Description
Technical field
The utility model relates to a kind of solenoid valve that is used for water purifier, particularly a kind of solenoid valve that is used for the washing and filtering device.
Background technique
Generally all has filtrating equipment in the water purifier, the water source is input to filtrating equipment by an inlet valve, the water purification output terminal of water purification from filtrating equipment flows out, and filtrating equipment often needs flushing (generally being the sediments on the flushing filter core), the addle behind the washing and filtering device then to need another wastewater valve gate control to discharge.In the existing water purifier, this inlet valve 1 ' is two valves that independently separate with waste water valve 2 ', the annexation of both and filtrating equipment 3 ' as shown in Figure 1, arrow is depicted as water (flow) direction among the figure.What inlet valve and waste water valve were more is to adopt solenoid valve, as the patent No. is the Chinese utility model patent " a kind of solenoid valve that is used for the water purifier reverse osmosis filtration system " of ZL03273385.2 (notification number is CN2639628Y), just discloses a kind of solenoid valve that is used for water purifier.This solenoid valve comprises the valve body that has import, outlet, be arranged on valve body one side can spacing mobile spool, the coil that is arranged on the spool periphery and coil cap, have in the valve body one be communicated with import, outlet must through intercommunicating pore, be provided with spring between spool head and the valve body, and but spool left and right sides under the action of a magnetic field that coil produces is spacing mobile, open and close intercommunicating pore by moving of control spool, thus control valve body import and outlet be communicated with or open close.
Be arranged because inlet valve and waste water valve independently divide, a water purifier need dispose two independent valve, and whole cost is higher, and connects comparatively complexity, and installation takes up space bigger, makes overall structure compact inadequately.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of solenoid valve that is used for the washing and filtering device at above-mentioned prior art present situation, and it unites two into one inlet valve and waste water valve, saves materials such as coil, reduce cost, and save space easy for installation.
The utility model solves the problems of the technologies described above the technological scheme that is adopted: this is used for the solenoid valve of washing and filtering device, it is characterized in that: comprise left valve barrel, right valve barrel, be horizontally installed on left spool and the right spool between left valve barrel and the right valve barrel, the left coil that is separately positioned on left spool and right spool periphery and right coil, the coil case that is set in left coil and right coil periphery and yoke;
Wherein, each valve body has import, outlet up and down, and the middle part of valve body is provided with the intercommunicating pore of a connection import, outlet, and the end of this intercommunicating pore just in time head with spool is relative;
Described left spool and right spool adopt magnetic conductive metal, between left spool and right spool, be provided with an armature, each spool can the left and right sides is spacing between the end of the intercommunicating pore of correspondence and armature under the effect of corresponding coil moving, and, also be arranged with a spring in each spool periphery, between the head that the two ends of this spring are against corresponding spool respectively and the inwall of coil case and make spool have the trend that resets to corresponding intercommunicating pore direction;
And described coil case is connected between left valve barrel and the right valve barrel.
During real work, behind the right coil electricity, right spool is moved to the direction (promptly left) away from corresponding intercommunicating pore, right spool and armature adhesive, at this moment, the import and export conducting of right valve barrel; The left coil energising makes left spool move to the direction (promptly to the right) away from corresponding intercommunicating pore, left spool and armature adhesive, at this moment, the import and export conducting of left valve barrel.
During practical application, left valve barrel can be used as inlet valve, and right valve barrel can be used as the waste water valve.When proper functioning, only need to open the inlet valve on the left side, this moment left spool and armature adhesive; When needs wash, need open inlet valve and waste water valve simultaneously, at this moment the spool of the right and left while and armature adhesive.Because the waste water valve is being in the inlet valve back along the flow direction, the waste water valve is in low hydraulic pressure environment after inlet valve is closed, add and open behind the inlet valve flow that so will open the waste water valve, the right spool of adhesive is the less right coil of needs only also to the wastewater valve delay phenomenon.In addition, in when flushing, the operating current that only needs moment is by right coil, make the right coil and armature adhesive of waste water valve after, provide maintenance magnetic field by left coil, can reduce the quantity that is provided with of right coil, simultaneously, also reduced the cost of control module drive circuit.
Compact more for the internal structure that makes solenoid valve, rationally, described yoke can comprise U type left side yoke and the right yoke of U type, wherein, the vertical part of the left and right yoke of U type is wrapped in respectively outside the respective coil, and the lateral part of the left and right yoke of U type then is positioned at a side of corresponding coil.
Can stop up the end of intercommunicating pore preferably for the head that makes spool, can be embedded with a rubber stopper in the head of described spool, utilize rubber stopper to have elastic packing effect preferably, make the head of spool when frequent collision intercommunicating pore end, intercommunicating pore is closed by the rubber stopper that is embedded.
As further improvement, described right spool can cross setting one central penetration hole, and the rubber stopper that is positioned at right spool head also has small through hole, and the central penetration hole of this right side spool and the small through hole of rubber stopper connect, and form a relief hole that communicates with corresponding intercommunicating pore; So, do spacingly rapidly when mobile at right spool, current can be from this relief hole turnover, thereby can remove the dirt that is bonded at the rubber stopper end; And this relief hole makes rubber stopper have expansion and contractility preferably, also can regulate the pressure in the filter core container in the filtrating equipment, keeps the steady of filtrating equipment internal pressure, and is very practical.
For making reliable more, the sealing of being connected of coil case and left and right sides valve body, described left valve barrel, right valve barrel can be extended with a circle connecting wall respectively to central authorities, and the two ends of described coil case just link to each other with the connecting wall of left and right valve body respectively.This coil case can also adopt the plastic injection-moulded alternate manner that waits to link to each other with left and right sides valve body.
Compared with prior art, advantage of the present utility model is: by the design of two valve bodies, two spools and two coils, inlet valve and waste water valve are united two into one, left valve barrel wherein can be used as inlet valve, and right valve barrel can be used as the waste water valve; Simultaneously, can reduce the quantity that is provided with of right coil, save material, reduce cost, and solenoid valve is easy for installation, it is less to take up space, and makes device compact overall structure, rationally.
