Abstract
Embodiments of a manifold of a hydraulic fracturing system include a junction having an inlet flow bore. The junction can include an integrated flow junction and valve check assembly having a body including a central portion and one or more side portions. The central portion can be positioned between a pair of manifold sections of the manifold and attached thereto. The one or more side portions extend radially from the central portion and include an inlet bore through which a pressurized fluid is received and supplied to the manifold. One or more check valves is positioned along the inlet bore so as to be integrated within the body of the junction.
Claims18
A manifold of a hydraulic fracturing system comprising:
- a plurality of manifold sections;
- and
- one or more junctions positioned between adjacent manifold sections, the one or more junctions including:
- a body comprising:
- an upstream end configured to connect with a first manifold section,
- a downstream end spaced from the upstream end and configured to connect to a second manifold section, and
- a throughbore extending longitudinally between the upstream end and the downstream end, so that when the junction is installed between the first and second manifold sections, the throughbore is axially aligned with a fluid flow passage of the manifold,
- one or more inlet bores extending axially through the body from a first end having an inlet opening located along a distal end of a side portion of the body to a second end having an outlet opening in communication with the throughbore, so that when a pressurized fluid is received through the inlet opening and is directed along the one or more inlet bores to the outlet opening for introducing the pressurized fluid into the fluid flow passage of the manifold, and
- one or more check valves internally mounted within the side portion of the body along the one or more inlet bores so as to be integrated within the body of the junction and configured to restrict a flow of the pressurized fluid along the one or more inlet bores.
A junction for a manifold of a hydraulic fracturing system, the system comprising:
- a body including:
- (a) a central portion having a longitudinally extending throughbore positioned in communication with a fluid flow passage extending through the manifold and along which a fluid is transported;
- (b) one or more side portions extending radially from the central portion, the one or more side portions including one or more inlet bores extending therethrough, the one or more inlet bores configured to define a flow path extending between an inlet in communication with the throughbore and an outlet at a terminal end of the one or more side portions and along which at least a portion of the fluid is directed away from the manifold;
- and
- one or more check valves positioned along the one or more inlet bores and integrated within the body, the one or more check valves configured to substantially restrict a backflow of the fluid passing through the one or more inlet bores.
A hydraulic fracturing system comprising:
- a manifold assembly including one or more manifolds having a fluid flow passage defined therethrough and along which a pressurized fracturing fluid is transported;
- a series of junctions located along the one or more manifolds, each junction including:
- a body including a throughbore aligned with and in fluid communication with the fluid flow passage of the one or more manifolds;
- one or more inlet bores extending radially with respect to a longitudinal axis of the one or more manifolds through the body and away from the throughbore, the one or more inlet bores defining an inlet flow path extending from an inlet opening located along an outer surface of the body through the body and to an outlet opening located at the throughbore, so that when a flow of the pressurized fracturing fluid is received through the inlet opening and is directed toward the outlet opening for introduction of the pressurized fracturing fluid into the one or more manifolds;
- and
- one or more valves positioned along the one or more inlet bores, integrated within the body, and operable to regulate the flow of the pressurized fracturing fluid passing along the one or more inlet bores.
