In the utility model, because the gas cavity of the traditional gas pipe, which is connected with the nozzle, is isolated into two independent or more than two independent gas chambers, and the quantity of the gas supply nozzles is changed by closing or opening the electromagnetic valves at the inlets of some of the gas chambers; thus, the segmental opening and closing control of the gas inlet quantity can be realized, the temperature regulating range is widened and the constant temperature effect is achieved thereby.
Description
Technical field
The utility model relates to burner, and the intelligent constant-temperature gas heater of magnetic valve is housed on especially a kind of tracheae.
Background technology
At present, the water heater complete machine structure mainly by burner, heat-exchange device, control device, fume extractor, tracheae, housing, igniter, water out adapter, water supply connector, blower fan, combustion gas ratio adjusting valve, leaving water temperature sensor, water flow sensor, go into water temperature sensor and constitute, its course of work is: when opening feed cock (or depotition cock), water just flows through water supply connector, water flow sensor, heat exchanger, flows out through the delivery port of water out adapter by water inlet.When inflow acquires a certain degree (3.0 ± 0.5L/min), water flow sensor can perceive this flow, output signal to master control system, make the blower fan entry into service, clean (about 1.5S) in advance, after the pre-cleaning, electric discharge device begins discharge, then, magnetic valve on the combustion gas ratio adjusting valve is opened, and combustion gas enters tracheae to burner by the combustion gas ratio adjusting valve, after the electric spark of being emitted by electric discharge device from its burning fire hole combustion gas of overflowing is lighted, gas heater is started working, and waste gas producedly behind the fuel gas buring receives external chimney by fume extractor and drains into outdoor.If do not light combustion gas at the appointed time, then safety control is started working, and closes the magnetic valve on the combustion gas ratio adjusting valve, cuts off fuel gas path, stops discharge simultaneously.In the use of hot water, variation because of water yield, water temperature, hydraulic pressure etc., change and cause institute to go out the hot water temperature, the leaving water temperature sensor can detect automatically, then data is passed to master control system, and master control system is according to the hot water temperature of going out, inflow temperature, the water yield, calculate and be provided with the difference of temperature, again this difference is passed to gas ratio valve, regulate gas quantity, to keep set hot water temperature.But in actual use, be subjected to technical conditions and Effect of Environmental, the intelligent constant-temperature gas heater is difficult to reach the constant temperature effect, when particularly summer, water supply gets caused the on the low side and cold water temperature that advanced of hydraulic pressure higher, just need transfer air inflow very little, cause that flame diminishes on the single burning plate, be subjected to the blower fan windage this moment, tend to cause phenomenons such as flame-out, thermal efficiency reduction, make water heater be difficult to operate as normal.At above-mentioned situation, specially designed a kind of technical scheme promptly adds magnetic valve on tracheae intelligent constant-temperature gas heater.
Summary of the invention
The purpose of this utility model provides a kind ofly can carry out block switch control to air inflow, the thermoregulation range of water heater is widened, thereby reach the intelligent constant-temperature gas heater that on tracheae, has magnetic valve of constant temperature effect, solved existing intelligent constant-temperature gas heater when air inflow is transferred very for a short time, because single burning plate flame is little, tends to cause flame-out problem when being subjected to the blower fan windage.
In order to achieve the above object, the technical solution of the utility model is: the intelligent constant-temperature gas heater that magnetic valve is housed on a kind of tracheae, comprise burner, heat-exchange device, control device, fume extractor, tracheae, housing, igniter, water out adapter, water supply connector, blower fan, the combustion gas ratio adjusting valve, the leaving water temperature sensor, water flow sensor, go into water temperature sensor, wherein the air cavity that is connected with nozzle of tracheae is isolated into the air chamber more than 2 or 2, each air chamber communicates with tracheae respectively, one of them air chamber directly communicates with tracheae, other air chamber is equipped with magnetic valve at air inlet, and this magnetic valve connects control device through lead.
This programme is connected traditional tracheae with nozzle air cavity is isolated into the independently air chamber more than 2 or 2, and each air chamber communicates with tracheae respectively, one of them air chamber directly communicates with tracheae, other air chamber is equipped with magnetic valve at air inlet, because the air cavity that traditional tracheae is connected with nozzle is isolated into a plurality of air chambers, except an air chamber and tracheae are straight-through, the porch of other air chamber all is equipped with magnetic valve, thereby can be by closing or opens solenoid valve is carried out block switch control to air inflow, thereby realize the nozzle air feed work of some, and thermoregulation range is widened, like this, when the intelligent constant-temperature gas heater when air inflow is transferred very for a short time, can close the magnetic valve of some air chambers, make the work of a spot of nozzle air feed, like this, owing to have only the work of a spot of nozzle air feed, thereby can guarantee that under the condition of same tracheae air feed single burning plate flame is big, immediately be subjected to the blower fan windage and also can not cause flame-out phenomenon, thereby reach the constant temperature effect.
The utility model has the advantages that: because the air cavity that traditional tracheae is connected with nozzle is isolated into the independently air chamber more than 2 or 2, by closing or open the magnetic valve of some air chamber porch, change the quantity of spray nozzle of the gas supply, thereby realize air inflow is carried out block switch control, the thermoregulation range of water heater is widened, and then reached the constant temperature effect.
