摘要
实验研究了不同结构电子膨胀阀在不同工况下的流量特性．得到了膨胀阀的流通面积、阀头结构、膨胀阀入口密度、阀后比容对流量特性的影响，并拟合了流量系数关联式．获得的关联式与实验数据的相对偏差在-12％～4．5％．
Experiments were made to investigate the flow characteristics for different structural electronic expansion valves under different working conditions. The influence of flowing area, structural of valve head, inlet density and outlet specific volume to mass flow coefficient were studied. The flow coefficient correlation was obtained based on the experimental data. The results shows that the relative deviation is in the range of -12%～4.5%.
