Brief description of the drawings
Fig. 1 is the structural representation of the present embodiment sliding sleeve switch；
Embodiment
The present invention is not limited by following embodiments, can technique according to the invention scheme and actual conditions it is specific to determine
Embodiment.
In the present invention, for the ease of description, the description of the relative position relation of each part is according to Figure of description 1
Butut mode be described, such as：The position relationship of forward and backward, upper and lower, left and right etc. is the cloth according to Figure of description 1
Figure direction is determined.
With reference to embodiment and accompanying drawing, the invention will be further described：
As shown in figure 1, the present embodiment provides a kind of sliding sleeve switch, including top connection 1, lower contact 2, outer tube 3, sliding sleeve 4, outside
The two ends of pipe are fixedly connected with top connection 1 and lower contact 2 respectively, and through hole 5 is provided with the side wall of outer tube, and sliding sleeve 4 is set in
The inside of the outer tube, sliding sleeve switch also includes drive device (61,62) and pressure sensor 7, and drive device is connected with sliding sleeve,
Slided up and down for driving to slide in outer tube, to expose or close the through hole, pressure sensor 7 is arranged on the through hole 5
Side surface, for detecting the pressure that through hole side surface is born.
As it was previously stated, existing oil well sliding bush apparatus needs special switching tools, switch is complicated.What the present embodiment was provided
Sliding sleeve switch, is driven by being arranged on the drive device inside sliding sleeve switch and slides over sliding up and down in outer tube, is realized logical
Exposing and closing consequently facilitating the opening and closing of the circulation passage of liquid, save the work period for hole, improves work effect
Rate, improves production cost.Further, the pressure sensor for being arranged on through hole side surface can be used for detecting that through-hole surfaces are born
Pressure value, therefore by monitoring pressure value, the circulation status of circulation passage can be monitored, it is ensured that the stable work of sliding sleeve switch
Make.
Further, the drive signal of drive device is adjustable.Because the drive signal of drive device is adjustable, so as to adjust sliding sleeve
Movement degree so that adjust through hole exposes degree (that is, opening), realize that the flow of sliding sleeve switch is adjustable.
In actual use, due to situation limit, the through hole controlled by drive signal actually expose degree often and
Target is exposed degree and had differences, and causes flow control can not accomplish accurate.
Therefore in order to improve the degree of regulation of flow, sliding sleeve switch also includes control device, control device and pressure sensing
Device is connected with drive device, and control device is used for the drive signal that the pressure value that is detected according to pressure sensor determines drive device
Expose degree to drive the motion of sliding sleeve switch and then adjust through hole.
Due in oil well oily total amount it is constant in the case of, via openings are bigger, and the pressure value that through-hole surfaces are born is smaller,
Therefore the pressure value reflects the aperture area of through hole indirectly, and aperture area further determines that the flow of sliding sleeve switch is big
It is small, therefore can be possible to reflect that the pressure value that the pressure sensor of through hole actual aperture area is detected feeds back to control dress
Put, control device determines the difference of actual aperture area and target aperture area so as to adjust drive device according to the pressure value
Drive signal, realizes high-precision Flow-rate adjustment.
More specifically, control device includes：
