Description
Technical field
The present invention relates to a kind of multichannel water demineralization and processing control valve, be mainly used in the alternate run realizing left tank and right tank in water softener.
Background technique
At present, no matter underground water or surface water all exist calcium, magnesium plasma severe overweight, problem that water hardness is large.Water hardness is easy to greatly fouling in pipeline, causes pipeline blockage.Particularly mining, tunnelling, tunnel excavation, material transportation etc. produce the fog head water hardness in dirt place especially greatly, and often generation incrustation scale comes off and blocks the situation of fog head, therefore need to install water softener and carry out sofening treatment to water quality.
Existing water softener mainly comprises the tank body that epoxy resin is housed, and each operation cycle of tank body carries out normal water supply, loose bed, regeneration, little cleer and peaceful clear greatly five operations successively.Wherein, normal water supply is hard water and enters tank body export softened water after epoxy resin process; The pine bed epoxy resin be in tank body slowly unclamps until unfold completely, and this operation tank body is neither intake also not water outlet; Regeneration is and inputs saline solution in tank body, to be cemented out by the compound of the calcic be adsorbed on epoxy resin, magnesium ion and discharge tank body, so that reuse epoxy resin by chemical reaction; The little press water being clearly small flow enters tank body, rinses epoxy resin, makes the calcium on epoxy resin, magnesium ion sludge discharge tank body, reaches the object of preliminary cleaning; The large press water being clearly large discharge enters tank body, rinses epoxy resin, makes the calcium on epoxy resin, magnesium ion sludge discharge tank body, reaches the object made an overall screening.
In order to realize the continuous process of water quality and the without interruption of softened water, in water softener, be provided with left tank and right tank two tank bodies.Left tank is all connected with softened water control valve with right tank, and is also connected with salt cellar on softened water control valve, for providing saline solution for left tank or right tank, under the control of softened water control valve, and left tank and right tank alternate run.That is: when one of them tank body normal water supply, another tank body carries out loose bed, regeneration, little cleer and peaceful large clear operation successively.
Existing softened water control valve mainly comprises housing and the dynamic taper valve core be engaged in housing, and the patent No. is namely disclose the softened water control valve structure used at present in the patent of invention of ZL97227175.9.Do not arrange in existing softened water control valve and directly can control the structure whether saline solution enters tank body, therefore needing, the connection of mortor operated valve to salt cellar and tank body is set in addition and whether controls.But the fault point of opening, stopping adding system of mortor operated valve, is unfavorable for the stable operation of water softener.
Further, owing to being cone match between spool and valve body, must retain certain gap, otherwise surface friction drag is excessive between spool and valve interior wall, low-power machine cannot drive valve core rotation at all.But once leave gap between spool and valve interior wall, the sealing of spool reduces, inevitably occur that each passage in spool goes here and there the problem of liquid mutually, cause hard water and the mutual seepage of soft water to affect treatment effect; Not only cause left tank or right tank when regenerating because string liquid causes part saline solution to enter work water lines, salt cellar go out that salt amount is large, saline solution utilization ratio is low; And causing left tank or right tank can not seal completely when loose bed, softened water control valve is still outwards a large amount of discharges hard water, causes the serious waste of water resources.In actual production, the volume of design salt cellar originally can make left tank and two cycles of right tank alternate run, and namely salt liquid measure can be used for and uses to four step for regeneration.But because spool string liquid seriously often completes less than a step for regeneration, the saline solution in salt cellar just exhausts, and several step for regeneration are not below because realizing the regeneration function of epoxy resin without saline solution, whole water softener is just as ornaments.As will be normally used, can only every day to salt adding in salt cellar 2 ~ 3 times, not only increase operating cost, increase again the workload of maintenance.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of the multichannel water demineralization and the processing control valve that do not need to arrange in addition salt cellar control valve, for the stability that Demineralizer of increasing water quality runs.

Working principle of the present invention is as follows:
Just turn in the primary importance that right passage 5d is communicated with right water channel 8b at spool 8, left passage 5b and left water channel 8a disconnects, left tank enters loose bed operation right tank normal water supply: pending water from the total water inlet 6a of lower end cap 6 successively through the right passage 5d of base plate 5, the right water channel 8b of spool 8, the right liquid entering hole 4b of the second annular groove 82 and lower valve body 4 enters right tank, flow out from right tank after right tank sofening treatment, again successively through the right liquid return hole 4d of lower valve body 4, 4th annular groove 84 of spool 8, the right water supply hole 3f of right back flow channel 8k and upper valve body 3, first connecting passage 3g and total water-supplying mouth 3b exports softened water.
Then spool 8 rotates clockwise 45 °, spool 8 turns in the second place that right passage 5d is communicated with right water channel 8b, left passage 5b and left water channel 8a disconnects, left tank enters step for regeneration right tank normal water supply: because pendular ring road 8k ' is returned all in the arc of 135 °, so the flow direction of pending water is the same with the flow direction of a upper position in the right passage 5d of base plate 5 and the right side of spool 8 end face; Simultaneously, the saline solution of salt cellar enters left tank through the left salt solution hole 5c of the first annular groove 81 of spool 8, left recovery passage 8e, base plate 5 and left salt liquid interface 10 successively from the saline solution entrance 4a of lower valve body 4, the sewage produced after saline solution reacts in left tank flows out from left tank, more successively through left pollutant exhaust hole 3e, the second connecting passage 3h and total sewage draining exit 3a effluent of the left liquid return hole 4e of lower valve body 4, the five rings groove 85 of spool 8, left back flow channel 8m and upper valve body 3.
Then spool 8 rotates clockwise 45 °, spool 8 turns in the 3rd position that right passage 5d is communicated with right water channel 8b, left passage 5b and left water channel 8a disconnects, left tank enters little clear operation right tank normal water supply: the flow direction of a part of pending water is the same with the flow direction of a upper position, simultaneously, the pending water of another part is through the left cleanout 5a of base plate 5, the little clear and coherent road 8g in a left side of spool 8, the left liquid entering hole 4c of the 3rd annular groove 83 and lower valve body 4 enters left tank, the sewage left tank being rinsed to rear generation flows out from left tank, again successively through the left liquid return hole 4e of lower valve body 4, the five rings groove 85 of spool 8, the left pollutant exhaust hole 3e of left back flow channel 8m and upper valve body 3, second connecting passage 3h and total sewage draining exit 3a effluent.
