Abstract
The utility model relates to a fuel gas burner for welding, particularly a portable gas welding unit. The portable gas welding unit comprises a gas storing device, a working part and an oxygen supplying part, wherein, the working part comprises a flammable gas adjusting valve, an oxygen adjusting valve, a mixed connecting body, a mixed jet pipe and a welding nozzle. Because a gasifier is arranged in the gas storing pot body and a flash-back preventer is arranged in the flammable gas adjusting valve body, the utility model has the characteristics of reasonable structure, safe use, ease processing, low cost, convenient assembly and maintenance, and easy carrying, etc.
Description
The utility model belongs to the gaseous fuel burners that welds usefulness, particularly a kind of portable gas welder.
At present, gas welding unit and equipment that industry all departments use normally are made up of acetylene generator, flash-back arrestor, oxygen cylinder, pressure reducer, welding torch, rubber tube, because acetylene generator, oxygen cylinder volume are big, relatively heavier, be difficult for carrying, open-air and high-altitude welding and electric appliances service and smallclothes are approached the welding of part etc., bring many difficulties, thereby influence its application.Chinese patent CN86210798 number a kind of portable practical gas welder is disclosed in the recent period, it comprises welding torch, breathing equipment two parts, and wherein welding torch is made up of welding torch body, imflammable gas control valve, oxygen regulating valve, concentrated imflammable gas holder, adapter sleeve and the flap valve of piece connection in twos.Owing to this gas welder is not provided with fireproof tempering device, in case tip stops up, concentrate the interior liquid stock of flammable gas tank and become to the greatest extent, liquid state weakens to the dynamic balancing pressure of liquid state to gas and gas, and oxygen will flow backwards and easily set off an explosion in air accumulator; Concentrate no gasification installation in the imflammable gas air accumulator, oxygen bag does not have the pressure regulation backstop, causes imflammable gas to enter in the mixing tube and oxygen mix with liquid state, in case tip stops up, the pressure that the imflammable gas of liquid state forms can make it flow backward in the oxygen bag, also sets off an explosion easily; When being lower than burning velocity along with the continuity gas flow rate of working time in addition, tempering phenomenon can take place, gently then burn out the oxygen bag, heavy then cause an explosion accident.
The utility model improves at the problem that prior art exists, and provides a kind of rational in infrastructure, safe and reliable, processing easily, and cost is low, assembling and portable gas welder easy to maintenance.
The utility model is achieved by following manner: a kind of portable minisize gas welding torch, comprise caisson, working portion, the oxygen supply part, caisson is by the gas storage tank body, the tank body coupling sleeve, bottom end cover, the sealing ring V, inlet valve complement and base are formed, working portion comprises the imflammable gas control valve, oxygen regulating valve, mix connected body, mixing jet pipe and tip, the oxygen supply part is by oxygen cylinder, bridge, compositions such as pressure regulator, technical characterictic of the present utility model is that gasifier and flash-back arrestor are set, promptly in the gas storage tank body, gasifier is set, above-mentioned gasifier has a vapor lamp in the air accumulator body that links with the imflammable gas regulation valve body and enter, the vapor lamp lower end is provided with gasifying sleeve, which is provided with the gasification hole; Simultaneously, in the imflammable gas regulation valve body flash-back arrestor is set, it has a flash-back arrestor main body, is provided with pressure adjustment screw and rupture pressure disc at its front end, and the flash-back arrestor main body is made up of foam, silk screen, packing ring.In addition, above-mentioned imflammable gas control valve is made up of imflammable gas regulation valve body, needle, knob, escape pipe, the valve rod of giving vent to anger, sealing ring, the valve rod of giving vent to anger, gas accelerator, the spool of giving vent to anger, the valve pocket of giving vent to anger.Oxygen regulating valve is made up of oxygen regulating valve body, oxygen valve joint needle, oxygen regulating valve knob.In addition, be provided with the mixing connected body, mix connected body and form by a coupling sleeve, coupling sleeve sealing ring at the oxygen regulating valve front end.Be provided with sealing ring and connecting firmly in it, connect on the screw and be shaped on T type hole and ring shaped slot, be shaped on inclined hole on the coupling sleeve and be communicated with T type hole and cannelure on the connection screw with the connection screw.
The utility model is compared with prior art, has that simple in structure, safe and reliable, processing and manufacturing and assembling are comparatively simple and easy, maintenance and characteristics such as easy to carry.
