Distinguishes between balance valves and auto flow valves in application, through an analysis of their mechanism, applicability and project examples, and concludes that the balance valve should be used in the system where the resistance (water flow) balance is desired, and the auto flow valve should be used in the system where the constant water flow is needed.
通过对平衡阀与定流量阀两种调节阀的工作原理、使用范围以及工程实例的对比分析，区分了两种调节阀门的不同作用和功能，认为平衡阀宜用在需要保持阻力平衡（ 流量平衡）的系统中，定流量阀宜用在需要保持流量不变的系统中，二者有不同的作用，不能完全相互取代。
