Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described further.
As shown in Figure 1 to Figure 3, the cutting torch of the present embodiment comprises main body 1, cutting torch 2, and cutting tracheae 3, grip pipe 7 and mixture pipe 4, described cutting torch 2 is arranged on main body 1 end.Described gripping pipe 7 two ends are respectively equipped with the first distributor 5 and the second distributor 6, and described gripping pipe 7 has inner space 8, is provided with conduit 12 in described inner space 8, and the first distributor 5 is connected by gripping pipe 7 with the second distributor 6.Described first distributor 5 comprises cutting oxygen passage 51, preheat oxygen passage 52 and fuel gas passageway 53, cutting oxygen passage 51 is provided with the first control valve 9, preheat oxygen passage 52 is provided with the second control valve 10.Described second control valve 10 has spicule 101 and injector 102, thus has flow regulating function, and by the fuel gas from fuel gas passageway 53 can be attracted from injector 102 jet preheat oxygen.Described second distributor 6 comprises oxygen path 61 and fuel gas path 62, and fuel gas path 62 is provided with the 3rd control valve 11.Described cutting torch 2 comprises the pilot hole 27 of burner 100, cutting oxygen pipe road 28 and gaseous mixture pipeline 29, and cutting oxygen pipe road 28 connects cutting tracheae 3, and gaseous mixture pipeline 29 connects mixture pipe 4.Described mixture pipe 4 is provided with the reception room 20 with certain length near cutting torch 2 side, the diameter of reception room 20 is larger than the internal diameter of the gas piping 41 of mixture pipe 4 inside.Be provided with fireproof tempering device 21 in described reception room 20, fireproof tempering device 21 is made up of helical metal plate.Described mixture pipe 4 is also provided with screwed pipe 42, mixing tube 43 and tube connector 44.Described screwed pipe 42 is for being connected with cutting torch 2.
Described mixing tube 43 is for promoting preheat oxygen and fuel gas mixing.Described tube connector 44 is arranged between screwed pipe 42 and mixing tube 43, described reception room 20 arrange tube connector 44 by screwed pipe 42 side.The diameter of described reception room 20 is arranged according to the internal diameter of gas piping 41, and in the present embodiment, the internal diameter of gas piping 41 is 4mm, and the diameter of reception room 20 is 4.5mm to 5.0mm, and the length of reception room 20 is 50mm.Owing to being provided with reception room 20 in mixture pipe 4, therefore mixture pipe 4 is thinner at other positions of position wall ratio of reception room 20, thus contributes to heat radiation.Described fireproof tempering device 21 is helical form, thus the path formed is longer than the length of reception room 20, and gas when therefore there is tempering cools by fireproof tempering device 21.
When the cutting torch generation tempering of the present embodiment, the gas of HTHP, from burner 100 along gaseous mixture pipeline 29 adverse current, arrives reception room 20 from mixture pipe 4 and collides fireproof tempering device 21; Gas pressure through collision rift reduces, and flow velocity reduces; Meanwhile, gas is cooled by fireproof tempering device 21 and temperature is reduced, thus ensures that cutting torch is not damaged, guarantees job safety.
