Numerical Study of the Torsional Movement of the Discharge Valve of a Rotary Compressor
The discharge valve is a key component of the compressor,and the good dynamic char-acteristics of the valve plate could guarantee the economy and reliability of compressor.In order to investigate the rotary compressor discharge valve motion characteristics,this paper uses the com-putational fluid dynamics method(CFD)to establish a three-dimensional fluid-solid interaction calculation model.On this basis,the simulation has obtained the pressure contour in rotary com-pressor,the displacement curve and the impact stress distribution contour of the discharge valve.The results show that the head of valve plate near the oblique incision side impacts lift limiter firstly,but the larger stress appears in the head of valve plate near the cylinder side and the neck of valve plate under the action of the pressure difference and torsional moment,which is easy to bring about the valve plate fracture.
