(2) the utility model can improve the flow of domestic water effectively.
In existing non-wastewater discharge Hyperfilevation water purifying machine, domestic water passes through water-purifying machine completely, owing to there is the resistance of filter element filtering, cause the discharge reduction of domestic water, water-purifying machine of the present utility model, in order to improve domestic consumption, adds a by-pass line, adds domestic consumption between raw water tubes line and domestic water tap, the flow of by-pass line be 1:1 by the ratio of the flow of the raw water tubes line of water-purifying machine, thus effectively improve the flow of domestic water.
(3) the utility model can improve the work-ing life of preprocessing filter element before RO membrane cartridge effectively.Reason is as follows:
A, owing to reducing one times by water-purifying machine water pipe flow, so life to preprocessing filter element before RO membrane cartridge one times.
B, change structure and the arrangement mode of the cotton and gac of preprocessing filter element PP before RO membrane cartridge, former first step filter core is the cotton filter cores of 5 micron pore size PP, third stage filter core is the cotton filter core of 1 micron pore size PP, because secondary filter core aperture is more or less the same, when actual filtration impurities in water, the life-span of first step filter core and third stage filter core differs greatly, the utility model first step filter core adopts 20 microns, aperture paper folding filter core and is series relationship, its role is to filter larger particles material in former water, a whole set of filtering system is made to play fine filtering effect after first coarse filtration, and paper folding filter core comparatively cotton its surface-area of filter core of PP increases several times so extend work-ing life.Described secondary filter core, three grades of filter cores are composite filter element, the structure of described composite filter element is the cotton filtrate of the outer PP for 1-5 microns, aperture, it act as and to filter in former water comparatively finely ground particle substance, internal layer is sintering activity charcoal, its Main Function is the chlorine residue in the former water of absorption, and sintering activity charcoal compares its adsorptive power of granulated carbon can reach more than 2 times more by force.Secondary composite filter element, three grades of composite filter elements are adopted to be connected in parallel and more can effectively play its effect.Can pretreated effect and work-ing life before maximum raising RO membrane cartridge by changing mode of connection and changing filter cartridge construction.
(4) of the present utility modelly forced-ventilated defencive function is added without waste water water-purifying machine, when domestic water usage quantity is on the low side, that is: when continuously the Pure-water Making water yield 6 liters and domestic consumption do not reach 6 liters, (the dense water in water machine can be replaced into former water completely when using the domestic water water yield to reach 6 liters) is opened forced-ventilated protection magnetic valve by electric control gear and is carried out forced discharge, automatically close forced-ventilated protection magnetic valve after discharging 6 liters and again add up the water time processed i.e. water yield processed, the injury of non-normal use water-purifying machine to RO membrane cartridge is solved with this, RO membrane cartridge is played a protective role.Described continuous Pure-water Making 6 liters, as forced-ventilated protection node, is just considered the relation of actual pure water water consumption and pure water TDS value and pure water water quality and sets.
(5) of the present utility modelly to coordinate by means of only water pump and current limliting and circulating electromagnetic valve without waste water water-purifying machine, a water pump only need be utilized can to realize supercharging and circulation two kinds of functions, greatly reduce material and production cost, and the structure of water-purifying machine is simpler, be more convenient for assembling and maintenance.
