31 the first compressed air streams being passed through drive, and under the effect of 23 inner wall of the first inward turning logical circulation road, form eddy flow.Liquid flow and the
One compressed air stream the first inward turning logical circulation road 23 carry out first time mixing, in the first inward turning logical circulation road 23 formed liquid flow with
The gas-liquid flow that first compressed air stream mixes, liquid flow complete primary atomization under the drive of compressed air stream.Gas-liquid flow
Entered in inward eddy room by the first inward turning logical circulation road 23 through the second inward turning logical circulation road, is sprayed by inward turning flow chamber nozzle.
Since the setting of second gas inlet 32 is in access 3 side wall of seat, the second compression being passed through by second gas inlet 32 is empty
After air-flow enters the first outward turning logical circulation road 24, enters in contour stealth room through the first outward turning logical circulation road, the second outward turning logical circulation road and formed
Eddy flow, the gas-liquid flow that internal spin chamber's nozzle sprays are atomized again.Liquid flow atomizing effect through being atomized twice is very good,
Not tube liquid runoff size can all make liquid stabilising in a good spray pattern.And it can be very square according to the needs of client
Just atomizing effect is adjusted.Due to its atomization angle is big, uniform tapered veil the advantages of, be used in pharmacy, food and chemical industry granulation,
Atomizing effect used in pill and coating equipment in sugar production line is highly desirable, exactly they need spray gun, be greatly improved production efficiency and
Product quality.
