Specific embodiment
Below with reference to specific embodiment, the present invention is described in further detail, it is described be explanation of the invention and
It is not to limit.
Referring to Fig. 1, the moveable injector device of main jet disclosed by the invention, including main jet 5 and injector
Main body 12, injector main body 12 are made of collapsible tube 7, mixing tube 8 and diffuser pipe 9, which is characterized in that main jet 5 passes through company
Fitting is connected with the disk 6 that 7 phase of collapsible tube is welded, and the central axes direction for enabling main jet 5 to prolong injector main body 12 is horizontal
It is mobile.
The connector includes slideway 1 and the sliding block 2 that can slide in slideway 1 combined with Figure 1 and Figure 2, slideway 1 and is received
The disk 6 of 7 phase of draw welding is connected, it is preferable that slideway 1 is fixed by bolts in injector main body 12 to guarantee slideway 1 not
It is mobile.Main jet 5 is connected by connecting rod 4 with sliding block 2.Dismountable mobile hand cradle 10 is additionally provided in connecting rod 4, when
So, preferably the movement hand cradle 10 can be welded in connecting rod 4.Made by the mobile hand cradle 10 of mobile working nozzle 5
Main jet 5 moves on the central axis of injector main body 12.
Referring to Fig. 3 and Fig. 4, slider shape is U-shaped sliding block, and 1 shape of slideway is U-shaped internal buckle guide rail, and slideway and sliding block cooperate
So that the axis parallel of the sliding block moving direction in slideway and injector main body.As can be seen from the figure sliding block 2 and slideway 1
Structure by design, guarantee that sliding block 2 is stuck in slideway 1 always and will not fall off, and moving direction always with injector central axis
Line direction is parallel.
Referring to Fig. 5, equidistantly open up several screw holes 11 on slideway 1, the circle center line connecting of several screw holes 11 with draw
The axis parallel of emitter main body 12.If the maximum distance between two neighboring screw hole 11 is d, screw bore dia is r, sliding block
2 width is w, then has: w=2r+d.To guarantee that sliding block 2 is moved to any position, there is a complete screw hole 11 in top.
Screw hole 11 is located at the surface of 2 movement routine of sliding block, and sliding block 2 is fixed on the screw that slideway 1 opens up by fastening screw 3
In hole 11.
Since injector is widely used, for different applicable cases, the concrete structure design parameter of injector is different, and
And the design of main jet is also different, illustrates the specific course of work by taking injector application on the burner as an example here:
Main jet 5 is passed through into mobile hand cradle 10 before injector start-up operation and moves away from injector main body 12 1
End, and it is fixed with fastening screw 3.High-pressure gas passes through the air rolled up around suction after nozzle and enters in injector main body 12 together,
Enter combustion chamber after mixing in injector and is ignited burning.It loosens fastening screw 3 at this time and adjusts the position of mobile hand cradle 10,
Injector main body 12 is shifted to, and observes the variation of flame, the more uniform then combustion efficiency of flame distribution is better, the workability of injector
Can be stronger, by the fixed position here of sliding block 2, and tightened with fastening screw 3 to fix 2 position of sliding block.
Under a certain operating condition, pass through after main jet 5 is moved to a certain position injector is made to reach best injection performance
Fastening screw 3 fixes the position of sliding block 2, so secure jet expansion away from injector throat (injector collapsible tube with mix
Pipe intersection) optimum distance.The apparatus structure is simple, easy to process, can pass through mobile working for specific applying working condition
The mobile hand cradle of nozzle come adjust main jet exit to the distance of injector throat position improve the injection ratio of injector from
And improve the injection performance of injector.
