Description
Technical field
The utility model relates to the F23D technical field of burner in a kind of International Classification of Patents F portion, particularly relates to the burner noz(zle) device that can adapt to two kinds of gas with various fuel.
Background technology
At present, it is comparatively extensive that domestic gas equipment is used, and our gas that is used to burn has liquefied petroleum gas, coal gas (being carbon monoxide), natural gas usually.Liquefied petroleum gas is one of oil product.English name liquefied petroleum gas is called for short LPG.Natural gas (Natural Gas) calorific value is 8500 kilocalorie/rice
3It is a kind of gaseous state fossil fuel of mainly forming by methane.The pressure of liquefied petroleum gas and coal gas (piped gas), natural gas is different, so the nozzle bore of combustion gas is different.Usually liquefied petroleum gas pressure big, the gas nozzle aperture is little, and the pressure of natural gas and coal gas is little, the aperture is big, therefore, they can not use with.Oxygen (20.9%) combustion-supporting quantity in the air in addition, i.e. mixing ratio, the air that liquefied petroleum gas requires is many, corresponding other two kinds just few.For example, liquefied petroleum gas stove makes natural gas range into, owing to home-use seldom use forced-air blast, so have only with one times of existing outgassing nozzle aperture reaming; If industrial forced air supply kitchen range also will be turned air door down except reaming, otherwise be easy to stop working." mean value of artificial natural gas and 12T natural gas is generally adopted in the requirement of total specified heat flow precision＜± 10%, determines nozzle diameter in (GB16410-1996) for the thermic load that keeps burner satisfies " household gas utensils ".Keeping under the constant situation of thermic load, the nozzle diameter when using liquefied gas is dg1=0.94mm.Nozzle diameter during natural gas fuel is dg2=1.36mm.Use gas heater, most of natural gas nozzle inner core diameter is 0.6mm, and outer core is 0.8mm, and Y changes T and changes 0.8MM and 1.0MM better usually in order to make flame effect; For keeping identical thermic load, although differing, the nozzle diameter of combustion gas reaches 45%, its injector throat diameter is of slight difference.Therefore can think that when using liquefied gas and natural gas, the injector of burner can be general; Should dwindle incoming air area by suitably adjusting air door, make primary air ratio reach needed value, guarantee normal combustion.Based on above reason, in the prior art, the burner noz(zle) that is suitable for two kinds of fuel gas uses of above natural gas and liquefied petroleum gas is different, can not be general, also be not easy to change, adjust, can not restore behind the manual amendment, and can't guarantee to revise quality, in use have inconvenience.Disclose less and overcome these not enough technology.
Summary of the invention
Goal of the invention of the present utility model provides the nozzle that is applicable to two kinds of combustion gas simultaneously, and this nozzle can be when the source of the gas that conversion is used changes according to the flow velocity of relevant work source of the gas and pressure automatically and carries out self-adjusting spray nozzle device to going out throughput.
Realize that goal of the invention measure of the present utility model is: there is the normal open air flue inside, outer nozzle outlet side and regulates air flue, regulate air flue outlet section inside diameter greater than outside opening, Magnetic force ball is placed in to be regulated in the bigger cavity of air flue internal diameter, fixing magnetic support on this cavity inner wall.
Advantage of the present utility model is, Magnetic force ball cooperates with magnetic support, to such an extent as to according to keeping, reduce to close the adjusting air flue by the different controls automatically of gas flow rate with pressure, realize the nozzle of simultaneous adaptation natural gas or two kinds of gas energies of liquefied petroleum gas, promote overall performance, improve nozzle adaptability, structure is simple and clear, install and use economical and energy saving, safe ready, adaptability is remarkable.
Description of drawings
Fig. 1 is a structural representation of the present utility model
Reference numeral: outer nozzle 1, Magnetic force ball 2, magnetic support 3, core pipe 4, normal open air flue 5 is regulated air flue 6.
The specific embodiment
Below in conjunction with specific embodiment, describe:
There is normal open air flue 5 inside, outer nozzle 1 outlet side and regulates air flue 6, regulates air flue 6 outlet section inside diameters greater than outside opening, and Magnetic force ball 2 is placed in to be regulated in the bigger cavity of air flue 6 internal diameters, fixing magnetic support 3 on this cavity inner wall.
Normal open air flue 5 and adjusting air flue 6 are coaxial fixing.Leave the gap between Magnetic force ball 2 and adjusting air flue 6 inwalls, Magnetic force ball 2 is spherical shape or taper cooperates with reducer inwalls in the adjusting air flue 6.Magnetic support 3 in the form of a ring, strip, spherical, column or sheet.Magnetic force ball 2 and magnetic support 3 are made with metal or permanent-magnet material.
Outer nozzle 1 inner mounting core pipe 4, core pipe 4 inner shafts are to the air flue 6 of adjusting is arranged, constitute normal open air flue 5 between core pipe 4 outer walls and outer nozzle 1 inwall, regulate air flue 6 outlet section inside diameters greater than outside opening, Magnetic force ball 2 is placed in the bigger cavity of core pipe 4 internal regulation air flues 6 internal diameters by magnetic support 3.
Under static state, Magnetic force ball 2 is adsorbed on the magnetic support 3, when the gas-flow of big flow velocity or air pressure by regulating air flue 6 outwards during ejection, air-flow overcomes magnetic force to be promoted Magnetic force ball 2 and moves to withstand on and regulate air flue 6 inner chamber reducing positions, makes that regulating air flue 6 crosses the gas cross section and reduce until closing.
Normal open air flue 5 is coaxial with adjusting air flue 6.Cross section, normal open air flue 5 gas outlet is centered around in the form of a ring to be regulated outside air flue 6 gas outlets.Perhaps, ring-shaped distributed hole, cross section, normal open air flue 5 gas outlet is centered around and regulates outside air flue 6 gas outlets.
The absorption index of Magnetic force ball 2 and magnetic support 3 and operation precision are determined according to two kinds of gentle forcing up the targets of source of the gas flow velocity.Normal open air flue 5 and adjusting air flue 6 sectional areas are according to oxygen and aiding combustion amount in two kinds of source of the gas air pressure and the air, and promptly the mixing ratio index is determined.
When natural gas feeds the utility model, because it is less that natural gas goes out atmospheric pressure, 3 suction-operateds of Magnetic force ball 2 and magnetic support are greater than the air-flow axial thrust, and Magnetic force ball 2 and magnetic support 3 keep absorption, regulate air flue 6 and be in open state, natural gas flows out through normal open air flue 5 and adjusting air flue 6 simultaneously; When liquefied gas feeds, since liquefied gas to go out atmospheric pressure bigger, enter and regulate air flue 6 and promote the suction that Magnetic force balls 2 overcome magnetic support 3 and do mobile in the same way with air-flow, reduce and to blocking the outlet passageway of regulating air flue 6, gas only flows out from normal open air flue 5, thus the difference of the pressure of giving vent to anger according to natural gas and liquefied gas, automatically select outlet passageway, automatically finish the gas flow adjustment, remain on the source of the gas conversion after, combustion-gas flow stable.
