Pre-filter pre-filter brand _ _ day of pure

Y-type filter backwash filter backwash copper pre-filter (not connected to the pipe by a plurality of valves opening and closing on the formation of recoil and change the flow direction) Principle: When the filter needs to wash retentate prefilter device maintenance, manually or automatically by adjusting the filter itself comes commutation multi-way valve to achieve reversal of flow, so that the flow of water from the raw water strainer (core) of the water side of the raw water side, to recoil purposes. Current common pre-filter backwash normal working conditions are "internal pressure" (because this structure is easier to implement multi-valve design), penetration by water pressure from the inner wall of the filter (core) to the wall, silt, rust and other impurities are trapped particle type within the tube, open the purge valve is trapped by the filter impurities are washed away by water, if you encounter poor water quality, the consumer does not wash for a long time, blocking the filter holes do not worry. By backwash function, then the formation of "external pressure", then embedded in the filter mesh inside (can not afford to be rushing along) pre-filter impurities rankings, will be washed away. The main role of the pre-filter filters sediment pre-filter tap water, rust, large particulate matter.
