Description
The utility model relates to a kind of selector valve, is specifically related to a kind of current selector valve that the electrodialytic water processing equipment exchanges an end of the two paths between two water intakes and two water outlets that is used for.
Electric dialyzator is the ion that utilizes in the solution, under the effect of DC electric field, move this electrodialysis phenomenon by ion exchange membrane, make former water that the ion migration take place in the compartment of electric dialyzator, the purpose that zwitterion reaches desalination and concentrates by anion and cation exchange membrane respectively in the former water, therefore, former water except that discharging utmost point water, can obtain a concentrated stream and a freshet behind electric dialyzator.When yet electric dialyzator works long hours,, cause " polarization " to lose efficacy because of fouling on the ion exchange membrane if do not switch polarity of electrode.In order to eliminate electrodeposition, improve the working life of ion exchange membrane, electric dialyzator must be switched polarity of electrode behind the operation certain hour.And after electrode switched, freshet originally became present concentrated stream, and concentrated stream originally becomes present freshet, therefore must original fresh water pipe and original dense water pipe commutate, such operation is inconvenience not only, past contact meeting brings error.For addressing this problem, on the electrodialytic water processing equipment, be equipped with four valves, and realize the commutation of current by modes such as automatic or semiautomatic controls, after guaranteeing that electrode is switched, water outlet originally still goes out fresh water, and dense water out originally still goes out dense water.Four valves of this employing and the current reversing arrangement that becomes through control combination, undoubtedly to solving the problems of the technologies described above the positive effect of having played, but the deficiency that exists is: 1. operator must pass through professional training; 2. will finish five actions when operating could realize; 3. complex structure, cost height, volume are big.Especially go up inapplicable at some small electrical dialysis water-treating equipment (as domestic water purifier etc.), therefore, from the present situation of present electrodialytic water processor development, how developing a kind of simple small-sized electrodialysis current selector valve has become a very urgent problem.
The purpose of this utility model provides a kind of small-sized, economic, convenient, practical electrodialysis current selector valve.
For achieving the above object, the technical solution adopted in the utility model is: a kind of electrodialysis current selector valve, mainly form with the valve body that has the circular hole that matches with the spool cylindrical body by having cylindrical spool, respectively have three port holes along circumference respectively on two adjacent radial transverse location of valve body circular-hole internal-wall, first passage hole on each transverse location and second channel hole equal the angle in second channel hole and third channel hole at the angle between radially on the circular-hole internal-wall cross section, and the above angle of transverse location equals the above angle of its another adjacent transverse location, valve body is provided with two water intakes and two water outlets, two water intakes or two water outlets are communicated with two second channel holes respectively, are communicated with the first passage hole and the third channel hole of Different Diameter on transverse location respectively in these corresponding two water outlets or two water intakes; On cylindrical two the adjacent radial transverse location of spool, respectively have two commutation holes along circumference respectively, two commutation holes that respectively have on two transverse location simultaneously with valve body on the first passage hole, second channel hole or second channel hole, the third channel hole is corresponding, and two commutation holes on the same transverse location are communicated with in valve core, in the circular hole of the rotating located valve body of cylindrical body of spool, spool axially be connected with a rotatable handle that stretches out valve body, an end that rotates the two paths between these selector valve two water intakes of rotatable handle and two water outlets exchanges.
In technique scheme, described angle can be 10 °～170 °, the best during 90 ° of wherein said angles; Be provided with the limit stoper of a restriction spool rotation angle between described valve body and the spool; Described two water intakes and two water outlets are communicated with in the valve body body with port hole; Be equipped with the sealing lining in described each port hole or the hole of respectively commutating.
In technique scheme, described " having three port holes along circumference " can be by clockwise or counter clockwise direction open walk hole; Three port holes on described each transverse location, orderliness relation between first, second, third; " be communicated with the first passage hole and the third channel hole of Different Diameter on transverse location respectively " described in the claim in these corresponding two water outlets or two water intakes, mean and routine two kinds of equivalent situations: 1. when aforementioned two water intakes were communicated with two second channel holes respectively, two water outlets were communicated with the first passage hole and the third channel hole of Different Diameter on transverse location respectively; 2. when aforementioned two water outlets were communicated with two second channel holes respectively, two water intakes were communicated with the first passage hole and the third channel hole of Different Diameter on transverse location respectively.
By shown in Figure 3, during certain working position in spool described in the utility model is in the valve body circular hole, the two path water flow point does not enter from two water intakes, flows out through two water outlets of commutation Kong Houcong; If rotate rotatable handle, when making described spool be in another working position in the valve body circular hole, the two path water flow point does not enter from two water intakes, after the commutation of the commutation hole on the spool, flow out from two water outlets, this working state and above-mentioned former working state are in a ratio of two water intakes in the two paths and the connected relation of two water outlets exchanges.
Owing to adopted technique scheme, make the utility model and adopt four valves and compare through the current reversing arrangement that control combination forms, have following advantage:
1. because the utility model mainly is made of spool and valve body, and component are few, and are simple in structure, volume is little, and is in light weight.
2. because the utility model component are few, simple in structure, use common material to make, processing technology is simpler, also not power consumption when using in addition, so cost is low, good economy performance.
3. when using owing to the utility model, only need turning knob can realize the current commutation, manipulate simply, reliable operation has practicability strongly.
