Patent number: 10941765Abstract: A flangeless fluid end comprising a fluid end body releasably attached to a connect plate. The connect plate is attached to a power source using stay rods. The flow bores of the fluid end are sealed without threading a retainer nut into the walls of each bore. Instead, the flow bores are sealed by bolting a retainer to the fluid end body. Plungers to drive fluid through the fluid end body are installed within removable stuffing box sleeves. These sleeves are maintained within the plunger bores by the bolted retainers. A number of features, including the location of seals within bore walls and carbide inserts within valve structures, aid in reducing or transferring wear.Type: GrantFiled: December 10, 2019Date of Patent: March 9, 2021Assignee: Kerr Machine Co.Inventors: Mark S. Nowell, Kelcy J. Foster, Christopher Todd Barnett, Brandon Scott Ayres, Michael Eugene May, Guy J. Lapointe, Micheal Cole Thomas

Publication number: 20190368619Abstract: A valve for use in a fluid end. The valve has a solid body with a sealing surface. The valve may move into position where the valve contacts a valve seat. When in contact, the valve and valve seat prevent flow through the valve. The valve and valve seat each have hardened inserts in their respective strike faces. The insert in the valve is less hard than the insert in the valve seat. Both are typically made of a ceramic material, such as tungsten carbide.Type: ApplicationFiled: July 16, 2019Publication date: December 5, 2019Inventors: Christopher Todd Barnett, Mark S.

Publication number: 20190309858Abstract: A stem-guided valve for use inside of a fluid end. The valve body is installed in a conduit that traverses the fluid end housing. A removable guide element is installed within a bore formed in the valve body. A static component that is interposed within the conduit includes an elongate projecting stem. As the stem reciprocates axially with the guide element, the valve is caused to move between open and closed positions. In its closed position, the valve body engages a valve seat that surrounds the conduit. A plurality of perforations are formed in the walls of the guide element, the perforations allow fluid to drain from the guide element during operation.Type: ApplicationFiled: April 4, 2019Publication date: October 10, 2019Inventors: Mark S.

Publication number: 20180266573Abstract: A plug valve having an improved sealing assembly. The valve has a body, and a bore formed in the body. The bore is configured to receive a plug and an insert. Recesses are formed in the valve in the internally disposed surface of the bore for placement of seals, which interact with an externally disposed sealing surface of the insert. The plug and insert have complementary surfaces that prevent fluid from passing through the annulus between the plug and insert.Type: ApplicationFiled: April 17, 2018Publication date: September 20, 2018Inventors: Mark S.

Publication number: 20180238459Abstract: A check valve with a flapper for directing high pressure abrasive fluid away from its sealing face. The check valve has a flapper which opens when fluid travels from an inlet to an outlet. The flapper closes when fluid flow stops or reverses by sealing a flat sealing face to a seal formed in a shoulder face of the valve. A surface feature protrudes from near the flat sealing face and forms a slanted face opposed to the direction of flow through the valve. This slanted face interfaces with fluid flow to more easily open the valve and directs flow away from the sealing face to reduce wear.Type: ApplicationFiled: February 21, 2018Publication date: August 23, 2018Inventors: Mark S.

Publication number: 20170299096Abstract: A high pressure swivel joint used in pipe assemblies transferring high pressure fluid. The swivel joint comprises a first pipe section and a sleeve-like second pipe section. The first pipe section is inserted into the second pipe section and the sections are relatively rotatable. A radial seal is seated in a groove formed in either the outer circumference of the first pipe section, or the inner circumference of the second pipe section. The groove is axially spaced from the location where the two pipe sections abut. Alternatively, a groove may be formed in both the outer circumference of the first pipe section and the inner circumference of the second pipe sections, the grooves both being axially spaced from the location where the two pipe sections abut. A radial seal may be inserted in both grooves and a wear ring positioned between the seals.Type: ApplicationFiled: April 17, 2017Publication date: October 19, 2017Inventors: Mark S.
