Embodiment
Embodiment one
Below in conjunction with accompanying drawing, technical solution of the present invention is described in further detail.
As shown in Figure 1 and Figure 2, mixing valve, primarily of compositions such as valve body 7, fuel gas valve core 3, oxygen spool 12, exhaust plug 13 and respective valve seats 5 thereof, is mainly used in realizing the combustion gas of thermal deburring bed and mixing and charge and discharge of oxygen.
Three spools 3,12,13 are column structure, and its front end is cone structure, generally selects harder metal material, as steel.Valve seat 5 is middle with hole column, generally selects softer metal material, as copper.Valve seat 5 front-end face is designed to convex, is connected for the press seal realized between valve body 7 inside.
Three spools 3,12,13 are clamped in the endoporus of respective valve seat 5 rear end the conical surface seal realized between spool and valve seat respectively by a binding clasp of exerting oneself larger 14.Binding clasp 14 can adopt one-way cylinder or other structures, is controlled by hydraulic power 1.Three binding clasps 14 are arranged on valve body 7 by support 2, and the mounting type of support 2 adopts groove-fastening type structure for convenience detach.
Valve body 7 internal upper part is provided with three holes, hole internal diameter and spool external diameter match, three spools 3,12,13 can do turnover motion respectively in three holes, the leading role of interior three holes of valve body 7 can ensure three spools 3,12,13 and its coaxality separately between valve seat 5, reaches reasonable sealing effect.Three spools 3, to seal by Sealing 16 between 12,13 and valve body 7.
In valve body 7 middle part be provided with communicate with the external world blast tube, oxygen channel, exhaust passage.In valve body 7, bottom is provided with the gas and vapor permeation passage 9 communicated with firing chamber.Blast tube is connected with extraneous fuel gas source 4, for inputting combustion gas.Oxygen channel is connected with extraneous source of oxygen 11, for inputting oxygen.Exhaust passage is for exporting the inflammable gas of the needs discharge due to explode failure or the generation of other reason.Valve seat 5 rear end of fuel gas valve core 3, oxygen spool 12 and exhaust plug 13 is offered porose, is communicated with respectively with blast tube, oxygen channel, exhaust passage.The valve seat front end of fuel gas valve core 3, oxygen spool 12 communicates with gas and vapor permeation passage 9.Gas and vapor permeation passage 9 one apertures communicate with firing chamber 8.Combustion gas, oxygen enter valve body 7 respectively by blast tube, oxygen channel, then are input to firing chamber 8 by gas and vapor permeation passage 9.Air flue 6 by having throttling action between exhaust passage with blast tube communicates.The internal orifice dimension of air flue 6 is smaller, plays throttling action, gas is discharged more slowly, to prevent unnecessary igniting when its role is to exhaust.Gas and vapor permeation passage 9 also has aperture place to install spark plug 10, is convenient to realize igniting.
During the inflation of thermal deburring bed, the binding clasp of fuel gas valve core 3 and oxygen spool 12 unclamps, and fuel gas valve core 3 and oxygen spool 12 are opened, and combustion gas and oxygen enter after gas and vapor permeation passage 9 mixes and enters firing chamber 8.After having inflated, fuel gas valve core 3 and oxygen spool 12 clamp by binding clasp, and fuel gas valve core 3 and oxygen spool 12 are closed, and firing chamber 8 and extraneous pipeline cut off, and realize gaseous detonation in firing chamber, removed by burr on workpiece by spark plug 10 igniting.When igniting blast failure or equipment occur surprisingly needing to discharge combustible gas, the binding clasp of fuel gas valve core 3 and exhaust plug 13 unclamps, fuel gas valve core 3 and exhaust plug 13 are opened, and combustible gas enters exhaust passage by air flue 6 and discharges slowly relatively safely from relief opening 15.
In addition to the implementation, the present invention can also have other mode of executions.All employings are equal to the technological scheme of replacement or equivalent transformation formation, all drop on the protection domain of application claims.
