Description
Technical field
The present invention relates to technical field of kitchen wares, more particularly to a kind of three ring group mould assemblys applied to burner for household gas range
Full direct injection distributor.
Background technology
The target group of burner extensively, there is the fields such as boiler, smelting furnace, smelting furnace, heat treatment, the row relevant with heat energy
Industry, combustion system is essential.Burner is also the device system for making fuel and air spray mixed combustion in a certain way
Claim, it is several with application field point industrial burner, combustor, civilian burner, special kind firing device by type.
In the burner concept of broad sense, water heater, the gas range of family expenses, or even lighter etc. can be assumed that it is burner
One kind, by its operation principle, burner can be defined as to a kind of this chemical reaction mode of burning that passes through material and turned
Change a kind of equipment-i.e. by air of heat energy with fuel by pre-mixing apparatus by proper proportion mix and convert so that it fully burns.By combustion
Material mode is divided into oil burner, gas burner and dual fuel burner, oil burner be classified into again bumer of light fuel,
Heavy oil burner etc., gas burner is then divided into neat gas burner, town gas burner etc.；By the Combustion System of burner
Model split：Single hop ignition combustor, double sections of ignition combustors, proportioning burners.It is mechanical by fuel atomization model split
Atomising burner, medium atomizing burner；Monoblock type burner and Split type combustion device are divided into by structure.
Distributor structure is general to be made up of point igniter cap and fulcrum bearing, and fulcrum bearing is ring-type, and its thickness is not limited, in the middle part of fulcrum bearing
Hole be mixed airway jack, the diameter for mixing airway jack is suitable with the diameter of mixed airway, and can be supported on fulcrum bearing
On the convex shoulder on mixed airway top；The outer rim of fulcrum bearing is local to be connected with a point igniter cap supporter, point igniter cap supporter and a point igniter cap
It is connected, point igniter cap is the hollow circular cylinder of top closure, and it is coaxial with fulcrum bearing, mixes airway tip portion insertion point igniter cap
In hollow cavity, it is between fulcrum bearing because the presence of point igniter cap supporter forms flat-shaped gas outlet.
This case is it is important to note that existing fire distributer device has some defects, for example, first, it is impossible to make
Secondary air supply needed for burning evenly more comprehensively, the inadequate uniform concentration of flame envelope firepower, it is impossible to most directly effective to improve
The thermal efficiency；For another example, it is impossible to produce high intensity flame；And for example, in three ring small fire independent burnings, exist without sufficiently stable firepower
Thermocouple protects fire hole normal combustion, once gone out by wind, and three ring small fires can not export to thermocouple rapidly and protect fire hole, cause valve
Body closes valve.
Therefore, in view of the above, needing reasonably to improve prior art.
The content of the invention
For disadvantages described above, the present invention provides one kind and is advantageously implemented full premix air suspended type efficient burning, most can directly have
The raising thermal efficiency of effect, can export sufficiently stable firepower by electric thermo-couple protector normal work be applied to household gas range
The full direct injection distributor of three ring group mould assemblys of burner, to solve many deficiencies of prior art.
To achieve the above object, the present invention uses following technical scheme：
A kind of full direct injection distributor of three ring group mould assemblys applied to burner for household gas range, including outer shroud distributor,
The outer shroud direct-injection net being placed at the top of outer shroud distributor and two or three ring integral type distributor, be placed at the top of integral distributor two
Three ring direct-injection nets, some outer shroud fire output holes of outer shroud direct-injection netlist EDS maps, outer shroud distributor inner ring leads fire with outer shroud
Some outer shroud premix chambers are set inside hole and this outer shroud distributor, and the outer shroud premix chamber inner homogeneous sets four outer shrouds point
Block is flowed, outer shroud branching block edge carries outer shroud positioning hole；
If some two rings fire output holes of two or three ring direct-injection netlist EDS maps and two or three ring direct-injection net centers distribution
Dry three ring fire output holes；The integral type distributor outer ring carries ignition electrode fire output hole, and the ignition electrode fire output hole adjacent position is opened
If thermocouple protects fire hole and this thermocouple protects fire hole and leads the inner ring that fiery main channel is communicated to integral type distributor by three rings；Institute
State and three ring premix chambers and the shape between the three rings premix chamber and integral type distributor are set at integral type distributor inside center
Three vertical rings of setting lead fire hole inside Cheng Erhuan premix chambers, two rings premix chamber therein and this three ring leads fire hole lower end with inclining
Three rings tiltedly set are led fiery main channel and are connected, and the integral type distributor bottom surface opens up two or three ring distributor positioning holes.
Using when, the distributor is installed on inside the air distribution disk of burner for household gas range, and the air distribution disk top surface is carried
Baffle in outer shroud distributor, the surface of outer shroud point gas passage is fixed on by positioning by four outer shroud point gas passages, should
Air distribution disk lateral surface is with four two or three ring secondary air supply passages, and the air distribution disk lumen centers set three rings point gas passage simultaneously
And three ring point gas channels peripheral is distributed four two rings point gas passage, this two ring point gas channels peripheral adjacent is with two or three rings point
Firearm positioning hole；
The fixation outside burner main body and the ring injection passage of burner bottom part body three is fixedly mounted below the air distribution disk
Three ring spray mouths are fixed and connect three ring air doors by block, and the burner body interior ecto-entad sets gradually an annular space and mixes chamber, two
Annular space mixes chamber, three annular spaces and mixes chamber；
Access induction tunnel main body on the outside of burner main body, the induction tunnel main body is solid by outer shroud induction tunnel, two ring induction tunnels, nozzle
Determine to connect outer shroud nozzle, two ring sprays by outer shroud air door, two ring air doors respectively successively on the outside of block composition, nozzle fixed block therein
Mouth.
The beneficial effect of three ring group mould assemblys full direct injection distributor of the present invention applied to burner for household gas range
It is really：
(1) by using full direct injection combustion, the uniform dense distribution of direct-injection net fire output hole at the top of distributor, allow burning institute
Evenly more comprehensively, upward direct-injection can be reduced to fuel gas flow formation the secondary air supply needed relative to other combustion systems
Resistance, because gaseous-pressure abundance causes flame flame envelope high and firepower uniform concentration, realizes full premix air suspended type efficient burning, fire
Flame temperature is up to 1000 DEG C or so, most directly effective to improve the thermal efficiency；
(2) four branching blocks are provided with the premix chamber of outer shroud distributor and four outer shroud passages of air distribution disk are distributed in just
Top so that combustion gas can be evenly distributed in distributor premix chamber, is then uniformly sprayed by direct-injection net fire output hole, is produced
High intensity flame；
(3) the ring single-piece mesh direct-injection of two ring three, in three ring small fire independent burnings, can export sufficiently stable firepower and exist
Thermocouple protects fire hole normal combustion, even if unexpected gone out by wind, and flame also can be led fire hole by three rings rapidly and passed by three ring small fires
It is delivered to thermocouple and protects fire hole by electric thermo-couple protector normal work.It is truly realized small fire enough steady.
