Abstract

The research on the gas axial flow regulating valve is one of the key tasks for the localization of critical valves in natural gas pipelines. With the main purpose of improving the design of the sleeve of the gas axial flow regulating valve, numerical simulation calculations are conducted on the internal flow passage of the gas axial flow control valve by using fluid simulation software. According to the existing design of the valve sleeve, the design scheme of the valve sleeve is improved by changing the diameter of the throttle hole of the valve sleeve. After improving the valve sleeve, eight simulations have been performed at different openings to analyze the velocity field, pressure distribution, and variations in aerodynamic noise within the flow passage at two design schemes. A comparison is also made between two valves for their respective flow fields and noise characteristics which use two different sleeve designs. The simulation results indicate that appropriately increasing the throttle aperture can improve the flow performance of a gas axial flow regulating valve, reducing noise levels to below 100 dB at medium and small openings.
