The technical solution adopted in the utility model, utilize connection and the closedown of underground heat gauge tap, the water pump and the scavenger fan that control gas fired-boiler quit work, and during local hot temperature control adhesive, 220V voltage is through resistance R1 step-down, diode D1 rectification, wave filter C1 filtering, then through resistance R2 for triode Q1 provides reference voltage, the adhesive of Q1 turn-on relay, boiler works, otherwise then stops.Therefore not only can economize energy, and can environmental pollution be reduced.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is further described:
Fig. 1 is circuit structure diagram of the present utility model.
Detailed description of the invention
As shown in Figure 1, family expenses underground heat gas fired-boiler control circuit, comprise the relay 5, the triode Q1 of control relay adhesive, the decompression rectifier filter circuit that control boiler break-make, described decompression rectifier filter circuit access underground heat temperature controller, the colelctor electrode of described triode Q1 is connected with relay 5; During local hot temperature controller adhesive, described decompression rectifier filter circuit by after 220V voltage step-down rectifying and wave-filtering for triode Q1 provides reference voltage, after triode Q1 conducting, relay 5 adhesive also controls boiler work, and after triode Q1 ends, relay disconnected 5 leaves and controls boiler and quits work.
Wherein, relay 5 is powered by power circuit, described power circuit comprises transformer 1, rectifier bridge 2, wave filter 3 and voltage-stablizer 4,220V alternating voltage after transformer 1 step-down, rectifier bridge 2 rectification, wave filter 3 filtering and voltage-stablizer 4 voltage stabilizing for relay 5 provides 12V direct current.Described decompression rectifier filter circuit comprises step-down rectifier module and diode D2, wave filter C1, the resistance R2 of some groups of resistance R1 and diode D1 composition, the resistance R1 often organized and diode D1 connects, diode D2, wave filter C1, resistance R2 and step-down rectifier model calling, resistance R2 accesses the base stage of triode Q1.
During local hot temperature control adhesive, 220V voltage through resistance R1 step-down, diode D1 rectification, wave filter C1 filtering, then through resistance R2 for triode Q1 provides reference voltage, the adhesive of Q1 turn-on relay, boiler work, otherwise then stop.Therefore, when boiler stops burning, the water pump of boiler and scavenger fan will quit work, thus reach the object in energy-conserving and environment-protective and extension device service life.
