Abstract
The utility model relates to an oxygen and liquid fuel atomizing and mixing mechanism for the welding and cutting torch. In a liquid fuel welding and cutting torch, the oxygen preheating tube is located in the liquid fuel tube, between the oxygen preheating tube and the liquid fuel tube is equipped with a passage connecting to the liquid fuel, the crossing of the oxygen preheating tube and the liquid fuel tube is a place for forming the mixed gas. No matter what the pressure of the liquid fuel is, the crossing of the oxygen preheating tube and the liquid fuel tube can be formed the mixed gas with good atomization, the burning is stable and the work is reliable.
Description
Technical field
The utility model relates to weldering, the cutting torch that uses liquid fuel, more particularly, relates to the oxygen of weldering, cutting torch and atomizing of liquid fuel, mixed organization.
Background technology
At present, use cutting torch, welding torch, the heating blowpipe of liquid fuel, the liquid fuel pipe on the body is contained in the preheat oxygen tracheae.The liquid fuel pipe is contained in the welding torch (comprising heating blowpipe) in the preheat oxygen tracheae, is by the control of the needle in operating liquid cartridge fuel delivery in use, and preheated oxygen comes out through the nozzle direct injection of preheat oxygen pipe front portion by opening valve rod.Because the liquid fuel pipe is contained in the stable negative pressure of the difficult formation of formed injection equipment in the preheat oxygen tracheae, the negative pressure of liquid fuel path is also less, be difficult to realize not having the fuel feeding of pressure, in use need adjust repeatedly oxygen, oil two valves just can make welding torch operate as normal, troublesome poeration not only, and being easy to generate the phenomenon of oil dripping, oil spout, cutoff, the preheat flame burning is stable inadequately, reliable, can influence normal flame operation when serious.
Summary of the invention
At the deficiencies in the prior art, the purpose of this utility model provides a kind of welding torch that uses liquid fuel, but forms stable negative pressure between its liquid fuel within pipe and the preheat oxygen tracheae.
The purpose of this utility model is achieved in that a kind of welding torch that uses liquid fuel, preheat oxygen pipe, liquid fuel pipe are arranged on the body, the preheat oxygen pipe connects oxygen valve, oxygen valve has joint, the preheat oxygen pipe is positioned within the liquid fuel pipe, between preheat oxygen pipe and the liquid fuel pipe passage that is connected liquid fuel is arranged, the intersection of preheat oxygen pipe and liquid fuel pipe has gaseous mixture to form the position, and gaseous mixture forms the position and communicates with the mouth joint.
On the such scheme basis, the utility model also has following further step:
Between described preheat oxygen pipe and the liquid fuel pipe accelerating jet is arranged.
Between preheat oxygen pipe and the liquid fuel pipe spiral accelerating jet is arranged.
It is bellmouth that described gaseous mixture forms the position.
On the bellmouth at described gaseous mixture formation position helicla flute is arranged.
Gaseous mixture forms the position and communicates with the mouth joint by injecting tube.
Advantage of the present utility model is as follows:
Because the preheat oxygen pipe is positioned within the liquid fuel pipe, between preheat oxygen pipe and the liquid fuel pipe passage that is connected liquid fuel is arranged, the intersection of preheat oxygen pipe and liquid fuel pipe has gaseous mixture to form the position, and gaseous mixture forms the position and communicates with the mouth joint.So, under the situation that liquid fuel within pipe and liquid-fuel tank are connected, only need the flow and the flow velocity of regulation and control preheated oxygen, can make oxygen gasification liquid fuel stably, and can form good mixing gas, oil, gas proportioning also can be controlled at good state automatically, no matter liquid fuel has or not pressure, the intersection of preheat oxygen pipe and liquid fuel pipe can both form wellatomized gaseous mixture.The utility model not only is applicable to welding torch and cutting torch, also is applicable to heating blowpipe, can regulate and control the size and the form of preheat flame easily, has flameholding, the advantage of reliable operation.
After taking further step, the utility model also has following advantage:
When between described preheat oxygen pipe and the liquid fuel pipe accelerating jet being arranged, liquid fuel can obtain quickening in passage.
When between preheat oxygen pipe and the liquid fuel pipe spiral accelerating jet being arranged, liquid fuel can obtain rotation and quicken in passage.
When described gaseous mixture formation position is bellmouth, can form stable negative pressure.
When on the bellmouth at described gaseous mixture formation position helicla flute being arranged, help strengthening the atomizing effect of gaseous mixture.
When gaseous mixture formation position communicates with the mouth joint by injecting tube, help further improving the quality of gaseous mixture.
