Working principle:
In automatic back-washing valveless water filter device operational process, the increasing of the impurity retained on filtering layer in automatic back-washing valveless water filter device
More, sewage is increased by the resistance of filtering layer, and then the pressure difference of filtering layer Inlet and outlet water is caused to need to increase；Not due to water outlet liquid level
Become, the liquid level for causing automatic back-washing valveless water filter device to be intake increases, and causes water level in siphon tedge to increase, when water level rises to
When assisting the nozzle of siphon pipe, water is flowed down from auxiliary siphon tube, increases system vacuum, and siphon tedge water level further rises
It is high；
Since auxiliary siphon tube caliber very carefully causes its downflow flowing to be not enough to balance the water risen in siphon down-comer
Position, so liquid level can cross auxiliary siphon tube and enter siphon tedge in siphon down-comer.When water enters siphon tedge
And when falling, in pipe, vacuum degree is sharply increased, and rising water column converges into one and goes out nozzle in falling water flow and siphon tedge,
Residual air is all taken away in managing, and forms serial siphon water flow.
Promote to backwash the opposite direction when water in water tank follows filtering and enter siphon tedge, and then enters under siphon
Drop pipe drain, filter material layer thus backwashed.During the rinsing process, the water level backwashed in water tank is gradually reduced, and works as water level
When dropping to backwash automatic stopper, backwashes siphon destructing tube nozzle in automatic stopper and communicated with atmosphere, siphon is broken
Bad, flushing process terminates, and filtering restarts.
