Abstract
The utility model discloses a gas proportional valve. The gas proportional valve comprises a valve body, a cover plate, a proportional valve body, an electromagnetic valve and a servo valve. The cover plate is connected with the valve body through screws. The electromagnetic valve, the servo valve and the proportional valve body are sequentially installed on the cover plate from left to right. Due to fact that the cover plate is integrally designed, the electromagnetic valve, the servo valve and the proportional valve body are installed together on the cover plate, the valve body and the cover plate are designed into a split structure, so that assembling accuracy and efficiency are improved. A coil of the electromagnetic valve and a coil of the servo valve are sealed in a plastic mode to a whole, and are installed into a same support, so that service life of the coils is improved, and assembling is simple and convenient. The gas proportional valve is improved, so that structure is compact and cost is lowered.
Description
Technical field
The utility model relates to a kind of fuel gas buring utensil, more particularly, is a kind of gas ratio valve.
Background technique
The gas flow control valve of fuel gas buring utensil is power type and air-driven type two big classes basically at present; And power type is divided into power type moveable core type, power type moving-magnetic type, power type moving coil and a kind of gas ratio valve.
There is following defective in popular a kind of gas ratio valve on China market: 1, because solenoid valve, servovalve, Proportional valve are fixed on the valve body, not only assembly precision is not high, and efficiency of assembling is low; 2, since electromagnetic valve coil with in the servovalve coil is contained in different supports respectively, so lack its working life; 3, because of being subjected to the influence of factors such as its structure, material and technology, Proportional valve bulky makes a kind of miniaturization of gas ratio valve and slimming be difficult to.
The model utility content
In order to overcome above-mentioned deficiency, the utility model purpose is to provide a kind of gas ratio valve of a kind of assembly precision and efficiency of assembling height, compact structure.
To achieve these goals, the technical solution adopted in the utility model is: a kind of gas ratio valve, include valve body, cover plate, Proportional valve, solenoid valve and servovalve, be connected by screw between cover plate and the valve body, wherein, solenoid valve, servovalve, Proportional valve are installed on the cover board successively from left to right.
Above-mentioned gas ratio valve is provided with sealing rubber pad between described cover plate and the valve body, and the periphery of described sealing rubber pad is provided with the boss of a circle sealing.
Above-mentioned gas ratio valve, described Proportional valve comprise conduit, gland, coil block, adjusting spiral shell seat, and coil block is enclosed within the periphery of conduit, regulate the end that the spiral shell seat is located at conduit, and the other end of conduit is fixed on the gland, and institute's gland riveted joint on the cover board; Proportional valve support in the described coil block is connected with seat riveted joint of adjusting spiral shell or screw.
The beneficial effects of the utility model: because cover plate adopts integrated design, solenoid valve, servovalve and Proportional valve together are contained in above the cover plate, and valve body and cover plate are designed to split-type structural, and its benefit improves assembly precision and efficient exactly; Electromagnetic valve coil becomes disjunctor with servovalve coil plastic packaging, together puts in the twin coil C type support, and its benefit is exactly the electrical quality and the working life of improving coil, makes that simultaneously assembling is more easy; In order to improve electrical properties, solenoid valve conduit and solenoid valve are decided magnetic core and are riveted together; Proportional valve has been done improvement, makes structure compact more, but also reduces cost.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1, be structural representation of the present utility model.
Among the figure: 1. valve body; 2. filter screen; 3. glue is clapped; 4. solenoid valve spring; 5. sealing rubber pad; 6. cover plate; 7. solenoid valve; 8. support; 9. electromagnetic valve coil; 10. solenoid valve conduit; 11. decide magnetic core; 12. servovalve filter screen; 13. bonnet; 14. valve seat; 15. servovalve apical axis; 16. servovalve magnetic core; 17. servovalve conduit; 18. servovalve; 19. servovalve coil; 20. regulate the spiral shell seat; 21. ratio valve actuation magnetic core; 22. coil block; 23. Proportional valve is decided magnetic core; 24. conduit; 25. Proportional valve push rod; 26. Proportional valve; 27. Proportional valve support; 28. gland; 29. main film; 30. Proportional valve sealing plug.
Embodiment
As shown in Figure 1, a kind of gas ratio valve includes valve body 1, cover plate 6, Proportional valve 26, solenoid valve 7 and servovalve 18, is connected by screw between cover plate 6 and the valve body 1, and solenoid valve 7, servovalve 18, Proportional valve 26 are installed on the cover plate 6 successively from left to right.
Be provided with sealing rubber pad 5 between cover plate 6 and the valve body 1, the periphery of described sealing rubber pad 5 is provided with the boss of a circle sealing.
Working principle: after combustion gas is filtered through filter screen 2 by air intake, arrive first order valve; After the solenoid valve energising, first order valve open, combustion gas and then enters; After the servovalve energising, combustion gas enters the servo pressure chamber through the second road strainer filtering, servo valve port thus, and another road then enters main film 29 inner chambers; When the combustion gas delivery pressure is higher than predefined value, Proportional valve diaphragm chamber pressure raises, volume increases, lift on the main film 29, open the servo pressure chamber, reduced the pressure of servo gas circuit, just reduced the gaseous-pressure that enters the main film inner chamber, make the main valve aperture reduce, thereby make the combustion gas delivery pressure get back to predefined value; Conversely, when the combustion gas delivery pressure is lower than predefined value, Proportional valve diaphragm chamber pressure reduces, volume reduces, and diaphragm presses down, and closes the servo pressure chamber, improved the pressure of servo gas circuit, just improved the gaseous-pressure that enters the main film inner chamber, made the main valve aperture increase, thereby make the combustion gas delivery pressure get back to predefined value.
