Abstract
The utility model discloses an anti-tempering welding and cutting torch, and mainly aims to provide a welding and cutting torch which ensures that burnt high-temperature and high-pressure gas can be instantaneously refluxed and is cooled and subjected to fire extinguishing in case of tempering. The anti-tempering welding and cutting torch comprises a front part, a mixing pipe, a jet-suction pipe and an anti-tempering device arranged on the mixing pipe, wherein the two ends of the mixing pipe are welded with the front part and the jet-suction pipe respectively; the anti-tempering device comprises a main body and a joint which are connected to the mixing pipe; the main body and the joint are connected to form a hollow sleeve; a fire extinguishing pipe matched with the sleeve is arranged in the sleeve; a spring seat and a spring connected to the spring seat are arranged in the fire extinguishing pipe; and the other end of the spring is connected with a valve core. According to the anti-tempering welding and cutting torch, the anti-tempering device is arranged at the front end of the mixing pipe, so that the optimal anti-tempering effect is achieved, and the usability and safety performance of the product are improved.
Description
Technical field
The utility model relates to a kind of anti-reversal-flame type welding torch.
Background technology
The structure (as shown in Figure 1) of jet absorption type welding torch employing at present mostly is made up of front portion 1, middle part 2, rear portion 4 and associated component, passes through tracheae soldering and nonreactive back-fire arrangement between portion's body.Sometimes the operator mostly is equipped with independent torch with back- fire arrangement 3,5 at its rear portion air inlet in order to improve safety guarantee when work; Reach the purpose of anti-tempering; Tend to like this occur that the welding torch uses or during user's misoperation generation tempering in varying environment; The high temperature and high pressure gas moment backflow of burning; When air-flow arrival pore place, injecting tube center can not get in time discharging, very easily before and after weld, sharply expand explosion takes place, thereby cause unnecessary economic loss even actual bodily harm to the user.And at this moment the torch of independent installation does not play effective prevention effect with back-fire arrangement, only can prevent that burning gases from continuing to be back in the gas circuit sebific duct.
The utility model content
To the problems referred to above, the utility model provides a kind of anti-reversal-flame type welding torch.
For achieving the above object, the anti-reversal-flame type welding of the utility model torch comprises front portion, mixing tube and injecting tube, and wherein said mixing tube two ends are welded to connect said front portion and said injecting tube respectively, also comprise the anti-back-fire arrangement that is arranged on the said mixing tube.
Further; Said anti-back-fire arrangement comprises main body and the joint that is connected on the said mixing tube; Said main body and joint are interconnected to form the cannulated sleeve structure; Be provided with in the said tube-in-tube structure and the suitable fire-stopping pipe of said sleeve, be provided with spring abutment in the said fire-stopping pipe and be connected the spring on the said spring abutment, the said spring other end is connected with spool.
Preferably, said main body and said joint are all through O type circle and the sealing of said mixing tube.
Further, said main body and said joint are provided with groove, and said O type snare is located in the said groove.
Particularly, be respectively equipped with two grooves on said main body and the said joint.
The anti-reversal-flame type welding of the utility model torch; Join an anti-back-fire arrangement through increasing at the mixing tube front end, when tempering takes place when, the high temperature and high pressure gas moment backflow of burning; When the fire-stopping pipe place that arrives through mixing tube in the anti-back-fire arrangement; Playing flame-out cooling effectively, reducing the effect of pressure, thereby reaching the purpose of the most effective anti-tempering, having improved the serviceability and the security performance of product.
Description of drawings
Fig. 1 is the structural representation of welding torch of the prior art;
Fig. 2 is the structural representation intention of the embodiment of the anti-reversal-flame type welding of the utility model torch;
Fig. 3 is the structural representation of the anti-back-fire arrangement of the anti-reversal-flame type welding of the utility model torch.
The specific embodiment
Below in conjunction with Figure of description the utility model is done further description.
Shown in Fig. 2-3; The anti-reversal-flame type welding of the utility model torch; Comprise front portion 1, mixing tube 3 and injecting tube 4; Wherein said mixing tube 3 two ends are welded to connect said front portion and said injecting tube 4 respectively, also comprise the anti-back-fire arrangement 2 that is arranged on the said mixing tube, and wherein said anterior 1 adopts high brass to forge processes; Mixing tube 3 adopts high-quality H68 brass tube to process; Injecting tube 4 adopts high brass to process.
Further; Said anti-back-fire arrangement 2 comprises the main body 21 and joint 22 that is connected on the said mixing tube 3; Said main body and joint are interconnected to form the cannulated sleeve structure; Be provided with the fire-stopping pipe 23 suitable with said sleeve in the said tube-in-tube structure, be provided with spring abutment 24 in the said fire-stopping pipe and be connected the spring 25 on the said spring abutment, the said spring other end is connected with spool 26; Wherein main body 21, joint 22, spool 26, spring abutment 24, the materials processing of employing high brass form, and fire-stopping pipe 23 adopts stainless steel-based micropore powder alloy material to process.
Preferably, said main body and said joint are all through O type circle and the sealing of said mixing tube.
Further, said main body and said joint are provided with groove 27, and said O type snare is located in the said groove.
Particularly, be respectively equipped with two grooves on said main body and the said joint.
During use; The said anti-reversal-flame type welding torch of the utility model uses in the different operating environment or during user's misoperation generation tempering; The high temperature and high pressure gas moment backflow of burning arrives in the anti-back-fire arrangement 2 through mixing tube 3, when through fire-stopping pipe 23 places; Because the micropore cooling is stopped working and acted on and knock down the flame, spool 26 is closed owing to the gases at high pressure effect simultaneously; After fray-out of flame, gas pressure reduces, and valve is opened, and recovers operate as normal automatically, thereby reaches the purpose of the most effective anti-tempering, has improved the serviceability and the security performance of product, has also guaranteed user's safety.
More than; Be merely the preferred embodiment of the utility model; But the protection domain of the utility model is not limited thereto; Any technical staff who is familiar with the present technique field is in the technical scope that the utility model discloses, and the variation that can expect easily or replacement all should be encompassed within the protection domain of the utility model.Therefore, the protection domain of the utility model should be as the criterion with the protection domain that claim was defined.
