embodiment.
Fig. 1 a is the connection theory structure schematic diagram of selector valve of the present invention, is the correlation of open communication on clear display fitting surface, exports end cap (2) and indicates with dotted line.In figure, 1 is thrust plate, and 2 for exporting end cap; S1 is the flow face of thrust plate (1), P is the upper fluid oil inlet passage of thrust plate (1), KP is the open communication of P channel on S1 face, T is the upper fluid drainback passage of thrust plate (1), KT is the open communication of T passage on S1 face, OX is the rotation centerline of thrust plate (1), S2 is for exporting the connected surface of end cap (2), A is for exporting end cap (2) upper first service aisle, KA is the opening of A channel on S2 face, B is for exporting end cap (2) upper second service aisle, and KB is the opening of channel B on S2 face; For to be slidably matched and S1 can rotate around OX axle between S1 face and S2 face; Can be found out by figure, be slidably matched on S1 and S1 face in commutation meta (also claim commutation initial position), throttling opening KP, KA, KT, KB circumferentially arrange successively centered by OX, when driving thrust plate (1) to rotate relative to output end cap (2), the direction of rotation can control oil-feed open communication KP, oil return open communication KT selects to carry out being communicated with the direction be namely interconnected between control KP and KT and KA and KB with service aisle open communication KA, KB or KB, KA respectively; Along with the continuous increase of angle of swing, 2 open communication start to be interconnected and constantly overlap, and connection area also will constantly increase, so the angle that control thrust plate (1) rotates can regulate the size being communicated with area.Thus by open communication, as long as rotary valve plate, the direction of fluid in A, channel B not only can be controlled, and the size of controllable flow rate, wherein sense of rotation will control the commutation of fluid, and angle of swing will control the size of flow.
Illustrate known by Fig. 1 a and principle, the surface of revolution that flow face S1 and connected surface S2 is is rotating center with OX axle, it can be not only plane, but also can be sphere, conical surface etc.; Its midplane processes the most simply, and quality of fit also the most easily realizes; Although sphere and conical surface have automatic centering function, effectively can improve the stability that thrust plate rotates, its requirement on machining accuracy can be higher.
The acceleration carrying out control load speed of general oil-feed flow in hydraulic system, controls the flow of load oil return with regard to needing when load-retarding.Valve of the present invention, by the shape of adjustment channel connection opening KP, KT, KA, KB, size and position, can realize oil-feed ratio throttling controlling functions and the oil return ratio throttling controlling functions of selector valve.As in fig 1 a, the two ends of oil-feed opening KP are provided with leg-of-mutton small flow throttling opening, when being communicated with, the connection area of KP and KA or KB will be less than KT and KB or KA, and such selector valve can carry out ratio throttling control to the circulation that P enters A, B service aisle.The connection of KP and KA or KB opening can certainly be made after a while in KT and BK or KA opening by adjustment aperture position, but the throttling opening of little trigonometric form can improve the proportional control precision of flow further; The shape of small flow throttling opening is exactly not necessarily triangle, can also be inclined-plane, rectangle or small semicircle etc.In like manner, when small flow throttling opening is located at the two ends of KT opening, just can realizes and improve the oil return adjustment stream of T and A or channel B; When small flow throttling opening is located at KA or KB two ends, oil-feed and the throttling of oil return ratio that just can realize A or channel B control.At this moment we can find selector valve of the present invention, can realize identical controlling functions in the amendment at different access portal positions; As shown in fig. 1b and fig. lc, they all can realize channel B oil-feed and meter out controls, but in figure 1 c, when B and T carries out large discharge meter out control, KA and KP carries out repairing by there being larger connection area.The design and devdlop of this alternatively bright open communication of the present invention of tool also will be more flexible, can meet the demand that different system is more complicated.
Valve of the present invention can form different selector valve Median Functions by adjustment open communication KP, the shape of KT, KA, KB, size with position; Median Function shown in Fig. 1 a, Fig. 1 b is O type and each channel enclosed of meta; Median Function shown in Fig. 1 d is that H type and meta P, A, B are communicated with T; Median Function shown in Fig. 1 e is that Y type and meta A, B are communicated with T; O type, H type and Y type are several Median Functions the most often used, and they can meet the demand of most system.
