Abstract
The utility model relates to an injection type industrial gas welding-cutting torch, which is characterized in that a nozzle and an injection pipe are disposed in a mixing chamber of the injection type industrial gas welding-cutting torch, the bore diameter of the nozzle ranges from phi 0.7mm to phi 1.5mm, the bore diameter of a straight-hole section of the injection pipe ranges from phi 1.5mm to phi 3.5mm, and the distance from the end face of the nozzle to an inlet of the injection pipe ranges from 2mm to 3mm. The injection type industrial gas welding-cutting torch is applicable to flame cutting of ferrous metal and welding of nonferrous metal, the cost can be effectively reduced by more than 70%, and the injection type industrial gas welding-cutting torch has evident economic benefit.
Description
Technical field
The utility model relates to a kind of to the flame cutting of ferrous metal and the cutting torch that non-ferrous metal is welded, particularly a kind of jet absorption type industrial combustion gas welding torch.
Background technology
At present, domestic in steel and iron industry to the cutting of the flame of ferrous metal with to the non-ferrous metal welding, what tradition adopted is the oxy-acetylene flame cutting, this oxy-acetylene flame cutting exists: problems such as cost height, poor stability, contaminated environment.
Summary of the invention
The utility model has overcome the defective of above-mentioned existence; Purpose provide industrial combustion gas such as a kind of employing petroleum gas resource natural gas, propane, propylene be raw material replace ethine gas to the ferrous metal fly-cutting, realize energy-conservation, safety, environmental protection, the jet absorption type industrial combustion gas welding torch that reduces cost.
The utility model jet absorption type industrial combustion gas welding torch content Description:
The utility model jet absorption type industrial combustion gas welding torch; It is characterized in that: in the mixing chamber of jet absorption type industrial combustion gas welding torch, nozzle and injecting tube are set; The aperture of nozzle is φ 0.7 mm～1.5mm; The aperture of the straight hole section of injecting tube is φ 1.5 mm～3.5mm, and the distance of the end face of nozzle to injecting tube import is 2 mm～3 mm.
The utility model jet absorption type industrial combustion gas welding torch is applied to the flame cutting of ferrous metal and to the non-ferrous metal welding, can effectively reduces cost more than 70%, has remarkable economic efficiency.
Description of drawings
［ 0004 ］ Fig. 1 is a jet absorption type industrial combustion gas welding torch structural representation
Among the figure: the 1st, nozzle, the 2nd, injecting tube.
The specific embodiment
［ 0005 ］ the utility model jet absorption type industrial combustion gas welding torch is achieved in that to do below in conjunction with accompanying drawing and specifies.See Fig. 1; Nozzle 1 and injecting tube 2 are set in the mixing chamber of jet absorption type industrial combustion gas welding torch; The aperture of nozzle 1 is φ 0.7 mm～1.5mm, and the aperture of the straight hole section of injecting tube 2 is φ 1.5 mm～3.5mm, and the distance of the end face of nozzle 1 to injecting tube 2 imports is 2 mm～3 mm.
The utility model is different according to the mixing ratio of oxygen-industrial combustion gas, confirms the relative dimensions of mixing chamber, makes jet absorption type industrial combustion gas welding torch can reach stable and effectively work.
During use, when preheated oxygen passes through nozzle 1 flow at high speed, in the mixer generation negative pressure of injecting tube 2; Combustion gas is sucked mixing chamber and oxygen mix; Be delivered to the welding mouth through the expansion segment supercharging, burning forms welding and cutting flame, realizes non-ferrous metal welding and ferrous metal cutting.
