Valve.
The utility model makes the water body in air chamber using air pump by the way that the probe assembly of water quality detector is put into air chamber
Discharge outside air chamber, until probe assembly departs from water body, maintenance probe assembly is in the state among air for a long time, so as to block
Condition needed for biological fouling, the formation of probe assembly surface biological fouling in sensor is effectively prevented, due to without chemical reagent
Introduce, so prevented to cause water quality secondary pollution, it is green.And greatly reduce the requirement of system design condition, installation
It is simple and efficient, use can be introduced at any time, and water quality monitoring system coordinates draining control module to realize automation mechanized operation, operating cost
It is low, all kinds of online water quality sensors and system, no use condition limitation can be widely used in.
Brief description of the drawings
, below will be to embodiment in order to illustrate more clearly of the utility model embodiment or technical scheme of the prior art
Or the required accompanying drawing used is briefly described in description of the prior art, it should be apparent that, drawings in the following description are only
