摘要

PURPOSE: A water-jet thrust nozzle comprising bidirectional jetting ports and a water-jet thrust washing method are provided to separate and remove scales from the inner wall of a pipe by the jetting force of a rear jetting port and a brush.;CONSTITUTION: A water-jet thrust nozzle(1) comprises a body(10) and a rotating unit(20). The rear of the front body(12) of the body is coupled to the rear body(11) of the body. A front jetting port(14) is radially formed on the front of the front body. The front jetting port rotates the rotating unit by jetting water to a rotating cover(21). A supply hole(15) is formed on the rear center of the rear body and is connected to a hydraulic horse. A rear jetting port(13) is radially formed around the supply hole. The nozzle is reversely propelled by jetting of water by the rear jetting port.
