摘　　要：受管道阻力损失影响,气动调节阀的理论流量曲线会发生偏离,固有流量特性在大压差下更容易发生畸变。从理论和试验室条件下的试验数据,分析了曲线偏离的原因,提出在进行调节阀流量试验前,应根据试验室的资源条件提前确定阀门的临界压差,从而保证试验数据的准确性。Under the influence of pipeline resistance loss,the theoretical flow curve of pneumatic control valve will deviate,and the inherent flow characteristics are more prone to distortion under large pressure difference.This paper analyzes the reasons for curve deviation from the theoretical and experimental data under the laboratory conditions,and proposes that the critical pressure difference of the valve should be determined in advance according to the resource conditions of the laboratory before the flow test of the control valve,so as to ensure the accuracy of the test data.
