The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is done further to describe in detail:
As shown in Figure 1, present embodiment has disclosed a kind of portable three pipe gas welding torch assemblies, mainly is made up of three hole bases 1, nozzle 2, elementary spit tube 4, secondary spit tube 8, major axis cover 6 and short sleeve 5.
In conjunction with Fig. 2 and shown in Figure 3, an end of three hole bases 1 is provided with a fuel gas inlet 13, and fuel gas inlet 13 is connected with internal thread swivel joint 10, and internal thread swivel joint 10 is used for being connected with fuel gas bottle or the adjuster that the is connected in fuel gas bottle bar of giving vent to anger; The other end is provided with three installing holes 12, is used to install nozzle 2, and with elementary spit tube 4 and Venturi tube 3 interference fit.Particularly; Each installing hole 12 inside is separately installed with a nozzle 2; The structure of nozzle 2 is as shown in Figure 3; Three hole bases, 1 sidewall is provided with three vent grooves 11 corresponding to the nozzle exit area of three nozzles 2, the fuel gas by nozzle 2 ejections is communicated, so that fully contact with air with atmospheric environment.
