| 摘 要： | 对楼宇自控工程中应用较多的直线流量特性、等百分比流量特性的阀门的理想流量特性进行了推导、分析,指出等百分比流量特性的阀门适用于建筑环境设备系统中空调水系统;阀门的实际流量特性与阀权度S关系密切.实际工程中S的取值应合理选定,对于调节阀一定要按照其流通系数来选择口径.

| Abstract: | Deduces and analyzes the ideal flow characteristics of linear-flow-characteristic valves and equal-percentage-flow-characteristic valves which are fairly commonly used in building auto control projects. Points out that equal-percentage-flow-characteristic valves are suited for air-conditioning water system in building environment equipment system; that the actual flow characteristic is closely related to valve authority S and the value of S in real projects should be reasonably selected; and that the diameter of control valve must be selected according to its transmissibility coefficient. |
