Embodiment
[0015] The spray flushing device working process of the present invention is as follows:
[0016] High-pressure water enters from the interface pipe, pushes the rotary valve core to move down, and the rotary valve core moves down in conjunction with the annular piston. During the downward movement of the annular piston, the high-pressure water drives the turbine blades to rotate, and at the same time drives the rotary valve core to rotate as a whole. The downward movement drives the spray punch at the lower end of the valve stem to extend downwards from the end cover, and the horizontal spray hole is opened to implement spray flushing and cleaning operations. When the high-pressure water of the interface pipe is closed, the annular piston resets under the action of the return spring, and the spray punch at the lower end of the ring valve stem retracts upwards into the middle hole of the end cover, the horizontal spray hole is closed, and the spray flushing and cleaning operatio...
