The bottom of one of dividing plate 2 is closely connected with flow cell housing 10, upper end is hanging, 24 upper end and the flow cell housing 10 of dividing plate
Close connection, one end are hanging, and in inlet area, the 10-1 lower wall of flow cell housing 10 sets water inlet end 1, in drainage 10-
3 top surface of flow cell housing 10 sets water side 5, the inner chamber of flow cell housing 10 is formed serpentine water-flowing path；Water side 5
Counterbalance valve 6, the communicated drainage pipeline 8 of siphon destructive device 7 are passed sequentially through, forms anti-dewatering in siphon type structure.
In the present embodiment：
Drain 9 is set in the top surface of siphon destructive device 7, siphon destructive device 7 is formed and leads directly to atmospheric strument.The two of dividing plate
4 top is provided with micro- shape linked hole 11, to form the additional discharge air structure of the inner chamber of flow cell housing 10.
Dividing plate at 24 liang of one of dividing plate set inside flow cell 2 and dividing plate, avoids into water and flings instrument electrode
3, it slow down water velocity.It ensure that additionally by counterbalance valve 6 and water be full of in flow cell, protect whole flow cell and inlet pipeline
Malleation is held, air entrance is avoided, prevents Carbon Dioxide in Air to be dissolved in water influence conductivity measurement.Also by siphon
Destructor 7 so that discharge pipe line 8 is only capable of leaning on Overflow drainage, can not form siphon, it is ensured that flow cell is not influenceed by draining, from beginning
To water state is maintained eventually, it can also play a part of protective meter electrode 3.Drain 9 is the additional composition portion of siphon destructive device 7
