Water mist nozzles refer to nozzles that, under the action of a certain water pressure, decompose the water flow into water droplets smaller than 1 mm and spray them according to the designed sprinkler shape. The ZSTWA water mist nozzle is a common type of water mist nozzle. It is a type A water mist nozzle. Its water inlet and outlet are at a certain angle, a centrifugal atomization nozzle.

ZSTWA water mist nozzle atomization angle:

The atomization angle refers to the water mist ejected from the water mist nozzle forming a cone that expands around the axis of the nozzle, and the cone apex angle is the atomization angle of the water mist nozzle.

The common atomization angles of ZSTWA water mist nozzles are 45°, 60°, 90°, 120°, and 150° (for water mist nozzles of foam spray fire extinguishing systems, the atomization angle should not be greater than 90°). In addition, water mist nozzles with other atomization angles are allowed to be used.

Working principle of ZSTWA water mist nozzle:

When the water flow enters the nozzle, it is decomposed into a rotating water flow with centrifugal speed moving along the inner wall and a straight water flow with axial speed. The two water flows merge in the nozzle, and then are ejected from the nozzle at their combined speed to form atomization.
