湖底水力自控排水排气阀试验研究

Experimental Studies on Lake Bottom Automatic Control Air Evacuation Value and Draw off Value

通过试验确定自控排水排气阀的尺寸和样式。试验中采用压水和压气两种工况,每种工况再进行4种不同条件(阀的直径,阀的高度)的试验,得到各状况下阀头质量和水头之间的关系,最后确定最佳的自控排水排气阀尺寸和样式。

The experiments are designed to determine the dimension and style of automatic control air evacuation value and draw off value. The experiments adopted the bearing test under two different conditions of pressure and pressing air in order to determine the relation between quality and head pressure. Each experiment analyzes and compares four different conditions （the value＇s diameter, the value＇s height）. According to quality and head pressure relation, it has determined on the dimension and style of automatic control air evacuation value and draw off value.
