Summary of the invention:
Object of the present invention is exactly the deficiency in order to solve prior art, and the structure provided is simple, premixed combustion is effective, the Draught gas burner of obvious energy conservation full premix injection control device.
The present invention's adopted technical scheme of dealing with problems is achieved in that and the present invention includes burner, premix barrel, Venturi tube, blast switch, blower fan and gas joint; It is characterized in that: between the high pressure air port and the premix barrel of burner of blower fan, or the air inlet of blower fan is provided with induction tunnel; Be provided with Venturi tube in induction tunnel, be provided with venturi waist hole between the contraction chamber and expansion cavity of Venturi tube, venturi waist hole is circular or long linear hole; There is the gap of 3-8 millimeter between venturi waist hole and induction tunnel, form negative pressure cavity.
Induction tunnel is mounted with gas joint communicate with negative pressure cavity; Be provided with throttling valve core in gas joint, throttling valve core has throttle orifice.
In high pressure air port, place is provided with pressure tap, communicates with blast switch;
Air register is equipped with in air inlet.
Compared with the prior art, beneficial effect is embodied in the present invention:
1, the present invention adopts in induction tunnel and arranges Venturi tube, between the Venturi tube waist hole and induction tunnel of Venturi tube, there is the gap of 3-8 millimeter to form negative pressure cavity, the wind blasted is from contraction chamber through expansion cavity, and combustion gas is introduced expansion cavity uniformly at venturi waist hole place and mixed.
2, the gas joint that the present invention settles on induction tunnel communicates with negative pressure cavity; Be provided with throttling valve core in gas joint, regulate the size of throttle orifice, can thermic load be changed, deduct gas nozzle.
3, the present invention is provided with blast switch at high pressure air port place, improves burner security in combustion and controllability.
4, the present invention is equipped with air register in air inlet, increases the amplitude of accommodation of air quantity.
Accompanying drawing illustrates:
Fig. 1 is structural representation of the present invention;
