Structure Optimization Design of Axial Flow Check Valve

Abstract:

In order to enhance the performance of axial flow check valve, the nozzle and disk structures are improved. Contrast four different kinds of valve structure by CFD and get the valve structure of minimum flow resistance. By UDF and dynamic grid technology the whole process of the valve opening is simulated and the motion characteristics of the valve are achieved. It can verify the dynamic characteristic of the valve is improved, and the relative error is less than 2%. By analyzing dynamic characteristics of different inlet pressure, the axial flow check valve with optimized structure has reduced flow resistance, improved stability and longer service life.
