(5) specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Embodiment one
With reference to Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, a kind of gas fire, comprise base 1, on the described base 1 urceolus 2 is installed, be with heat insulation tube 3 in the described urceolus 2, the front end of described heat insulation tube 3 be provided with motor 4 and with the affixed fan blade 5 of output shaft of described motor 4, the rear end of described urceolus 2 is provided with out aerofoil, is provided with I-shaped gas valve 7 and ignition module in the described heat insulation tube 3.Described I-shaped gas valve 7 comprises inlet channel 8, outlet passageway 9, guides coal gas the transition passage 10 of outlet passageway into from inlet channel between inlet channel 8 and outlet passageway 9, and the place, gas outlet of described outlet passageway 9 is provided with air nozzle 6; Described ignition module comprises igniter 11, igniting pin 12 and combustion head 13.
In described gas valve 7, spiral shell is provided with regulating valve stem 14 in the described outlet passageway 9.On the flow direction of coal gas, be provided with step in the outlet passageway 9 in described transition passage 10 the place aheads, described step place forms a tapered channel, and the front end of described regulating valve stem 14 has conical head 15, and described conical head 15 is suitable with described tapered channel; Rear at transition passage 10, hermetic seal between described regulating valve stem 14 and described outlet passageway 9 inwalls, the place ahead at transition passage 10, have the space of giving vent to anger 16 between described regulating valve stem 14 and described outlet passageway 9 inwalls, the front end of described regulating valve stem 14 is provided with the venthole 17 that is communicated with the described space 16 of giving vent to anger.This structure has formed a gas output control valve of regulating the coal gas gas output, and this control valve also can be taked other forms, as the outlet valve of ball valve or water draw tap.
In order to prevent when flame-out, to produce the gas leakage accident; in the inlet channel 8 of gas valve, also be provided with the blowout protection magnetic valve; described blowout protection magnetic valve is electrically connected with a thermocouple 21; described thermocouple 21 is positioned at described heat insulation tube; described blowout protection magnetic valve not the described inlet channel of shutoff under the electric situation, described blowout protection magnetic valve also has a push rod 18 that is used for pushing open by force valve.
In order to prevent when cutting off the power supply, to produce the gas leakage accident, in the transition passage 10 of gas valve, be provided with power-off protection magnetic valve 19.
The utility model is when work; by gas inlet pipe joint 20 gas-jar and gas valve 7 are coupled together; connecting power supply simultaneously makes power-off protection magnetic valve 19 get electric opening; this moment is not because also not igniting also has gas-fired, thermocouple 21 low-temperature electricity-frees; the blowout protection magnetic valve not electric can't opening automatically; therefore must manually promote push rod 18, open the blowout protection magnetic valve by force, coal gas could be given vent to anger from outlet passageway 9 via transition passage 10 from inlet channel 8.Press igniter 11 igniting this moment; coal gas takes fire; thermocouple 21 generation of being heated; therefore the blowout protection magnetic valve gets electric can opening automatically; the thrust by force that need not to relend boosting bar 18 can keep the continuation open mode of blowout protection magnetic valve; the feeding of coal gas is continued, and burning is continued.The flow path of coal gas is: enter the space 16 of giving vent to anger between regulating valve stem and the outlet passageway inwall by inlet channel 8 through transition passages 10, enter outlet passageway 9 once more through the venthole 17 of regulating valve stem front end again and finally give vent to anger.
