The present invention is further illustrated below in conjunction with accompanying drawing.
Present embodiment: a kind of manufacture method of small-sized Proportional valve of control flow rate comprises:
The coiling step is used for electric lead is taken turns 41 around line, and the electric lead two end part is positioned two haptic elements 411 of line wheel 41;
Positioning step is used for having the line of electric lead to take turns 41 fixedly sleeved stationary axle 22 in the metal side ring solderless wrapped connection, simultaneously two conductive poles 11 that are connected to loam cake 1 is extended at the two end part of electric lead, to be connected to external power;
Installation step is used to assemble each component.
A kind of small-sized Proportional valve of control flow rate shown in Fig. 1,2,3,4, comprises loam cake 1, base 2, Flexible Reset body 3, heart body 4 and fixing device 5.
As shown in Figure 1, 2, loam cake 1 has upper perimeter wall 14 and upper wall 15, and upper perimeter wall 14 is formed by the outer periphery extension downwards of upper wall 15.The lower surface center of upper perimeter wall 14 is provided with positioning block, and the center of the upper surface of upper perimeter wall 14 is provided with locating column 13.Other is provided with vent 131, and it wears the center of positioning block, upper perimeter wall 14 and locating column 13.The upper perimeter wall 14 lower end inner circumference edges of loam cake 1 are set as positioning step on.Upper perimeter wall 14 offers two grafting through holes, and coupling has two conductive poles 11 in addition, and conductive pole 11 sealably is plugged in the grafting through hole, and two conductive poles of conductive attachment, 11, two conductive poles 11 can external external power respectively for two end lines of coil 43.The upper-end surface of loam cake 1 has two parallel locating slots 12.
Base 2 is the metal side ring.The metal side ring has lower peripheral wall 23 and diapire 24, and lower peripheral wall 23 is extended upward by the periphery of diapire 24 and forms.Lower peripheral wall 23 inner side surfaces of metal side ring are adsorbed with magnet 21, and magnet 21 is made up of three blocks of magnet, and each magnet is circular shape, and three blocks of magnet constitute the shape of a similar cylinder, or as a whole cylinder-shaped magnet.The center of diapire 24 is provided with stationary axle 22, the dead in line of the axis of stationary axle 22 and metal side ring.The upper end outer periphery of the lower peripheral wall 23 of metal side ring are set as down positioning step.The height of magnet 21 and stationary axle 22 is all less than the height of lower peripheral wall 23.
The diameter of upper perimeter wall 15 is identical with the diameter of lower peripheral wall 23.Following positioning step and last positioning step are structurally suitable.The last positioning step fixed card of loam cake 1 is connected on the following positioning step of base 2.
Heart body 4 comprises line wheel 41, soft pad 42 and coil 43.Soft pad 42 has the rubber pad of coarse processing for the surface.Line wheel 41 has a cylindrical hole; Soft pad 42 is fixed at line and takes turns 41 upper-end surfaces, but the cylindrical hole of blockade line wheel 41.The online wheel of electric lead solderless wrapped connection constitutes coil 43 on 41.The upper-end surface of line wheel 41 is provided with two haptic elements 411, and the two end part of coil 43 are positioned two haptic elements 411, and extend respectively at two end part and two conductive poles of difference conductive attachment, 11, two conductive poles, 11 external external powers, is connected in extraneous power supply so coil 43 can conduct electricity.Line wheel 41 is socketed on the stationary axle 22 by the cylindrical hole in it; Coil 43 is between stationary axle 22 and magnet 21.Line is taken turns 41 upper-end surfaces and is offered a location groove.
The vent 131 of rubber seal loam cake 1.Produce attraction force, phase repulsive force mutually by between coil 43 energising back and the magnet 21, and the elastic force of spring cooperates the control rubber pad to move up and down, so control control flow rate small-sized Proportional valve close or open-minded.
Flexible Reset body 3 is awl property Returnning spring.Flexible Reset body 3 is taken turns between 41 upper-end surfaces between the lower surface and the line of the upper wall 14 of loam cake 1, and socket positioning block and soft pad 42.The bottom of Flexible Reset body 3 is positioned at positioning groove.
Fixing device 5 is two " door " word clamping button 51, and it all has a location cross bar 511, two location montants 512 and two location fasteners 513.The two end part of two the fixedly connected location of location montant 512 difference cross bars 511.Two location fasteners 513 are respectively two location montants 512 and form to close direction inward direction extension.Two distances of locating between the montant 52 equal the diameter of upper perimeter wall 15; The lower peripheral wall 23 that the length of location montant 52 equals the upper perimeter wall 25 of loam cake 1 and the base 2 later axial line distance of closing.
Two location cross bars 511 are positioned respectively in the locating slot 12; Location montant 512 is abutted against the upper perimeter wall of loam cake 1 and the lower peripheral wall of base 2; Location fastener 513 is against the bottom surface of the diapire that is connected to base 2.
Loam cake is fixedly connected on the upper-end surface of base by fixing device 5.Fixing device 5 also can be the fixing device of the fixed fixing device of card ditch, binder bonding way or the fixing device that the overhead kick button hook connects mode.
Its working procedure is as follows: behind the electric current that coil 43 receives from external power by conductive pole 11, coil 43 produces a magnetic force, produces a suction or a phase repulsive force mutually with magnet 21, if heart body 4 then be a repulsive force to extrapolation, if inwardly suction then is an attraction force; The elastic force of attraction force, phase repulsive force and spring cooperates by producing mutually between coil 43 energising back and the magnet 21, control rubber pad and move up and down, and then the control ratio valve close or open-minded; And between this action, because the cylindrical hole socket stationary axle 22 of the line of heart body wheel 41, prevent from that the heart body from producing to rock, and then improve the precision of control.
As shown in Figure 5, conduit 6 connects the small-sized Proportional valve 10 of pressure transducer 7, air bag 8, group Pu 9 and control flow rate, when inflate in group Pu 9, Proportional valve 10 is subjected to the control of circuit board 100 and cuts out, this moment air bag 8 gassies, group Pu 9 stops inflation, because conduit 6 is connected with air bag 8, its pressure equates, via pressure transducer 7 induction conduits 6 pressure inside,, then import a signal into to circuit board 100 via a RCA 101 if pressure is excessive, circuit board 100 control ratio valves 10 lose heart gradually, make the pressure of air bag 8 reach required value.
The above, only for preferred embodiment of the present invention, so can not limit scope of the invention process with this, i.e. the equivalence of doing according to the present patent application claim and description changes and modification, all should still belong in the scope that patent of the present invention contains.
