Detailed Description
The present invention will be further explained with reference to the accompanying drawings and examples.
As shown in fig. 1 to 7, the high-efficiency induction nozzle of the present invention comprises an upper cover plate 1, a lower sealing plate 2, a ball 3, a felt 4, and a knurled screw 5. Wherein:
(1) The nozzle type adopts a contraction type round sphere, and a contraction cylindrical section is arranged at an outlet, so that the function of contracting the air flow organization is realized.
(2) Thin felt 4 is laid to upper cover plate 1, lower shrouding 2 and 3 junctions of spheroid, uses bolted connection between upper cover plate 1, the lower shrouding 2, can with 3 blocks of spheroid in the centre to adjust clamping power with annular knurl top screw 5, guarantee that spheroid 3 is fixed firm.
(3) The high-efficient induction nozzle is universal adjustable nozzle, can adjust nozzle jet angle as required, and every interval 90 stamp angle regulation scales along 3 circumference of spheroid, the scale precision value is 3, and the supplementary operating personnel carries out the jet angle adjustment.
The utility model has the characteristics of it is following:
(1) The space is saved, and through the structural optimization design, the high-efficiency induction nozzle can replace an air outlet static pressure box, so that the volume of the induction ventilation device is reduced by 10 percent.
