Abstract

The utility model relates to a gasoline welding torch, which solves the technical problems of inhomogeneous gasoline atomization, easy generation of oil leakage, oil dripping, etc. existed in the existing gasoline welding torch. In order to solve the technical problems, the utility model comprises a welding nozzle with an internal nozzle. The utility model is characterized in that the internal nozzle of the welding nozzle is provided with annular blades arranged at intervals, and every blade is provided with a gap. All gaps are arranged in obliquely spiral shape along the axis direction. Due to the adoption of the structure, the blades can stop the ejective gasoline which is not yet atomized so as to solve the problems of oil dropping and oil leaking, and in addition, after dropped onto the blades, the gasoline which is not yet atomized goes along the spiral gaps to extend a gasoline path. The gasoline path is increased from 50.5 mm to 333 mm to cause the gasoline and oxygen gas to be thoroughly mixed so as to achieve better atomization effect and stable combustion.

Description

Gassline welding torch

Technical field

The utility model relates to a kind of Gassline welding torch, specifically to having a kind of improvement of Gassline welding torch now.

Background technology

Gassline welding torch commonly used at present is to utilize oxygen, gasoline to weld through oxygen and the gasoline combustion gas that forms after mixing, preheating time is short, and speed of welding is fast, but the ubiquity gasoline atomizing is inhomogeneous, atomizing particle is bigger, shortcoming such as easily produce leakage of oil, oil dripping, cutoff, breathe, and insufficient instability of burning easily cause energy waste, contaminated environment is comparatively serious, have the tip of being exactly easily to tie carbon again and stop up, the life-span is lower, thereby causes unnecessary economic loss.

Summary of the invention

The utility model is inhomogeneous for the gasoline atomizing that solves existing Gassline welding torch existence, easily produces technical problems such as leakage of oil, oil dripping.

In order to solve the problems of the technologies described above, the utility model comprises tip, and tip comprises interior mouth, it is characterized in that mouth is provided with spaced annular blade in the tip, has a breach on the every blade, and institute is jagged to be the arrangement of inclined screw shape along axis direction.

The utlity model has following advantage and good effect: because the utility model is provided with spaced annular blade on the mouth in tip, can stop the gasoline of atomizing not as yet of ejection, solve droplet, the leakage of oil problem; In addition owing to have a breach on every blade, institute is jagged to be the arrangement of inclined screw shape along axis direction, after the gasoline of atomizing does not drip on the blade as yet, walk downwards along spiral helicine breach, prolonged the gasoline path, be increased to 333mm, made gasoline fully mix with oxygen by 50.5mm, thereby reach good atomizing effect, and burning is more stable.

The specific embodiment

Referring to Fig. 1～Fig. 5, the utility model comprises that tip 1, tip comprise interior mouth 7, is provided with spaced annular blade 8 in tip on the mouth 7, has a breach 9 on the every blade 8, institute jagged 9 is the inclined screw shape along axis direction arranges, and has prolonged the gasoline path widely.

Certainly, above-mentioned explanation is not to be to restriction of the present utility model, and the utility model also is not limited to above-mentioned giving an example; those skilled in the art; in essential scope of the present utility model, the variation of making, remodeling, interpolation or replacement also should belong to protection domain of the present utility model.

Claims

1, a kind of Gassline welding torch, it comprises that tip, tip comprise interior mouth, is characterized in that: mouth is provided with spaced annular blade in the tip, has a breach on the every blade, and institute is jagged to be the arrangement of inclined screw shape along axis direction.
