Abstract
The utility model relates to a petrol-oxygen cutting and welding atomizer, which is composed of an atomizer body, a petrol inlet, a preheating oxygen inlet, a petrol tubule and a preheating oxygen tubule. The petrol tubule enter the preheating oxygen tubule in the atomizer body, the oxygen energy cause the petrol sent by the petrol tubule to be sprayed into thin mist so as to enter the cutting nozzle of the cutting torch, and the oxygen and the petrol after atomizing can be sufficiently mixed for getting ideal flame. The utility model can be matched with cutting torches and can be arranged in a cutting nozzle joint or a preheat oxygen pipe, or the utility model can be arranged in the cutting torch of a self-automatic cutting machine for improving operating condition.
Description
The utility model relates to a kind of gasoline-oxygen gas cutting and welding atomizer, belongs to the Machining Technology field.
At present, the gasoline-oxygen cutter that is designed by the inventor can cut the steel of 300 millimeters thick, and can burrow in the middle of the steel plate of 80 millimeters thick.This gasoline cutting machine is made up of cutting torch, special-purpose isobaric cutting torch, voltage stabilizing feed tank etc., and the patent No. is ZL92225731.0, ZL92244852.3, ZL94247487.2.The shortcoming of above-mentioned patent is, because the atomizing of gasoline is to carry out in cutting torch, narrow atomization space and blending space make the cutting slab and fuel delivery need be strengthened the time, atomization badness occurs, the Mars that promptly has little oil droplet to generate in the flame.In addition on cutting torch and the cutting torch cutting torch joint be connected that the cone match that is by three 30 realizes, the conical surface loose contact that often has in use and produce and collaborate, go here and there oily phenomenon worsens operating mode, flame is strong inadequately.
The purpose of this utility model is design a kind of gasoline-oxygen gas cutting and welding atomizer, the energy that utilizes oxygen is gasoline atomizing, and this atomizer is fixed in torch head or the preheat oxygen pipe, to improve the gasoline atomizing level, thereby acquisition sufficient combustion, flame are concentrated, and regulate being easy to desirable flame.
Gasoline-oxygen gas cutting and welding the atomizer of the utility model design is made up of atomizer body, gasoline inlet, preheat oxygen import, gasoline tubule and preheat oxygen tubule.The preheat oxygen tubule communicates with the preheat oxygen import, and the diameter of preheat oxygen tubule is 0.5～2.5 millimeter; One end of gasoline tubule communicates with gasoline inlet, and the other end communicates with the preheat oxygen tubule, and the gasoline tubule enters the thin oxygen pipe of preheating at distance atomizer end face H=0.5～3 millimeters places, and the diameter of gasoline tubule is 0.5～0.8 millimeter.For gasoline is fully atomized, the outlet of the preheat oxygen tubule of atomizer is designed to taper, the angle [alpha] of the conical surface=15 °～60 °
Use the atomizer of the utility model design, can utilize the energy of oxygen that gasoline is fully atomized, make gasoline and the abundant blending of oxygen after the atomizing again, just can obtain desirable flame.This atomizer is fixed in cutting torch head or the preheat oxygen pipe, can improves the gasoline atomizing level greatly, thereby obtain sufficient combustion, concentrated, the easy desirable flame of adjusting of flame.
