Abstract

The utility model relates to the improvement of acetylene and gasoline welding and cutting equipment, and is a novel hand holding type welding and cutting torch using gasoline as fuel, which is characterized in that a voltage stabilizer and a mixing device are arranged in a gasoline pipe and at a gasoline and gas mixing position. The head part of a welding and cutting nozzle is provided with a mixing flash chamber. The utility model has advantages of simple structure, easy fabrication, low cost, convenient operation and high safety. When the utility model is used, the operating method of the existing welding and cutting torch is not changed. The utility model can cut, can also weld 0.5 to 5 mm thin plates, and can carry out soldering and brazing.

Description

Handle type gasoline welding, cutting torch

The utility model relates to the improvement to the acetyl gasoline welding and cutting device, is a kind of novel handle type gasoline welding, cutting torch.

The conventional tool of metal welding is to be the welding torch of fuel with acetylene or propane or liquefied petroleum gas, and acetylene, propane cost are higher, and transportation and storage is difficulty relatively, and security is relatively poor.At present, domestic a lot of manufacturer production gasoline welding cutting torches, the problem that the ubiquity combustibility is bad, its welding torch can not weld thin plate, more can not carry out soldering and brazing, also having a common shortcoming is that contour structures and acetylene welding cutting torch difference are very big, and it is uncomfortable that the user feels.

The purpose of this utility model provides a kind of based on existing acetylene welding cutting torch, can overcome handle type gasoline welding, the cutting torch of above-mentioned shortcoming.

The technology contents of the utility model handle type gasoline welding, cutting torch is summarized as follows:

A kind of handle type gasoline welding, cutting torch, based on existing acetylene welding cutting torch, by welding chew, pressure cap, oxygen tube junction, mixing oxygen valve and petrol union form, it is characterized in that: in gasoline pipe, stable-pressure device and mixing arrangement are housed, chew head at welding and be provided with the mixing flash chamber with oil gas mixing position.

The utility model has the advantages that: simple in structure, easy manufacturing, cost be low, esy to use, safe and reliable, do not change former acetylene welding cutting torch when using method of operating, can cut, also can weld the thin plate of 0.5-5mm, can carry out soldering, brazing.

Provide embodiment of the present utility model below in conjunction with description of drawings:

Fig. 1 is structural representation I of the present utility model

Fig. 2 is the structural representation of the mixing flash chamber of structural representation I of the present utility model

Fig. 3, Fig. 4 are the stable-pressure device of structural representation I of the present utility model and the structural representation of mixing arrangement.

Fig. 5 is structural representation II of the present utility model

Fig. 6 is the structural representation of the mixing flash chamber of structural representation II of the present utility model

Fig. 7, Fig. 8 are the stable-pressure device of structural representation II of the present utility model and the structural representation of mixing arrangement.

Fig. 1, among Fig. 2,1-cuts and chews, 2-pressure cap, 3-gasoline stable-pressure device, 4-oxygen oil mixing apparatus, 5-oxygen connection, 6-mixing oxygen valve, 7-gasoline joint.

See Fig. 1, Fig. 5, with oil gas mixing position stable-pressure device 3 and mixing arrangement 4 are housed in gasoline pipe, the function of stable-pressure device 3 is: when operation, when the welding torch need be held high, gasoline is unlikely because deadweight sinks to causing the unstable or fire extinguishing of flame size, makes the flame can continuous burning.The effect of mixing arrangement is that oil gas is mixed, and lays a solid foundation for fully burning.Stable-pressure device 3 is conglobate shape or metal powder powder, mixing arrangement 4 is net form (seeing Fig. 4 or Fig. 7) or capillary tubular (seeing Fig. 3 or Fig. 8), chew head at welding and be provided with mixing flash chamber (seeing Fig. 2 or Fig. 6), welding is chewed the dilatation mixing shape that head dimensions is Φ 4-12mm * 1-5mm.

Claims

1. a handle type gasoline welding, cutting torch, based on existing acetylene welding cutting torch, by welding chew, pressure cap, oxygen tube junction, mixing oxygen valve and petrol union form, it is characterized in that: in gasoline pipe, stable-pressure device and mixing arrangement are housed, chew head at welding and be provided with the mixing flash chamber with oil gas mixing position.

2. handle type gasoline welding according to claim 1, cutting torch, it is characterized in that: stable-pressure device 3 is conglobate shape or metal powder powder, mixing arrangement 4 is that net form or capillary are tubular, chew head at welding and be provided with the mixing flash chamber, welding is chewed the dilatation mixing shape that head dimensions is Φ 4-12mm * 1-5mm.
