Description
Technical field
The present invention relates to a kind of valve member, relate in particular to a kind of gas mixing valve that is applied to the thermal deburring bed.
Background technique
The thermal deburring bed is to utilize after the igniting of combustion gas and oxygen mix in the firing chamber implode, utilizes the High Temperature High Pressure of explosion time that the burr of workpiece in firing chamber is removed.When gas mixes, require proportioning even; During igniting, require igniting reliable; Explosion time, require valve seal good; Simultaneously, the emission request of combustible gas is slowly steady, in order to avoid cause unnecessary igniting.Mixing valve can be for the break-make of controlling turnover firing chamber gas and the mixing of combustion gas and oxygen, and rational structural design can provide safety assurance for tightness and the reliability of system.
Summary of the invention
Purpose of the present invention just is 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 produced due to lathe igniting blast failure or other reasons.
The following technological scheme of the concrete employing of the present invention:
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 the middle with hole column, and three spools are clamped in valve seat separately and realize the conical surface seal between spool and valve seat by a binding clasp be arranged on valve body respectively, be respectively arranged with Sealing between three spools and valve body, realize spool and extraneous sealing, the valve seat front-end face is convex structure, with the valve inner press seal, be connected, be provided with spool in valve body and do the hole of turnover motion, leading role by described hole guarantees the coaxality between spool and valve seat, be provided with the blast tube communicated with the external world in valve body, oxygen channel, exhaust passage and the gas hybrid channel communicated 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 the gas hybrid channel, between exhaust passage and blast tube, by air flue, communicate.
Mixing valve of the present invention 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 the 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, the original paper long service life; The gas hybrid channel of design, mix gas, and igniting is reliable; Design the air flue with throttling action between exhaust passage and blast tube, 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; Simultaneously, 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 solution of the present invention is described in further detail.
As shown in Figure 1 and Figure 2, mixing valve mainly is 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 the middle with hole column, generally selects softer metal material, as copper.Valve seat 5 front-end faces are designed to convex, for realization, with the press seal between valve body 7 inside, are 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, is controlled.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 communicated with the external world.The interior bottom of valve body 7 is provided with the gas hybrid channel 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.The inflammable gas that discharge due to the needs that explode unsuccessfully or other reason produces for output exhaust passage.Valve seat 5 rear ends of fuel gas valve core 3, oxygen spool 12 and exhaust plug 13 are offered porose, with blast tube, oxygen channel, exhaust passage, are communicated with respectively.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 the air flue 6 with 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 that accident needs the 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 from relatively safety discharge slowly of relief opening 15 by air flue 6.
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 requirement of the present invention.
