The invention provides a fluid-atomizing mechanical
nozzle, and relates to a
nozzle. The fluid-atomizing mechanical
nozzle comprises a valve body provided with a fluid inlet, a liquid sheet, a spring,a valve needle, a
cyclone seat and a
valve seat, wherein a valve needle through hole I is formed in the middle of the liquid sheet, a counterbored hole is formed in the front end of the
cyclone seatand is in sleeve joint with the rear end of the
valve seat, a valve needle through hole II is formed in the middle of the rear end of the
cyclone seat, cyclone holes are uniformly formed in the periphery of the valve needle through hole II, and the valve needle through hole II and the cyclone holes communicate with the counterbored hole; the spring is mounted between the bottom end of the liquid sheet and the cyclone seat; and a cyclone cavity III communicating with the cyclone holes of the cyclone seat is further formed in the rear end of the
valve seat and communicates with a cyclone cavityI formed at the front end of the valve seat. According to the fluid-atomizing mechanical nozzle, under
differential pressure and centrifugal actions, the conical atomizing effect of fluid is improved,atomizing angle and area are increased, the mechanical nozzle can work stably in high-temperature and high-speed gas for a long time, the fluid is effectively prevented from blocking spray holes dueto high-temperature gumming, and therefore, the service life of the product is prolonged.
