Description
Technical field
The utility model relates to burner for gas stove field, particularly a kind of air ejection adjustment structure.
Background technology
The theory of combustion of household gas range is, by the drive of high-speed fuel gas, injection partial air is incorporated into injector inside, reaches the effect of mixing in injector, finally sprays at burner head and burns.
Existing air ejection governor motion comprises injector, mixing tube, air-breathing collapsible tube and nozzle, nozzle ejects high-speed fuel gas, under combustion gas drives, bring air into from air-breathing collapsible tube inlet portion, and complete the preliminary mixing of air and combustion gas at air-breathing collapsible tube, enter injector mixing after again mixing by mixing tube, reach the balance of air and combustion gas mixed gas concentration field.
Due to the diversity of source of the gas, injection governor motion needs to be suitable for different sources of the gas, as liquefied petroleum gas, natural gas and manufactured gas, manufactured fuel gas etc.Because the constituent of often kind of source of the gas is different, air capacity required in their combustion processes is also different.If the air capacity required for the air ratio of effective supply is little, burning can be caused insufficient, and discharge amount of exhaust gas is high, or even occurs unburnt phenomenon, as yellow flame.If the air capacity required for the air ratio of effective supply is large, then can bring impact to combustion stability, as there is tempering, from flame, de-fire waits burning bad phenomenon.So for different types of source of the gas, the design of injection governor motion just needs certain adaptation width and controllability.
In actual use, the method that head it off uses mainly contains: regulated by the area of air-breathing collapsible tube entrance, the miscellaneous parts such as induction tunnel are all constant, its advantage is the injection volume that can regulate primary air, shortcoming is because the miscellaneous parts such as induction tunnel are constant, and gas and vapor permeation effect does not change substantially.A kind of mode is also had to be regulate nozzle to the distance of mixing tube, its advantage changes mixing tube length by equivalence to change mixed effect, simultaneously the injection volume of primary air can change to some extent due to the variation of nozzle to the distance of mixing tube, shortcoming is owing to lacking air-breathing collapsible tube, the surplus of the air capacity of institute's injection is few, adapts to width inadequate.
Utility model content
The purpose of this utility model is to overcome above-mentioned deficiency existing in prior art, a kind of air ejection adjustment structure is provided, make adjustable the changing of the air capacity of burner for gas stove injection adapt to different source of the gas, make the air after injection and combustion gas mixing effect have large lifting and change thus make final fuel gas buring abundant simultaneously.
In order to realize foregoing invention object, the technical solution adopted in the utility model is: a kind of air ejection adjustment structure, comprise the injector be connected with burner head, the afterbody of described injector connects mixing tube, the afterbody of described mixing tube connects the air-breathing collapsible tube for making air enter described mixing tube, it is characterized in that, described injector is also provided with holder, described holder is provided with the nozzle for making combustion gas enter described mixing tube, described holder is also provided with position-limit mechanism, described air-breathing collapsible tube has position adjusting mechanism, described position adjusting mechanism is the mobile distance regulated between described air-breathing collapsible tube and described nozzle on described position-limit mechanism.
Preferably, described position-limit mechanism is for being arranged on the monosymmetric depressed part of described holder.
Preferably, described position adjusting mechanism is the guide rail being connected to described air-breathing collapsible tube both sides.This guide rail moves in described depressed part, can regulate the distance between air-breathing collapsible tube and described nozzle by guide rail, simple and convenient easy to operate.
Preferably, described mixing tube is together with the fixed seal connection of air-breathing collapsible tube, and the head of described mixing tube inserts the afterbody of described injector.
Described air-breathing collapsible tube is cross section is square air-breathing collapsible tube.Such air intlet area is large, and the ejector capacity of air ejection adjustment structure primary air is strong.
compared with prior art, the beneficial effects of the utility model:
This practical air ejection adjustment structure arranges holder on injector, holder is provided with position-limit mechanism, setting position governor motion on air-breathing collapsible tube, position adjusting mechanism is the mobile distance regulated between described air-breathing collapsible tube and described nozzle on described position-limit mechanism, air-breathing collapsible tube is made to move forward and backward like this, and move in certain scope, required air capacity and mixability can be regulated by the movable of air-breathing collapsible tube, meet the requirement of the different air capacity of different source of the gas needs.Air simultaneously after adjustable injection and combustion gas mixing effect thus make final fuel gas buring abundant.This air ejection adjustment structure can make kitchen range adapt to kinds of gas sources, and adaptability is wider.
