A kind of metallic fiber fire lid that is used for gas kitchen ranges
Technical field
The utility model is a kind of metallic fiber fire lid that is used for gas kitchen ranges, belongs to the improvement technology of the metallic fiber fire lid that is used for gas kitchen ranges.
Background technology
Existing strong drum-type gas kitchen range fire cap generally adopts copper fire lid, its fire hole area is subjected to the restriction of fire lid structure itself, make the total fire hole area of fire lid less than normal, thereby make the kitchen range firepower little, the thermal efficiency is low, and carbon monoxide exceeds standard in the gas fume after burning, and when burning flame drawn very longly, what need like this that the kitchen range pan bracket does is very high, makes kitchen range not attractive in appearance.
The utility model content
The purpose of this utility model is to consider the problems referred to above and provides a kind of and can fully burn, thermal efficiency height, and carbon monoxide and amount of nitrogen oxides are low in the flue gas, do not influence the metallic fiber fire lid of the gas kitchen ranges of kitchen range outward appearance.
The technical solution of the utility model is: a kind of metallic fiber fire lid of gas kitchen ranges, it is characterized in that comprising hollow fire lid body, metal web and metal perforated plate, metal web and metal perforated plate lid are contained on the port of hollow fire lid body, metal web places the outside of metal perforated plate, and the port periphery of the periphery of metal web and metal perforated plate and hollow fire lid body is solidly installed successively.
Above-mentioned metal web is formed by the metallic alloy fiber braiding, and it is provided with some breathable apertures.
Rule is provided with the some apertures of breathable on the above-mentioned metal perforated plate.
The outside welding or the riveted joint of the port periphery of the periphery of above-mentioned metal web and metal perforated plate and hollow fire lid body have case ring.
The utility model fire lid is because employing metal web and metal perforated plate cover the structure on the port that is contained in hollow fire lid body, metal perforated plate is used for the support metal fleece, combustion gas and air gas mixture are lighted through after the metal web, mist fully burns at the metallic fiber net surface, send the infrared ray circumference behind the metallic fiber net surface high temperature, the efficiency of heating surface is significantly improved, and very abundant because of mist burning, the carbon monoxide and the amount of nitrogen oxides that generate in the flue gas are low, simultaneously, flame can not drawn very longly during burning, and it is very high that the kitchen range pan bracket does not need to do, the kitchen range appearance looks elegant.

The specific embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is described further.
Shown in Fig. 1,2,3,5, the metallic fiber fire lid of the utility model gas kitchen ranges, comprise hollow fire lid body 1, metal web 2 and metal perforated plate 3, metal web 2 and metal perforated plate 3 lids are contained on the port of hollow fire lid body 1, metal web 2 places the outside of metal perforated plate 3, and the port periphery of the periphery of metal web 2 and metal perforated plate 3 and hollow fire lid body 1 is solidly installed successively.In the present embodiment, the port periphery of the periphery of metal web 2 and metal perforated plate 3 and hollow fire lid body 1 is solidly installed successively by welding or riveted joint.
In the present embodiment, above-mentioned metal web 2 is formed by the metallic alloy fiber braiding, and it is provided with some breathable apertures.Rule is provided with the some apertures of breathable on the above-mentioned metal perforated plate 3.Above-mentioned metal perforated plate is used for the support metal fleece.
For making outward appearance more attractive in appearance, the outside welding or the riveted joint of the port periphery of the periphery of above-mentioned metal web 2 and metal perforated plate 3 and hollow fire lid body 1 have case ring 4.
