Abstract
The utility model relates to a nozzle, in particular to a high turndown ratio anti-blocking nozzle which aims at solving the problem that an existing nozzle cannot adjust sprayed water flow, and is easy to block. The utility model provides a high turndown ratio anti-blocking nozzle which comprises a nozzle body. A water inlet channel, a water spray hole, and a through hole are formed in the nozzle body. The water inlet channel is communicated with the through hole through the water spray hole. A gas passing core, a flow guide sleeve, a water diversion core and a nozzle head are installed in the through hole. The water diversion core comprises water diversion holes and a water diversion core shaft.
