A water outlet device for different water sprays from a same nozzle comprises a water outlet portion, and a control mechanism, the water outlet portion comprises a water outlet nozzle, the water outlet nozzle comprises a water outlet, the water outlet nozzle further comprises at least two water inlets, flow directions of the at least two water inlets are not parallel to a flow direction of the water outlet, the control mechanism is connected to the at least two water inlets to control a water inlet condition of each of the at least two water inlets, the water inlet condition comprises at least one of a flow volume or whether the water is flowing or not flowing, and the control mechanism controls the water inlet condition of each of the at least two water inlets to enable the water outlet nozzle to discharge the different water sprays.

A nozzle is provided having a low precipitation rate and uniform fluid distribution to a desired arcuate span of coverage. The nozzle has an inflow port having a shape corresponding to the desired arc of coverage and a size for effecting a low precipitation rate. The nozzle also has a deflector surface with a water distribution profile including ribs for subdividing the fluid into multiple sets of fluid streams. There are at least two fluid streams for distant and close-in irrigation to provide relatively uniform distribution and coverage. The nozzle may be a unitary, one-piece, molded nozzle body including a mounting portion, an inflow port, and a deflector portion.

A fire protection nozzle includes a body having two frame arms having proximal ends connected to an outlet of the body, and distal ends, the two frame arms defining a frame arm plane, and a junction formed by the distal ends of the frame arms, the junction including a central bore and an outer wall. A deflector is mounted to the body, and includes a planar member having a mounting hole in a center of the planar member to receive the outer wall of the junction, and a plurality of slots on a periphery of the planar member. The plurality of slots includes first slots, second slots, third slots, and fourth slots.

A sprinkler includes a connector, a body, at least one pin, and a deflector. The connector extends between an inlet end and an outlet end. The body includes a pin wall extending from the outlet end of the connector. The pin wall defines at least one pin receiver. The body wall extends from the pin wall. The pin wall and the body wall define a chamber. The at least one pin is fixed with the at least one pin receiver. The deflector is coupled with the at least one pin to move within the chamber along the at least one pin responsive to a trigger condition from an undeployed state to a deployed state.

The valve core assembly includes a valve housing member, an actuating member, a control plate, a moving plate member, a static plate member, a valve seat member and a sealing member coupled to obtain the valve core assembly. The valve housing member includes a first end portion and a second end portion. The actuating member is rotatably disposed in the valve housing member along the first end portion. The control plate is disposed in the second cavity and coupled to the actuating member. The moving plate member is coupled to the control plate and disposed in the second cavity. The static plate member is disposed adjacent to the moving plate member in the second cavity. The valve seat member is detachably coupled to the valve housing member. The sealing member is removably disposed in a cutout portion of the valve seat member. The valve seat member includes design variations.

A nozzle for an atomizer includes a plate, a piezoelectric actuator, a body, and a connector. The plate defines an aperture. The actuator is configured to oscillate the plate. The body supports the plate. The connector is configured to reversibly mount the body to the atomizer in a first orientation and in a second orientation. In the first orientation, fluid exits the nozzle along a first axial direction through the aperture. In the second orientation, fluid exits the nozzle along an opposite axial direction through the aperture.

A dry fire protection sprinkler assembly. The sprinkler assembly includes an elongate tubular outer housing having a first end and a second end opposite the first end. The second end of the housing defines a fluid discharge end of the sprinkler assembly having an outlet opening. A fluid deflection member is affixed to the housing at a preferably fixed distance from the outlet opening. The sprinkler assembly and the fluid deflection member define an unencumbered fluid flow path for a column of fluid discharge from the outlet opening. The fluid deflection member includes at least one tab to act on the unencumbered column of fluid discharge.

A flow suppression device adapted to be connected to a high pressure fluid system includes an outer flow containment member of a porous and flexible construction. The outer flow containment member has an upstream end and a downstream end opposite the upstream end. The upstream end includes an inlet opening adapted to receive a flow stream of pressurized fluid from the high pressure fluid system and the downstream end being substantially closed. The flow suppression device also includes a primary inner flow containment member of a porous and flexible construction contained within the outer flow containment member. The primary inner flow containment member has an upstream end with an inlet opening adjacent the inlet opening of the outer flow containment member and a downstream end opposite the upstream end of the primary inner flow containment member.
