Abstract
A distributor cap of a furnace end of a gas furnace is characterized in that the distributor cap is of a hollow disc shape, a plurality of upward-protruding first combustion rings are arranged on the disc face of the distributor cap, a plurality of gas outlet holes are formed in each first combustion ring and connected with a gas mixing cavity below the disc face, and a second combustion ring and a third combustion ring are further arranged between inner holes of the distributor cap and the disc face. The gas outlet holes include the outer ring gas outlet holes and the inner ring gas outlet holes, and a ventilating gap is formed between the outer ring gas outlet holes and the inner ring gas outlet holes. The distributor cap has the advantages that the distributor cap is simple in structure and low in production cost and improves market competitive power, the combustion rings which are separated from one another allow air to enter the distributor cap, oxygen supply capacity of the distributor cap is enhanced, the thermal efficiency is improved, the gas outlet holes are formed in the combustion rings, flames with the small flow but the large number are formed, and the defects that a traditional distributor cap is long in flame and low in efficiency are overcome on the premise that contact with the air is facilitated.
Description
Technical field
The utility model relates to a kind of gas furnace accessory, specifically a kind of gas furnace end fire cover.
Background technology
The burner of currently available technology divides fire cover, it comprises body, and described body consists of endocyclic tube, outer shroud cylinder and top cover, has the trough of flame or the glory hole that connect outer shroud barrel on described outer shroud cylinder, the angled outside injection of glory hole and lid lower surface, endocyclic tube is cylindrical.Existing problems are: Surface Machining is inconvenient, and clean endocyclic tube is inconvenient; Flame annular cylinder shape burning outside, combustion gas injection power is little, and thermal loss is large.Moreover, existing distributor cap for gas furnace is provided with poroid or slot-shaped venthole, these venthole diameters or gap are all larger, so the speed that combustion gas is overflowed is very fast, so the time of contact of combustion gas and air and contact area are all smaller, so easily cause combustion gas for hypoxgia, shine into the thermal efficiency low, fuel can not fully burn and form flourishingly, causes the drawbacks such as waste.
Utility model content
The purpose of this utility model is the shortcoming existing in order to overcome prior art, provides a kind of simple in structure, easy to use, and the thermal efficiency is high, the gas furnace end fire cover of good looking appearance fashion.
The utility model object realizes with the following methods: a kind of gas furnace end fire cover, it is characterized in that: described minute fire cover is the discoid of hollow, card is provided with some the first fire rings that raise up, in the first fire ring, be provided with some ventholes and be connected with the mixed air cavity of card below, between the endoporus of minute fire cover and card, be also provided with the second fire ring and the 3rd fire ring.
Described venthole is divided into outer shroud venthole and interior ring venthole, between two ventholes, is provided with ventilation gap.
The first described fire ring is protruding cylinder table shape.
The first described fire ring is protruding circular cone shape.
The first described fire ring has eight, and evenly permutation is distributed in card.
The beneficial effects of the utility model are: 1) simple in structure, production cost is low, improve the market competitiveness.2) fire ring being separated from each other is conducive to air and enters in minute fire cover, strengthens a minute fire cover oxygen delivery capacity, promotes the thermal efficiency.3) venthole that gathers on fire ring, forms flow little, but the many flare of quantity are being conducive under prerequisite contact with air, avoids traditional minute fire cover flame long, inefficient drawback.
Accompanying drawing explanation
Fig. 1,2 is the utility model structural representation.
Fig. 3 is the utility model structure cutaway view.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is made to concrete further instruction.A kind of gas furnace end fire cover, it is characterized in that: described minute fire cover is the discoid of hollow, card 1 is provided with some the first fire rings 2 that raise up, in the first fire ring 2, be provided with some ventholes 21 and be connected with the mixed air cavity 3 of card below, 1 of the endoporus 4 of minute fire cover and card are also provided with the second fire ring 5 and the 3rd fire ring 6.
Described venthole 21 is divided between outer shroud venthole 211 and interior ring venthole 212, two ventholes and is provided with ventilation gap 213.
The first described fire ring 2 is protruding cylinder table shape.
The first described fire ring 2 is protruding circular cone shape.
The first described fire ring 2 has eight, and evenly permutation is distributed in card 1.
Operation principle: first combustion gas mixes first with air in mixed air cavity 3, then through venthole, flow out, burned on fire ring surface, wherein, in the utility model, between several fire rings, there is certain distance, therefore the air outside minute fire cover more easily enters in lid and contacts fuel gas from this space, realizes the object of comprehensive oxygen supply, has avoided tradition minute fire cover to support the not enough flourishing phenomenon that causes to inner ring combustion gas.Therefore meanwhile, the aperture of several ventholes that arrange on fire ring is relatively little, so velocity ratio is lower, forms the lower but flame group that quantity is many of flame height and is therefore more conducive to the flame envelope that temperature is higher the bottom of a pan is heated.Therefore compare with conventional art, the utlity model has the advantages such as the thermal efficiency is high, and modern design is attractive in appearance, therefore can extensively promote the use of.
More than show and described basic principle of the present utility model and principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; that in above-described embodiment and description, describes just illustrates principle of the present utility model; do not departing under the prerequisite of the utility model spirit and scope; the utility model also has various changes and modifications; as shape of fire ring etc., these changes and improvements all fall within the scope of claimed the utility model.
