Watering trough low water level floating ball 8 is equipped in wet sump low water level box 5, it is low that the water level of the Watering trough high water level floating ball 7 is higher than Watering trough
The water level of water level float 8 is arranged in parallel between the Watering trough high water level box 4 and Watering trough low water level box 5, water outlet difference
The water inlet of Watering trough drain valve 9 is connected by pipeline, the water outlet of the Watering trough drain valve 9 is connected by pipeline to be drained
Mouthful, the interior case 6 is connected by hose with pressure sensor 10, and the water outlet of the interior case 6 connects laboratory row by pipeline
The water outlet of the water inlet of water pump 11, the laboratory draining pump 11 connects pressure balance mouth by pipeline.
Further, the water outlet of the water tank 1 is arranged in 1 side surface upper part of water tank, the water inlet of the interior case 6 and draining
Mouth is arranged at interior 6 bottom end of case.
Further, the water outlet of the laboratory draining pump 11 connects discharge outlet by pipeline.
Further, the pipeline between the water tank 1 and interior case 6 uses pressure-equalizing pipe.
The utility model compared with the existing technology, has the advantages that
(1) the utility model can carry out automatically moisturizing, and flexible design according to test setting demand, it is easier to control；
(2) the utility model water level sensor avoids the high/low temperature adverse circumstances in case outside chamber, meanwhile,
Fill sensor bucket can pressure-bearing, and be connected to, prevented under vacuum state with interior case by pressure-equalizing pipe, it is right
The influence of water level；
(3) when the utility model does low humidity, the water in case can be taken away automatically, so that moisture is avoided to spread to laboratory,
Shorten low humidity dehumidifying test period；
(4) the utility model moisturizing avoids the requirement to source pressure, as long as in water tank by small pump automatic pumping
There is water, when moisturizing stops, concatenated solenoid valve close synchronously, thus in the case where preventing inside and outside differential pressure, the water of water tank
It is inhaled into interior case；
(5) the utility model maintenance cost is low, and the automation degree of equipment is much higher compared with traditional form, is worthy to be popularized and answers
With.
[Detailed description of the invention]
Fig. 1 is the structural schematic diagram of the utility model；
