Below, structure and the working procedure of the full-automatic running water processing system of being controlled by above-mentioned three position five-way valve in detailed description:
As shown in Figure 6, the full-automatic running water processing system that a kind of three position five-way valve is controlled, this system comprises above-mentioned a kind of three position five-way valve 10, water purification assembly 20 and follow-up water use sector 30, water intake 15 on the valve body 1 of three position five-way valve 10 is connected with tap water water source, water outlet 11 on valve body 1 is connected with the water inlet of water purification assembly 20, the water outlet of water purification assembly 20 is connected with the drainage import 12 on valve body 1, drainage outlet 13 on valve body 1 is connected with the water intake of follow-up water use sector 30, improvement as this running water processing system, water purification assembly 20 comprises filter cylinder 201, be arranged on filtrate upper cover 202 and the filtrate bracket 203 of filter cylinder 201 inner upper and below and mutual opposed formation receiving cavity, connect valve body 1 upper water-out mouth 11 and the connecting sleeve 204 of water purification assembly 20 water inlets and the center tube 205 that is arranged on filter cylinder 201 centers.
In filtrate upper cover 202 and the formed receiving cavity of filtrate bracket 203, be provided with drainage medium 206.
The working procedure that the full-automatic running water processing system of three position five-way valve being controlled below in conjunction with Fig. 3, Fig. 4, Fig. 5, Fig. 6 and Fig. 7 rinses at water purification, back flush, forward is described in detail:
Fig. 3, Fig. 6, Fig. 7 shows the Water treatment of water treatment system, now, the trend of current is: tap water water source-water intake 15-tap water connecting passage 21-water outlet 11-connecting sleeve 204-filtrate upper cover 202-drainage medium 206-filtrate bracket 203-center tube 205-drainage import 12-drainage communication channel 22-drainage outlet 13-follow-up water use sector 30 water inlets, the current drainage medium 206 of flowing through, complete the purified treatment to tap water, increasing along with the need purification water yield, the organic substance being detained in drainage medium 206 is added gradually, the purification function of drainage medium 206 declines gradually, need rinse drainage medium 206.
Fig. 4, Fig. 6, Fig. 7 show the backwash process of water treatment system, tap water water source-water intake 15-tap water connecting passage 21-drainage import 12-center tube 205-filtrate bracket 203-drainage medium 206-filtrate upper cover 202-connecting sleeve 204-water outlet 11-drainage communication channel 22-sewage draining exit 14-sewerage.
During back flush; current reverse flow is through drainage medium 206; due to when the back flush; to having relatively high expectations of hydraulic pressure; pressure reduction structure 24 on three-position five-way valve core 2 can protect spool 2 and valve pocket 3 to be unlikely to impaired effectively; drainage medium 206 can be kicked up along with current are reversed, along with drainage communication channel 22 is discharged from by 14 mouthfuls of blowdowns.But due to by simple back flush, drainage medium 206 is taken up an official post and so had the delay of pollutant, need to carry out a forward and rinse and could effectively remove the organic pollution materials of the delay on drainage medium 206.
Fig. 5, Fig. 6, Fig. 7 show the process of the forward flushing of water treatment system, and current trend is now: tap water water source-water intake 15-tap water connecting passage 21-water outlet 11-connecting sleeve 204-filtrate upper cover 202-drainage medium 206-filtrate bracket 203-center tube 205-drainage import 12-draining communication channel 23-sewage draining exit 14-sewerage.
The pollutant being trapped on drainage medium 206 while rinsing back flush by forward is discharged.
This three position five-way valve is by the knob 4 miter angle conversion to back flush station by water purification station that turns clockwise, knob 4 is rotated counterclockwise miter angle and completes the conversion to forward flushing station by back flush station, and knob 4 is again rotated counterclockwise miter angle and completes forward flushing station to the conversion of water purification station.
More than show and described basic principle of the present utility model, major character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; what in above-described embodiment and specification, describe is principle of the present utility model; under the prerequisite that does not depart from the utility model spirit and scope, the utility model also has various changes and modifications, and these changes and improvements all fall in claimed scope of the present utility model.The protection domain that the utility model requires is defined by appending claims and equivalent thereof.
