摘要： An integrated valve and manifold assembly includes a water valve configured to control water flow from one or two valve outlets. At least one of the outlets is coupled to a manifold. In some examples, the manifold is a dual-extrusion manifold having at least one air channel and at least one water conduit, and the water valve has a pair of air channels attached to a periphery of the water valve and configured to couple to the manifold air channels. In examples wherein at least one of the manifolds is a dual-extrusion manifold, a top portion of the assembly includes an air valve configured to control flow of air to air channel(s) of the dual-extrusion manifold. In other examples, the assembly includes a one-outlet or two-outlet water valve configured to couple to water manifolds, with no attached air channels or air valves.

摘要： A device for controlling a flow and distributing a fluid, in particular a refrigerant, in a fluid circuit. The device exhibits a housing with connections for connection to fluid lines that are connected to one internal volume of the housing via a pass-through opening, and one valve element that is arranged in the internal volume of the housing and exhibits a drive element for moving the valve element relative to the housing. The valve element exhibits one pass-through opening and is mounted in such a way that it can be moved linearly in the axial direction along a longitudinal axis such that a passage for the fluid is opened between a first connection produced as an inlet and a second connection produced as a primary outlet or a third connection produced as a secondary outlet.

摘要： A multi-port valve provides three inlets and three outlets. In many embodiments, seven flow configurations are provided. A stemshell can rotate internal to a housing to direct fluid from specific inlets to specific outlets while saving flow through various inlet/outlet ports as required by the various flow configurations.

摘要： The present disclosure discloses a socket device comprising a fixing portion. The fixing portion comprises a socket portion, a water inflow passage, a first water outflow passage, a second water outflow passage, a first switching mechanism, a first water dividing passage, and a first control mechanism. The socket portion comprises a switch. The second water outflow passage, the first water outflow passage and the second water outflow passage are switched to be connected to the water inflow passage by the first switching mechanism. The switch is connected to the first switching mechanism to drive the first switching mechanism. The first control mechanism is configured to control the water inflow passage to be connected to the first water dividing passage or control the first water dividing passage to be opened or to be closed.

摘要： Passage forming blocks of a first pilot valve and a second pilot valve each include a supply passage, which opens in a first surface and a second surface and is connected to a valve chamber, a first output passage, which opens in the first surface and are connected to the valve chamber, and a second output passage, which opens in the first surface. Further, the passage forming blocks each include an output passage connecting recess. The output passage connecting recess is provided in a section of the second surface that overlaps with an opening region of the first output passage, which opens in the first surface, and is connected to the second output passage. The first output passage of the first pilot valve is connected to the second output passage of the second pilot valve via the output passage connecting recess of the second pilot valve.

摘要： A liquid dispensing apparatus has a main pipe, a plurality of secondary pipes and a plurality of tertiary pipes that allow a user to fill multiple containers simultaneously. The inlet of the main pipe receives a liquid from a liquid source and travels through main pipe, secondary pipes, tertiary pipes and exits outlet into many containers. The diameter of the tertiary pipes is narrower than the diameter of the main pipe which causes an increase in velocity as the liquid travels through device. The apparatus may also contain an option piercing tip with a piercing needle, allowing the user to fill multiple squeeze containers with their lids on.

摘要： A valve operating member includes a valve support portion, which supports a valve disk while allowing the valve disk to move relative to the valve operating member in a direction of an axis. An elastic member is disposed inside a valve chest. The elastic member constantly urges the valve disk toward the valve seat in the direction of the axis to cause the valve disk to be seated on the valve seat with an urging force. The valve support portion includes a valve engagement portion, which is engaged with an engaged portion of the valve disk seated on the valve seat, and separates the valve disk apart from the valve seat. When the valve disk is seated on the valve seat, the valve engagement portion is not in contact with the valve disk in the direction of the axis.

摘要： A circulation sub including a tubular and a diverter valve are configured to continuously circulate fluid into a drill string. The tubular has a first end connectable to the drill string, a second end connectable to a pipe segment, and a port. The tubular has a fluid path for allowing the fluid to flow from the pipe segment to the drill string and a circulation path for allowing the fluid to flow from the port to the drill string. The diverter valve has a channel in selective fluid communication with the fluid path. The diverter valve is positionable between a flow through position for selectively allowing the fluid to flow through the fluid path and a diversion position for selectively allowing the fluid to flow through the circulation path whereby the fluid may continuously flow through the drill string.

摘要： A multi-well pad for fracturing a subterranean formation can include a valve assembly that includes a shuttle valve, an inlet, a first outlet, and a second outlet, where the inlet is coupled to a fracturing pump, where the first outlet is coupled to a first well, where the second outlet is coupled to a second well, where first shuttle valve has a first position and a second position. The fracturing pump and the first well can form a continuous first path through the valve assembly while closing off a second path between the fracturing pump and the second well when the shuttle valve is in the first position. The fracturing pump and the second well can form a continuous second path through the valve assembly while closing off the first path between the fracturing pump and the first well when the shuttle valve is in the second position.
