Flow and Pressure Regulating Valve-Fan Blade Structure

The fan blade structure of the flow and pressure regulating valve consists of a valve seat with equally distributed guide fan blades. The uniformly distributed guide vanes force the upstream medium to be divided into many small streams when flowing through the valve. These small streams are vortex-shaped and flow out in a spiral under the guidance of the fan blade diagram. The medium around the valve body and pipeline is forced to change the flow direction. In this way, cavitation bubbles are confined to the center of the pipeline and completely surrounded by the medium (water). Even if these bubbles lose stability and rupture, they will not cause any cavitation damage because they are in the center of the pipeline rather than on the pipeline and valve walls. The high-speed rotating flow of the medium cleans the pipeline wall.
