The specific embodiment
Below in conjunction with the specific embodiment, further set forth the utility model:
As Fig. 1, Fig. 2 and shown in Figure 3; a kind of dual-gas source combustion device of the utility model; it comprises pressure-reducing valve 1, control valve 9, burner and safety guard ODS2; also comprise a gas kind selector valve 7; this gas kind selector valve comprises at least one air inlet and at least two gas outlets; when it was imported according to gas with various, the admission pressure difference of gas with various was selected gas port automatically.The patent that this gas kind selector valve concrete structure can be our company's application gas kind selecting arrangement (is respectively as application number: 201010174667.5; 201020158512.8; 201020158511.3) described in arbitrary structure, be not limited thereto, as long as can select corresponding gas outlets automatically, realize that the function of selecting automatically just can according to different its admission pressures of input gas are different.The gas outlet of this gas kind selector valve 7 is corresponding continuous with the air inlet of pressure-reducing valve 1 respectively, and the gas outlet of pressure-reducing valve 1 links to each other with control valve 9; The output of control valve 9 divides two-way, one tunnel input safety guard ODS2, another road input burner.Said burner comprises a mixing tube 6, igniter 8, gas adaptive nozzle 4, the output of control valve 9 links to each other with gas adaptive nozzle 4, gas adaptive nozzle 4 output termination mixing tubes 6 inputs, damper 5 places the input of mixing tube 6, igniter 8 places the contiguous place of mixing tube 6 outputs, and the patent that these gas kind adaptive nozzle 4 concrete structures can be the gas kind automatic nozzle of our company's application (is respectively as application number: 201020178998.1; 201010161402.1; 201010161369.2) described in arbitrary structure, be not limited thereto, automatically select corresponding gas outlet just can as long as can realize the gas kind.
This safety guard ODS2 mainly comprises thermocouple 101, igniter head 102, gas adaptive nozzle 103; this gas adaptive nozzle 103 concrete structures such as Fig. 4 and shown in Figure 5; it comprises 1 or 2 shower nozzles and two kinds of automatic selector channels of gas kind; if shower nozzle is two and then distinguishes the automatic selector channel of corresponding a kind of gas kind, if shower nozzle is then two kinds of shared these shower nozzles in the automatic selector channel of gas kind.This bottom, automatic selector channel of gas kind is provided with a sprue and is set in spring on this sprue, and the spring force difference in two passages, when input gas different variations taking place, and then make the passage closure or openness, makes gas flow through corresponding passage and reach the purpose that gas is selected automatically.
Device of the present utility model be as shown in Figure 1 Emulational wood warmer (GAS LOG), gas heating stove as shown in Figure 2 (STOVE) or as the fireplace (FIREPLACE) of Fig. 3.
Operation principle of the present utility model is: insert natural gas or liquefied gas, also pressing igniter 8 simultaneously carries out constant ignition to press control valve 9 igniting valves, combustion gas enters gas kind selector valve 7, because the admission pressure of natural gas and liquefied gas differs greatly, gas kind selector valve 7 is selected the path of gas to enter in the pressure-reducing valve 1 according to the size of pressure to reduce pressure, part enters ODS gas kind selector valve 1 through the combustion gas of decompression by control valve 9, this moment, ODS gas kind selector valve 1 was selected corresponding outlet pipe according to the size of gas pressure, combustion gas is under certain pressure, flow out with certain flow velocity, the ejector action that relies on combustion gas kinetic energy to produce, suck primary air from the air inlet of ODS nozzle 2 induction tunnels, and in induction tunnel, mix, mist flows out through the head of ODS nozzle 2.At this moment, the high tension spark that meets igniter 8 generations just produces burning, burning produces thermoelectrical potential and passes to control valve 9 by the thermocouple on the ODS nozzle 2 and the main gas circuit of control valve 9 is opened, knob on the adjusting control valve 9 is regulated the combustion gas air inflow at this moment, combustion gas is by burner nozzle 4, burner nozzle 4 is selected corresponding venthole according to the size of gas pressure, and the ejector action of dependence combustion gas kinetic energy generation is from the inlet end suction primary air of mixing tube 6, what of mixed once air are the air inflow of damper 5 regulate, combustion gas with flow to burner 3 after air mixes in mixing tube 6, from the fire hole of burner 3, flow out the flare that runs into ODS2 and promptly produce burning, when accident extinguishing, the thermoelectrical potential that thermocouple on the 0DS2 produces weakens, and control valve 9 is closed, and guarantees security thereby cut off main gas circuit.
But the above-mentioned specific embodiment is exemplary, is to be the restriction that this patent is comprised scope in order better to make those skilled in the art can understand this patent, can not to be interpreted as; So long as according to spirit that this patent discloses done anyly be equal to change or modify, all fall into the scope that this patent comprises.
