- Abstract
A compressor valve is a device that controls the flow of higher pressure gas from a reciprocating compressor cylinder. Normally, these valves open and close automatically, solely governed by the pressure differential. The reliability of reciprocating gas compressors depends upon the function of certain critical components. Among these components, compressor valves have become the focus for considerable development, both in design and analysis. In particular, the ring type valve is capable of operating in wide range parameters reaching temperatures up to 200 °C and pressures in excess of 400 bar. Nowadays, Finite Element Method (FEM) is often used for analysis of valve components for optimum pressure differential. This paper highlights finite element analysis of valve seat with the objective to predict the stresses induced in the valve seat at given operating pressure. Further, an analysis was carried out to determine the natural frequencies and respective mode shapes and also to determine whether the valve seat can operate safely for maximum pressure under consideration. The results obtained through modal analysis showed first mode shape in the form twisting and second mode shape in bending. Stress analysis showed the highest stress near the hub of the valve seat.
