Abstract
The utility model relates to a portable double-jet welding gun which uses butane as the fuel and belongs to the field of the welding tool of flames, comprising a forcipate double-jet welding tip, a nozzle, an air blender, a laval nozzle and a liquid storing bottle. Guide blades are arranged respectively in the welding tip, the bottom part of the liquid storing bottle is provided with a liquid charging valve, and the upper part is provided with a pressure regulating valve. The utility model has the advantages of compact structure, convenient operation, convenient portability, delicate external form and good welding effect, and steel tubes with phi 3-phi 16 can conduct the burning silver soldering.
Description
The utility model relates to the flame welding bonding tool, and particularly a kind of is the welding gun of fuel with the butane.
At present, the employed soldering appliance of refrigerator repairing trades mostly is traditional gas welding unit, promptly has the gas welding torch of acetylene generator and oxygen cylinder, this gas welding unit heaviness, and can not solve registers one's residence repairs the problem of refrigerator; And other adopts the welding gun of fuel gas such as liquefied petroleum gas, coal gas, and effect is still undesirable when the connecting tube of welding refrigerator.
The purpose of this utility model is that a kind of simple in structure, processing ease of specialized designs, welding effect are good in order to address the above problem, and soldering appliance easy to carry, provides convenience for the refrigerator maintenance personal makes house calls.
Design of the present utility model is: it is made up of torch head, injector and device for storing liquid three parts, and whole welding gun is the pistol shape.Torch head adopts the structure of twoport rifle mouth.Injector has comprised nozzle, air mixer and De Laval noz(zle).Wherein an end of De Laval noz(zle) is connected with the stubborn and reluctant property of twoport rifle, and the other end adopts engage thread to be connected with air mixer.The hollow space of air mixer is provided with nozzle, and its diameter is at 0.2m～0.5mm.Device for storing liquid is made of liquid storage bottle, liquid-filling valve, pressure regulator valve and control valve, and liquid-filling valve is located at the bottom of liquid storage bottle, is used for pouring into fuel; Liquid storage bottle center upper portion position is equipped with pressure regulator valve, and the pressure regulation side of valve body is connected with a control valve, and application valve body adopts with air mixer and is threaded.During welding, liquid storage bottle is promptly as the handle of holding.
The twoport rifle mouth of this welding gun is designed to pincer, can make welded pipe at the whole garden at weld bond place side face thermally equivalent, thereby shorten heat time heating time, and welding effect is good.In two rifle mouths, also be respectively equipped with guide vane, can make mist form a recirculating zone that is included in jet inside at the muzzle place, in combustion process, this recirculating zone impels a large amount of high temperature gases recirculatings to the torch root, thereby guarantees that fuel burns fully.For preventing to leak, be respectively equipped with sealing ring in the junction, two places of application valve body and air mixer, pressure regulator valve.
The utility model has following advantage compared with similar products:
1, simple in structure, small and exquisite, easy to operate, be easy to carry.Particularly solving registers one's residence repairs the Welding Problems of refrigerator.
2, the flame of twoport rifle mouth injection can surround the whole garden week of weld bond place tube connector effectively, makes it to be heated evenly, thereby shortens weld interval, guarantees welding quality.
3,, make the fuel availability height, flame stabilization because reasonable in design.
Embodiment of the present utility model is illustrated with reference to accompanying drawing.
Fig. 1 is the structural representation of embodiment.
Wherein: 1-twoport rifle mouth; The 2-De Laval noz(zle); The 3-air mixer; The 4-control valve; The 5-liquid storage bottle; The 6-nozzle; The 7-pressure regulator valve; The 8-liquid-filling valve; The 9-guide vane.
The cross-sectional diameter of the twoport rifle mouth (1) in the present embodiment is 12mm, and the angle of the extended line of the center line of two rifle mouths is 60 °.
The using method and the performance of present embodiment are as follows: earlier fuel-butane is poured in the liquid storage bottle (5) by liquid-filling valve (8), once can stores about liquid 75 grams.Open pressure regulator valve (7) and control valve (4), hold liquid storage bottle (5) middle part and weld, according to the difference of environment for use temperature; Can regulate pressure regulator valve (7) and control valve (4) at any time, make flame reach optimum state.General flame of centre temperature can reach 1400 ℃, only needed 1～3 minute the weld interval of each interface and weld bond firm.
Claims (3)
1, a kind of pair of mouth portable gun welder comprises torch head, and injector and device for storing liquid is characterized in that torch head adopts the structure of twoport rifle mouth; Injector is made up of nozzle, air mixer, De Laval noz(zle), and De Laval noz(zle) one end is connected with the stubborn and reluctant property of twoport rifle, and the other end and air mixer are by being threaded, and the hollow part of air mixer is provided with a nozzle; Device for storing liquid comprises liquid storage bottle, liquid-filling valve, pressure regulator valve, control valve, and liquid storage bottle bottom is equipped with liquid-filling valve, and the center upper portion position has pressure regulator valve, and pressure regulator valve valve body side is connected with a control valve, and application valve body and air mixer are with being threaded.
2, according to claim 1 pair of mouth portable gun welder is characterized in that described twoport rifle mouth for pincerlike, is equipped with guide vane in each rifle mouth.
