There is any restriction effect.
As Figure 1-Figure 5, a kind of specific structure of the utility model are as follows: the anti-turbulent flow low liquid level of big flow vacancy communication type
Device is provided with seal chamber 15 in 31 bottom surface of cooling tower bottom basin；Liquid-level switch 16 is vertically installed on 15 bottom surface of seal chamber；
Straight pipe 11 is vertically installed on 31 bottom surface of cooling tower bottom basin to be located at right above liquid-level switch 16；The cooling tower bottom basin 31
Mounting hole 17 is provided on bottom surface to be located in straight pipe 11；16 upper end of liquid-level switch extends into straight-through across mounting hole 17
In pipe 11；15 bottom surface of seal chamber is connected with stainless steel flexible hose 30；30 other end of stainless steel flexible hose connects threeway 25；Institute
25 upper end of threeway connection cooling tower bottom basin 31 is stated, lower end connects inlet valve 27.
Preferably, 11 upper port of straight pipe is higher than the liquid level of cooling tower bottom basin 31.
Preferably, 11 upper port of straight pipe is provided with filter screen 32.
Preferably, bottom flange 13 is provided on the mounting hole 17；It is threaded on the bottom flange 13 dismountable
Mounting cylinder 12；The mounting cylinder 12 is connect with straight pipe 11.
Preferably, collision mat 14 is provided between 15 bottom surface of the bottom flange 13 and seal chamber.
Preferably, 16 upper end of liquid-level switch is higher than 31 bottom surface of cooling tower bottom basin.
