Abstract
The utility model relates to an automatic lighting gas welding gun. A gun body (1) is provided with an igniter (3) of which a control switch (4) is bulged out of the surface of a handgrip. The igniter (3) is provided with an electrical discharge wire (6) of which the discharging terminal is arranged at the position next to the outlet terminal of a cutting nozzle (7). An igniter gas tube (5) communicated with the gas path is arranged on the gun body (1), and the outlet of the igniter gas tube (5) is corresponding to the discharging terminal of the electrical discharge wire (6). With rational design, convenient ignition, raised safety performance and work efficiency, simple structure, easy rebuilding and production of welding guns, very little increasing cost, and easy implementation, popularization and application, the utility model is a novel, convenient and practical welding cut bit.
Description
Technical field
The utility model relates to a kind of combustion gas welding cut bit, particularly a kind of automatic igniting fuel gas welding torch.
Background technology
Fuel gas welding torch is more extensive in industrial application, utilizes the burning torch heat fused metal of combustion gas, both can be used as cutting tool hardware is carried out cutting and separating, also can be used as soldering appliance hardware is welded fastening being connected as a single entity.Because existing welding gun needs the manual firing, in the time of use, a hand to take welding gun, the igniting of another hand, very inconvenience, and be subjected to climatic effect, and bigger at wind-force, be difficult to igniting, influence operating efficiency.Particularly when work high above the ground, as the improper certain danger that also exists of lighting a fire.
Summary of the invention
The purpose of this utility model is to overcome the shortcoming of above-mentioned prior art and a kind of improved automatic igniting fuel gas welding torch is provided, and convenient igniting and use are increased work efficiency.
The purpose of this utility model can realize by following technical measures: this fuel gas welding torch is improved on the basis of prior art and is formed, comprise handle, rifle body, nozzle, on the rifle body, be provided with igniter, igniter is installed in the handle, its gauge tap is given prominence in handle surfaces, igniter has picked out electrical discharge wire, the discharge end of electrical discharge wire is located near the jet expansion end position, can directly light a fire to nozzle, also can establish in addition with the rifle body in the igniting tracheae of combustion gas channel connection, the corresponding igniting of discharge end of the outlet of igniting tracheae and electrical discharge wire.
The utility model is reasonable in design, sets up igniter on the rifle body, and the operation igniting is convenient, has improved security performance and operating efficiency, the convenient use, it is simple in structure, and welding gun transformation and production are easily, it is few to increase cost, and implement and apply easily, be the welding cut bit of a Nover practical.
Description of drawings
Fig. 1 is a structure chart of the present utility model.
The specific embodiment
With reference to Fig. 1, this fuel gas welding torch comprises the handle [2] on rifle body [1] and the rifle body, nozzle [7], on rifle body [1], be provided with ignition [3], also can be piezoelectric ceramic ignitor, ignition [3] is contained in handle [2] the inside, outside the outstanding handle surfaces of its gauge tap [4], gauge tap [4] is a contact switch, also gauge tap can be set as with burnt gas switch and link, connect gauge tap when opening burnt gas switch, realize igniting automatically, ignition [3] is connected to electrical discharge wire [6], the discharge of electrical discharge wire [6] is terminal facing to nozzle [7] port of export, the igniting tracheae [5] that is communicated with blast tube is arranged on rifle body [1], and igniting tracheae [5] outlet is terminal corresponding with the discharge of electrical discharge wire [6], can on igniting tracheae [5] ball valve be set, conveniently open and close, reduce gas loss.Acetylene is preferably adopted in its combustion gas of this fuel gas welding torch.During use as adopting acetylene as combustion gas, the acetylene joint and the oxygen connection of this fuel gas welding torch are connected with acetylene cylinder and oxygen cylinder respectively, open acetylene cylinder and oxygen cylinder, respectively oxygen valve on the welding gun and acetylene valve are opened afterwards, emit an amount of oxygen and acetylene, press gauge tap [4] then, the discharge end of electrical discharge wire [6] emit spark, the acetylene that firing point internal heat pipe [5] comes out, the mist that nozzle [7] comes out is lighted simultaneously, at this moment, can carry out the welding operation.
Claims (1)
1, a kind of automatic igniting fuel gas welding torch, comprise rifle body [1], handle [2], nozzle [7], it is characterized in that in rifle body [1], being provided with igniter [3], outside the outstanding handle surfaces of its gauge tap [4], igniter [3] is connected to electrical discharge wire [6], the discharge end of electrical discharge wire [6] is located near cutting torch [7] port of export position, is provided with the igniting tracheae [5] that is communicated with blast tube on rifle body [1], and igniting tracheae [5] outlet is terminal corresponding with the discharge of electrical discharge wire [6].
