我国集中供热管网系统中普遍存在稳态失调和动态失调的问题。水力失调问题难以克服的原因主要是缺乏准确可靠、使用简单的调控设备。为了减少稳态失调和动态失调对供热管网的影响,在供热管网系统的设计中,调节阀的选择是一个十分重要的环节。 The problem of steady state imbalance and dynamic imbalance in China’s central heating network system is widespread. Difficult to overcome the problem of hydraulic disorders mainly due to the lack of accurate and reliable, easy to use control equipment. In order to reduce the impact of steady-state imbalance and dynamic imbalance on heating pipe network, the selection of regulating valve is a very important link in the design of heating pipe network system.
