Abstract
In order to solve Problems existing in existing Air-regulating valves, the purpose of this utility model is to provide a kind of Air-regulating valves of electromagnetic valve.Many grades of Air-regulating valves of this electromagnetic valve are made up of valve body, fuel gas inlet, air inlet branch road, valve chamber, solenoid valve, combustion gas mouth, branch road of giving vent to anger, gas outlet.After fuel gas inlet passes into combustion gas, combustion gas evenly enters air inlet branch road, and the situation lower piston that solenoid valve is not energized seals inlet hole, when solenoid valves combustion gas by valve chamber, enter air outlet hole, through combustion gas mouth, branch road of giving vent to anger until gas outlet.Solenoid valve is not energized, being energized to be combined into the path of multiple different combustion gas mouth pore size, thus realizes the adjustment to gas flow.
Description
Technical field
The utility model relates to a kind of gas control valve, specifically a kind of gas control valve by electromagnetic valve combustion gas throughput.
Background technique
Current, the valve body of most of gas control valve is formed by shell with the rotary spool that its inner chamber matches.The axial cross section of shell inner cavity is trapezoidal, and Qi Bishang has manhole; Spool profile is mated with shell inner cavity, its inside be hollow to connect fuel gas pipeline, the wall of spool has multiple through hole, through hole along spool cylindrical circumferencial direction distribution, height consistent with outer casing through hole, aperture is successively from small to large.By the rotation of spool, the hole of different pore size on spool is communicated with the hole on shell, realizes the control of gas outlet amount.Manually can rotate, also can be rotated by stepper motor and motor.Manual rotation is difficult to ensure that the hole of spool is aimed at the hole of shell, and is difficult to realize automation; Stepper motor is adopted to be difficult to accomplish that valve body is returned to zero point after work; Adopt motor, the scheme (patent CN200820216908.6) of Hall transducer that gear transmission and monitoring gear rotate, it controls complexity, and structure breaks down and just can not guarantee that valve makes zero and cause leaking gas to have potential safety hazard.
Summary of the invention
In order to solve Problems existing in existing Air-regulating valves, the purpose of this utility model is to provide a kind of many grades of Air-regulating valves of electromagnetic valve.
To achieve these goals, embodiment of the present utility model is as follows:
The utility model is made up of fuel gas inlet, air inlet branch road, valve chamber, solenoid valve, gas quantity control valve, gas outlet.It is characterized in that, fuel gas inlet is connected with several air inlet branch road, and the other end of each air inlet branch road is connected with valve chamber.Gas quantity control valve one end connects valve chamber, and the other end connects gas outlet.Solenoid valve is arranged on valve body, and piston is in valve chamber, and piston can free-extension motion in valve chamber.When not being energized, piston stretches out under the action of the spring, and at this moment air inlet branch road and gas quantity control valve are split by piston and disconnect; During energising, piston is regained under the effect of electromagnetic force, and air inlet branch road is communicated with gas quantity control valve.
Wherein: the piston of solenoid valve is soft, wear-resisting rubber;
In force, after fuel gas inlet passes into combustion gas, combustion gas evenly enters air inlet branch road to the utility model, and the situation lower piston that solenoid valve is not energized seals gas-entered passageway, when be energized combustion gas by valve chamber, enter gas quantity control valve, until gas outlet.Solenoid valve is not energized, being energized to be combined into the path of multiple different combustion gas mouth pore size, thus realizes the adjustment to gas flow.
The utility model has some benefit following: the accurate control one, realizing combustion gas.Two, adopt the mode of solenoid valve to reduce mechanical transmission structure, there is higher reliability.Three, solenoid valve access failure, connect this binary mode carry out combustion gas regulate be easy to realize automatic control.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is described further.
Fig. 1 is the front view of the utility model embodiment;
Fig. 2 is the plan view of the utility model embodiment;
Fig. 3 is the cross-sectional schematic (not having solenoid valve) along A-A line in Fig. 1.
Fig. 4 is the cross-sectional schematic (being in a grade) along B-B line in Fig. 2.
Embodiment
As Fig. 1-Fig. 4, in the present embodiment, select 3 solenoid valves.Fuel gas inlet 1 connects gas inlet pipe, and three air inlet branch road 2 one end are connected with fuel gas inlet 1, the other end is connected with valve chamber 3, and inlet hole 4 is on valve chamber 3 side.Solenoid valve 5 is arranged on valve body 6, and its piston 7 is in valve chamber 3, and piston is soft, wear-resisting rubber, can the gas outlet hole 8 of sealed bottom.Valve chamber is cylindrical, and the connecting rod 9 of solenoid valve 5 has spring 10, and when solenoid valve 5 is not energized, connecting rod 9 extends under the effect of spring 10, and piston 7 is in bottom valve chamber 5, gas outlet hole 8; When solenoid valve 5 is energized, connecting rod 9 is regained, and piston 7 is away from bottom.In the utility model, combustion gas tolerance control valve 11 is formed by connecting by the pipeline of three sections of different tube diameters, the convenience of the processing mainly considered, the pipe of the thinnest middle one end is for controlling the flow of combustion gas, as required, in this example, this pipe caliber is from left to right respectively 1.4mm, 1.7mm, 2.0mm.Three combustion gas tolerance control valves 11 are communicated with gas outlet 12.
Solenoid valve base has flange, is convenient to be connected with burner.
When adjusting fire to one grade, the solenoid valve 5 in the valve chamber 3 that combustion gas tolerance control valve 11 caliber connects for 1.4mm is opened, and two other solenoid valve 5 cuts out, and the air inlet branch road 2 only having this to be connected with valve chamber is communicated with combustion gas tolerance control valve 11, only has a fuel gas path;
When adjusting fire to second gear, the solenoid valve 5 in the valve chamber 3 that combustion gas tolerance control valve 11 caliber connects for 1.7mm is opened, and two other solenoid valve 5 cuts out, and the air inlet branch road 2 only having this to be connected with valve chamber is communicated with combustion gas tolerance control valve 11, only has a fuel gas path;
When adjusting fire to third gear, the solenoid valve 5 in the valve chamber 3 that combustion gas tolerance control valve 11 caliber connects for 2.0mm is opened, and two other solenoid valve 5 cuts out, and the air inlet branch road 2 only having this to be connected with valve chamber is communicated with combustion gas tolerance control valve 11, only has a fuel gas path;
When adjusting fire to fourth gear, the solenoid valve 5 in the valve chamber 3 that combustion gas tolerance control valve 11 caliber connects for 1.4mm and 1.7mm is opened, and another one solenoid valve 5 cuts out, and now has two-way blast tube;
When adjusting fire to five grades, the solenoid valve 5 in the valve chamber 3 that combustion gas tolerance control valve 11 caliber connects for 1.7mm and 2.0mm is opened, and another one solenoid valve 5 cuts out, and now has two-way blast tube;
When adjusting fire to six grades, solenoid valve 5 is opened entirely, now has three road blast tubes.
Realized the tune fire of six gears by said structure, most demand adjusting fire can be met.When solenoid valve is increased to four, there are 15 kinds of integrated modes, can realize adjusting fire more accurately.
