The efficient induction nozzle comprises an upper cover plate, a lower sealing plate and a ball, the upper cover plate and the lower sealing plate are connected through a bolt, the ball is clamped between the upper cover plate and the lower sealing plate to form a universal adjustable nozzle, and the jet flow angle of the nozzle can be adjusted according to requirements. The ball body is a contraction type round ball body, and a contraction cylindrical section is arranged at an outlet to achieve the effect of contracting airflow organization. The efficient induction nozzle can replace an air outlet plenum chamber, the size of a same-flow induction ventilation device is reduced by 10%, the outlet speed and the jet range of the nozzle are increased, the total outlet pressure loss is reduced by 30%, aerodynamic noise is reduced, and free adjustment of the jet flow air supply direction within the dip angle range of 30 degrees can be achieved on the premise that the air supply jet range is met.

    本发明涉及一种高效诱导喷嘴,包括上盖板、下封板、球体,所述上盖板、下封板之间用螺栓连接,将球体卡在中间形成万向可调节喷嘴,能按需求调整喷嘴射流角度。所述球体采用收缩式圆形球体,出口处设置有收缩圆柱段,实现收缩气流组织的作用。本发明的高效诱导喷嘴可替代出风静压箱,实现同流量诱导通风装置体积减少10%,喷嘴出口速度、射程增加,出口总压损失减少30%,气动噪声降低,并且可在满足送风射程的前提下,在倾角30°范围内实现射流送风方向自由调整。
