Abstract
The utility model discloses a universal gas stove with an adjustable nozzle hole, comprising a stove frame, a stove surface, an air inlet tube, and a switch. Compared with the prior art, the utility model is characterized in that the air inlet tube is connected with a nozzle whose nozzle hole is adjustable, nozzle whose nozzle hole is adjustable is connected with a combustion head, and the combustion head can adopt a windproof type net stove head. The utility model has advantages that the gas jetting function of the nozzle hole is scientifically separated from thefire-resistant function; when the gas pressure and the gas quality are changed following the varieties of gas, the relevant adjustment is carried out to the nozzle hole, the gas supply quantity can be balanced, and the normal combustion can be kept.
Description
The utility model relates to the burner in the combustion apparatus, is a kind of burner of burning gases fuel.
The gas furnace of existing using gases fuel can not be suitable for multiple combustion gas kind mostly simultaneously, and when gaseous-pressure and quality changed, combustion efficiency also can be subjected to very big influence.Why can produce the problems referred to above, mainly be because the spray orifice on the nozzle of these existing gas furnaces all adopts the maximum diameter of hole of GB regulation, and can't change, in case non-return combustion and blowback, also just produced a series of problem thus, as producing more unmanageable raffinate, duration and degree of heating is too small, and waste fuel or the like.
The purpose of this utility model provides and a kind ofly can adapt to different gaseous-pressure and quality, makes the gas supply amount be able to equilibrium and keeps the adjustable universal gas stove of spray orifice of normal combustion.
Technical solution of the present utility model is: the adjustable universal gas stove of a kind of spray orifice, have grate, boiler face, air inlet pipe, switch, and the difference of itself and prior art is: air inlet pipe is connected to the spray orifice adjustable nozzle, and the spray orifice adjustable nozzle connects combustion head.
Combustion head in the utility model adopts wind-proof type guard burner.Certainly, combustion head also can adopt other suitable furnace head structure forms.
Combustion head in the utility model has 2 or when a plurality of, wind-proof type guard burner and common eyelet formula burner are also used.Certainly, also can all be wind-proof type guard burner or all adopt common eyelet formula burner, or adopt the burner or the burner combination of other suitable construction.
Spray orifice adjustable nozzle in the utility model comprises nozzle body, the nozzle body front end has a spray orifice greater than conventional aperture, spark arrester with a plurality of apertures is arranged in the nozzle body behind the spray orifice, and small aperture is equipped with the spray orifice control valve less than the conventional nozzle spray orifice in the nozzle body.Certainly, the spray orifice adjustable nozzle also can adopt other suitable specific constructive form.
Spray orifice control valve in the utility model adopts the tapering needle-valve, certainly, also can adopt other suitable control valve forms.
Tapering needle-valve in the utility model comprises that front end is through at the syringe needle in the spray orifice, and the shank that links to each other with syringe needle is connected to helical pitch screw and adjusting knob.Certainly, the tapering needle-valve also can adopt other suitable specific constructive form.
Shank in the utility model passes the centre of spark arrester, certainly, when spark arrester be located at not with shank at a center line or other during not with the contacted position of shank, shank does not then pass spark arrester.
Spray orifice in the utility model is positioned on the nozzle head of nozzle body front portion, and nozzle head is screwed onto on the nozzle body.Certainly, also can adopt other suitable specific constructive form.
The utility model has the advantages that: the jet function and the back-fire relief function of nozzle spray orifice are scientifically separated, in gaseous-pressure and quality during with different the changing of combustion gas kind, spray orifice can be done corresponding the adjustment, make the gas supply amount be able to equilibrium, keep normal combustion, safe and reliable, can not produce tempering phenomenon, it is many to be suitable for the combustion gas kind, can be suitable for multiple domestic gases such as liquefied petroleum gas, natural gas, artificial coal gas, carbon five and liquefied synthetic gas well, reduce the generation of liquefied gas residue, but also can play fuel-saving effect.Adopt windproof burner, also can be fit to the use in the wild environment better.
The utility model is described in further detail below in conjunction with drawings and Examples:
Fig. 1 is the adjustable universal gas furnace structure of an a kind of spray orifice of the present utility model schematic diagram.
Fig. 2 is the structural representation of a kind of spray orifice adjustable nozzle of the utility model employing.
Fig. 1 has described an embodiment of the present utility model.On the gas furnace that constitutes by grate 17, boiler face 1, air inlet pipe 18, support 5, electronic ignition pin 4, electronic ignition switch 14, ignition 13, electronic ignition lead 12 etc., two burners (combustion head) 3 and 15 are arranged, burner 3 is common eyelet formula burner, burner 15 is that windproof net cover type burner (also can all adopt windproof net cover type burner or common eyelet formula burner by two burners certainly.Burner 3,15 rear ends are mixing tube 6, and mixing tube 6 joins with spray orifice adjustable nozzle 8, and the joint is connected to air door 7, and spray orifice adjusting knob 9 is arranged on the spray orifice adjustable nozzle 8.Lead in air inlet pipe 18 on the branch road of two burners cock switch 10(or other suitable switches be housed), switching knob 11 is arranged behind the cock switch 10, knob 11,9 etc. all is loaded on the front panel 16 of gas furnace, regulates operation with convenient.Certainly, spray orifice adjusting knob 9 also can be loaded on other correct positions.
Fig. 2 has described the adoptable a kind of spray orifice adjustable nozzle of the utility model.It has a nozzle body 26, be bolted with a nozzle head 21 in nozzle body 26 front portions, nozzle head 21 front ends are spray orifice 22, the aperture of spray orifice 22 is greater than the aperture of conventional spray orifice, be installed with the syringe needle 23 of tapering needle-valve in the spray orifice 22, spark arrester 24 also depending nozzle head 21 is loaded in the nozzle body 26, and a plurality of back-fire relief apertures are arranged on the spark arrester, and the aperture of back-fire relief aperture is less than the aperture of conventional spray orifice.Be fixed with helical pitch screw 27 on the shank 25 behind the syringe needle 23, helical pitch screw 27 is threaded onto in the screw thread in the nozzle body 26, helical pitch screw 27 is connected to adjusting rod 28, and adjusting rod 28 rear ends are spray orifice adjusting knob 9, and sealing rubber circle 29, densification cover 30 and densification nut 31 are equipped with in nozzle body 26 rear ends.In nozzle body 26 sides opening is arranged, the valve body 35(or the pipeline of be threaded body and a cock 10 on the opening) be connected, cock 10 is formed by hanging tight nut 36, packing ring 37, spring 38, packing ring 39, faucet body 41, switch connecting rod 44 and knob 11 etc., has switch through hole 40 in the faucet body 41.The valve body 35 of cock 10 is connected with air inlet pipeline 18.
