Description
Technical Field
The invention relates to the technical field of electrorheological valves, in particular to an array electrorheological valve with a pre-buried runner and a processing method thereof.
Background
The electrorheological valve is a valve made by utilizing the property that electrorheological fluid can be reversibly converted from liquid state to quasi-solid state under the control of an external electric field. The working principle is as follows: in the absence of applied electric field control (zero field), the electrorheological fluid transmits hydraulic pressure in fluid form; when a control electric field is applied to the electrorheological fluid, the electrorheological fluid is converted into a solid-like state, a certain yield stress is presented, the yield stress and the field intensity of the applied external electric field are positively correlated, when the field intensity of the external electric field exceeds a certain threshold value, the electrorheological valve composed of the control electrode and the electrorheological fluid therebetween presents a certain valve pressure drop, the hydraulic pressure smaller than the valve pressure drop can be blocked, and the fluid state at the other end of the valve is not disturbed.
The array electrorheological valve comprises a plurality of isolation plates and electrode assemblies, wherein the electrode assemblies are arranged on two sides of the isolation plates by taking the isolation plates as the centers, and two adjacent isolation plates and the electrode assemblies on two sides jointly enclose a valve channel which allows electrorheological fluid to flow, as shown in the publication No. CN 113327488A. The structure can be processed by adopting a batch type industrial production process, and has the advantages of low processing cost and low price. During assembly, two end faces of the array electrorheological valve, which are perpendicular to the direction of the flow channel, are required to be used as sealing surfaces to be in sealing fit with other parts. The sealing surface needs to be processed for the second time to ensure flatness, thereby meeting the sealing performance requirement. The secondary processing is most commonly performed in two modes of gluing leveling and pressure sealing: coating a self-leveling adhesive layer on a sealing surface to enable the self-leveling adhesive layer to form a plane in a self-leveling manner, and ensuring tightness by matching the plane with other parts; the pressure sealing is to add a gasket or an elastic piece on the sealing surface, and to put other parts to be matched on the gasket or the elastic piece to realize the sealing by pressure.
In the existing array electrorheological valve, because the inlet and the outlet of the flow channel are exposed, if the secondary processing is carried out in a gluing and leveling mode, the gelatinous material easily enters the flow channel to change the sectional area and even block the flow channel, so the secondary processing of the sealing surface is not suitable for being completed in a gluing and leveling mode, and only can be carried out in a pressure sealing mode. The pressure seal has higher requirements on the flatness of the sealing surface, and because if the flatness of the combined surface is poor, the sealing pressure on the periphery of the valve flow passage opening is uneven, and hidden danger is brought to the use durability of the device. Therefore, when pressure sealing is adopted, the flatness of the sealing surface needs to be ensured, and the flatness of the sealing surface is influenced by the processing precision of the workpiece, if the requirements of the sealing performance of the cavity are met, the processing precision of all the workpieces needs to be strictly controlled. The processing precision of the workpiece is required to be higher, the cost is increased, and the advantage of cost reduction brought by the process is weakened.

In addition, as the flatness of the sealing surface is ensured by the self-leveling adhesive layer, the processing precision requirements of the isolation plate 2 and the electrode plate 1 are reduced, and the processing cost is reduced.
As an improvement scheme: in step S1, two first mounting holes 23 are formed on the board surface of the isolation board 2; in step S2, two second mounting holes 11 are first formed on the plate surface of the electrode plate 1, then the separator 2 is stacked with the electrode plate 1, the first mounting holes 23 and the second mounting holes 11 are aligned, and finally the positioning members are inserted into the first mounting holes 23 and the second mounting holes 11.

For a clearer understanding of the structure of the electrorheological valve of the present invention, a specific application thereof to the braille electronic book is described in detail below.
The bump related structure of the existing Braille electronic book is as follows:
Referring to fig. 5, the electrorheological fluid chamber comprises a braille convex point 3, an electrorheological fluid chamber body 4, an electrorheological fluid flow channel 5, a control electrode 6 and a piston 7, wherein the control electrode 6 is provided with an anode and a cathode, the anode and the cathode are arranged in parallel, electrorheological fluid only flows through the middle of the control electrode 6, and the braille convex point 3 is communicated with the electrorheological fluid chamber body 4 through the electrorheological fluid flow channel 5. When the electrorheological valve does not apply a control electric field, electrorheological fluid in the electrorheological fluid cavity 4 can drive the Braille salient point 3 to move through the electrorheological fluid flow channel 5 under the action of the piston 7. When the piston 7 moves rightwards and the electrorheological fluid cavity 4 generates negative pressure, the braille convex point 3 drops; otherwise, the braille convex point 3 is lifted. That is, when the control electric field is not applied, the state of the braille bump 3 is changed by the movement of the piston 7. When a control electric field is applied, electrorheological fluid in the electrorheological fluid flow channel 5 is converted into a quasi-solid state, the valve presents a certain valve pressure drop, and at the moment, when the pressure generated by the piston 7 in the electrorheological fluid cavity 4 is smaller than the valve pressure drop, the pressure of a small cavity connected with the Braille salient point 3 at the other end of the valve is not changed, and the state of the Braille salient point 3 is not changed. Obviously, by applying or not applying an externally applied control electric field, independent control of the display state of the braille convex point 3 can be realized. When in use, the blind person acquires the braille information by touching the braille convex points 3, and reading is completed.
The application of the array electrorheological valve in the Braille electronic book is as follows:
the runner of the invention is the electrorheological fluid runner 5, all the salient points are arranged on a layered structure during assembly, and the layered structure is hermetically connected to one sealing surface of the valve of the invention, so that the salient points are in one-to-one correspondence and are communicated with the runner; the electrorheological fluid cavity 4 is connected on the other sealing surface of the valve in a sealing way, so that the electrorheological fluid cavity 4 is communicated with all the flow channels.
It is apparent that the above examples are given by way of illustration only and are not limiting of the embodiments. Other variations or modifications of the above teachings will be apparent to those of ordinary skill in the art. It is not necessary here nor is it exhaustive of all embodiments. While still being apparent from variations or modifications that may be made by those skilled in the art are within the scope of the invention.
