【摘要】：无阀滤池是一种能够自动运行的过滤设备,广泛用于给水和污水处理工程。但由于冲洗水流中挟带大量空气,虹吸过程不能正常进行,致使滤池不能自动运行,常需要人为干预。用联锁器取代无阀滤池的"U"型进水管,可以有效解决冲洗水的挟气问题,从而保证无阀滤池的自动运行。联锁器利用虹吸管的正负压力转换,自动控制进水瓣膜的启闭,可以在滤池冲洗时自动关闭进水,不仅阻断了空气的进入,还节省了水资源;在冲洗完成后,自动重启进水,继续过滤。联锁器既适用于新建滤池,也适用于现有滤池的改造。
[Abstract]:Valveless filter is a kind of filter equipment which can run automatically. It is widely used in water supply and sewage treatment engineering. However, the siphon process can not be carried out normally because a large amount of air is carried out in the flushing flow, so the filter can not operate automatically, and human intervention is often needed. The "U" type intake pipe without valve filter can be replaced by interlocking device, which can effectively solve the gas carrying problem of flushing water and ensure the automatic operation of the valve free filter. The interlock can automatically control the opening and closing of the inlet valve by using the positive and negative pressure conversion of the siphon. It can automatically close the inlet water when the filter is flushed. It not only blocks the air entry, but also saves water resources. After washing, the inlet water is automatically restarted. Keep filtering. The interlock can be used not only in the new filter but also in the modification of the existing filter.
