The influence of the damping hole parameters on the performance of double nozzle flapper valve basing on the orthogonal test
This paper analyses the flow of the double nozzle flapper valve.Three-dimensional model is established with software Pro/E,fluid analysis software is used for modeling and meshing,CFD method is applied for researching pressure,and flow characteristics of the fixed damping hole is researched when parameters of double nozzle flapper valve is varied.The results show that:the highest velocity through the fixed orifice hole is about 150m/s,the pressure is about 5.9MPa; Using orthogonal test to analyze the simulation results,it is obtained that the power losses of the double nozzle flapper with the change of the diameter,length and the angle of the fixed orifice,the influencing factors on the power losses are the diameter,length and the angle,and the best parameter combination through orthogonal table analysis is gained,which can provide the reference for the whole designing of the double nozzle flapper valve.