Fig. 2 a and Fig. 2 b is a kind of digital rotary proportional selector valve front section view of first preferred embodiment of the invention and H-H sectional drawing.In figure: 1. stepper motor, 7. pressure compensated piston, 8. spring, 9. fore bearing, the 10. rotating sealing device of thrust plate, 2. output end cap, 3. spool, 4. valve body, 5. rear bearing, 6. band speed reducer; Can be found out by figure, the structural feature of the present embodiment has: 1, flow face S1 and connected surface S2 are the plane vertical with axes O X and plane of rotation; 2, thrust plate (1) is installed on cartridge spool (3), and spool (3) is supported in the spool bore of valve body (4) by front and back bearings and also can rotates around center OX together with thrust plate; If when spool is higher with the quality of fit of spool bore certainly, fore bearing (9) can be cancelled; 3, spool is provided with the P channel mutually through with oil distribution casing and T passage and corresponding opening, keep being communicated with the P channel mouth on valve body (4) and T passway by the duct on valve body (4) and opening again, thus the open communication KP on thrust plate and open communication KT passage are kept mutually through with the P channel mouth on corresponding valve body and T passway; Between valve body and spool, P channel two ends can be provided with rotating sealing device (10), this lets out effectively reducing in valve body and reduces the quality of fit of spool and spool bore, when valve body and the gap coordinated of spool are very little, this sealing also can be cancelled; 4, in the present embodiment, there are 3 pressure compensated pistons (7) and 4 springs (8) axial force can be provided to thrust plate (1), the power of spring (8) can make Port Plate Pair (S1 and S2 sliding friction pair) form certain initial pressure, the active force of pressure compensated piston (7) and the pressure correlation of passage, Port Plate Pair can be made to maintain and to have certain pressure, as can be seen from Figure, pressure compensated piston (7) can compensate P, A and channel B pressure respectively, can ensure that letting out the little force of sliding friction that can make again in fitting surface is unlikely to excessive like this; 5, the rotary actuation of thrust plate and spool is completed by stepper motor (6), thus also makes the present embodiment selector valve become high performance numerical scale selector valve.
Figure 3 shows that the second preferred embodiment another kind of numerical scale selector valve front section view; The present embodiment is the same with first embodiment's principle; In figure, part name is identical with the first embodiment.Be with first embodiment's difference: 1. the function of thrust plate and spool is united two into one, become a part and thrust plate (1) (also can be spool (3)); 2. thrust plate (1) and spool bore are very little being slidably matched in highi degree of accuracy, gap, it and can not only make the leakage at P channel two ends smaller by the radial location of thrust plate (1), so just can cancel the fore bearing in the first embodiment and rotating sealing device; 3. in this example, pressure compensated piston (7) and spring (8) are located at the end of thrust plate (1), its effect is the same with the first example with principle, but structure and shape slightly different, pressure compensated piston (7) outer end planar S 4 that is direct by its piston shoes bottom surface and valve body (4) is slidably matched in the present embodiment, and directly by axial force transmission to valve body (4), thus also eliminate the rear bearing in the first embodiment.Relative to the first embodiment, the present embodiment structure more tightly short and thrust plate (1) rotational resistance also will be less; But thrust plate (1) is higher with the processing request of spool bore, and the internal leakage amount of valve body also will be larger than the first embodiment.Certainly the structure of the first embodiment and the structure of the second embodiment can be carried out different being combined to form new structural type, to meet the demand of system to selector valve function, performance in concrete enforcement.
The same with multiple directional control valve, multi-disc single-link valve also can be installed in parallel by selector valve of the present invention, is combined into multichannel rotary proportional selector valve and uses.Because the valve body structure of proportional reversing valve of the present invention is fairly simple, processing is also very convenient, so be also easy to process multiple spool bore at a valve body, installs multiple spool, the entirety realizing multiple selector valve is in parallel, thus forms overall multichannel rotary proportional selector valve.Relative to the structure be installed in parallel, overall structure has higher reliability.What Fig. 4 illustrated is overall 2 numerical scale selector valve front section views, and internal structure shown in figure is identical with the second preferred embodiment, can certainly adopt the first embodiment's or 2 structures combination; Also can find out from Fig. 4, it is feasible that valve body realizes more multi-joint parallel connection, and this will promote the flexibility of selector valve application greatly.
Selector valve of the present invention designs mainly for the feature of pump control open system comparative example selector valve, can meet large-capacity valve Ore-controlling Role particularly pump control open system to the requirement of high-performance proportional reversing valve.The foregoing is only present pre-ferred embodiments, non-ly therefore namely limit to the scope of the claims of the present invention, therefore the simple and easy change of such as doing by specification of the present invention and graphic content and equivalent transformation, all should be contained in the scope of the claims of the present invention.
