多年来,格鲁吉亚水利工程和土壤改良科学研究所对在水压力作用下的自动化放水工作做了大量的研究。《压力管网的流量自动控制器》及其改进后的《有压管网自动放水装置》均属此项研究工作的成果。压力管网流量自动控制器乃是把直径相同的主导管1用法兰2联接起来(图1)。为了形成(来自下面的)自由射流,镶嵌有 Over the years, the Georgian Institute of Hydraulic Engineering and Soil Improvement has done a great deal of research on automatic drainage of water under water pressure. “Pressure pipe network flow controller” and its improved “pipe network with automatic drainage device” are the results of this research. The pressure pipe network flow controller connects flanges 2 with the same diameter of the main pipe 1 (Figure 1). In order to form a free jet (from below), inlaid with
