Description

Self-heating gasoline metal welding cutter

The utility model relates to a kind of self-heating gasoline metal welding cutter.

Traditional metal cutter is to make fuel with acetylene, and with comburant oxygen, the thermal-flame of generation carries out gas welding or cutting to metalwork, and acetylene is to add the gaseous fuel that water produces by calcium carbide.Therefore its cutting torch is relatively simple for structure with cutting torch, but it is bigger to produce the generator volume of acetylene, inconvenience when transportation is moved, and the deposit of acetylene easily leaks, smell and danger are also deposited, safety inadequately, with after also can produce carbide slag and contaminated environment.Known solution is normally carried out around the improvement of acetylene generator, even substitutes acetylene generator with canned acetylene cylinder, thereby has increased cost, does not also fundamentally solve the problem that exists.

The purpose of this utility model provides and a kind ofly substitutes acetylene with gasoline, and can gasify on cutting torch, and with the self-heating gasoline metal welding cutter of comburant oxygen, it is inconvenient that it can solve carrying preferably, uses problems such as dangerous and contaminated environment.

Task of the present utility model is finished in the following way:

A complete set of utensil still keeps oxygen cylinder, external hose, handle type cutting torch, but the cutting torch that inner sleeve and nozzle core are set in the housing of fixing with the nut coupling sleeve is installed on the nut sleeve of cutting torch, and the tank body at the gasoline oil tank is provided with pressue device, goes into oily safeties and fuel delivery device in addition.

Nozzle core is made of cylindrical nozzle and sleeve sections, centrum cannelure section and ladder disk segments, and the center has bore diminishing into and out of pore.

The ladder air admission hole outer of the ladder disc centre of nozzle core is evenly equipped with the oil-feed axial aperture, and the taper venthole outer at cylindrical nozzle center is evenly equipped with the oil spout axial slot.

The pressue device of oil tank is made up of Pressure gauge, inflator and the check valve that links thereof.

The fuel delivery device of oil tank by connect under the oil pipe filter, on connect choke valve and oil-out is formed.

The oily safeties of going into of oil tank are made up of oiler and the pressure limiting valve that links thereof, seal cover.

The utility model is because only need to change the cutting torch structure, makes it be suitable for gasoline heat up atomizing and fully burning, so welding temperature height, speed are fast; Simultaneously owing to substitute acetylene generator with oil tank, so the unitary construction volume is little, in light weight, fuel price is than low and do not produce waste residue and help environmental protection, also operation under water.

The concrete structure of utility model is provided by following embodiment and accompanying drawing thereof.

Fig. 1 cuts open schematic diagram according to the office of the self-heating gasoline metal welding cutter handle type cutting torch that the utility model proposes.

Fig. 2 is that the A of Fig. 1 cuts open enlarged drawing to office.

Fig. 3 is that schematic diagram is looked on the right side of Fig. 1.

Fig. 4 is that schematic diagram is looked on the left side of nozzle core ladder disk shown in Figure 1.

Fig. 5 is according to self-heating gasoline metal welding cutter tank structure or the organigram that the utility model proposes.

Below in conjunction with details and the working condition of accompanying drawing detailed description according to the concrete device that the utility model proposes.

As shown in Figure 1, be with inner sleeve [1], nozzle core [3] in the housing of frustum shower nozzle [2], constitute cutting torch; Cutting torch is assemblied in the nut sleeve [7] of cutting torch with nut coupling sleeve [8]; Gasoline is by the oily cannelure [4] of the direction shown in the solid arrow in petroleum pipeline [9] enters nut sleeve [7], and air inlet axial aperture [3-4], cone cannelure [3-3], the A district from the ladder disk [3-5] of nozzle core [3] arrives shower nozzle again; Oxygen enters gas ring shape groove [5] in the nut sleeve [7] by direction shown in the dotted arrow through oxygen therapy tracheae [6], arrive shower nozzle from the oil-feed axial aperture [3-6] of ladder disk [3-5], the taper hole of giving vent to anger [3-7] of cylindrical nozzle [3-1] again, the gasoline that mixes with extruding heating atomization or liquid gas converges, and lights shower nozzle and gets final product work.Fig. 2 is that amplify in the A district of Fig. 1, be gasoline between housing [2] inwall and sleeve [3-2], between sleeve [3-2] and inner sleeve [1], form S shape annulus [10] between inner sleeve [1] and cylindrical nozzle [3-1], gasoline causes certain temperature rise in flowing in this slit, major part obtains gasification.Cylindrical nozzle [3-1] shown in Figure 3, that housing [2] and inner sleeve [1] are wrapped up, the uniform oil spout axial slot [3-8] in taper venthole [3-7] outer of visible oxygen on its anchor ring, will dripping equably through the gasoline of gasification or not gasification, shunting rushes at spout.The ladder disk [3-5] of Fig. 4 nozzle core [3], its center are ladder air admission hole [3-6], and the outer is oil-feed axial aperture [3-4] distribution signal.

As shown in Figure 5, the tank body of oil tank [11] is respectively equipped with the pressue device of being made up of Pressure gauge [12-3], inflator [12-2] and the check valve [12-1] that links thereof [12], go into oily safeties [13] by what seal cover [13-1], oiler [13-2] and the pressure limiting valve [13-3] that links thereof were formed, by connecting filter [14-4] under the oil pipe [14-3], on connect the fuel delivery device [14] that choke valve [14-2] and oil-out [14-1] thereof form and constitute.Open seal cover [13-1] and can in tank body [11], add gasoline; Inflator [12-2] moves up and down check valve [12-1] is opened, in tank body [11], squeeze into compressed air, make gasoline level have pressure P 0 and pass through Pressure gauge [12-3] to show the pressure size, during its hypertonia, then pressure limiting valve [13-3] can be opened decompression automatically, on the contrary auto-closing then.Because the interior gasoline pressurized of tank body [11], gasoline filters the back through filter [14-4] and enters choke valve [14-2] from oil pipe [14-3] rising, flows out to oil-out [14-1] again, and oil-out [14-1] outlet pressure is P1.Choke valve [14-2] plays switch and regulates oil mass.Oil-out [14-1] external hose is delivered to the petroleum pipeline [9] of the nut sleeve [7] of cutting torch by flexible pipe with repressuring gasoline, and the oxygen therapy tracheae [6] of nut sleeve [7] also is connected with flexible pipe with oxygen cylinder.
