Embodiment: as shown in Figure 1 to Figure 3, valve body 1 is provided with water-in 5, water outlet 6 and sewage outlet 7, and the inside and the outside that also are provided with runner and water treatment system filter core 18 in the valve body 1 are communicated with respectively.Water-in 5 in the valve body 1 is provided with branch flow channel 16 in the runner of filter core 18, be equipped with ejector nozzle 17 in this branch flow channel 16, is provided with salt water inlet 20 on the valve body 1 in ejector nozzle 17 exits, can be connected with the brine tank 21 of water treatment system.Moving valve plate 3 and fixed valve plate 2 that the spool of valve body 1 adopts a pair of end face rotary seal to cooperate, moving valve plate 3 is connected on the valve rod 4.Fixed valve plate 2 end face centers are provided with the sewage outlet 7 that through hole 8 is communicated with valve body 1, also be provided with six through holes on the fixed valve plate 2 around the center, wherein through hole 9 is communicated with the outside of filter core 18, through hole 10 and 12 is communicated with the inside of filter core 18, through hole 11 is communicated with water outlet 6, and through hole 24 and 25 is the ingress and the exit of connecting morphism flow nozzle 17 respectively.The face of being sealed and matched of moving valve plate 3 be provided with one from the center to radial blind hole 13 near the edge, and be provided with a circular-arc blind hole 14 around the center, moving valve plate 3 also is provided with a through hole 15 normal open water-ins 5 simultaneously.Each pore distribution of fixed valve plate 2 and moving valve plate 3 cooperates on same turning circle radius.When producing, fixed valve plate 2 and moving valve plate 3 can adopt differing materials such as pottery, if intensity is not high, can be provided with the separation strap stiffener in the through hole 9 and 10 as fixed valve plate 2 in some bigger through holes, improve intensity.It is a hole that through hole 10 and 12 can be communicated with, but processing inconvenience.
During use, valve body 1 is installed on the water treatment tank 19, and filter core 18 is located in the water treatment tank 19, perhaps directly fills filtering material and constitute filter core 18 in water treatment tank 19, and the runner of valve body 1 and filter core 18 internal communication generally passes through the water distributor 22 of water treatment tank 19.Purify if desired, generally use the filter core 18 or the sand filtration of active carbon material, need the softening filter core 18 that then generally uses resin material.Can be manual or electronic during operation, the automatic motor drive mode rotation valve rod 4 of the more use of industrial water conditioning system makes each the hole cooperation position conversion on moving valve plate 3 and the fixed valve plate 2, carries out different user modes and switches.
Each work user mode of water treatment system explanation present embodiment below by the filter core 18 that uses resin material.Need add salt solution during resin material regeneration, water treatment system can be provided with a brine tank 21 is communicated with valve body 1 by water intaking valve 23 salt water inlet 20.
When normal operation is softening, as shown in Figure 4 and Figure 5, the through hole 9 of the through hole 15 overlapping connection fixed valve plates 2 of moving valve plate 3, blind hole 14 covers on through hole 10 and 11, and through hole 10 and 11 is communicated with.The current via through holes 15 that enters from water-in 5 enters through hole 9, enters in the water treatment tank 19 again, and 18 softening filtrations are come out from through hole 10 through water distributor 22 again through filter core, flow out from water outlet 6 behind through hole 11 through blind hole 14 water conservancy diversion.The current normal flow is crossed water-in 5 to the runner between filter core 18 outsides in this process, and blind hole 13 covers on through hole 8 and 25, does not form passage, branch flow channel 16 no current.
When back flushing, as shown in Figure 6 and Figure 7, the through hole 10 of the through hole 15 overlapping connection fixed valve plates 2 of moving valve plate 3,13 of blind holes cover the through hole 8 and 9 that is communicated with on the fixed valve plate 2, current enter water distributor 22 from through hole 15 via through holes 10 and arrive filter core 18 inside like this, the filter core 18 that recoils out then becomes sewage, enters through hole 9 again and is guided to through hole 8 through blind hole 13, discharges from sewage outlet 7.
When needs are inhaled salt regeneration, as Fig. 8 and shown in Figure 9, the through hole 24 of the through hole 15 overlapping connection fixed valve plates 2 of moving valve plate 3,13 of blind holes cover the through hole 8 and 10 that is communicated with on the fixed valve plate 2, and blind hole 14 covers the through hole 25 and 9 that is communicated with on the fixed valve plate 2.After the current that enter from water-in 5 enter into through hole 24 through through hole 15, through ejector nozzle 17 jets of branch flow channel 16.Current can be in the exit of ejector nozzle 17 behind jet in this process, salt water inlet 20 places that are valve body 1 produce negative pressure, salt solution sucks through salt water inlet 20 by water intaking valve 23 from brine tank 21, salt solution and current mix the back and are guided to through hole 9 from through hole 25 through blind hole 14, enter water treatment tank 19 then, brine stream is crossed filter core 18 regeneration, arrives through hole 10 through water distributor 22, be guided to through hole 8 through blind hole 13, discharge from sewage outlet 7.The water level of brine tank 21 drops to setting place, and water intaking valve 23 can be closed.
After suction salt is finished, because salt solution uses in the brine tank 21, need add water, as shown in Figure 10 and Figure 11, and the through hole 25 of the through hole 15 overlapping connection fixed valve plates 2 of moving valve plate 3,13 of blind holes cover the through hole 8 and 24 that is communicated with on the fixed valve plate 2.Current flow into the exit that branch flow channel 16 arrives ejector nozzle 17 from through hole 15 via through holes 25, because the outlet of ejector nozzle 17 is thinner, most of water inflow salt water inlet 20 enters in the brine tank 21 and adds water, when the water yield is enough, water intaking valve 23 can be closed, as long as it is in brine tank 21, can there be after with salt salt solution to inhale salt, very convenient for regeneration.The small portion current oppositely arrive through hole 24 by ejector nozzle 17 backs, are guided to through hole 8 through blind hole 13, discharge from sewage outlet 7.
In the time of need just washing, as Figure 12 and shown in Figure 13, the through hole 9 of the through hole 15 overlapping connection fixed valve plates 2 of moving valve plate 3,13 of blind holes cover the through hole 8 and 12 that is communicated with on the fixed valve plate 2, current flow to into filter core 18 from through hole 15 via through holes 9 like this, wash then with residual brine go out filter core 18 through water distributor 22 to through hole 12, be guided to through hole 8 through blind hole 13, discharge from sewage outlet 7.
When only needing to purify, can adopt the filter core 18 or the sand filtration of active carbon material in the water treatment tank 19, not need to inhale salt regeneration, as shown in figure 14, salt water inlet 20 can be blocked each working order process and the said process basically identical that normally move purification, back flushing, are just washing.During production, also can not establish branch flow channel 16, ejector nozzle 17 and salt water inlet 20 in valve body 1, also not establish through hole 24 and 25 on the fixed valve plate 2, structure is simplified more.
