STUDI ALIRAN AIR PADA BALL VALVE DENGAN BUKAAN 1/4,2/4,3/4,4/4 MENGGUNAKAN METODE SIMULASI COMPUTIONAL FLUID DYNAMICS

Abstract

Valves are mechanical devices that regulate fluid flow or pressure. Its function can close or open the flow, control the flow rate, divert flow, prevent backflow, control pressure, or reduce pressure. The problem commonly encountered is that the valve closure is not perfect due to the impurities that prevent the cover from closing completely. The simplest handling is to clean the holder from the dirt-dirt earlier and do lubrication. This study aims to explain the description of the flow simulation on ball valve And explain the comparison of pressure, temperature and velocity of water distribution in two types of valve heads. Fluid pressure under closed conditions is different from open conditions. This will affect the strength of the ball valve and butterfly valve as a valve. Pressure that is large or exceeds specifications will affect the working mechanism and material strength. The effect of this pressure becomes very important in the ball valve and butterfly valve because of fluid pressure with temperature, under certain conditions it can be outside the specification limits, especially in Sanitary SS316 Mounting Pad 3-inch ball valve and SS 304 3 inch Sanitary butterfly valve. The method used is Computational Fluid Dynamics with the help of Flow Simulation Solidwork 2014 Software.
