Design and Analysis of Butterfly Valve Disc Using Aluminium (1100) and Al-CNT4% Composite Material

Abstract

Aluminium (1100) is an extensively used material in the application of water line and drainage applications. If the aluminium (1100) surface contacts the water, an oxide layer will be formed and it prevents the corrosion of aluminium (1100) when compared to other metal and also it has less weight. But due to their low melting point and low hardness that will wear and deformed easily and cannot be used for high pressure applications. The metal aluminum (1100) will not meet all the required properties suitable for various engineering applications. The present study uses aluminium alloy or aluminium composite material which has the higher melting point and hardness compare to aluminium (1100). In the present study butterfly valve which is commonly used for water line application was designed by using Pro-E software and analyzed its deflection using Ansys software. For the analysis, two materials such as aluminium (1100) and aluminium carbon nanotube 4% was used and compared these two materials deflections, improvements in behaviors are noted. The results of the study indicates that deflection of Al-CNT4% composite is around 7 times lesser than aluminium (1100). Al-CNT4% is more stable than the aluminium (1100) for the application of butterfly valve disc.
