A Study on the Orifice Shape of High-Differential Pressure Control Butterfly Valve

초록

Butterfly valves are used in various industries to control the flow rate, flow direction, pressure, andtemperature. These are gaining popularity in the field of plant industry to enable high-differential pressurebecause of their low maintenance costs and ease of installation. This study presents a numerical analysismethod to analyze changes in the flow characteristics of a high-differential pressure control butterfly valvebased on the location and shape of the orifice. The numerical analysis was conducted using a commercialCFD program. The analysis results show a correlation between the orifice shape and cavitation phenomenon.
