Abstract
The utility model discloses a long-pole preheating flame gun which comprises a long pipe that is provided with a valve used for controlling the flow rate of gas; a horn-shaped flame hole is arranged at the front end of the long pipe far from the valve; the surface of the horn-shaped flame hole is provided with a plurality of air inflow holes; and the caliber of the horn-shaped flame hole is larger than the pipe diameter of the long pipe. The long-pole preheating flame gun is simple in structure and lower in manufacturing cost; furthermore, when the long-pole preheating flame gun is in use, fire is not easily cut off, and the operation is very simple and safe.
Description
Technical field
The utility model relates to a kind of combustion tool, particularly a kind of stock preheating flame gun.
Background technology
The instrument that combustion gas and oxygen burn, weld, cut that utilizes that people are common has welding torch, cutting torch, blowtorch; For reaching the effect of welding and cutting; Must produce higher temperature, so the mist igniting that welding torch or cutting torch adopt pure oxygen and combustion gas to form is welded.The area of this welding torch or cutting torch bocca is less relatively, be not suitable for to the preheating of larger area metal, and welding torch, cutting torch adopts pure oxygen, and cost is also just higher, and the structure of welding torch or cutting torch is more complicated also.Generally adopt blowtorch for the metal preheating, and blowtorch is usually with diesel oil or gasoline as fuel, with Air pressurizer air mixed with gasoline or diesel oil and burn, its shortcoming is the frequent pressurization gas of needs, and the structure more complicated, and manufacturing cost is also better.
The utility model content
To the deficiency of above-mentioned prior art, the purpose of the utility model provides a kind of simple in structure, and cost is lower, is difficult for the stock preheating flame gun of cutoff.
To achieve these goals; The technical scheme that the utility model adopts is: this a kind of stock preheating flame gun; It comprises a long tube, and long tube is provided with the valve of control gas flow, and long tube is provided with tubaeform bocca away from the front end of valve; The surface of tubaeform bocca is provided with a plurality of air ostiums, and the bore of this tubaeform bocca is greater than the caliber of long tube.
Said long tube is provided with the fast-assembling interface away from an end of tubaeform bocca.
Said long tube is processed by copper pipe.
Adopt the stock preheating flame gun of technique scheme partly to be made up of valve, long tube and bocca three, simpler with respect to existing blowtorch, welding torch, cutting torch structure, cost is lower.The area of flame that bocca adopts tubaeform setting then to spray is bigger, and is just bigger with the contact-making surface of the object that needs preheating, helps carrying out preheating to the bigger object of area.Because the surface of tubaeform bocca is provided with air inflow aperture; When combustion gas when bocca burns, can produce bigger suction at air inflow aperture, air is sucked in the bocca continuously mixes mutually with combustion gas; Not only strengthen combustion intensity, and be difficult for cutoff.Long tube is provided with the fast-assembling interface away from an end of tubaeform bocca, conveniently is connected with gas pipeline or fuel gas bottle.
Compared with prior art, the utility model has the advantages that: this flame gun is not only simple in structure, and cost of manufacture is lower, and is difficult for cutoff, the also very succinct and safety of operation when using.
Description of drawings
Fig. 1 is the structural representation of the utility model.
The specific embodiment
To combine accompanying drawing that the utility model is described further below.
Referring to Fig. 1; The stock preheating flame gun of the utility model; It comprises a long tube 1, and long tube 1 is provided with the valve 2 of control gas flow, and long tube 1 is provided with tubaeform bocca away from the front end of valve 2; The surface of tubaeform bocca is provided with a plurality of air ostiums 11, and the bore of this tubaeform bocca is greater than the caliber of long tube 1.Said long tube 1 is provided with fast-assembling interface 12 away from an end of tubaeform bocca.Said long tube 1 is processed by copper pipe.
