The utility model is owing to used the PLC programmable logic controller (PLC), so equipment is less, control accurately, good dedusting effect.
In order to make the utility model can be suitable for different water sources and can in the water route, not form dirt deposition, can between described current shunt and water source, also be provided with water filtering mechanism.Described water filtering mechanism can adopt the water filter of various routines as required.
Preferably, the maintenance and the cleaning of water filtering mechanism can also be provided with backwash mechanism on the described water filtering mechanism for convenience, are used for regularly back flush screen pack, prevent that filter screen from stopping up.
Perhaps, described water filtering mechanism also can adopt the filter with backwashing function, does not so just need backwash mechanism has been set especially.
Described start-up control mechanism can comprise hand control switch, control sensor and/or remote control signal; Can be suitable for wherein a kind of as required separately, also can multiple control modes is in parallel use.
In order to save cost,, can be provided with on described magnetic valve and the electromagnetic voltage adjusting valve and regulate the manual fine-tuning mechanism of valve opening degree separately as the further improvement of such scheme.
Compared with prior art, the utility model has adopted the PLC programmable logic controller (PLC), and control is accurate, flexible, good dedusting effect, and the entire equipment volume is less relatively; Simultaneously owing to be provided with water filter and backwash mechanism before the current shunt, so the applicability at water source is good and can blocking pipeline, simultaneously water filter also can be washed timely, scrubbing, structure is practical more reasonable.
