Embodiment
In conjunction with the accompanying drawings and embodiments the utility model is described in further detail now, these accompanying drawings are the schematic diagram of simplification, and basic structure of the present utility model is only described in a schematic way, and therefore it only shows the formation relevant with the utility model.
As shown in Figures 1 to 4, a kind of mangetic core assembly of three-position three-way valve, comprise and being made of plastics, inside has the cylindrical body 10 of the first axial flow channel 50, body 10 one end are removably socketed with the first annular lining 20 of plastics, one-body molded on body 10 the other ends have an annular plastics lug boss 40, on body 10, between the first lining 20 and lug boss 40, be arranged with the second annular lining 30 of plastics, under the parcel of valve, between the second lining 30 and the first lining 20, form the second flow channel 60, between lug boss 40 and the second lining 30, form the 3rd flow channel 70.In the time that this spool moves in valve, can change corresponding flow channel, to allow water by just the washing of purifier, backwash passage and effluent is purified water by purification channel.
In the utility model, on body 10 ends, being circumferentially with several blocks the first lining 20 and prevents its axially movable slope 11.Concrete, be circumferentially with several uniform projections 21 at the first lining 20 inwalls, between adjacent two projections 21, form the breach 22 axially passing respectively for each slope 11, as preferred implementation of the present utility model, four slopes 11 are evenly set on body 10 ends, at the first lining 20 inwalls, 21, four projections 21 of four projections are set and form between any two four breach 22, the size of four breach 22 is mated with slope 11, so that each slope 11 can be passed respectively from each breach 22.When use, each breach 22 on the first lining 20 is aimed to each slope 11 on body 10 axially to wearing, each slope 11 is passed respectively from each breach 21, the first lining 20 again rotates in a circumferential direction, staggered in the position on each breach 22 relative slopes 11, so, can avoid first lining 20 landing from body 10.
Further, between body 10 and the first lining 20 inwalls, support by the bearing pin radially arranging, by the positioning groove 12 of the symmetrical placement bearing pin in two positions is circumferentially set on body 10 end outer walls, the fixed hole 23 of the symmetrical locking bearing pin in two positions is circumferentially correspondingly set on the first lining 20 inwalls.Utilize bearing pin supporting body 10 and the first lining 20, can prevent that the first lining 20 from moving axially on body 10, because bearing pin can provide support force radially to the first lining 20 diametrically, avoid the first lining 20 to move axially.
Preferably, on body 10 ends, be positioned at positioning groove 12 rear sides and be provided with at least one and support the bulge loop 13 of the first lining 20 inwalls.In the time that the first lining 20 is enclosed within to body 10 end, rely on bulge loop 13 to support the first lining 20, preventing from installing the first lining 20, the first linings 20 in the situation that not supporting can produce, and affects the installation of bearing pin.In the utility model, at the rear side of positioning groove 12, two parallel bulge loops 13 are set, utilize two bulge loops 13 to support better the first lining 20.
For convenience of using, can four marks 18 be circumferentially set equably at the rear side of bulge loop 13, in a side of the first lining 20, the side that two grooves 24 and two projection 25, two grooves 24 and two projections 25 stagger respectively, are circumferentially evenly distributed in the first lining 20 is also correspondingly set.In the time that the first lining 20 is installed, rotating the first lining 20 staggers breach 22 and slope 11, when rotation, groove 24 on the first lining 20 or projection 25 are aimed to correspondingly mark 18, just washing and backwash state of the mark 18 corresponding water purifiers at diverse location place, so, in spool is installed to valve, can the residing working state of clear and definite spool.
In the utility model, the second lining 30 of annular rotates and is not set in slidably on body 10, the first bulge loop 14 and the second bulge loop 15 specifically can be set on body 10, the second lining 30 is fastened in the annular groove 16 forming between the first bulge loop 14 and the second bulge loop 15, circumferentially establishes several at the second lining 30 inwalls and prevent the relative body 10 of the second lining 30 the first fixture block 31 and the second fixture block 32 in axial sliding.The second lining 30 is snapped in annular groove 16, can make the second lining 30 rotate relative to body 10, when spool moves in valve, because the second lining 30 is to flexibly connect with body 10, can not destroy rigidly the second lining 30; Guarantee that by the first fixture block 31 and the second fixture block 32 the second lining 30 can not follow spool and move, avoid flow channel entanglement.
Preferably, one side of the first fixture block 31 can be resisted against on the madial wall of the first bulge loop 14, one side of the second fixture block 32 is resisted against on the madial wall of the second bulge loop 15, utilizes the abutment action of the first fixture block 31 and the second fixture block 32, guarantee the second lining 30 not relatively body 10 slide axially.
Further, the cross section of the first fixture block 31 is rectangular, and the thickness of the first fixture block 31 is less than the thickness of the first bulge loop 14, and so, the first fixture block 31 can not crossed the first bulge loop 14; The second fixture block 32 is wedge shape, and the side direction opposite side that the height of the second fixture block 32 is resisted against on the second bulge loop 15 from it successively decreases, and the second fixture block 32 height of being resisted against the side on the second bulge loop 15 is less than the height of the second bulge loop 15.The second fixture block 32 is set to wedge shape, be convenient to the second lining 30 and cross the second bulge loop 15 and snap onto in annular groove 16, and the height of second fixture block 32 one end is short in the edge of the second bulge loop 15, avoids the second lining 30 to skid off in annular groove 16.
Preferably, the arranged outside of the second bulge loop 15 can be transitted to the inclined-plane 17 in annular groove 16 for ease of the second fixture block 32.The second fixture block 32 of wedge shape can carry over inclined-plane 17 and enter in annular groove 16, and when both relatively move, frictional force is less, can like a cork the second lining 30 be snapped onto in annular groove 16.
In the utility model by the first lining 20 and the second lining 30 are removably set on the body 10 of spool, and the first lining 20 can be rotated and not slide relative to body 10 with the second lining 30, compare one-body molded on spool body 10 to the first lining 20 and the second lining 30, the thickness of the spool of plastics of the present utility model is controlled, and the spool face of plastics is smooth, better with the sealing of valve, while movement in valve, not yielding, can not cause flow channel entanglement; If lining is damaged, only need more resleeve, without changing whole spool body, greatly reduce cost.
Be enlightenment according to desirable embodiment of the present utility model above, by above-mentioned description, related personnel can, not departing from the scope of this model utility technological thought, carry out various change and amendment completely.The technical scope of this model utility is not limited to the content on specification, must determine technical scope according to claim scope.
