| 摘 要： | 恒温阀由恒温控制器(核心元件为感温包)与流量调节阀组成。建立恒温阀控制室内温度的数学模型,对恒温阀的控制特性进行了分析。恒温阀的控制为比例控制,其控制精度由感温包特性、流量调节阀的机械特性、供暖系统计算参数及恒温阀控制环路的滞后性决定。

| Abstract: | The thermostatic valve is composed of thermostat and flow rate regulating valve,the thermostat's key element is temperature sensing packet.The mathematical model for controlling room tem- perature by thermostatic valve is established,and the control characteristics of thermostatic valve are ana- lyzed.The control of thermostatic valve is proportional,and the control precision depends on the charac- teristic of temperature sensing packet,the mechanical characteristic of flow rate regulating valve,the cal- eulation parameters of heating system and the hysteresis of control loop of thermostatic valve. |
