The utility model relates to a metal welding torch capable of using many kinds of gas and liquid fuel, which is composed of a filtering core, a regulating valve, a welding nozzle, an inner nozzle, a welding seat, a flow deflection barrel, etc. The utility model is characterized in that the center of the welding nozzle is provided with a through hole, the center of one end of the through hole is provided with a mixing chamber, and an annular slot is arranged out of the mixing chamber and is respectively corresponding to and matched with the inner nozzle and the flow deflection barrel on the welding seat. The welding nozzle and the welding seat are connected by threads. When the utility model works, liquid fuel is conveyed to the metal welding torch by a fuel pot, and is deflected in the annular slot through the filtering core, the regulating valve, an oil gas conduit and the welding nozzle. The utility model utilizes self residual heat to cause the liquid fuel to be gasified, and the gasified liquid fuel and oxygen are mixed in a mixing chamber to generate high temperature flame.

Description

Can use the metal solder torch of multiple gas, liquid fuel

The utility model is a kind of metal solder torch, and it can use multiple gas, liquid fuel to carry out metal solder, hot melt, heated baking etc.Belong to metal solder equipment field.Being widely used for the processing and manufacturing of plant equipment etc., is factories and miness, enterprise and the indispensable important tool of metal processing manufacturing industry.

The metal solder torch of Shi Yonging in the prior art generally is to be welding energy with oxygen and acetylene gas, and it is made up of oxygen cylinder, acetylene cylinder, airline hose and welding torch.Small part user scene is the electricity consumption acetylene gas of getting made of stones still, not only dangerous big but also contaminated environment.General problem is to use the cost height, and volume is big and heavy.Remote districts acetylene gas source inconvenience.

The purpose of this utility model is a kind of natural gas, liquefied gas, metal welding/cutting gas, light oil, gasoline, kerosene, diesel oil and other combustible gases, the liquid medium of using that designs for the deficiency that overcomes existing oxy-acetylene welding, all can use as welding energy.Suit measures to local conditions to gather materials on the spot, the high acetylene gas of displacement cost easily is to reduce use cost.

The new purpose of this practicality can be achieved through the following technical solutions: it is crossed filter core, gas liquid fuel control valve, gas-liquid conduit, weldering seat, inner nozzle, baffling tube and tip etc. by handle and forms.Oxygen is entered arm on the handle of welding torch through airline hose by oxygen cylinder, enter inner nozzle by conduit and weldering seat behind oxygen regulating valve, ejects oxygen to mix the liquid fuel after the vaporization; Liquid fuel enters handle back seat joint by the low-pressure fuel jar through conveying rubber pipe and enters the weldering seat through filter core, fuel control valve, conduit again, baffling tube baffling in the tip cannelure absorbs the tip heat and makes liquid fuel evaporation again, mix with oxygen spray in tip the vaporization back, and burning produces high-temperature gas and welds.Liquid fuel is tortuous circuitous in tip, and the temperature when borrowing tip self work first makes liquid fuel evaporation, second can reduce the temperature of tip, plays cooling effect.When selecting gaseous fuel for use, gas gives the direct and oxygen mix burning in heat back by the baffling tube, produces high-temperature gas, and can improve efficiency of combustion, metal is welded or toasts, hot melt etc.

This metal solder torch can use multiple gas, liquid fuel to do the energy.According to measuring and calculating, when every welding torch welds with the gasoline replace ethine, can save 70 yuans every day, can save about 20,000 yuan for annual every, if promote the use of in the whole nation, it will be bigger saving number, social benefit is more remarkable.If suit measures to local conditions to adopt gas-liquid fuel, reduction effect is more obvious.Above-mentioned lease acetylene gas bottle and the freight of also not comprising.Applying unit is gathered materials on the spot, and can save a large amount of expenses, and In-particular is just much convenient with outlying isolated area.As long as possess one of above-mentioned several energy, save and purchase acetylene gas, lease acetylene cylinder, expenses such as transportation.

This metal solder torch adopts the grasp custom and the mode of operation of spreading, and needn't special training can skillfully operate the sorrow that does not have tempering safe in utilization.

This welding torch structure adopts the self-heating gasifying mode, and the fuel that enters is first given the heat vaporization.Second can effectively reduce the temperature of welding torch, work long hours, can not cause the hot and tempering problem of welding torch heating.With the matching used low-pressure fuel jar of metal solder torch, be exclusively used in storage and charge, and fuel is transferred to the metal solder torch, and dispose the pressure limiting inflator, oil filler, safety valve, liquid valve etc. with certain pressure.

Application below in conjunction with 1 pair of this utility model of accompanying drawing simply shows with calcspar earlier, and then describes in further detail with accompanying

2 pairs of metal solder torches are described further in conjunction with the accompanying drawings: oxygen enters going up of handle back seat (17) and handle pipe (11) from joint (14) and manages, and after control valve (10) enters conduit (9) and goes up pipe, this is after weldering seat (7) enters inner nozzle (6); Liquid fuel enters the following pipe of handle pipe (11) through filter core (16) from joint (15), enter pipe under oil, the airway (9) and enter weldering seat (7) through control valve (18) again, after this enter in the cannelure of tip (5), vaporization after the heat absorption of baffling tube (8) baffling, fuel after the vaporization enters in the mixing chamber that inner nozzle (6) locates, fully mix back ejection burning with oxygen, produce thermal-flame, to be used for welding processing etc.

3 pairs of low-pressure fuel jars are described further in conjunction with the accompanying drawings: (19) are tank body among the figure, liquid fuel adds from adding inlet (24), guard (25) is with fuel filter after filtration, and complete back pressurizes, forces fuel to flow to the metal solder torch through drain pipe (26) and fuel outlet valve (22) by pressure limiting inflator (20).Pressure limiting inflator (20) will show pneumatic tube piston rod (21) to make hollow form for limiting maximum working pressure, forming clearance volume, because the existence of clearance volume, can be conveniently under the pressure of setting inflate pressurization for fuel tank.But limit pressure if be higher than this, the gas in the clearance expands when piston is air-breathing, forms expansion → compression → expansion ... gas can't be pressed in the jar, guarantee tank body safety within limits thereby limit pressure.Safety valve (23) is to cause overpressure protection apparatus for preventing because of reasons such as temperature rises.
