FEA Study of Pre-Fill Valve
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2017, Vol 5, Issue 6
Abstract
Pre-fill valve is Pilot-operated check valve which is designed to permit free flow in one direction and to block return flow, unless pilot pressure is applied. However, under pilot pressure, flow is permitted in both directions. In hydraulic systems, it is used as a pre-fill valve to permit the main ram to be pre filled during the “fast approach” cycle of a system operation.The main objective of this work is to design and analyze the different components of high pressure pre-fill valve based on the specifications and type of applications. The development of high pressure pre-fill valve is needed mainly for pre filling the main ram of high capacity hydraulic presses such as extrusion, forging, lamination, metal working, rubber molding presses during their fast approach operation and many other heavy duty applications. Pre-fill valve design is based on the pressure and temperature ratings i.e. operating pressure and temperatures. Industrial pre-fill valves are available in different Nominal sizes ranging from NG 25 – NG 200 for a working pressure below 35 MPa. Finite Element Analysis (FEA) is carried out for all the critical components/parts of this high pressure pre-fill valve by using the analysis software. Here ANSYS software has been used to carry out the FEA, which uses finite element method for solution. The methodology followed in this work is comparisons between the Analytical and Finite Element Analysis results.
