact with a valve seat located on the valve housing, and wherein the spring member is located on a discharge side of the valve body.
A method of servicing a wellbore, the method comprising:
- fluidly coupling a pump to a source of a wellbore servicing fluid and to the wellbore;
- and communicating wellbore servicing fluid into the wellbore via the pump,
- wherein the pump comprises a pump fluid end and a pump power end, wherein the pump fluid end comprises:
- a reciprocating element disposed at least partially within a reciprocating element bore of the pump fluid end;
- a discharge valve assembly:
- and a suction valve assembly, wherein the discharge valve assembly or the suction valve assembly comprises a valve seat and a valve assembly, wherein the valve assembly comprises:
- a valve housing, a valve body, and a spring member coupling the valve body to the valve housing, wherein the spring member is located on a discharge side of the valve body;
- and wherein the pump power end is operable to reciprocate the reciprocating element within the reciprocating element bore of the pump fluid end.
