In the time that rotating core 400 rotates, medium can flow into rotating core 400 by passage,And flow in pressure chamber through rotating core 400, medium can promote spool 200 along pressureMove in chamber, makes import and outlet conducting.
Preferably, the quantity of above-mentioned valve gap 300 is two, and two valve gaps 300 are established respectivelyBe placed in the two ends of valve body 100, on two valve gaps 300, be provided with rotating core 400,Each rotating core 400 can be realized spool 200 single-way movings, can make medium promote spool 200Between two rotating cores 400, move back and forth, guarantee reversal valve is normally worked, and has improvedOperating efficiency.
Further, above-mentioned import comprises respectively the import P110 and the import that communicate with passageT120, outlet comprises the commutation mouth A130 that communicates with passage and a commutation mouthful B140, at the beginning ofUnder beginning state, spool 200 can block import P110 and make import T120 respectively with changeCommunicate to mouth A130 and a commutation mouthful B140, reversal valve quits work.
In the time that rotation is arranged at the rotating core 400 in valve body 100 left sides, medium can be by logicalRoad flows into this rotating core 400 and flows in pressure chamber by this rotating core 400, fromAxially move right along valve body 100 and medium can promote spool 200, make import P110Communicate with a commutation mouthful A130 and import T120 is communicated with a commutation mouthful B140, thereby realizingA commutation mouthful A130 normally work.
In the time that rotation is arranged at the rotating core 400 on valve body 100 right sides, medium can be by logicalRoad flows into this rotating core 400 and flows in pressure chamber by this rotating core 400, fromAxially be moved to the left along valve body 100 and medium can promote spool 200, make import P110Communicate with a commutation mouthful B140 and import T120 is communicated with a commutation mouthful A130, thereby realizingA commutation mouthful B140 normally work.
In use, two rotating cores 400 can be realized medium and flow into commutation mouthfulThe switching of A130 or commutation mouthful B140, has ensured the normal work of reversal valve, simultaneously logicalCrossing circumferential rotation of rotating core 400 makes medium promotion spool 200 axial along valve body 100Mobile, move axially and directly promote spool 200 by magnetic valve in replacement prior art,Reduce the power consumption of the normal work of magnetic valve, also avoided due to solenoid valve failure simultaneouslyCause the generation of spool 200 stuck phenomena, improved operating efficiency and the work of reversal valveLife-span.
Stretch out and be formed with installation portion 410 at the two ends of spool 200, at installation portion 410On be arranged with the elastic component 500 resetting for spool 200, on valve gap 300, offerThe mounting groove corresponding with elastic component 500, the two ends of elastic component 500 are resisted against respectively spool200 and mounting groove on, elastic component 500 be arranged so that energy in the time that reversal valve quits workPromote spool 200 and return back to initial position, ensured the normal work of reversal valve, improveThe operating efficiency of reversal valve.
Above-mentioned rotating core 400 comprises installation portion 410 and rotation section 420, installation portion 410Be arranged on valve gap 300, above-mentioned rotation section 420 is fixed on installation portion 410 also outsideStretch out valve gap 300, on the outer surface of installation portion 410, offer the first cannelure 411Communicate with a commutation mouthful P with the second cannelure 412, the first cannelures 411, the second annularGroove 412 communicates with commutation mouthful A130 and pressure chamber respectively, on valve gap 300, offers useIn UNICOM's groove of the first cannelure 411 and the second cannelure 412 conductings.
Preferably, offer the first link slot 413, second at installation portion 410 outer surfacesLink slot 414 and the 3rd link slot 415, described the first link slot 413 and first ringShape groove 411 communicates, and described the second link slot 414 and the 3rd link slot 415 are all with secondCannelure 412 communicates, and described UNICOM groove energy conducting the first link slot 413 is connected with secondGroove 414, the medium in described import T120 is directed in the 3rd link slot 415, and logicalCrossing the 3rd link slot 415 flows in the second cannelure 412.
Under original state, the passage that import T120 communicates and the 3rd link slot 415 misplace,Thereby the medium in import T120 can not be directed in the second cannelure 412, and joinGroove can make the first cannelure 411 and the second cannelure 412 UNICOMs, in import P110Medium can flow into the first cannelure 411 of two installation portions 410 and enter by UNICOM's concentrated flowTo the second cannelure 412, final medium is directed in the pressure chamber of both sides, thus both sidesMedium thrust that spool 200 is produced cancel out each other, thereby spool 200 is staticMoving.
In the time that the rotation section 420 in left side drives installation portion 410 circumferentially to turn to certain angle,UNICOM's groove turns an angle and makes the first cannelure 411 and with respect to installation portion 410Second ring groove 412 is blocked, and the medium in import T120 can pass through the 3rd link slot 415Flow in the second cannelure 412 and be directed in pressure chamber, but due to import T120The pressure of interior medium is less than the pressure of medium in import P110, thus right side in pressure chamberPressure be greater than the pressure in left side in pressure chamber, thereby spool 200 along pressure chamber axially toMove left.
In the time that the rotation section 420 on right side drives installation portion 410 circumferentially to turn to certain angle,UNICOM's groove turns an angle and makes the first cannelure 411 and with respect to installation portion 410Second ring groove 412 is blocked, and the medium in import T120 can pass through the 3rd link slot 415Flow in the second cannelure 412 and be directed in pressure chamber, but due to import T120The pressure of interior medium is less than the pressure of medium in import P110, thus left side in pressure chamberPressure be greater than the pressure on right side in pressure chamber, thereby spool 200 along pressure chamber axially toMove right.
Preferably, be respectively arranged with magnetic valve at the two ends of valve gap 300, above-mentioned portion and electricityMagnet valve is connected, and can drive rotation section 420 circumferentially to rotate in the time that magnetic valve is switched on, and is usingIn process, two magnetic valve alternate conduction can realize medium and promote spool 200 along valve body100 move back and forth, and have ensured the normal work of reversal valve.
On rotation section 420, run through and be provided with gag lever post 600, on valve gap 300, arrangeLimited location post 610, gag lever post 600 can circumferentially rotate between adjacent two limited posts 610,Arranging of limited post 610 improved rotation section 420 rotation precision, avoids due to rotation section420 rotation precision generation error and affect normally the work generation of phenomenon of reversal valve, carriesThe high operating efficiency of this reversal valve.
Specific embodiment described herein is only for example to the utility model spiritExplanation. The utility model person of ordinary skill in the field can be to described concreteEmbodiment makes various amendments or supplements or adopt similar mode to substitute, but notCan depart from spirit of the present utility model or surmount the defined model of appended claimsEnclose.
