Description of the drawings
Fig. 1 is the structure diagram of the present embodiment sliding sleeve switch；
Specific embodiment
The present invention from following embodiments limitation, can technique according to the invention scheme and actual conditions determine specifically
Embodiment.
In the present invention, for ease of description, the description of the relative position relation of each component 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 come definite.
With reference to embodiment and attached 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 both ends of pipe are fixedly connected respectively with top connection 1 and lower contact 2, and through hole 5 is provided on the side wall of outer tube, and sliding sleeve 4 is set in
The inside of the outer tube, sliding sleeve switch further include driving device (61,62) and pressure sensor 7, and driving device is connected with sliding sleeve,
It is 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 previously mentioned, existing oil well sliding bush apparatus needs dedicated switching tools, switch is complicated.It is provided in this embodiment
Sliding sleeve switch slides over sliding up and down in outer tube by being arranged on the driving device inside sliding sleeve switch to drive, and realizes logical
The exposing and closing in hole improve work effect consequently facilitating the opening and closing of the circulation passage of liquid, save the work period
Rate improves production cost.Further, be arranged on through hole side surface pressure sensor can be used for detect through-hole surfaces bear
Pressure value, therefore by monitoring pressure value, the circulation status of circulation passage can be monitored, ensure that the stabilization work of sliding sleeve switch
Make.
Further, the drive signal of driving device is adjustable.Since the drive signal of driving device is adjustable, so as to adjust sliding sleeve
Movement degree, so as to adjust the exposing degree of through hole (that is, be open), realize that the flow of sliding sleeve switch is adjustable.
In actual use, due to situation limit, by drive signal control through hole actual exposing degree often and
Target is exposed degree and is had differences, and causes flow control that can not accomplish accurately.
Therefore in order to improve the degree of regulation of flow, sliding sleeve switch further includes control device, control device and pressure sensing
Device is connected with driving device, and control device is used to determine the drive signal of driving device according to the pressure value that pressure sensor detects
To drive the movement of sliding sleeve switch and then adjust the exposing degree of 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 opening area of through hole indirectly, and opening area further determines that the flow of sliding sleeve switch is big
It is small, therefore can will reflect that the pressure value of the pressure sensor detection of through hole actual aperture area feeds back to control dress
It puts, control device determines the difference of actual aperture area and target opening area so as to adjust driving device according to the pressure value
Drive signal realizes high-precision flow-rate adjustment.
More specifically, control device includes：
Pressure flow database, for storing the correspondence of the through-hole side surface pressing value and flow；

Determination unit, for determining drive signal according to the difference.
Wherein pressure flow database can be by testing measured in advance, and control device is a central processing unit (CPU) or micro-
Processing unit (MCU).
Preferably, pressure sensor is corrosion resistant pressure sensor, is prevented since long-time is caused by liquid corrosion
Failure, improves service life.
The structure of driving unit is further described below, driving unit includes pressing unit and shift cells up, respectively
For driving moving down and moving up for sliding sleeve.Further, pressing unit for hydraulic cylinder and is arranged in hydraulic cylinder
Piston 61, piston is connected with sliding sleeve, and shift cells up is spring 62, and one end of the spring is connected with sliding sleeve, and the other end is fixed on
In lower contact.
During use, by piston sliding sleeve is driven to move downward, so as to which the through hole of outer tube be exposed, realize circulation passage
Opening, piston apply power remain unchanged, realize circulation passage opening state maintenance.Sliding sleeve moves upwards if necessary,
The power that piston applies removes, by the reset response of spring, so as to which sliding sleeve be promoted to move upwards.
