Mixing high-pressure jet nozzle
The invention relates to a mixing high-pressure jet nozzle. The mixing high-pressure jet nozzle is characterized in that the interior of a nozzle body is provided with a straight-taper flow channel and a fan-shaped flow channel, both of which are independent; the straight-taper flow channel comprises a first transition hole, a first tapered liquid inlet hole and a cylindrical liquid-spraying hole; the first transition hole, the first tapered liquid inlet hole and the cylindrical liquid-spraying hole are connected in sequence; the first tapered liquid inlet hole and the cylindrical liquid-spraying hole are arranged concentrically; the fan-shaped flow channel comprises a second transition hole, a second tapered liquid inlet hole, a cylindrical liquid inlet hole and an elliptical liquid-spraying hole; the second transition hole, the second tapered liquid inlet hole, the cylindrical liquid inlet hole and the elliptical liquid-spraying hole are connected in sequence; the second tapered liquid inlet hole, the cylindrical liquid inlet hole and the elliptical liquid-spraying hole are arranged concentrically; a liquid inlet is combined by a first transition hole and a second transition hole; a mixing outlet is combined by the cylindrical liquid-spraying hole and the elliptical liquid-spraying hole; the first tapered liquid inlet hole, the second tapered liquid inlet hole and the elliptical liquid-spraying hole are wide at the front portion and narrow at the back portion along the liquid-flowing direction; and axes of the cylindrical liquid-spraying hole and of the elliptical liquid-spraying hole are intersected with the included angle being an acute angle. The mixing high-pressure jet nozzle has a large jet area and great jet impact force.
