1本帖最后由 助跑 于于 2---1111:1 编辑 当在储罐设置氮封和呼吸阀工艺时,, 自后封的自力式调节阀阀前后压力差很大,后阀后是否应扩径呢?例如氮封流量为1标方方/ 标方/小时,氮封阀为DN88,阀后如果还是 还是DN8的话,流速达到1555 m 标5m/s,太大了。请各位大咖给予帮助解疑答惑谢谢。

�阀后需要扩径,阀前阀后都需要计算管径,控制管流速在合理范围之内。

最好配发一示意图,便于讨论。 通常这类带有自力式调节阀的流程,是由一个阀门组组成的。至于扩径应该是必须的。但也要看氮封的实际用量。不知是啥设备用如此之大的的密封流量。

罐的容积多大?压力范围多少? 泵的流量M3多大?

要啊,就当普通调节阀,变径也是常规操作
