| description | The utility model relates to the technical field of nozzles, and discloses an integrated fracturing nozzle which comprises a nut, a transition column and a screw, a conical cavity is arranged in the nut, the transition column is fixedly connected to the center of the upper end of the nut, the screw is fixedly connected to the upper end of the transition column, and the nut, the transition column and the screw are integrally formed. Hexagonal holes are respectively formed in the transition column and the screw rod and are communicated with the conical cavity. According to the integrated fracturing nozzle provided by the utility model, not only is the high wear resistance of the inner hole of the nozzle flushed by high-pressure and high-speed jet flow of fracturing fluid and abrasive particles when an ejector works met, but also the impact resistance and sand backwash erosion wear prevention of the threaded pressing sleeve are met, so that the comprehensive performance of the fracturing nozzle is greatly improv |
