Abstract

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 treatment is to clean the holder from the dirt and dirt intensively and do lubrication. This study aims to explain the description of simulation flow in a butterfly valve. And explain the ratio of pressure, temperature and speed of water distribution to the valve. Fluid pressure under closed conditions is different from open conditions. This will affect the strength of the 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 butterfly valve because of fluid pressure with temperature, under certain conditions it can be outside the specification limits, especially in SS 304 3 inch Sanitary butterfly valve. The method used is Computational Fluid Dynamics with the help of Flow Simulation Solidwork 2014 Software.
