2. a kind of fuel gas heating apparatus of the present utility model, simple in structure because of adopting automatons such as magnetic valve, temperature control valve, except that blower fan, need not realize safety guarantee by external power source.

Description of drawings

Below in conjunction with accompanying drawing the utility model is adopted a kind of fuel gas heating apparatus of the present utility model, embodiment is elaborated.Described embodiment is that the mode with non-limiting example provides:

Fig. 1 is the vertical cut-away view of a kind of fuel gas heating apparatus structure of the utility model;

Fig. 2 is for adopting the burner structure schematic diagram of a kind of fuel gas heating apparatus of the utility model.

Marginal data: 1---burner 2---igniting pin 3----ignition tube 4----thermocouple 5---bronchus 6----temp probe 7---master tracheae 8---master control valve 9----temperature control valve 10----magnetic valve 11----plug valve 12----piezoelectrics 13----combustion gas 14----combustion chamber 15---blower fan 16----cabinet shell 17---air 18---heated air flow circulation passage 19---gas emission passage

The specific embodiment

With reference to Fig. 1 is the vertical cut-away view of a kind of fuel gas heating apparatus structure of the utility model, comprise combustion chamber 14 and gas emission passage 19, blower fan 15 and heated air flow circulation passage 18 thereof that cabinet shell 16, burner 1, Heat Conduction Material are made, described burner 1 and blower fan 15 are arranged on lower box and lay respectively in combustion chamber 14, the heated air flow circulation passage 18, gas emission passage 19 and heated air flow circulation passage 18 separate, tight adjacent being set up in parallel, gas emission passage 19 top vertical sectional shapes are hollow H shape.

Burner 1 is lighted combustion gas heating flame chambers 13 14 walls and surrounding air during work, heat flows along gas emission passage 19 and transmits, simultaneously air 17 is forced to flow and absorb gas emission passage 19 wall heats rapidly and heat up along heated air flow circulation passage 18 through blower fan 15, sends into space specified again.

For adopting the burner structure cut-away view of a kind of fuel gas heating apparatus of the utility model, described burner 1 control device is better controlled combustion gas size and then control room temperature for plug valve 11 to be set on fuel gas transportation pipeline with reference to Fig. 2.At described burner 1 control device is that magnetic valve 10 and temperature control valve 9 are set behind the plug valve on the fuel gas transportation pipeline 11, insert bronchus 5 on the main tracheae 7 between them, be introduced near the igniting pin 2, strengthen the safety measure of fuel gas heating apparatus, plug valve 11, temperature control valve 9, magnetic valve 10 are integrated form master control valve body 8.

During use, depress plug valve handle 11, pin piezoelectrics 12 simultaneously.Machinery is opened magnetic valve 10 when depressing handle.Combustion gas 13 this moment is discharged under piezoelectrics 12 effects by bronchus 5 arrival ignition tubes 3 igniting pins 2 ignition tube 3 is lighted.The flame that ignition tube 3 is lighted is burning thermocouple 4, and the electric current that thermocouple 4 produces makes magnetic valve 10 enter duty and keeps ignition tube 3 sustained combustions.

Be rotated counterclockwise handle plug valve 11 main gas are opened, reach ignition tube 3 burned flames burner 1 is lighted, this moment, fuel gas heating apparatus entered duty (heating).

When accident extinguishing, there is not flame burning thermocouple 4, thermocouple 4 does not produce electric current, and magnetic valve 10 loses electric current and cuts out.Thereby cut off the purpose that all right gas passages reach safe handling.Continue to use the operation that repeats the front to get final product.

When room temperature was too high, temp probe 6 sense temperature surpassed set temperature value, and closing temperature control valve 9 cuts off main tracheae 7 and makes burner 1 no combustion gas and fray-out of flame automatically, and ignition tube 3 (ever-burning flame) burns away.Stop heat supply this moment.Indoor temperature is reduced to when setting low temperature, and temperature control valve 9 is opened automatically, and burner 1 is air feed again, and burner 1 is ignited by ignition tube 4 (ever-burning flame) and recovers heating.Can automatically indoor temperature be controlled in the design temperature scope.

Turn clockwise handle to abut, close this warmer, this warmer is stopped using.

Certainly, the invention is not restricted to address the embodiment shown in the accompanying drawing, modification and equivalent transformation that the spirit of Fan Yiben creation is done, or adopt various deformation on this basis, all belong in the protection domain of the present invention.
