Technical field
The utility model relates to the technical field of tappasaki equipment, specifically a kind of automatic ignition flame-out protection device for combustion type tappasaki equipment, particularly its mechanical connecting structure.
Background technology
Tappasaki equipment, uses natural gas, liquefied gas or gas-fired conventionally, thereby produce heat energy, iron plate is heated.Because stove and accessory is arranged on device interior, light a fire not too convenient.In fuel gas buring process, can, because the faults such as under-voltage, anoxic are extinguished burning, if can not find in time, will directly discharge without natural gas, liquefied gas or the coal gas of burning unavoidably, exist the potential safety hazard of anthracemia or blast.
Do not find at present and explanation or the report of the similar correlation technique of the utility model, not yet collect both at home and abroad similarly data yet.
Summary of the invention
The purpose of this utility model is to provide a kind of automatic ignition flame-out protection device for combustion type tappasaki equipment, in gas heating tappasaki equipment, is provided with automatic ignition, flame-out protection safety device.Automatic ignition, flame-out protection safety device energy automatic ignition, and can automatically cut off fuel gas source after the fire of stove and accessory extinguishes, avoid the leakage of combustion gas, thereby guaranteed safety, overcome the shortcoming and defect existing in prior art.
To achieve these goals, the technical solution of the utility model is: a kind of automatic ignition flame-out protection device for combustion type tappasaki equipment, it comprises fuel gas source, it is characterized in that: described fuel gas source is connected with the combustion gas input of valve body by the first Gas Pipe, the combustion gas output of valve body is connected with ignition frame by the second Gas Pipe, this ignition frame is arranged at stove and accessory place, valve body place is provided with knob, knob is connected with microswitch, this microswitch is connected with the control input end of step-up transformer by electric wire, the control output end of step-up transformer is connected with ignition electrode by wire, ignition electrode is positioned at ignition frame one side, the burner place of ignition frame opposite side is provided with thermocouple, this thermocouple is connected with the magnetic valve input control end in valve body by wire, the main combustion gas output of valve body is connected with the combustion gas input of stove and accessory by combustion gas main channel, the switching of combustion gas main channel port in above-mentioned solenoid control valve body.
The utility model discloses a kind of electric spark that automatically presses electric discharge for combustion type tappasaki equipment and give me a little the device of the fuel gas of burner tool.Blowout protection mode is fiery flame-out protection device, and gas heating tappasaki automatic ignition is electric pulse igniting, is to utilize high thermojunction type; its operation principle is that thermocouple is while being heated; it can produce thermoelectrical potential, and this electromotive force can make electromagnetic valve work, thereby controls the switching of blast tube.Protective device has effectively promoted the safety coefficient of tappasaki equipment, has good practicality.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
The specific embodiment
With reference to the accompanying drawings, the utility model is further described.
Wherein:
1, fuel gas source;
2, knob;
3, microswitch;
4, valve body
5, step-up transformer
6, burner;
7, ignition electrode;
8, ignition frame;
9, thermocouple;
10, the first Gas Pipe;
11, the second Gas Pipe;
12, combustion gas main channel.
The utility model is a kind of automatic ignition flame-out protection device for combustion type tappasaki equipment, it comprises fuel gas source 1, it is different from prior art and is: described fuel gas source 1 is connected with the combustion gas input of valve body 4 by the first Gas Pipe 10, the combustion gas output of valve body 4 is connected with ignition frame 8 by the second Gas Pipe 11, this ignition frame 8 is arranged at stove and accessory 6 places, valve body 4 places are provided with knob 2, knob 2 is connected with microswitch 3, this microswitch 3 is connected with the control input end of step-up transformer 5 by electric wire, the control output end of step-up transformer 5 is connected with ignition electrode 7 by wire, ignition electrode 7 is positioned at ignition frame 8 one sides, burner 6 places of ignition frame 8 opposite sides are provided with thermocouple 9, this thermocouple 9 is connected with the magnetic valve input control end in valve body 4 by wire, the main combustion gas output of valve body 4 is connected with the combustion gas input of stove and accessory 6 by combustion gas main channel 12, the switching of the interior combustion gas of above-mentioned solenoid control valve body 4 main channel 12 ports.
When concrete enforcement, in the situation that guaranteeing fuel gas source normal supply, knob is advanced, open microswitch, make step-up transformer work by electric wire, the conduction of admittance line makes ignition electrode pulse igniting again, again knob is rotated counterclockwise to approximately 15 degree, the seedling fire passage of valve body is opened, by gas pipeline, combustion gas is transported to ignition frame, lighted by ignition electrode, burning fire makes the thermocouple generation thermoelectrical potential of being heated, thermoelectrical potential imports the magnetic valve in valve body by wire, thereby the combustion gas main channel of valve body is opened, by combustion gas main channel, combustion gas is transported to stove and accessory, lighted by ignition frame, and maintain its normal combustion, once run into under-voltage, the reasons such as anoxic make fray-out of flame, the thermoelectrical potential of thermocouple drops to zero very soon, magnetic valve in valve body lost efficacy, under spring action, reset rapidly, valve body is closed blast tube, stop air feed, guarantee safety.
Above content is in conjunction with concrete preferred embodiment further detailed description of the utility model, can not assert that the concrete enforcement of the utility model is confined to above-mentioned these explanations.For the utility model person of an ordinary skill in the technical field, without departing from the concept of the premise utility, can also make some simple deduction or replace, all should be considered as belonging to protection domain of the present utility model.
