Description
Technical field
The utility model relates to a kind of magnetic control shape memory alloy high-speed switch valve, belongs to hydraulic transmission technology field.
Background technique
The combination of hydraulics and Computer Control Technology facilitates the development of hydraulic proportion technology, servo techniques and digital hydraulic technology, occurred servovalve, Proportional valve and high-speed switch valve, they have been widely used in the industrial departments such as machine-building, communications and transportation, aviation, navigation, military affairs.But the structure of high-speed switch valve and function improve servovalve and Proportional valve shortcoming existing separately, the shortcomings such as the contamination resistance as servovalve is poor, the control accuracy of Proportional valve is not high.Because of the height of high-speed switch valve respond, highi degree of accuracy and excellent static and dynamic performance make it be subject to concern and the research of people, and make hydraulics enter new field.Electrohydraulic control can realize higher operating accuracy, but causes processing request high because of complex structure, and exist contamination resistance difference, expensive, be not directly connected with computer and the shortcoming such as control.And the relative servovalve contamination resistance of proportional digital valve is comparatively strong, price is also comparatively cheap, but control accuracy is low, and needs digital to analog converter just can be connected with computer.Servovalve and Proportional valve all can not meet that both structures are simple, low price, control accuracy are high, contamination resistance is strong, the direct requirement do not needed by digital-to-analog conversion etc. that is connected with computer simultaneously.
Summary of the invention
The purpose of this utility model is to provide a kind of magnetic control shape memory alloy high-speed switch valve, to solve the problems such as existing high-speed switch valve complex structure, controllable precision is low, control flow is little, response frequency is slow.
The utility model realizes by following technological scheme: a kind of magnetic control shape memory alloy high-speed switch valve, comprises driver 1, end cap 2, combination seal 3, valve body 4, valve pocket locating stud 5, spool 6, valve pocket 7, seal ring 8, coaxial combination sealing 9; Spool 6 is arranged in valve pocket 7 by coaxial combination sealing 9, valve pocket 7 is arranged in valve body 4 by seal ring 8, end cap 2 is arranged on spool 6 two ends by combination seal 3, and be connected with valve pocket 7 by valve pocket locating stud 5, driver 1 is arranged on end cap 2 the other end, and spool 6 is Symmetric Cone valve core structure.
A kind of working principle of magnetic control shape memory alloy high-speed switch valve is: driver 1 adopts novel intelligent material magnetic control memory alloy, when after the energising of right side magnetic control memory alloy driver 1, magnetic control memory alloy material elongation promotes spool 6 and is moved to the left the formation linear sealing until left cone valve contacts with valve pocket 7, right cone mouth is opened, left cone mouth is closed, now A mouth is communicated with T mouth, and disconnects with P mouth; When after the energising of left side magnetic control memory alloy driver 1, magnetic control memory alloy material elongation directly promotes spool 6 and to move right the formation linear sealing until right cone valve contacts with valve pocket 7, and left cone mouth is opened, and right cone mouth closedown, now A mouth is communicated with P mouth, disconnects with T mouth.When left and right two magnetic control memory alloy driver 1 no electric circuit, when namely not producing magnetic field, magnetic control memory alloy material does not stretch, and spool 6 stop motion, magnetic control memory alloy high-speed switch valve does not work.
The utility model has following beneficial effect:
1, adopt two-position three way formula high-speed switch valve, make valve body structure simple, be easy to manufacturing;
2, adopt symmetric double poppet spool valve structure, good sealing effect, easily reach few leakage or zero leakage, and spool stroke is short, is easy to realize switch, fast response time, and be conducive to the commutation of frequent switch;
3, driving mechanism adopts magnetic control memory alloy driver, and its output displacement and ouput force are all larger, do not need enlarger to amplify the displacement of output, can Direct driver spool, greatly can simplify the structure of high-speed switch valve;
4, driver adopts magnetic control memory alloy material, can extend rapidly or stretch under Magnetic control within the Millisecond time, can realize the response of high-speed switch valve snap switch.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is valve core structure schematic diagram of the present utility model.
In figure, each label is: 1: driver, 2: end cap, 3: combination seal, 4: valve body, 5: valve pocket locating stud, 6: spool, 7: valve pocket, 8: seal ring, 9: coaxial combination seals.
Embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail, but content of the present utility model is not limited to described scope.
Embodiment 1: as shown in Figure 1-2, a kind of magnetic control shape memory alloy high-speed switch valve, comprises driver 1, end cap 2, combination seal 3, valve body 4, valve pocket locating stud 5, spool 6, valve pocket 7, seal ring 8, coaxial combination sealing 9; Spool 6 is arranged in valve pocket 7 by coaxial combination sealing 9, valve pocket 7 is arranged in valve body 4 by seal ring 8, end cap 2 is arranged on spool 6 two ends by combination seal 3, and be connected with valve pocket 7 by valve pocket locating stud 5, driver 1 is arranged on end cap 2 the other end, and spool 6 is Symmetric Cone valve core structure.
