摘要： A fracturing system includes a first trailer-mounted fracturing manifold including a plurality of first fluidly-connected junctions and a second trailer-mounted fracturing manifold including a plurality of second fluidly-connected junctions. A flexible conduit fluidly connects an initial junction of the first junctions to a terminal junction of the second junctions to place the first trailer-mounted fracturing manifold in series connection with the second trailer-mounted fracturing manifold.

摘要： A retainer nut assembly for a fluid end of a pump system includes a fastener with a generally cylindrical configuration, first and second ends, external threads configured to engage corresponding threads of a fluid end block, and a cavity formed at the first end. A suction cap is configured to sealingly fit to the fluid end block. A load piston is movably disposed in the cavity adjacent the suction cap. A bore is formed through the fastener in communication with the cavity and provided with hydraulic fluid. A pressure piston is movably disposed in the bore. A threaded passageway is formed through the fastener in communication with the bore and open to the second end. A locking bolt is disposed in the threaded passageway and, when inserted into the threaded passageway, contacts the pressure piston and generates fluid pressure on the load piston.

摘要： A valve assembly includes a valve body that defines an internal flow passageway between an inlet and an outlet, and a valve seat disposed in the valve body with a sealing surface perpendicular to the flow passageway. The valve assembly further includes a clapper pivotally correlated to the valve seat having a closed configuration extending across the valve seat configured to substantially close off the flow passageway, and an open configuration configured to substantially allow fluid flow in the flow passageway from the inlet to the outlet through the valve body. An annular valve seat seal is disposed within an annular groove formed in a surface of the valve seat, where the annular valve seat seal is disposed at an interface between the valve seat and the clapper when the clapper is in the closed configuration.

摘要： A valve member for an inlet or outlet valve assembly of a reciprocating pump assembly includes a valve body and a seal member. The valve body comprises a first body surface and a second body surface that extend circumferentially about the valve body. The valve body defines a body axis and an annular cavity. The seal member is positioned at least partially within the annular cavity of the valve body such that an outer seal portion of the seal member extends between the first body surface and the second body surface of the valve body. The outer seal portion of the seal member comprises a first seal surface and a second seal surface. The first body surface, the first seal surface, and the second seal surface extend at different angles relative to the body axis.

摘要： A valve assembly adapted for use in oil and gas operations. In one aspect, the valve assembly includes a valve body defining an internal region, an inlet passageway, and an outlet passageway, the inlet and outlet passageways extending into the internal region; a valve seat connected to the valve body and defining a fluid passageway; a clapper extending within the internal region and defining an annular groove; and a seal extending within the annular groove of the clapper and adapted to sealingly engage the valve seat. In an example embodiment, the clapper is actuable between an open configuration, in which fluid flow is permitted through the fluid passageway; and a closed configuration, in which the seal sealingly engages the valve seat to at least partially restrict fluid flow through the fluid passageway.

摘要： A seal packing assembly for a hydraulic pump includes a plurality of annular dynamic seals disposed within annular grooves circumferentially defined in the annular bore, a packing gland circumferentially housing a section of the plunger, and a plurality of seal manifolds distributed and defined within the packing gland, each seal manifold defining a port at one end exposed to the pumping fluid and further defining a clean lubrication fluid inlet proximate to a second end, the fluid inlet coupled to a lube pump via a check valve, where the clean lubrication fluid housed in the seal manifolds is maintained at a constant pressure. Each seal manifold includes a piston disposed within the seal manifold having a first end configured with a first surface area to interface with the pumping fluid and a second end configured with a second surface area to interface with the clean lubrication fluid, and a fluid port configured to provide fluid communication between the seal manifold and the annular grooves of the annular dynamic seals.

摘要： A dart valve comprises a valve housing. The valve housing comprises a valve inlet, a valve outlet, a housing wall and an aperture extending through the housing wall between the valve inlet and valve outlet. The dart valve further comprises a valve cartridge. The valve cartridge comprises a cartridge housing configured to allow fluid to flow therethrough from a cartridge inlet to a cartridge outlet; and a valve plunger slidably mounted in the cartridge housing and configured to selectively allow fluid to flow from the cartridge inlet to the cartridge outlet. The valve cartridge is configured to be inserted through the aperture for removably mounting the valve cartridge within the valve housing, in a mounted position, such that the valve inlet is in communication with the cartridge inlet, the cartridge outlet is in communication with the valve outlet and fluid is able to flow from the valve inlet to the valve outlet through the valve cartridge.

摘要： A fluid pump may include a fluid chamber, a plunger configured to reciprocate within the fluid chamber, and a valve system including multiple valves. The multiple valves each may be configured to control fluid flow into the fluid chamber or each may be configured to control fluid flow out from the fluid chamber.
