Spiral nozzle

Spiral nozzle
Spiral nozzle at work in the liquid into the spiral into a spiral metal protruding from the outer nozzle. This breaks the traditional fluid into the relatively fine number of concentric rings that will form the complete spray pattern of the conical spray shape. The resulting non-uniform distribution of the spray pattern, rather than the full cone spray pattern.
Spiral nozzle design is very natural, with anti clogging characteristics, but in the actual operation, should pay attention to the length of the nozzle selection criteria.
