Problems solved by technology

However, there are difficulties in economically producing hydrocarbons from low permeability rock formations.
Often, large quantities of proppants are suspended in the hydraulic fracturing fluid and flow into the fractures during the pumping stage.
These effects can be detrimental to the entire pumping system.
These stresses can reduce the life of the fluid end and its internal components.
A number of issues can arise with conventional valve seats.
Additionally, when leakage occurs around the valve seat, it can be difficult to detect.
Moreover, the valve seat and valve head can undergo extensive wear on sealing surfaces when the valve head continuously contacts the valve seat in the same location and same orientation.
When this effect occurs over numerous open / close cycles or throughout the life span of the valve assembly, pre-mature wear of one or more components can result.

Embodiment Construction

[0015]Generally described herein is a valve seat for the fluid end of a hydraulic fracturing pump, wherein the valve seat is generally formed of a substantially cylindrical body defined along an axis and having a first seat end and a second seat end with a through bore extending between the first and second seat ends. The valve seat body has an inner cylinder surface and an exterior cylinder surface with an annular flange formed along the exterior cylinder surface adjacent the first seat end, which flange defines a flange shoulder. The bore expands from a first diameter to a second diameter adjacent the first seat end. In one or more embodiments, the valve seat further includes an annular groove formed in the exterior cylinder surface between the flange shoulder and the second seat end. In one or more embodiments, the valve seat includes a helical groove formed in the inner cylinder surface along a portion of the length of the cylinder between the first seat end and the second seat ...

Abstract

The present disclosure provides a valve seat assembly for a fluid end of a hydraulic fracturing pump. The valve seat assembly includes a valve seat having a substantially cylindrical body defined along an axis. The valve seat has a first seat end and a second seat end with a through bore extending between the first and second seat ends. The cylindrical body has an inner cylinder surface and an exterior cylinder surface with an annular flange formed along the exterior cylinder surface adjacent the first seat end. The through bore expands from a first diameter to a second diameter adjacent the first seat end. The valve seat assembly further includes a leak detection notch formed in the exterior cylinder surface between the annular flange and the second seat end.

Description

PRIORITY CLAIM[0001]The present application claims priority to U.S. Non-Provisional Application Ser. No. 16 / 580,332, entitled “Rotating Seat Assembly,” filed Sep. 24, 2019, which claims the benefit of U.S. Provisional Application No. 62 / 735,574, entitled “Rotating Seat Assembly,” filed Sep. 24, 2018, herein incorporated by reference in its entirety.TECHNICAL FIELD OF THE INVENTION[0002]The present application relates generally to a reciprocating pump, and in particular to a valve seat for use in a suction or discharge valve assembly.BACKGROUND OF THE INVENTION[0003]In the modern-day oil and gas industry, unconventional reservoir plays continue to maintain outsized importance. However, there are difficulties in economically producing hydrocarbons from low permeability rock formations. One way to boost production rates is using hydraulic fracturing, a technique that increases rock permeability by opening channels through which hydrocarbons can flow to recovery wells. During hydraulic ...
