Abstract

The utility model relates to an oxygen spraying gasoline cutting and welding gun, which is composed of a gun handle, a gun body and a gun head, wherein, the gun handle is the same with the gun handle of the existing cutting and welding gun. The gun body is provided with a high pressure oxygen pipe, and a low pressure oxygen tube and a gasoline tube, and a gun head body is arranged on the gun head. The inner part of the gun head is provided with a high pressure oxygen through tube, a high pressure oxygen pipeline, low pressure oxygen pipeline and a gasoline pipeline, and a gasoline and oxygen mixing chamber is arranged in the middle of the gun head. The lower part of the gun head is provided with a cutting and welding mouth outer sleeve, and a jetting annular hole, multi-hole gasification sleeve and a gas storage chamber are arranged in the cutting and welding mouth outer sleeve. Mixed gas which is sprayed out from a groove and oxygen sprayed out from the high pressure oxygen through tube are together combusted at the gun head to be used for cutting and welding. The utility model can cut steel plates with 300 millimeters thickness, and the welded seam is smooth.

Description

Oxygen spray formula fuel evaporation cutting and welding torch

The utility model relates to a kind of gasoline cutting and welding torch, particularly a kind of oxygen spray formula fuel evaporation cutting and welding torch.

Traditional cutting and welding torch is to use acetylene and oxygen to make thermal source, because acetylene is taken place by calcium carbide, the carbide slag environmental pollution is very big, be eliminated, though the cutting and welding torch of the employing gasoline replace ethine that occurs at present, be actually with gasoline and also contain the liquid that 40% left and right sides boiling point is higher than gasoline but cut weldering, therefore gasoline on the market with cutting and welding torch owing to unreasonable structure be actually oil droplet mix with oxygen cut weldering, the oil sources of dying is not fully utilized.Though can make raffinate gasification but energy resource consumption is greatly its disadvantage with electric heating.

The purpose of this utility model is to provide a kind of oxygen spray formula fuel evaporation cutting and welding torch, and its advantage is to make gasoline electrical heating and raffinate can fully be vaporized in addition, secondly is simple and reasonable.

Embodiment of the present utility model is as follows, and it is made up of the small of the stock, the body of a gun and rifle head three parts, and the left side of the described body of a gun links to each other with the rifle head, and the right links to each other with the small of the stock.Oil connection is arranged on the small of the stock, oxygen connection, the fuel feeding control valve, handle, Low Pressure Oxygen control valve and hyperbaric oxygen control valve, all the cutting-welding machine with present is the same, is prior art; The top of the described body of a gun be hyperbaric oxygen tracheae, centre be the Low Pressure Oxygen tracheae and below be oil pipe; Rifle head body is arranged at described rifle head top, there is high pressure oxygen straight channel at the center of rifle head body, the hyperbaric oxygen feed channel is arranged in the upper right quarter, low oxygen pipeline and gasoline pipeline, gasoline oxygen mix chamber is arranged in the rifle centriciput, hold-down nut is arranged outward, the bottom of rifle head is to cut weldering to chew overcoat, be connected with rifle head body by seal, sparge ring is arranged in the seal; The porous type gasifying sleeve is positioned at and cuts internal sleeve that weldering chews overcoat in the outside of rifle head body mesohigh oxygen straight channel bottom, forms gas dome, and the outside of hyperbaric oxygen straight channel foot is the mixed gas outlet road that has a plurality of grooves.

The utility model has the advantages that gasoline can be gasified totally, can save the energy greatly, simple in structure and can cut the steel plate of thickness up to 300m/m, smooth welding joint.

Following preference is described in detail the utility model in conjunction with the accompanying drawings.

Fig. 1 is the utility model oxygen spray formula fuel evaporation cutting and welding torch sketch.

Fig. 2 is the amplification internal structure sketch of rifle head among Fig. 1.

As shown in Figure 1, the oil connection 1 among the small of the stock A, oxygen connection 2, fuel feeding control valve 3, handle 4, Low Pressure Oxygen control valve 5 and hyperbaric oxygen control valve 6 are all the same with existing cutting and welding torch all to be prior art.Oxygen enters behind the handle 4 again by entering Low Pressure Oxygen tracheae 8 and the hyperbaric oxygen tracheae 7 among the body of a gun B behind Low Pressure Oxygen control valve 5 and the hyperbaric oxygen control valve 6 respectively by oxygen connection 2, gasoline enters oil pipe 9 after then crossing oil connection 1 and fuel feeding control valve 3, respectively enter rifle head C then respectively, see also Fig. 2, hyperbaric oxygen feed channel 12 in entering rifle head C in the rifle head body 10, low oxygen pipeline 13 and gasoline pipeline 14; Hyperbaric oxygen feed channel 12 communicates with high pressure oxygen straight channel 11, low oxygen pipeline 13 then communicates with gasoline pipeline 14, and in gasoline oxygen mix chamber 15, mix mutually, promptly mix for the first time, after the mixing, enter and cut the space that 18 of overcoat 21 and porous type gasifying sleeves are chewed in weldering by spraying annular distance 17 again, because making to cut to weld, cutting and welding torch head C flame in the room when cutting weldering chews overcoat 21 heatings, cause and cut weldering and chew gasoline in the space of 18 of overcoat 21 and porous gasifying sleeves and drip and gasify and formation oxygen and gasoline gas mixture, enter gas dome 19 by porous gasifying sleeve 18, pass through a plurality of groove 20 in outside of the foot of hyperbaric oxygen straight pipe 10 again, chew the exit ejection of the foot of overcoat 21 from cutting weldering, high pressure oxygen then in the high pressure oxygen straight channel 10 ejections and low oxygen and fuel evaporation body mixture mix last ignition mutually and burn into the row cutting or weld.Nut 16 be used for fixing among the rifle head C gasoline oxygen mix chamber 15 with cut weldering and chew overcoat 21.Seal 22 is to make to cut top and the joint, bottom, gasoline oxygen mix chamber that weldering chews overcoat 21 and seal.
