Description
Technical field: the present invention relates to a kind of combustion gas of combustion gas tool and the combustion gas and the air certainty ratio control valve of air certainty ratio control valve, particularly a kind of gas heater.
Background technology: along with the development of combustion gas tool, the thermal efficiency and environmental requirement to the combustion gas tool are more and more higher, therefore fully-premixed combustion technology has appearred, this full premix technology is exactly after air and combustion gas are mixed in the premix chamber by a certain percentage fully, burn to burner again, air capacity is the requirement of combustion gas reality, and ratio between the two also will keep definite value when using power to change in the combustion gas tool, and this just requires to use combustion gas/air certainty ratio control valve to implement.Use the gas heater of full premix combustion technology at present, great majority adopt mechanical gas/AIR Proportional valve, promptly on the system either road, set a choke block, the choke block both sides form a pressure difference signal Δ Pa, be that the mechanical type proportioning valve is by detected pressure signal, by the servo-assisted mechanism of valve internal pressure, open gas valve according to a certain percentage coefficient adjustment lead to the gaseous-pressure Pg of burning, the flow that makes combustion gas in the whole combustion process all keeps certain ratio with the ratio of the flow of air.Mechanical gas/AIR Proportional valve is for guaranteeing uniformity and adapting to different combustion gas gas kinds, should be provided with that magnification ratio is regulated and zero point governor motion, structure is very complicated, requirement accuracy of manufacture height, add the technical sophistication of electric-control system, need the price of dc fan, system of adjustable speed higher, also can't large-scale popularization use in the recent period.For overcoming these defectives, the combustion gas and the air certainty ratio control valve of combustion gas tool are studied.
Summary of the invention: technical problem to be solved by this invention is combustion gas and the air certainty ratio control valve that a kind of combustion gas tool will be provided, and it is simplified structure, reduction manufacturing cost effectively.
The technical scheme that the present invention solves its technical problem employing is:
It comprises valve body, fuel gas inlet, cut-off electromagnetic valve, gas outlet, air intlet, air outlet slit, it also comprises pressure regulator valve, combustion gas control dish valve, bindiny mechanism, air control dish valve, stepper motor, pressure regulator valve, combustion gas control dish valve, bindiny mechanism, air control dish valve and stepper motor are installed on the valve body respectively, fuel gas inlet, cut-off electromagnetic valve, pressure regulator valve, combustion gas control dish valve links to each other with gas outlet and constitutes blast tube, air intlet, air control dish valve links to each other with air outlet slit and constitutes air duct, combustion gas control dish valve is connected with air control dish valve by bindiny mechanism, and by the stepper motor driving combustion gas control dish valve and air control dish valve is opened and closed synchronously.
Described bindiny mechanism is axle or gear drive etc.
The video disc of the video disc of described combustion gas control dish valve and air control dish valve is provided with the hole.
Described hole is hole or groove etc.
The present invention compares the beneficial effect that is produced with background technology:
1, because the present invention adopts valve body, fuel gas inlet, cut-off electromagnetic valve, gas outlet, air intlet, air outlet slit, pressure regulator valve, combustion gas control dish valve, bindiny mechanism, air control dish valve, the structure of stepper motor, by driving stepper motor combustion gas control dish valve and air control dish valve are opened and closed synchronously, simple in structure, the accuracy of manufacture is easy to reach, require supporting electric-control system technology simple, do not need the speed-governing dc blower fan, cheap, so it is simplified structure effectively, reduce manufacturing cost, and dependable performance, the cost performance height, but large-scale popularization is used.
Description of drawings: Fig. 1 is a structural representation of the present invention.
The thermostatic control system control flow chart that Fig. 2 uses on gas heater for the present invention.
The specific embodiment: shown in accompanying drawing 1, the present invention includes fuel gas inlet 1, cut-off electromagnetic valve 2, pressure regulator valve 3, combustion gas control dish valve 4, bindiny mechanism 5 (present embodiment is axle), air outlet slit 6, gas outlet 7, air control dish valve 8, stepper motor 9, air intlet 10 and valve body 11.Wherein cut-off electromagnetic valve 2, pressure regulator valve 3, combustion gas control dish valve 4, bindiny mechanism 5 (present embodiment is axle), gas outlet 7, air control dish valve 8 and stepper motor 9 are installed in respectively on the valve body 11; Combustion gas control dish valve 4, air control dish valve 8 all link to each other with stepper motor 9 by bindiny mechanism 5 (present embodiment is an axle); Fuel gas inlet 1, cut-off electromagnetic valve 2, pressure regulator valve 3, combustion gas control dish valve 4 link to each other with gas outlet 7; Air intlet 10, air control dish valve 8 link to each other with air outlet slit 6.Can be provided with hole (hole or groove etc.) on the video disc of the video disc of combustion gas control dish valve and air control dish valve, the gas quantity and the air capacity of minimum load during with the assurance water heater working.
Its course of work is: open cut-off electromagnetic valve 2, combustion gas is entered by fuel gas inlet 1, and the cut-off electromagnetic valve 2 of flowing through flows out the back by gas outlet 7 then and mixes with air; The air of flowing through after air is entered by air intlet 10 control dish valve 8 is flowed out by air outlet slit 6, and present embodiment is that gaseous mixture was flowed out by air outlet slit 6 after air and gas outlet 7 flowed out combustion gas mixing; After giving stepper motor 9 combustion gas tool (as water heater etc.) automatically controlled signal, stepper motor drives combustion gas control dish valve 4 by bindiny mechanism 5 (present embodiment is an axle) and air is controlled the dish valve 8 certain corner of rotation synchronously, thus the size of synchronous change gas flow and air mass flow; Can corresponding change combustion gas and the ratio value of air by regulating pressure regulator valve 3, and carry out regulating zero point gentle kind and regulate.
Shown in accompanying drawing 1, accompanying drawing 2, during this system works, AC blower fan VE input pressure Pa is to the air intlet 10 of gaseous fuel fixed proportional valve MFC G/A, and combustion gas is entered in the gas-air certainty ratio valve by fuel gas inlet 1.Set the leaving water temperature Tp of gas heater, calculating by ECU CE, the output automatically controlled signal L give stepper motor SM, stepper motor output is decided the torque M of corner and is given combustion gas and AIR Proportional valve, open the combustion gas control dish valve 4 and the air control dish valve 8 that are fixedly installed in the valve synchronously, two dish opening of valves corners are identical, air mass flow Qa, the gas flow Qg of output certainty ratio.Air mass flow Qa and gas flow Qg carry out heat exchange with water in heat-exchange system S after entering burner combustion after the mixing, output water temperature is the hot water of T.The channel diameter of two dish valves is determined in the ratio that gas-air completing combustion needs.
