The hollow cone nozzle features that it can produce hollow cone spray shape, the injection area is annular, and the spray distribution is even. The nozzle can spray small drops and has large and unblocked flow passage, eliminating the obstruction. The spray cap can be interchangeable in each tube of different dimension, and the nozzle cap also has a wide angle spray type.
A hollow cone nozzle sprays fluids in a ring-like pattern around a given radius, which produces a good interface between air and the surface of the droplets. When you require a small droplet size with capacity, these nozzles fill the bill.
The hollow cone spray type is essentially a circular liquid ring, which is usually formed by Flow chamber/cavity tangent at fluid inlet or an internal slotted blade which is close to the upstream of the nozzle orifice.
