摘　　要：本文针对暖通空调系统常见的水量连续调节阀动态性能缺失、无法定量表达等问题,提出一种水量连续调节阀动态模型——阀门水力特性状态方程,定量描述调节阀动态调节性能。基于阀门水力特性状态方程,讨论工程现场水量连续调节阀标定的一般方法及应用条件得到所需动态性能方程。对试验阀门的标定试验研究表明该标定方法可行有效,标定结果可满足多数工程精度需求。The paper developed a new dynamic model of continuous control valves,Valve Hydraulic Characteristic Status Equation（VHCSE）,for the unknown and non-quantified dynamic characteristic of control valves.A new calibration method based on VHCSE was discussed about the control valves in field,which exported the VHCSE by fitted a couple of data in reverse processes.The experiments for a test control valve calibration proved that the method is effective and enough accurate for the most needs in the projects.
