Embodiment
[0017] The working process of the rotary spray flushing device of the present invention is as follows:
[0018] High-pressure water enters from the interface pipe, pushes the valve core to move down, the valve core moves down in conjunction with the valve stem, the lower end of the valve stem protrudes from the end cap, high-pressure water enters the interface pipe, the impingement turbine drives the valve core to rotate, and then enters the valve cavity through the water inlet hole Enter the blind hole in the center of the valve stem, and then spray out from the spray hole at the lower end of the valve stem along the blind hole. Since the valve core drives the valve stem to rotate, the spray hole rotates to spray water. When the high-pressure water in the mouthpiece is closed, the valve stem As the spool moves up, the injection hole at the lower end of the valve stem retracts upwards into the middle hole of the end cap, the injection hole is closed, and the cleaning operation ...
