Detailed description of the invention
Below in conjunction with accompanying drawing embodiment, the utility model is described further:
As shown in Figure 1, 2, this gas generator comprises two gas inlet dispensing devices, combustion tube 7 and ever-burning flame generating means 14.
Gas inlet dispensing device comprises nozzle 1, self-straw 3, adjustable ventilation door 2, mixing tube 4, diffuser pipe 5 and distributor box 6.Self-straw 3 comprises reducer and isometrical section, reducer by forward direction after diameter reduce successively, the equal diameters of the diameter of isometrical section and reducer end.Nozzle 1 is positioned at the front end of self-straw 3, and aligns with self-straw 3 is concentric.The rear end of self-straw 3 connects with mixing tube 4, and connecting mode is for being threaded.As shown in Figure 3, adjustable ventilation door 2 is set in self-straw 3, the rear end of adjustable ventilation door 2 can be inserted into the position in self-straw 3 in mixing tube 4 and by the fixing adjustable ventilation door 2 of set screw 9 on mixing tube 4.Between adjustable ventilation door 2 and self-straw 3, form interlayer, air enters in interlayer under the drive of combustion gas.Mixing tube 4 is fixed to the below of combustion tube 7 by fixed mount 8.
Unscrew after set screw 9, adjustable ventilation door 2 can move in self-straw 3, the size of air air inflow when the position according to adjustable ventilation door 2 front ends in self-straw 3 regulates self-priming.The more forward end of adjustable ventilation door 2, air inflow is less.After air intake in mixing tube 4 with combustion gas mixing, the uniformity of mixing in order to improve combustion gas and air, sets up diffuser pipe 5 in the rear end of mixing tube 4.The caliber of diffuser pipe 5 becomes large after by forward direction gradually, can make combustion gas and air mix and carry in next parts with identical flow velocity.The rear end of diffuser pipe 5 connects with the entrance of distributor box 6, and the outlet of distributor box 6 connects with combustion tube 7.Mixing tube 4, diffuser pipe 5 and distributor box 6 form air delivering pipeline.On each distributor box 6, respectively offer three outlets, correspondingly be that three combustion tubes 7 are coupled.The other end of combustion tube 7 is fixing by turning fire cover plate 11.
In order to increase heating surface (area) (HS, the quantity of gas inlet dispensing device is two, and the nozzle 1 of two gas inlet dispensing devices all connects with the two ends of distributing pipe 12, and the middle part of distributing pipe 12 connects air inlet pipe joint 13.Air inlet pipe joint 13 connects with main combustible pipe road.Ever-burning flame generating means 14 is positioned at combustion tube 7 5cm places, top, for pilot combustion pipe 7 mist out.Ever-burning flame generating means 14 comprises kindling material head 14.1 and support 14.2, and kindling material head 14.1 is fixed on support 14.2 upper brackets 14.2 and is fixed on rack plate 10.Rack plate 10 is positioned at the top of nozzle 1, prevents that the interface of the fine particle thing plug nozzle 1. kindling material heads 14.1 such as dust is connected with time fuel gas pipeline.
The utility model operation principle and the course of work are as follows:
Rise when kitchen range, first open the valve Shi Gai road of time fuel gas pipeline and connect, then press fire maker and make the kindling material head 14.1 generation flame that ignites.The valve of now opening again main combustible pipe road starts to supply gas.Combustion gas distributing pipe 12 be divided into two-way again two nozzles 1 spray, the combustion gas of ejection has certain flow velocity to be injected to the front end of self-straw 3, and ambient air is introduced in the interlayer between adjustable ventilation door 2 and self-straw 3 under himself flow velocity drives.Then combustion gas is met and tentatively mixes with the air of introducing in mixing tube 4, then continues to next part mobile.In diffuser pipe 5, thereby due to becoming gradually of diameter cause greatly volume to increase gradually making the flow velocity of mist more synchronous, mix also more even, then enter into distributor box 6, through the shunting action of distributor box 6, mist enters respectively in three combustion tubes 7.Produce because kindling material head 14.1 has had flame, the gaseous mixture that therefore combustion tube 7 ejects is known from experience rapid burning under the igniting of flame, uses for culinary art.After culinary art, first turn off the valve on main combustible pipe road, after flame knocks out, according to circumstances determine whether to close again the valve of time fuel gas pipeline.Need to continue the sustained combustion that just makes kindling material head 14.1 of culinary art, do not need to continue the valve that just can close time fuel gas pipeline of culinary art.
The above, it is only preferred embodiment of the present utility model, be not the restriction of the utility model being made to other form, any those skilled in the art may utilize the technology contents of above-mentioned announcement to be changed or be modified as the equivalent embodiment of equivalent variations.But every technical solutions of the utility model content that do not depart from, any simple modification, equivalent variations and the remodeling above embodiment done according to technical spirit of the present utility model, still belong to the protection domain of technical solutions of the utility model.
