High-wear-resisting flow guide type water nozzle body and manufacturing method thereof

The invention relates to a high-wear-resisting flow guide type water nozzle body and a manufacturing method thereof. A water nozzle comprises the water nozzle body and a flow guide ring. The water nozzle body is obtained through square-to-circle hot extrusion rotary forging, and is inclined towards a forging flow line in an inner hole in a concentrated manner, the flow guide ring is arranged in the inner hole, and an acute angle is formed between the water nozzle inner hole and the flow guide ring in a manner of facing the shrinkage opening end contour line. The manufacturing method comprises the steps of precipitation-hardening stainless steel square-to-round hot extrusion rotary forging forming, stabilizing treatment, flow guide structure welding and stabilizing treatment, machining and conventional refining and the like. The strength is high, self wear resistance is achieved, the water nozzle body can be suitable for irregular high-pressure pulse muddy water flushing, and the flow guide function is achieve
