The specific embodiment
Below in conjunction with the specific embodiment, further set forth the present invention:
Shown in Fig. 1-6, a kind of dual-gas source ignition device with oxygen depletion safety device of the present invention, it comprises an installing rack 1, and be installed in thermocouple 2 and igniter head 3 on the installing rack 1, comprise that also a gas that is fixed on the installing rack 1 selects nozzle 4 automatically, this gas selects the gas outlet of nozzle 4 to place thermocouple 2 and igniter head 3 contiguous places automatically, and this vicinity is sentenced when burning flame and can be touched thermocouple and be as the criterion; This gas selects nozzle to be provided with an air inlet and two kinds of gas passages automatically, and nearly air inlet place, two kinds of gas passage bottoms establishes a sprue 5 respectively and is set in the elastic force difference of 6, the two kinds of gas passage inner springs 6 of spring on this sprue.Below sprue 5, pressure regulation bolt 7 can also be set, make spring be in suitable elastic stage, when input gas, can change its elasticity and reach the purpose that promotes the sprue motion by regulating this pressure regulation bolt.And its inner space, the upper end of two kinds of gas passages is diminishing cavity, and be provided with filter screen 8 in the middle part, the impurity of this filter screen 8 in can elimination gas, and establish a jewel 9 at the top of upper end, this jewel 9 has a less jewel hole and sprays as gas nozzle.
The first embodiment of the present invention as shown in Figures 1 and 2, this dual gas-supply oxygen-poor igniter are except said structure, and its gas selects nozzle 4 to be provided with 1 gas outlet automatically, shared this gas outlet of above-mentioned two kinds of gas passages, and this gas outlet is towards thermocouple 2.
The second embodiment of the present invention as shown in Figures 3 and 4, this dual gas-supply oxygen-poor igniter is except above-mentioned common structure, its gas selects nozzle 4 to be provided with 2 gas outlets automatically, the respectively corresponding gas outlet of above-mentioned two kinds of gas passages, and this gas outlet and corresponding gas passage 4 angled settings, make the gas outlet respectively towards thermocouple 2, thermocouple 2 is placed between two gas outlets, above-mentioned igniter head 3 is one or two, if one just places between two gas outlets, if two can be distinguished corresponding gas outlet.
As the Fig. 5 and the third embodiment of the present invention shown in Figure 6, this dual gas-supply oxygen-poor igniter except above-mentioned common structure is, its gas selects nozzle 4 to be provided with 2 gas outlets automatically, the respectively corresponding gas outlet of above-mentioned two kinds of gas passages, and this gas outlet and corresponding gas passage 4 vertical settings, above-mentioned igniter head 3 is two, respectively corresponding gas outlet.A fuse primer 10 is established and towards above-mentioned thermocouple 2 in this outside, gas outlet, flame guiding thermocouple.
Above-mentioned gas selects nozzle 4 to establish a loam cake 11 that comprises air admission hole automatically, selects gas nozzle 4 to be fixed on the installing rack 1 automatically by this loam cake 11.And the joint between this nozzle interior cavity all is provided with sealing gasket as sealing.
Operation principle of the present invention is: when air inlet inserted natural gas, gas entered from the hole of pressure regulation bolt 7, and one of them gas passage is made as the natural gas passage, promptly the strength of its contained spring a little less than; And that the another one gas passage is made as its contained spring strength of liquefied gas passage is strong and be in compressive state, the natural gas spring stress begins to take place deformation, gas promotes the natural gas sprue, and enter above-mentioned passage by the gap between natural gas sprue and the pressure regulation bolt, because gas pressure is lower, the elastic force strength of liquefied gas spring is greater than gas pressure, so natural gas can not promote the liquefied gas sprue, can't admission passage, natural gas flows to nozzle again, and through filter screen, the jewel orifice flow goes out, rely on the ejector action of gas, suck air and mix from the air admission hole of loam cake 11, run into the high tension spark that igniter head 3 gets and light gas, flame is by fuse primer 10 guiding thermocouples 2, when accident extinguishing, the thermoelectrical potential that thermocouple 2 produces disappears.
When air inlet inserts liquefied gas, gas enters from the hole of pressure regulation bolt 7, the strength of natural gas spring a little less than, because gas pressure is bigger, promote the natural gas sprue and block the gas outlet, so gas can't enter the natural gas nozzle, this moment, the liquefied gas spring was subjected to gas pressure effect generation moderate finite deformation, gas enters the outlet side of valve body by the gap between liquefied gas sprue and the pressure regulation bolt, liquefied gas flows to nozzle again, and through filter screen, the jewel orifice flow goes out, rely on the ejector action of gas, suck air and mix from the air admission hole of loam cake 11, run into the high tension spark that igniter head 3 gets and light gas, flame is by fuse primer 10 guiding thermocouples 2, when accident extinguishing, the thermoelectrical potential that thermocouple produces disappears.
Another kind of dual-gas source ignition device with oxygen depletion safety device of the present invention as shown in Figures 7 and 8, it comprises an installing rack 1, and be installed in thermocouple 2 and igniter head 3 on the installing rack 1, comprise that also one is fixed on two gases on the installing rack 1 and selects 4, two gases of nozzle to select the gas outlet of nozzle 4 to place thermocouple 2 and igniter head 3 contiguous places respectively automatically automatically; Gas is selected nozzle 4 bottoms to establish a sprue 5 automatically and is set in the elastic force difference that 6, two gases of spring on this sprue 5 are selected the nozzle inner spring automatically.Gas selects nozzle 4 also to comprise an inwardly projecting orifice 12 automatically, and this inwardly projecting orifice 12 is fixed on sprue 5 tops by bracing frame and rotary moveable is selected nozzle inner walls automatically in gas.Be provided with a filter screen 8 in the inwardly projecting orifice 12, and be provided with jewel hole 9 on the top of this inwardly projecting orifice 12.Can arrive suitable elastic stage by regulating spring by the inwardly projecting orifice of regulating in this device.
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.
