Description
Technical field
The present invention relates to a kind of gas-heating water heater more particularly to a kind of full Pre-coagulations equipped with air inlet voltage regulation adjustor
Formula gas-heating water heater belongs to water heater field.
Background technique
The pressure that country's combustion gas is registered one's residence at present is different in Various Seasonal, different regions, different floors, and is premixed entirely cold
Solidifying formula gas-heating water heater is due to combustion characteristics, and tighter to admission pressure fluctuation area requirement, it is complete pre- that this adds increased debugging
The difficulty of mixed condensation-type gas-fired heating water heater.Full pre-mix condensing gas-heating water heater product is all by national standard when leaving the factory
Gaseous-pressure carries out combustion system debugging factory；And gaseous-pressure and normal pressure are that there is any discrepancy in different user man,
Therefore (adjustment carried out to flue gas content detection and combustion conditions) must be adjusted again to the product installed in user family,
The adjustment is only applicable in current gaseous-pressure and combustion gas makings；But actual conditions change at any time, when winter and summer
The pressure of registering one's residence of combustion gas is different (usually winter is low, summer is high).
Full premixed condensed water heater for heating product is in whole work process, mainly by blower, gas proportion regulating valve (gas
Ejector half valve) and venturi mixer completes combustion gas jointly and the mixed proportion of air capacity is constant.When rotation speed of fan variation, by shadow
Ring air volume, so as to cause on gas ratio valve at air sample of signal mouth pressure size variation, and air signal pressure
The size of power can cause the size of driving adjustment servo valve opening again, cause the variation for supplying the size of gas quantity, believe in air
Number a linear relationship is established between pressure and gaseous-pressure；But when rotation speed of fan it is constant on a certain revolving speed when, if at this moment
Combustion gas rises in gas ratio valve inlet pressure, complete machine burning load will be caused to increase, flue gas emission index exceeding standard, burner
Condition degenerates；It is debugged again if do not done, machine can generate burning detonation, combustion flashback, the problems such as finally resulting in machine breakdown.
Summary of the invention
In order to solve problem above, the full Pre-coagulation formula equipped with air inlet voltage regulation adjustor that the object of the present invention is to provide a kind of
Gas-heating water heater, for the water heater at different regions, different floors, Various Seasonal, the admission pressure in user family is different
Or when fluctuating larger, remain that the pressure of gas proportion valve air gate, flow are constant, guarantee complete machine thermic load not with gas pressure
Fluctuation and change, the load of complete machine only linearly changes with rotation speed of fan.
In order to achieve the goal above, the technical solution adopted by the present invention:
