Abstract
The utility model discloses a portable gas welding torch assembly with a single tube, wherein a nozzle is arranged in a single hole base in interference fit. A ventilating hole is arranged on the side wall of the single hole base corresponding to the opening of the nozzle. A gas inlet is arranged at one end of the single hole base while an initial eruption tube with a Venturi is connected to the other end thereof in interference fit. The end of the initial eruption tube is connected with a short shaft sleeve in threaded connection with a long shaft sleeve. The long shaft sleeve is connected with a secondary eruption tube with a fire outlet processed by constriction. The secondary eruption tube is provided with a flow stabilizing element corresponding to the long shaft sleeve. With the utility model, the gas sprayed out from the nozzle is contacted with air adequately at the ventilating hole to break through conventional simultaneous work of two gas bottles, thereby improving the safety of welding operation and the utility model has a compact structure and is convenient to carry. The conventional eruption tube is divided into the initial and secondary eruption tubes connected through the long and short shaft sleeves so as to disassemble, clean and change the initial eruption tube independently, thereby saving the construction material and heat.

Be provided with Venturi tube in the said elementary spit tube, said Venturi tube end is connected in said single hole base through elementary spit tube interference fit.
The crater of said secondary spit tube is provided with the larynx that contracts.
Be provided with the current stabilization member corresponding to said major axis cover position in the said secondary spit tube, said current stabilization member comprises that the endoporus of said mount pad is provided with the current stabilization blade in order to be connected in the mount pad of said secondary spit tube.
The beneficial effect of the utility model is:
(1) compact conformation, advantages of small volume, processing ease, easy to use, be easy to carry, be suitable for the welding of field work, work high above the ground and miniature parts, be particularly suited for the long-pending less copper pipe of welded section.
(2) be connected with fuel gas bottle or adjuster with the single hole base, combustion gas fully contacts with air at passage from nozzle ejection back, need not to dispose separately oxygen cylinder, and energy savings has broken through traditional two gas cylinders operation simultaneously, the security that has improved weld job;
(3) traditional spit tube is split elementary spit tube and the secondary spit tube that becomes through long and short axle sleeve connection; Like this; The secondary spit tube of being convenient to be prone to pollution and damaging is dismantled separately, is cleaned and changes, and need not change elementary spit tube, saves construction material effectively; Simultaneously, secondary spit tube temperature is low during welding gun work, but hand touches saving heat energy;
(4) Venturi tube that is provided with in the elementary spit tube plays the booster and speed-increasing effect to fuel gas flow;
(5) the current stabilization structure that is provided with in the secondary spit tube makes at the uniform velocity flame stabilization of air-flow, significantly increases speed and the intensity that fires;
(6) the larynx design of contracting of secondary spit tube crater can be played windbreak function effectively, and it is stable further to guarantee to fire.

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 single tube gas welding torch assembly, mainly is made up of single hole base 1, nozzle 2, elementary spit tube 4, secondary spit tube 8, major axis cover 6 and short sleeve 5.
As shown in Figure 2, an end of single hole base 1 is a fuel gas inlet, 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, and is provided with helicitic texture usually.The other end of single hole base 1 is used for and elementary spit tube 4 and Venturi tube 3 interference fit.Single hole base 1 inside is equipped with nozzle 2, and the structure of nozzle 2 is as shown in Figure 3, and single hole base 1 sidewall offers two passages 11 corresponding to the spout place of nozzle, the fuel gas by nozzle 2 ejections is communicated, so that fully contact with air with atmospheric environment.
The other end of single hole base 1 is connected with elementary spit tube 4, elementary spit tube 4 one ends and single hole base 1 interference fit, and the other end is provided with the flange enlarging, is connected on the short sleeve 5 through the flange enlarging.To shown in Figure 5, short sleeve 5 is provided with internal thread 51 like Fig. 4, is used for being connected with external screw thread 61 matching threads of major axis cover 6.One end of secondary spit tube 8 also is provided with and is used for the flange enlarging that is connected with major axis cover 6, and the other end is a crater, through the larynx processing of contracting, plays windbreak function effectively.
