Ein System hat 8 parallelele管道,每个管道上有1个调节阀。今天突然出现8个管道的调节阀有5%的开度但不同,但管道没有流量。总管上有压力表显示有压力。然后我动了一下调节阀后又恢复流量了。请问一下这是怎么回事? 介质是水温度在6度左右。谢谢!

可能是每个管道出口处的压力调节不同。

调节阀有5%的开度但开度偏小调节效果不理想较理想的范围应该在3%%到8%之间。开度太小控制的流量太小不准确阀门可能存在死区动作不灵敏。建议阀门开度变大或阀座缩小以提高开度。

开度太小调节效果差调节阀开度正常到8%%之间效果最好蝶阀开度最小开度都不能低于15%的。试试开大一点

开度太小流速太快发生闪蒸介质气化了
