三通调节阀广泛应用于调节热交换器冷热水的进出流量或温度,以满足系统冷热交换的需要。为了得到良好的调节性能,达到人们所希望的开度—热量特性基本按线性变化。本文对不同使用条件下选用何种开度—流量特性进行了论述;也阐述了三通阀应如何安装。强调设计人员在设计中应指明所选用的是何种开度—流量特性,以及三通阀在系统申的水流方向。
Three-way regulating valve is widely used to adjust the inlet and outlet flow rate or temperature of heat exchangers to meet the needs of the system of cold and heat exchange. In order to obtain a good adjustment performance, to achieve the desired opening - the thermal characteristics of the basic linear changes. This article discusses what opening-flow characteristics are used under different conditions of use; it also explains how three-way valves should be installed. It is emphasized that the designer should indicate in the design what kind of opening-flow characteristics are selected and the flow direction of the three-way valve in the system.
