Description
Technical field
The utility model relates to a kind of cutting torch.
Background technology
Cutting torch is generally used for gas cutting field, and gas flame can be assembled the position being attached to required processing by cutting torch, overcomes flame dispersion phenomenon, both can improve cutting effect, can ensure cut quality again, save oxygen simultaneously.Cutting torch is when cutting, and usually utilize two-way pipeline to pass into mist and cutting oxygen respectively, during mist, acetylene and oxygen mix form.The cutting torch of said structure in use, due to operating personnel the flame of ejection is too near to material to be cut time, may Quench be there is, and extinguish the moment flame reverse back that may cause and enter in mixture pipe.Thus cause mixture pipe to melt because of tempering, serious that steel cylinder blast etc. may occur is unexpected, constitutes a threat to the safety of operator.
Utility model content
The utility model, in order to solve the problem of prior art, provides a kind of structure simple, can effectively prevent tempering from blowing the Novel cutting nozzle of mixture pipe.
Concrete technical scheme is as follows: a kind of Novel cutting nozzle, comprise head, pin portion, sleeve and branching block, described branching block is connected with head, described pin portion is located in sleeve, described sleeve is arranged in branching block, described cutting torch also comprises flow chock, in the middle part of flow chock, there is gas passage, the first end of flow chock has chamfering hypotenuse, there is in described head the first hole, first hole top has end difference, the first end of described flow chock relies on end difference, cutting oxygen body pipeline is provided with in described head, oxygen gas pipeline and acetylene gas pipeline, be communicated with by narrow passage between oxygen gas pipeline and acetylene gas pipeline.
It is below attached technical scheme of the present utility model.
Preferably, the tapered long tubular of described flow chock.
Preferably, described narrow passage is horizontally installed between oxygen gas pipeline and acetylene gas pipeline.
Preferably, described cutting torch also comprises securing member, and securing member and branching block 4 connect.
Preferably, described cutting torch also comprises the second hole, and the second hole is provided with internal thread, and branching block and the second hole are threaded connection.
Technique effect of the present utility model: Novel cutting nozzle of the present utility model is by arranging flow chock to control oxygen flow and to intercept tempering, described oxygen gas pipeline is connected by narrow passage with acetylene gas pipeline, make the mist produced in advance for lighting can form admixture at head, thus the gas piping that can prevent tempering from being connected by head outward damage.
Accompanying drawing explanation
Fig. 1 is the exploded view of the Novel cutting nozzle of the utility model embodiment.
Fig. 2 is the sectional view of the Novel cutting nozzle of the utility model embodiment.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described further.
As depicted in figs. 1 and 2, the Novel cutting nozzle of the present embodiment, comprise head 1, pin portion 2, sleeve 3 and branching block 4, described head 1 one end has the first hole 11, in first hole 11, there is threaded portion 111, head 1 comprises column 15, is provided with three independently gas pipings in head 1, and forms protuberance 12 in middle part, described three independently gas piping be respectively cutting oxygen body pipeline 5, oxygen gas pipeline 6 and acetylene gas pipeline 7, described first hole 11 is arranged in described protuberance 12, and the first hole 11 top has end difference 122.Described cutting torch also comprises flow chock 9, its tapered long tubular, it is arranged on described threaded portion 111 place, flow chock 9 first end 91 has chamfering hypotenuse, the middle end of chamfering hypotenuse has through gas passage 51, and the end that flow chock 9 has chamfering hypotenuse and gas passage 51 relies on described end difference 122.Second hole 14 of described head 1 is provided with internal thread 13, and the external screw thread 41 on described branching block 4 is connected by internal thread 13 and head 1.Be provided with narrow pipeline 7 in described cutting torch, narrow pipeline 7 connects oxygen gas pipeline 6 and acetylene gas pipeline 7, and narrow pipeline 7 is horizontally installed between oxygen gas pipeline 6 and acetylene gas pipeline 7.Described cutting torch also comprises securing member 50, and securing member 50 and branching block 4 connect, and pin portion 2 and sleeve 3 are fixed in branching block 4.
The Novel cutting nozzle of the present embodiment is when enabling, and acetylene gas flows into cutting torch by acetylene gas pipeline 7, forms mist via narrow pipeline 8 with the oxygen in oxygen gas pipeline 6 at the first hole 11 place.The described mist that can be used for lighting, by the multiple tap holes on the end face of branching block 4, is sprayed by the port 21 in pin portion 2 through the inside of sleeve 3.After lighting, cutting oxygen, is directly sprayed (as shown by the arrows in Figure 2) by the port 21 in pin portion 2 by the cutting gas passage 421 of the afterbody 42 of branching block 4 by cutting oxygen body pipeline 5.The flame can strengthening previously putting the mist used sprays intensity, thus controls the degree of depth of cutting.When there is tempering, when flame enters in the second hole 14 of head 1, because being provided with horizontal narrow pipeline 8 between acetylene gas pipeline 7 and oxygen gas pipeline 6, also be provided with flow chock 9 to intercept simultaneously, described tempering can be isolated, acetylene gas pipeline 7 and oxygen gas pipeline 6 can not be blown, thus ensure the safety of operator.And because gas pressure is high in cutting oxygen body pipeline 5, tempering can be disappeared by the resistance of the gas of high pressure.
The present embodiment Novel cutting nozzle is by arranging flow chock to control oxygen flow and to intercept tempering, described oxygen gas pipeline is connected by narrow passage with acetylene gas pipeline, make the mist produced in advance for lighting can form admixture at head, thus the gas piping that the head that can prevent tempering from producing connects damage outward.It is to be noted; above-mentioned preferred embodiment is only and technical conceive of the present utility model and feature is described; its object is to person skilled in the art can be understood content of the present utility model and implement according to this, protection domain of the present utility model can not be limited with this.All equivalences done according to the utility model Spirit Essence change or modify, and all should be encompassed within protection domain of the present utility model.
