Air atomizing nozzle

Abstract

An air atomizing nozzle comprises a nozzle body, a gas guide core, a jet nozzle, a locking nut, machining hole plugs and the like. The nozzle body is used for leading in pressurized liquid and gas and is used as an installation base body for the other parts. The gas is divided into two branches through the nozzle body. The gas can be led in a nozzle outlet mixing cavity from the second branch through the gas guide core and is then sprayed out. The jet nozzle is the last-layer part of the nozzle. The gas and the liquid are sprayed out of the jet nozzle after being mixed. The gas guide core and the jet nozzle are fixed to the nozzle body through the locking nut. The machining hole plugs plug outer holes left for machining inner holes of the nozzle body. The nozzle is a multifunctional gas atomizing nozzle; by means of the combined type structure, the nozzle can be changed into a two-time-mixing bubble type and pneumatic atomizing nozzle, a bubble type atomizing nozzle, a pneumatic atomizing nozzle and the like by changing the forms of the parts, and different atomizing effects can be achieved by changing sizes of through holes of all the parts.

Description

technical field [0001] The invention relates to the field of air atomization, and in particular belongs to a refined gas atomization nozzle, which can meet the special industrial requirements with higher requirements on the particle size and distribution of atomized liquid droplets. Background technique [0002] Atomizing nozzles are widely used, and can be said to run through the entire industrial and agricultural production, while gas atomizing nozzles are mainly used to produce very fine atomization effects. Current data show that gas atomizing nozzles include bubble atomizing nozzles, pneumatic atomizing nozzles, and Venturi atomizing nozzles. The air atomizing nozzle used in the icing wind tunnel spray system of China Aerodynamic Research and Development Center adopts the technology of American SPRAYING company. It is a two-stage pneumatic atomizing nozzle. The diameter of the atomized droplets, and the distribution is a normal distribution, but when the required dropl...
