Abstract
The utility model relates to a flame gun, characterizing in that the gun comprises a long tube which is equipped with a valve for controlling gas flux; a horn-shaped flame nozzle is arranged at the end of the long tube far from the valve; multiple air inlets are arranged on the surface of the horn-shaped flame nozzle; the diameter of the horn-shaped flame nozzle is greater than that of the long tube. The flame gun employing the technical scheme has a simple structure, low cost and uneasy fire cut-off in use.
Description
Technical field
The utility model relates to a kind of combustion tool, particularly a kind of flame gun.
Background technology
The common instrument that combustion gas and oxygen burn, weld, cut that utilizes has welding torch, cutting torch, blowtorch, welding torch is used for weld metal, cutting torch is used for cutting metal, 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, blowtorch is with diesel oil or gasoline as fuel, with Air pressurizer air mixed with gasoline or diesel oil and burns, and its shortcoming is the frequent pressurization gas of needs, and the structure more complicated, and manufacturing cost is also better.
The utility model content
The technical problems to be solved in the utility model provides a kind of simple in structure, and cost is lower, is difficult for the flame gun of cutoff.
For solving this technical problem, the technical solution adopted in the utility model is:
A kind of flame gun, it is characterized in that it comprises a long tube, long tube is provided with the valve of control gas flow, and long tube is provided with tubaeform bocca away from valve end, 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.
Described long tube is provided with screw thread away from an end of tubaeform bocca.
Described long tube is a copper pipe.
Adopt the spout rifle 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 screw thread away from an end of tubaeform bocca, conveniently is connected with gas pipeline or fuel gas bottle.
Description of drawings
Fig. 1 is the schematic diagram of the utility model flame gun.
The specific embodiment
Referring to Fig. 1, present embodiment relates to a kind of flame gun, it is made up of a brass long tube 1, the valve 2 and the tubaeform bocca 3 that are positioned on the long tube 1 the control gas flow, tubaeform bocca 3 surperficial equidistant is provided with a plurality of air ostiums 31, the bore of this is tubaeform bocca 3 is greater than the caliber of long tube 1, and long tube 1 is provided with screw thread 11 away from an end of tubaeform bocca 3.
Claims (3)
1, a kind of flame gun, it is characterized in that: 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 valve end, 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.
2, flame gun according to claim 1 is characterized in that: described long tube is provided with screw thread away from an end of tubaeform bocca.
3, flame gun according to claim 1 and 2 is characterized in that: described long tube is a copper pipe.
