INTERNAL PRESSURE DISTRIBUTION CHARACTERISTICS OF INDUSTRIAL GLOBE VALVES

To investigate the internal pressure distribution patterns of industrial globe valves under varying operating conditions, thereby enhancing valve operational stability and system efficiency, this study employs SolidWorks to establish a three-dimensional geometric model of an industrial globe valve. Computational meshing is performed using ICEM, followed by numerical simulation. Results indicate: Under half conditions, a distinct high-pressure concentration zone exists at the valve orifice, with a tendency for low-pressure vortex zones to form downstream, posing cavitation risks; - Under fully open conditions, pressure distribution becomes more uniform, local resistance is significantly reduced, and system efficiency is enhanced. These findings provide theoretical support for structural optimisation, operating condition selection, and safe operation of industrial globe valves.
