The specific embodiment
Below in conjunction with accompanying drawing the present invention is made detailed explanation.
Like Fig. 1, shown in Figure 2, pressure handle formula provided by the invention is penetrated the suction cutting torch and is comprised main body 1, cutting oxygen pipe 7, mixture pipe 8 and cutting torch 9.
The structure of main body 1 such as Fig. 3-shown in Figure 8; At first referring to Fig. 2 and Fig. 3, the right-hand member of main body 1 is provided with an oxygen intake 11 and acetylene inlet 12, and oxygen intake 11 connects oxygen tube junction 2; Acetylene inlet 12 connects acetylene hose joint 3; Be provided with back-fire arrangement 4 in the acetylene hose joint 3, what back-fire arrangement 4 adopted is prior art, ends fiery sheet, spring and check-valves by stainless steel and forms.Existing common cutting torch; Back-fire arrangement generally all is mounted in the exit of acetylene regulator, is connected with cutting torch through flexible pipe then, and this structure is when more serious tempering takes place; Tend to that injecting tube place (oxygen and acetylene mixing place) at cutting torch is quick-fried to be fallen, cause cutting torch to scrap.The present invention is installed in acetylene 12 places that enter the mouth with back-fire arrangement; Improved tempering greatly and prevented performance, when tempering took place, back-fire arrangement was in the 12 generation effects that enter the mouth of the acetylene of cutting torch; Has only the sub-fraction acetylene gas burning in the cutting torch mixture pipe 8; Will soon protect flexible pipe from horizontal blanking, avoid cutting torch owing to tempering is scrapped.
Referring to Fig. 2 and Fig. 4, the left end of main body 1 is provided with a cutting oxygen outlet 13 and one mixed gas outlet 14, connects cutting oxygen pipe 7 in the cutting oxygen outlet 13 again; Be bolted with injecting tube 5 on the mixed gas outlet 14; The porch of injecting tube 5 is provided with nozzle 6, and nozzle 6 is fixed in the mixed gas outlet 14, the structure of injecting tube 5, nozzle 6 and penetrate and inhale principle and be prior art; Repeat no more at this, mixture pipe 8 is installed in the other end of injecting tube 5.Cutting oxygen pipe 7 is connected to the hyperbaric oxygen spray orifice on the cutting torch 9, and mixture pipe 8 is connected to the mist spray orifice on the cutting torch 9.
Also be provided with through hole 15 and the preheat oxygen control valve installing hole 16 and acetylene control valve installing hole 17 of a upper and lower perforation on the main body 1, referring to Fig. 3, Fig. 4.
Referring to Fig. 2 and Fig. 7; The outer wall of injecting tube 5 right-hand members is provided with a through hole 51; This through hole 51 communicates with acetylene inlet 12 through acetylene path 20; Acetylene control valve installing hole 17 is communicated with acetylene path 20, and acetylene control valve 171 is installed in the acetylene control valve installing hole 17, through regulating the flow that acetylene control valve 171 can open, cut out acetylene path 20 or regulate acetylene gas in the acetylene path 20.
Combine Fig. 6 and Fig. 7 again, cutting oxygen outlet 13 communicates with oxygen intake 11 through oxygen path 16, and oxygen path 16 has first, second two branches 161,162; First branch 161 communicates with through hole 15; Second branch 162 communicates with the centre bore of nozzle 6, and (nozzle 6 has axially extending bore, i.e. centre bore, and this axially extending bore is along the airflow direction flare; So that the exit of nozzle has higher flow velocity; Nozzle 6 is screwed onto the exit of second branch 162), preheat oxygen control valve installing hole 16 communicates with second branch 162, and preheat oxygen control valve 163 is installed in the preheat oxygen control valve installing hole 16; Can open or close second branch 162 through regulating preheat oxygen control valve 163, perhaps regulate the flow of preheated oxygen in second branch 162.
Referring to Fig. 2, Fig. 6; Through hole 15 bottoms of upper and lower perforation are fitted with pilot plunger 152 through sealing-plug 151 sealings in this through hole 15, and pilot plunger 152 has a columniform body; And the middle part is provided with necking part 1521, is provided with back-moving spring 154 between pilot plunger 152 and the sealing-plug 151.The end face of main body 1 is provided with two risers 19, and above-mentioned two risers 19 lay respectively at the both sides of through hole 15, and an end of pressure handle 153 is hinged on two risers 19 and the end face of the lower surface of pressure handle 153 and pilot plunger 152 offsets.Rotate pressure handle 153 up and down along pin joint; Under the effect of back-moving spring 154, can drive pilot plunger 152 moves up and down; When pilot plunger 152 upwards resets; The barrel portion of necking part 1521 belows of its columniform body is closed the opening that communicates with first branch 161 on through hole 15 inwalls, will not have the Oxygen Flow mistake again in the cutting oxygen pipe 7 at this moment; When pilot plunger 152 moves down; The barrel portion of necking part 1521 belows of its columniform body is opened first branch 161 gradually; Oxygen flow in the cutting oxygen pipe 7 increases gradually; When the opening that to through hole 15 inwalls, communicates with first branch 161 exposed fully, the oxygen flow that leads in the cutting oxygen pipe 7 was maximum.
Among the present invention, cutting oxygen pipe 7 adopts gapless stainless steel tube with mixture pipe 8, makes this body structure of cutting torch more firm, longer service life.
When the present invention uses, open preheat oxygen control valve 163, have oxygen with certain pressure and spray into mixture pipe 8 at a high speed through injecting tube nut 6; Form vacuum around making the port of export of nozzle 6, thereby acetylene is sucked mixture pipes 8 through injecting tube 5, and after preheat oxygen fully mixes in mixture pipe 8; Mist spray orifice ejection by cutting torch 9 is lighted; After being adjusted to preheat flame through preheat oxygen control valve 163 and acetylene control valve 171 afterwards, will be cut METAL HEATING PROCESS, opened cutting oxygen valve immediately to burning-point; Cutting oxygen is through cutting oxygen pipe 7; By the hyperbaric oxygen spray orifice ejection at cutting torch 9 centers, carry out gas cutting, the gas flow of cutting oxygen is regulated through upper and lower the pressing of pressure handle 153.
The present invention is not limited to above-mentioned preferred forms, and anyone should learn the structural change of under enlightenment of the present invention, making, and every have identical or close technical scheme with the present invention, all falls within protection scope of the present invention.
