Abstract

The utility model relates to a multifunctional cutting and welding nozzle which is composed of a housing body, a core barrel and a gasification sleeve, wherein, the outer margin of the gasification sleeve is provided with a passage. The gasification sleeve is arranged out of the core barrel and in the housing body. The utility model has multiple functions, and the utility model can use gas (propane) and gas (oxygen) and can be also suitable for liquid and gas (oxygen). The application range of the cutting and welding nozzle is widened.

Description

Multi-functional cutting and welding torch-tip

The utility model relates to a kind of multi-functional cutting and welding torch-tip, mainly supplies the usefulness of flame cutting and welding.

Prior art is the cutting and welding torch-tip of oxygen and propane flammable gas, is made up of housing 1 and core tube 2.Housing top inner chamber has import 4, the usefulness that supplies propane flammable gas to enter.The usefulness that core tube inner chamber oxygen supply gas passes through.

The purpose of this utility model is to overcome above-mentioned weak point of the prior art and provides a kind of while can use the multi-functional cutting and welding torch-tip of gas (oxygen) gas (propane) or gas (oxygen) liquid.

The purpose of this utility model can reach by following measure: the utility model is made up of housing, core tube and gasifying sleeve, and the gasifying sleeve outer rim has passage, and gasifying sleeve is loaded in the outer and housing of core tube.

The passage of gasifying sleeve outer rim has narrow ring and vertical bar shaped, spiral bar shaped or spiral vertical bar combination shape.

The drawing of accompanying drawing is described as follows:

Fig. 1 always schemes for broken section of the present utility model; Right half of gasifying sleeve does not cut, and represents the combination passage of narrow annular and vertical bar shaped;

Fig. 2 is the utility model gasifying sleeve outline drawing, the structure of expression thread-shaped passage;

Fig. 3 is the utility model gasifying sleeve outline drawing, the structure of expression spiral vertical bar combination shape passage.

The accompanying drawing piece number is represented:

1, housing 2, core tube 3, gasifying sleeve 4, import

5, light beam tube 6, narrow annular 7, vertical bar shaped 8, thread-shaped

The utility model is described in further detail below in conjunction with embodiment and accompanying drawing:

Fig. 1 represents structure of the present utility model, is made up of housing 1, core tube 2 and gasifying sleeve 3, and housing and core tube are same as the prior art.

Gasifying sleeve 3 is cover shape structure, is loaded on the below of import 4 between housing and the core tube.The gasifying sleeve inner chamber is set in outside the core tube, and the gasifying sleeve cylindrical is loaded in the shell.The effect of gasifying sleeve is that the liquid that enters from import 4 (as gasoline) fuel is gasified, after logical oxygen and igniting, housing and gasifying sleeve all are preheated, and the passage of adding between gasifying sleeve and housing is a narrow slit, both actings in conjunction are gasified the liquid by passage.Warp and oxygen mix after-combustion obtain the flame of high temperature, so that workpiece is cut and welds.Certainly can also adopt the propane flammable gas and the oxygen of prior art, to carry out flame cutting and welding.

The structure of passage and shape have following three kinds:

What Fig. 1 represented is: gasification pot cylindrical top is the external diameter light beam tube 5 littler than housing inner chamber internal diameter, and airway is narrow by annular 6.Gasification pot bottom cylindrical is a spline shape, and airway is a vertical bar shaped 7, makes groove the spline leave with rage from advancing 4 liquid that come out.

What Fig. 2 represented is the thread-shaped 8 of rectangle, and liquid is made passage between screw thread leave with rage.

What Fig. 3 represented is: gasification pot cylindrical top is the thread-shaped 8 of rectangle, and the bottom is a vertical bar shaped 7.

The utility model contrast prior art has following advantage:

Function is many, and both available gas (propane), gas (oxygen) were applicable to again liquid, gas (oxygen) has widened the range of application of cutting torch.

Claims

1, a kind of multi-functional cutting and welding torch-tip comprises housing and core tube, it is characterized in that, also comprise gasifying sleeve, the gasifying sleeve outer rim has passage, and gasifying sleeve is loaded in the outer and housing of core tube.

2, multi-functional cutting and welding torch-tip according to claim 1 is characterized in that, the passage of gasifying sleeve outer rim has narrow ring and vertical bar shaped, spiral bar shaped or spiral vertical bar combination shape.
