Spray head for uniform fluid distribution and fluid distribution system

摘要

A spray head comprising - a body (1) defining a central axis and further comprising a fixing structure (3) for attaching the spray head to a fluid supply system (12), - a fluid inlet , which directs fluid in a first direction, - a plurality of outlet orifices (6, 7, 19, 20, 26, 27) arranged around the central axis, and - a flow path between the inlet and the orifices (6, 7, 19, 20, 26, 27), and wherein the body further comprises an arrangement (5) for supporting a fire-control actuating element (13), in which a first set of holes (6, 19, 26 ) is located in such a way that the fluid leaves the first set of holes in a second direction opposite the first direction in which the angle formed between the first direction (35) of the fluid and the second direction (33, 34) is in the interval between 125-175 degrees, in which the first set of holes (6, 19, 2 6) is located at a smaller radial distance from the central axis than a second set of holes (7, 20, 27), in which the first set of holes (6, 19, 26) is located closer to the entrance of fluid that the second set of holes (7, 20, 27), and in which the fluid leaves the second set of holes (7, 20, 27) in a third direction and in which the angle formed between the first direction and the third direction is in the range between 89-139 degrees.
