空调水系统中电动调节阀流量特性研究
Flow characteristics of the motorized valve in an air conditioning water system
摘要：
指出空调水系统中电动调节阀理论流量特性与工作流量特性的研究需遵循一定的前提条件，而在实际系统中，该前提条件往往无法得到保证，电动调节阀的实际流量特性还与空调水系统形式、阀门所处的位置等诸多因素相关，因此电动调节阀的实际流量特性应为一个范围，而非一条曲线。构建了四类典型空调水系统，计算分析了各类系统中各电动调节阀的实际流量特性。

Abstract：
Points out that the study of theoretic and working flow characteristics of the motorized valve is based on some preconditions, but these preconditions usually cannot be satisfied in an actual chilled water system, and the actual flow characteristics are also related to the type of the chilled water system and the location of the valve, so the actual flow characteristics of the motorized valve should be a range instead of a curve. Establishes four representative chilled water systems, and analyses the actual flow characteristics of each valve in these systems.
