Abstract
The utility model discloses a safety control device of a gas furnace, comprising a power supply, a main control panel 6 arranged in a control box, as well as a flame ionization probe 10 and a wind pressure switch 12 which are respectively connected with the main control panel 6, wherein the wind pressure switch 12 is connected with a gas inlet control valve 13 and controls the turning-on of the gas inlet control valve 13, and the flame ionization probe 10 detects whether flame exists or not. The utility model overcomes the defects of the prior art and is a safety control device of a gas furnace, which is safe, responses flexibly and can alarm and prompt.
Description
Technical field
The utility model relates to a kind of gas safety device, relates in particular to a kind of gas furnace safety control.
Background technology
Combustion gas is safe in utilization to be very important always, at present, the unlatching of the combustion gas air intake control valve door after the igniting is controlled by thermocouple, its principle is to pin igniter valve to light little fire in 3～4 seconds, make the flame heat thermocouple, thermocouple produces voltage and electric current after being heated to uniform temperature, control the combustion gas air intake control valve then and open, light big fire, if burner is flame-out midway, thermocouple needs 20～40 second time to reduce temperature, not output voltage and electric current after 20～40 seconds, the combustion gas air intake control valve is closed, in 20～40 second time, burner can leak a large amount of combustion gas, the combustion gas meeting of leaking when lighting a fire once more causes detonation, or even blast, leads to a disaster, whether igniting is successful in addition, fault is flame-out does not midway all have obviously indication to report to the police, and operating personnel were handled in the shortest time.
The utility model content
But the technical problems to be solved in the utility model provide a kind of overcome above defective, safely, the gas furnace safety control of the alarm that is quick on the draw.
The utility model solves above-mentioned technical problem by the following technical programs: a kind of gas furnace safety control, comprise power supply, be arranged on the master control borad in the control box, flame ion detector and the blast switch that is connected with master control borad respectively, wherein blast switch is connected with the combustion gas air intake control valve, the unlatching of blast switch control combustion gas air intake control valve, whether described flame ion detector detects burner has flame to exist.
Also be connected with flame-out alarm mechanism on the master control borad.
Described flame-out alarm mechanism comprises the warning circuit that is connected with master control borad, is connected with loudspeaker in the warning circuit, and loudspeaker is fixed in the control box.
Described flame ion detector comprises and is arranged on furnace head burner top as the flame ion probe of electric field positive pole, as the burner of electric field negative pole.
The control box panel is provided with ignition light, power supply indicator, operate as normal indicator lamp, and master control borad is connected with ignition light, power supply indicator, operate as normal indicator lamp respectively.
The utility model adopts the flame ion detector to monitor igniting and stove and accessory combustion process, the flame ion detector can detect in 1 second whether flame is arranged, directly signal is transferred to master control borad, master control borad sends instruction at signal, opens or close the combustion gas air intake control valve, and whole actuation time is in 1～3 second, time is short, be quick on the draw, can not cause combustion gas to leak in a large number, safe and reliable; Moreover the whole ignition process and the stove and accessory course of work all are in the monitor state of flame ion detector, in case occur unusual, master control borad sends instruction, closes the combustion gas air intake control valve, and corresponding ignition light, operate as normal indicator lamp knock out, and flame-out alarm mechanism sends warning, remind the operator in time to handle, in addition, adopt blast switch control combustion gas air intake control valve, when not having air intake, no matter whether light a fire, can not open the combustion gas air intake control valve, guarantee the stove and accessory handling safety.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples, in the accompanying drawing:
Fig. 1 is the connection block diagram of the utility model embodiment;
Fig. 2 is the structural representation of the utility model control box.
The specific embodiment
As Fig. 1, shown in 2, an embodiment of the utility model gas furnace safety control comprises power supply 7, be arranged on the master control borad 6 in the control box 1, flame ion detector 10 that is connected with master control borad 6 and blast switch 12 respectively, wherein blast switch 12 is connected with combustion gas air intake control valve 13, the unlatching of blast switch 12 control combustion gas air intake control valves 13, whether burner is surveyed in described flame ion detector inspection 10 has flame to exist, described flame ion detector 10 comprises that being arranged on furnace head burner 9 tops pops one's head in 8 as the flame ion of electric field positive pole, burner 9 as the electric field negative pole, control box 1 panel is provided with ignition light 4, power supply indicator 3, operate as normal indicator lamp 5, master control borad 6 respectively with ignition light 4, power supply indicator 3, operate as normal indicator lamp 5 connects, also be connected with flame-out alarm mechanism 11 on the master control borad 6, described flame-out alarm mechanism 11 comprises the warning circuit that is connected with master control borad 6, be connected with loudspeaker 2 in the warning circuit, loudspeaker 2 is fixed in the control box 1.
The course of work: when power-on 7, power supply indicator 3 lights, continue the ignition switch of press points firearm, pulse firing, light flame, flame top produces cation, flame base produces anion, negative ions produces electric field and forms gas current, during the gas current of several microamperes that form when the required flames of flame ion detector sense 10～1 milliampere, can conclude that igniter lights flame, flame ion detector 10 is transferred to master control borad 6 with signal, when blower fan is worked, distinguished and admirable mistake is arranged in the air channel of blast switch 12, the blast effect drives the normally opened contact closure of blast switch 12, master control borad 6 is opened combustion gas air intake control valve 13 by blast switch 12, and combustion gas sprays from burner 9 fire holes, meets fire and lights, at this moment, ignition light 4, operate as normal lamp 5 lights, if after 3 seconds of lighting a fire, flame ion detector 10 is not sensed the flame of lighting, ignition light 4 extinguishes and master control borad 6 control alarm mechanisms 11 are reported to the police, the expression loss of ignition, after abandoning pushing ignition switch, alarm mechanism 11 is closed, if need igniting again, can push ignition switch once more; When the stove and accessory operate as normal is flame-out midway, 10 inductions of flame ion detector are less than flame, combustion gas air intake control valve 13 is cut off in master control borad 6 controls in 1 second, operate as normal indicator lamp 5 extinguishes, master control borad 6 control alarm mechanisms 11 are reported to the police simultaneously, close until power supply 7, igniting again then needs again power-on 7 and carries out ignition procedure if desired.
