Further; described boiler safety protection device also comprises control unit; described control unit connects described overpressure protection switch, boiler circuit and burner power supply, and when described overpressure protection switch sends induced signal, control unit controls boiler circuit and burner power cut-off.
Further, described boiler circuit and burner power supply are equipped with switch series circuit, described control unit is electrically connected described switch series circuit.
Further, described control unit is PLC or singlechip controller.
Further, described boiler circuit is also connected with the 3rd relay, described 3rd relay is connected with overtemperature prote switch to control the break-make of boiler circuit.
Further, described overtemperature prote switch is electrically connected described control unit, and when described overtemperature prote switch sends induced signal, control unit can control boiler circuit and burner power cut-off.
The beneficial effects of the utility model:
Boiler safety protection device of the present utility model, when the overtension of boiler, overpressure protection switch is triggered, and overpressure protection switch control rule first relay disconnects and makes boiler circuit breaker, stops the operation of boiler.Further, boiler safety protection device also comprises the second relay and burner power supply, makes the also power-off of burner power supply while boiler down circuitry by the second relay; after guaranteeing boiler down; combustor also quits work, and prevents overtension in boiler, ensures the safety run.
These features of the present utility model and advantage will detailed description of the invention below, exposure detailed in accompanying drawing.
[accompanying drawing explanation]
Below in conjunction with accompanying drawing, the utility model is described further:
Fig. 1 is principle schematic of the present utility model;
Fig. 2 is control schematic diagram of the present utility model.
[detailed description of the invention]
The technical scheme of accompanying drawing to the utility model embodiment below in conjunction with the utility model embodiment is explained and illustrated, but following embodiment is only preferred embodiment of the present utility model, and not all.Based on the embodiment in embodiment, those skilled in the art under the prerequisite not making creative work obtain other embodiment, all belong to protection domain of the present utility model.
With reference to figure 1; shown a kind of boiler safety protection device; comprise boiler circuit 3, first relay 2 and overpressure protection switch 1; boiler circuit 3 and the first relay 2 are connected; overpressure protection switch 1 is connected with the first relay 2 break-make controlling boiler circuit 3, and when the overtension of boiler, overpressure protection switch 1 is triggered; overpressure protection switch 1 controls the first relay 2 makes boiler circuit 3 disconnect, and stops the operation of boiler.Further, boiler safety protection device also comprises the second relay 4 and burner power supply 5, second relay 4 and burner power supply 5 and connects, and boiler circuit 3 connects the second relay 4 with the break-make of control combustion installation's power source 5.Boiler circuit 3 power-off makes burner power supply 5 also power-off by the second relay 4, and after guaranteeing boiler down, combustor also quits work, and prevents temperature too high.
With reference to figure 1 and Fig. 2; and; boiler safety protection device also comprises control unit 8; control unit 8 connects overpressure protection switch 1, boiler circuit 3 and burner power supply 5; when overtension triggers overpressure protection switch 1; overpressure protection switch 1 sends induced signal to control unit 8, and control unit 8 can control boiler circuit 3 and burner power supply 5 power-off.Therefore the power-off of equipment controls to be divided into two-way; one tunnel Access Control unit 8 is used for showing fault and shutdown; in another road place in circuit; be so just that control unit 8 controls inefficacy or malfunctioning; an other road mechanical protection also can the power supply of off device; can not make the bursting of boilers, double protection, security is good.
Concrete, boiler circuit 3 and burner power supply 5 are provided with switch series circuit, and control unit 8 is electrically connected switch series circuit, and control unit 8 gauge tap series circuit disconnects and makes boiler circuit 3 and burner power supply 5 power-off.
The control unit 8 adopted can be PLC or singlechip controller.
Further; boiler circuit 3 is also connected with on the 3rd relay the 7, three relay 7 and is connected with overtemperature prote switch 6 to control the break-make of boiler circuit 3, overtemperature prote switch 6 triggers the power-off of rear control the 3rd relay 7; 3rd relay 7 makes boiler circuit 3 power-off, stops the operation of boiler.After boiler circuit 3 power-off, the second relay 4 disconnects and makes burner also power-off, with when temperature is too high, boiler and combustor is shut down.
Further, overtemperature prote switch 6 is electrically connected control unit 8.When overpressure protection switch 1 sends induced signal, control unit 8 can control boiler circuit 3 and burner power supply 5 power-off too by the mode of electronics, improves security.
By above-described embodiment, the purpose of this utility model is reached by fully effective.The personage being familiar with this technology should be understood that the content that the utility model includes but not limited to accompanying drawing and describes in detailed description of the invention above.Any amendment not departing from function and structure principle of the present utility model all will comprise within the scope of the appended claims.
