Abstract
The utility model discloses a fire arresting mixing pipe for a cutting torch, comprising a mixing pipe body (1) and a fire arresting device, wherein the front end of the mixing pipe body is communicated with a cutting nozzle of the cutting torch; and the fire arresting device is arranged on the front part of the chamber of the mixing pipe body (1). A spiral fire arrester which extends along the length direction is arranged on the front part of the chamber of the fire arresting mixing pipe for the cutting torch, so that the returned fire can be effectively prevented from entering the mixing pipe of the cutting torch, the pipe explosion accident is avoided, and even air sources are prevented from tempering, burning and exploding. In the fire arresting mixing pipe, not only resources are saved, but also the using safety of the cutting torch is improved.
Description
Technical field
The utility model relates to the welding technical field, particularly a kind of back-fire relief mixing tube that is used for cutting torch.
Background technology
Adopt the gas flame cutting because it has efficient height, low cost and other advantages, and be widely used in industrial cutting steel plate etc.Cutting torch is the main tool of gas flame cut workpiece.Cutting torch commonly used mainly is made up of cutting torch portion, cutting oxygen pipe, mixture pipe, cutting oxygen valve, oxygen valve, oxygen intake pipe, combustion gas (acetylene gas, natural gas, propane flammable gas etc.) air inlet pipe, handle and main body.When using cutting torch cutting steel, owing to manipulate lack of standardization or the flame enrichment phenomenon can take place the environment for use inclement condition, when tempering entered mixing tube, serious meeting generation bombing related to the safety of operator and periphery.Because the mixing tube of the cutting torch of prior art is generally a straight pipe, fire retardant device is not set in the mixing tube, during work, in case generation tempering phenomenon, then the operator must close the gas source switch of cutting torch tail end rapidly, cut off air feed, just can avoid the generation of source of the gas tempering burning even the accident of blasting.
Summary of the invention
Technical problem to be solved in the utility model is: a kind of generation that can effectively avoid tempering phenomenon is provided, has improved the back-fire relief mixing tube that is used for cutting torch of the security of cutting torch use.
The technical scheme in the invention for solving the above technical problem is: a kind of back-fire relief mixing tube that is used for cutting torch, comprise the mixing tube body that front end is connected with the cutting torch of cutting torch, it also comprises fire retardant device, and described fire retardant device is located at the front portion of described mixing tube chamber body.
Described fire retardant device is that extend along its length, spiral spark arrester.
Interference fits between described spark arrester and the described mixing tube body.
Compared with prior art, advantage of the present utility model is: this front portion of inner chamber that is used for the back-fire relief mixing tube of cutting torch is provided with that extend along its length, spiral spark arrester, like this, can effectively stop tempering to enter in the mixing tube of cutting torch, the bombing accident be can not produce, the generation of source of the gas tempering burning even the accident of blasting avoided.This back-fire relief mixing tube has not only been realized the saving of resource, and has improved the security that cutting torch uses.
Description of drawings
Accompanying drawing is the structural representation that the utility model is used for the back-fire relief mixing tube of cutting torch.
In the accompanying drawing: 1 mixing tube body, 2 spark arresters.
The specific embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is further described.
As shown in drawings, a kind of back-fire relief mixing tube body that is used for cutting torch comprises the mixing tube 1 that front end is connected with the cutting torch of cutting torch, and it also comprises fire retardant device, and described fire retardant device is located at the front portion of described mixing tube body 1 inner chamber.
In this specific embodiment, described fire retardant device is that extend along its length, spiral spark arrester 2.
In this specific embodiment, interference fits between described spark arrester 2 and the described mixing tube body 1.
Below only be described, but can not be interpreted as it is restriction claim with regard to most preferred embodiment of the present utility model.The utility model not only is confined to above embodiment, and its concrete structure allows variation.All various variations of being done in the protection domain of the utility model independent claims are all in the utility model protection domain.
Claims (3)
1. a back-fire relief mixing tube that is used for cutting torch comprises the mixing tube body (1) that front end is connected with the cutting torch of cutting torch, and it is characterized in that: it also comprises fire retardant device, and described fire retardant device is located at the front portion of described mixing tube body (1) inner chamber.
2. the back-fire relief mixing tube that is used for cutting torch according to claim 1 is characterized in that: described fire retardant device for extend along its length, spiral spark arrester (2).
3. the back-fire relief mixing tube that is used for cutting torch according to claim 2 is characterized in that: interference fits between described spark arrester (2) and the described mixing tube body (1).
