Flow Analysis and Measurement of Pressure Distribution along Inclined Circular Valve Reeds of Reciprocating Compressor

왕복동형 압축기의 경사진 원판형 밸브리드에 대한 압력분포 측정 및 유동해석

The valve is the key part which governs the efficiency, noise and reliability of the compressor, so the development of analytical model about valve performance is necessary. As the valve leed is opened and closed by pressure pulsation, the flow characteristic of the refrigerant passing the valve is very important. In the present study, a circular disk with inclination is assumed to be the valve reed of a reciprocating compressor and numerical analysis of three dimensional velocity fields are perfomed for the radial flow through the valve model. The effective flow and force area which are required to predict the efficiency of the valve are measured and compared with the numerical analysis in this research.
