Abstract
A floor nozzle assembly and systems and methods for distributing firefighting suppressant. The floor nozzle assembly has a body and deflector in contact with one another to form a plurality of passageways through which flows the firefighting suppressant. The deflector has a deflector flange and a plurality of projecting members in contact with the body to form the passageways. The nozzle assembly has a radial outer portion at each projecting member having a plurality of curved edges with at least two different curvatures and each passageway is formed by parallel planar sidewalls.
Claims20
A floor nozzle comprising:
- a body having a mounting portion configured to couple to a fire suppressant supply pipe and a body flange portion axially spaced from the mounting portion with an internal transverse passage extending therebetween along a central nozzle axis, the transverse passage defining an inlet opening and an outlet opening with the body flange portion extending around the outlet opening, the body flange portion including an upper support surface;
- and
- a deflector supported on the upper support surface of the body flange portion, the deflector having a deflector flange including an upper surface disposed normal to the central nozzle axis, a lower surface angled with respect to the upper surface and an outer perimeter between the upper surface and the lower surface circumscribing the nozzle axis to define a linear frustoconical portion of the deflector that extends radially inward at a radial length from the outer perimeter, the deflector flange including a plurality of projecting members each having a radial inner portion and a radial outer portion, the plurality of projecting members extending from the lower surface of the deflector flange in supporting contact with the upper support surface of the body flange portion, the upper support surface of the body flange portion being angled with respect to the upper surface of the deflector flange, the plurality of projecting members being circumferentially spaced around the outlet opening to form a plurality of passageways therebetween each having a converging inlet portion and a diverging outlet portion,
- wherein the radial outer portion of each of the projecting members having a first curved edge, a second curved edge, and a third curved edge between the first and second curved edges having a different curvature than the first curved edge and the second curved edge, the first and second curved edges having a same curvature.

A floor nozzle assembly, comprising:
- a nozzle including:
- a body, and
- a deflector supported on the body, the deflector including an upper surface and a plurality of projection members between the body and the deflector circumferentially spaced about a central axis, each projection member having a radial outer portion including a first curved edge, a second curved edge, and a third curved edge between the first and second curved edges having a different curvature than the first curved edge and the second curved edge, the first and second curved edges having a same curvature;
- and
- a mounting assembly including a floor grate having a recessed cavity with a transverse opening for receiving and supporting the floor nozzle such that the upper surface of the deflector is flush with the floor grate.
2 more elements
A floor nozzle, comprising:
- a body;
- a deflector supported on the body;
- and
- a plurality of projection members between the body and the deflector circumferentially spaced about a central axis of the deflector, each projection member having a radial outer portion having a first curved edge, a second curved edge, and a third curved edge between the first and second curved edges having a different curvature than the first curved edge and the second curved edge, the first and second curved edges having a same curvature;
- wherein an outer perimeter of the deflector defines a radius to the central axis of the deflector, and
- wherein the third curved edge of the radial outer portion of each of the projecting members having a radius corresponding to the radius of an outer perimeter of the deflector.
3 more elements
A deflector for a floor nozzle, the floor nozzle including a body, the deflector comprising:
- a plurality of projection members circumferentially spaced about a central axis of the deflector, each projection member having a radial outer portion including a first curved edge, a second curved edge, and a third curved edge between the first and second curved edges having a different curvature than the first curved edge and the second curved edge, the first and second curved edges having a same curvature, and
- wherein an outer perimeter of the deflector defines a radius to the central axis of the deflector, and
- wherein the third curved edge of the radial outer portion of each of the projecting members having a radius corresponding to the radius of an outer perimeter of the deflector.
