The purpose of this utility model is just to provide a kind of mixing valve, for the mixing of the combustion gas of thermal deburring bed and oxygen, and the discharge of the inflammable gas producing due to lathe igniting blast failure or other reasons.
The following technological scheme of the concrete employing of the utility model:
A kind of mixing valve, comprise valve body, characterized by further comprising fuel gas valve core, oxygen spool, exhaust plug and valve seat separately, binding clasp and Sealing, fuel gas valve core, oxygen spool and exhaust plug front end are cone structure, three valve seats are middle with hole column, and three spools are clamped in and in valve seat separately, realize the conical surface seal between spool and valve seat by a binding clasp being arranged on valve body respectively, between three spools and valve body, be respectively arranged with Sealing, realize spool and extraneous sealing, valve seat front-end face is convex structure, be connected with valve inner press seal, in valve body, be provided with spool and do the hole of turnover motion, leading role by described hole guarantees the coaxality between spool and valve seat, in valve body, be provided with the blast tube communicating with the external world, oxygen channel, exhaust passage and the gas hybrid channel communicating with firing chamber, fuel gas valve core, the valve seat rear end of oxygen spool and exhaust plug respectively with blast tube, oxygen channel, exhaust passage communicates, fuel gas valve core, the valve seat front end of oxygen spool communicates with gas hybrid channel, between exhaust passage and blast tube, by air flue, communicate.
Mixing valve of the present utility model is mainly by three groups of spool valve base sealing module compositions, for mixing of the break-make of control combustion chamber gas and combustion gas and oxygen.
Three groups of forms that spool valve seat seals by inner hole cone of this mixing valve, spool selects with valve seat the material that soft or hard is different, and sealing reliability is good, and stain resistance is strong, original paper long service life; The gas hybrid channel of design, mixes gas, and igniting is reliable; Between exhaust passage and blast tube, design the air flue with throttling action, made exhaust steadily slow, strengthened the Security of equipment.
Structurally, exhaust plug and oxygen spool, fuel gas valve core are arranged on a valve body, simple and compact for structure, reduced unnecessary pipeline and connected.Binding clasp is as adopted the form of one-way cylinder, and simple in structure, volume is little; Meanwhile, three binding clasps are arranged on a support, and have adopted easily detachable structure, make the maintenance of equipment and change all more convenient.

Embodiment
Embodiment one
Below in conjunction with accompanying drawing, technical solutions of the utility model are described in further detail.
As shown in Figure 1 and Figure 2, mixing valve is mainly comprised of valve body 7, fuel gas valve core 3, oxygen spool 12, exhaust plug 13 and valve seat separately 5 thereof etc., is mainly used in realizing the combustion gas of thermal deburring bed and mixing and charging and discharging 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 faces are designed to convex, for realize with valve body 7 inside between press seal be connected.
Three spools 3,12,13 are clamped in separately and realize the conical surface seal between spool and valve seat in valve seat 5 rear end endoporus by the larger binding clasp 14 of exerting oneself respectively.Binding clasp 14 can adopt one-way cylinder or other structures, by hydraulic power 1, controls.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.
The interior middle part of valve body 7 is provided with blast tube, oxygen channel, the exhaust passage communicating with the external world.The interior bottom of valve body 7 is provided with the gas hybrid channel 9 communicating 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 discharging due to the needs that explode unsuccessfully or other reason produces.Valve seat 5 rear ends of fuel gas valve core 3, oxygen spool 12 and exhaust plug 13 are offered porose, are 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 hybrid channel 9.Aperture, 9 one of gas hybrid channels communicates with firing chamber 8.Combustion gas, oxygen enter valve body 7 by blast tube, oxygen channel respectively, then are input to firing chamber 8 by gas hybrid channel 9.Between exhaust passage and blast tube, by thering is the air flue 6 of throttling action, communicate.The internal orifice dimension of air flue 6 is smaller, plays throttling action while its role is to exhaust, and gas is discharged more slowly, to prevent unnecessary igniting.Gas hybrid channel 9 also has place, an aperture that spark plug 10 is installed, and 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 mix gas hybrid channel 9 and enters firing chamber 8.After having inflated, binding clasp clamps fuel gas valve core 3 and oxygen spool 12, and fuel gas valve core 3 and oxygen spool 12 are closed, and firing chamber 8 cuts off with extraneous pipeline, by spark plug 10 igniting, realizes gaseous detonation in firing chamber, and burr on workpiece is removed.When light a fire blast failure or equipment occur surprisingly need to discharging 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 from relatively safety discharge slowly of relief opening 15 by air flue 6.
In addition to the implementation, the utility model 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 the utility model requirement.
