Description
Technical field
Metal cutting tool technical field is the utility model is related to, particularly a kind of injector cutting torch of anti-tempering.
Background technology
Gas cutting cuts indispensable technique as steel, is used till today always since the fifties, common burner
With two kinds of injector cutting torch and isobaric cutting torch；
Isobaric cutting torch innately has the advantages of safe, but mix oxygen and combustion by the way of pure gas supply
Gas by the way of directly mixing, two kinds of gas it is larger for draught head, during mixing, be not easy to adjust to suitable proportioning, at the same time
The processing request of isobaric cutting torch and cutting torch is high, and use cost is high；
Injector cutting torch designs greatly precisely in order to solving two kinds of fluid mixing difficulty there are pressure difference, but passes
Injector cutting torch of uniting uses the structure of long distance transmission after mixture of oxygen and combustion gas mixing, causes easy tempering, security is not high
The shortcomings that.
Utility model content
The purpose of this utility model is to provide a kind of anti-tempering, easily mixing, the low injector cutting torch of consumables cost.
The purpose of this utility model is achieved through the following channels：A kind of injector cutting torch of anti-tempering, it includes cutting
Torch main body, cutting torch main body be equipped with Gas Pipe, cutting oxygen pipe, the Gas Pipe, cutting oxygen pipe tail end respectively with pipe joint
Connection, front end are connected with cutting torch, further include mixing oxygen pipe and injecting tube, mix oxygen pipe and injecting tube is all built in Gas Pipe,
Injecting tube front end is connected with cutting head joint, and tail end is connected with mixing the front end of oxygen pipe, is closed oxygen pipe tail end and is connected with spray nozzle of the gas supply；Institute
The injecting tube stated is internally provided with the passage i.e. medium pore canal of mixing oxygen, and the tube wall of injecting tube is provided with the horizontal stroke of several combustion gas entrance
Hole.
As the further optimization of this programme, the injecting tube is with mixing oxygen pipe, injecting tube and cutting head joint, injecting tube
All it is connected between Gas Pipe by the way of soldering.
As the further optimization of this programme, using the side of O-ring sealing between the mixing oxygen pipe and spray nozzle of the gas supply
Formula connects.
As the further optimization of this programme, use and be threadedly coupled between the spray nozzle of the gas supply and main body.
A kind of injector cutting torch of anti-tempering of the utility model, is supplied using three kinds of pipelines, has abandoned traditional jet absorption type and cut
The mode of torch gaseous mixture supply over long distances, the transmission of pure gases is compared with gaseous mixture by the way of pure gas isolation transmission
Transmission, security are greatly improved.
Brief description of the drawings
The utility model is described in further detail below in conjunction with the accompanying drawings：
Fig. 1 is the utility model overall structure diagram；
Fig. 2 is the B of Fig. 1 to partial enlarged view；
Fig. 3 is the C of Fig. 1 to partial enlarged view；
Fig. 4 is 5 structure diagram of injecting tube；
In figure, cutting head joint 1, Gas Pipe 2, cutting oxygen pipe 3, mixing oxygen pipe 4, injecting tube 5, cross-drilled hole 6, medium pore canal 7, confession
Gas jets 8, cutting torch main body 9.
Embodiment
As Figure 1-Figure 4, a kind of injector cutting torch of anti-tempering of the utility model, it includes cutting torch main body 9, cutting torch master
Body 9 is equipped with Gas Pipe 2, cutting oxygen pipe 3, and the Gas Pipe 2,3 tail end of cutting oxygen pipe are connected with pipe joint respectively, front end
It is connected with cutting head joint 1, further includes mixing oxygen pipe 4 and injecting tube 5, mixing oxygen pipe 4 and injecting tube 5 are all built in Gas Pipe 2,
5 front end of injecting tube is connected with cutting head joint 1, and injecting tube 5 is placed in 9 front end of cutting torch main body, the quantity of gaseous mixture is controlled in minimum
In the range of, in view of the tempering probability of gaseous mixture is higher, the quantity of gaseous mixture is reduced, tempering probability can be effectively reduced, drop at the same time
The low explosion energy produced by tempering, so as to greatly improve the security of gas cutting.Tail end connects with mixing the front end of oxygen pipe 4
Connect, close 4 tail end of oxygen pipe and be connected with spray nozzle of the gas supply 8；Mixing oxygen pipe 4 is built in Gas Pipe 2, mixing oxygen pipe 4 and Gas Pipe 2 it
Between form a circular passage, by the passage, the cross-drilled hole 6 for having injecting tube 5 enters injecting tube 5 and is mixed into mixing oxygen for combustion gas
Flammable gaseous mixture.
The injecting tube 5 is internally provided with the passage i.e. medium pore canal 7 of mixing oxygen, and the tube wall of injecting tube 5 is provided with several
The cross-drilled hole 6 that combustion gas enters.
The injecting tube 5 is all adopted with mixing between oxygen pipe 4, injecting tube 5 and cutting head joint 1, injecting tube 5 and Gas Pipe 2
Connected with the mode of soldering.
Connected between the mixing oxygen pipe 4 and spray nozzle of the gas supply 8 by the way of O-ring sealing.
Use and be threadedly coupled between the spray nozzle of the gas supply 8 and main body 9.
Operation principle:Injecting tube is a kind of Venturi tube, meets Venturi effect, and centre gangway is passed through gases at high pressure, in side
To cross-drilled hole in can produce negative pressure, application of the effect in cutting torch is:The larger oxygen of pressure passes sequentially through nozzle, mixing oxygen
Pipe, then enters injecting tube from the centre gangway of injecting tube, while the combustion gas of low pressure passes through Gas Pipe and the interlayer of mixing oxygen pipe
At the cross-drilled hole for reaching injecting tube, negative pressure that Venturi effect produces increases the pressure that big combustion gas enters injecting tube, two kinds of pressure differences compared with
Big gas is smoothly mixed into the gaseous mixture that can be burnt in injecting tube and is sent into cutting head joint, and reaches cutting torch and be ignited.
The above, is only specific embodiment of the present utility model, but the scope of protection of the utility model is not limited to
