Centrifuge atomizing spray nozzle

The utility model provides a centrifuge atomizing spray nozzle which comprises a spray nozzle shell body and multiple cavities, the cavities are arranged in the spray nozzle shell body and provided with openings at both ends, one ends of the cavities are communicated with oil inlets, and second ends of the cavities are communicated with oil spray ports. A whirlcone is arranged in each cavity, a first end of the whirlcone is communicated with the oil inlet, and a second end of the whirlcone is communicated with the oil spray port. With multiple independent oil channels, so that the centrifuge atomizing spray nozzle has a wide oil supply scope, and good in fuel atomizing quality in the wide oil supply scope. When fuel amount for an engine is small, only one oil channel can be opened so as to improve oil supply pressure and improve atomizing quality. When oil supply requirement is added, the multiple oil channels can be simultaneously chosen to supply oil so as to ensure that oil pressure of maximum oil supply d
