摘 要:调节阀是最终控制元件最广泛的使用型式。调节阀用于调节介质的流量、压力和液位。根据调节部位信号,自动控制阀门的开度,从而达到介质流量、压力和液位的调节。在固定式喷灌系统中,采用空气调节阀结构,使用空气流通调节输水管道内气体及真空现象,管道在启运和关闭时,不易产生气、水锤现象,该系统在喷灌管道设计施工中省略了繁杂的气、水锤设计施工,简化了结构设计。Regulating valve is the most widely used type of eventual control components. Regulating valve is used to regulate flow, pressure and liquid level for the media. According to the signal of regulating site, it is able to control automatically the opening of the valve so that it can achieve the regulation of flow, pressure and liquid level for the medium. In fixed sprinkler irrigation system, the structure of air regulating valve is used. The use of air circulation regulates gas and vacuum phenomenon inside the pipeline. The pipeline was not easy to produce gas and water hammer phenomenon when it turned on or turned off. The sprinkler irrigation system has been omitted from complex gas, water hammer in the design and construction of pipelines and it simplifies the structural design.
