Abstract
The utility model provides an automatic cycling controller of a boiler matching with a water pump of the boiler, and comprises a direct current voltage-stabilized power (1). The technical proposal is that a relay tip J (1-1) is connected in series with a water pump (3), and the operation of the relay tip J (1-1) is controlled by a control circuit (2). The utility model has the advantages of simple structure, convenient manufacture and use, adjustable temperature, stabilization and reliability, economy and practicality, thereby being suitable for popularization and capable of making reasonable use of energies and avoiding a waste.
Description
The utility model relates to a kind of control device, particularly relates to a kind of control device of boiler water pump power supply.
Fast development along with the Northeast's town development, seeing day by day that the Xiao Lou employing boiler of single household is warmed oneself is many, for making the heating installation heat radiation evenly, improving whole heat supply level all is to utilize water pump in self-induction boiler water comparative heat, connect pump power and force the water in the boiler in pipeline, to circulate, again power supply is disconnected when feeling similar.So not only make troubles, and temperature is also uncontrollable to the user.Even can not reasonable energy utilization, cause the waste of electrical heat energy.
The purpose of this utility model is to use not only convenient but also save trouble in order to provide a kind of, but and reasonable energy utilization avoid waste, make the boiler water automatic cycle controller of boiler of circulation and control water temperature automatically.

This utility model is owing to taked the foregoing circuit structure, utilize thermistor be the variation of boiler water temperature come the control relay coil energising whether and then the working power of control water pump, to realize the automatic circulation of boiler water, the reliable goal of the invention that realizes, and it is simple to have project organization, make easy to use, reasonable energy utilization, economical and practical, advantages such as suitable popularization.
Below in conjunction with accompanying drawing scheme of the present utility model is described in further detail:
Fig. 1 is the circuit diagram of the automatic cycle controller of boiler.
By the automatic cycle controller of boiler shown in Figure 1 is to be made of voltage-stabilized power supply 1 and control circuit 2 two parts substantially, and wherein voltage-stabilized power supply 1 is through resistance R with alternating current 220V

During this utility model work, as thermistor R
fThe boiler water temperature of surveying does not reach the temperature of setting up as yet, and its resistance increases, triode BG
1Base potential reduces, and causes triode BG
1, BG
2Conducting, BG
2Collector voltage is less than below the 0.3V, this moment triode BG
3Base stage is an electronegative potential, makes it to end relay J
1No power.When boiler water temperature rises to the temperature of setting up, thermistor R
fResistance reduces, triode BG
1Base potential raises, (because BG
1Be the PNP pipe) triode BG
1End BG
2Base stage can not get operating current and also end triode BG
2Collector potential raises, and makes triode BG
3Saturation conduction, relay J coil electricity, normal opened contact J
1-1Water pump 3 working powers are connected in adhesive, force the interior water of boiler to circulate in pipeline.After circulating water temperature reduce to the temperature of setting up when following, thermistor R
fResistance increases again.Thereby cause triode BG
1, BG
2Conducting, BG
3End and the relay J coil blackout, circulation can realize the automatic circulation of boiler water and so forth.
