Specific embodiment
The present invention is described further below in conjunction with attached drawing:
The present embodiment includes injection well downhole flow regulator shell and the spool that is mounted in injection well downhole flow regulator shell, and the structure of injection well downhole flow regulator shell includes
From top to bottom pass sequentially through top connection 1, upper shell 2, mounting body 3, lower shell 4 and the lower contact 5 of threaded connection, the valve
Core is mounted in an axial hole in the mounting body 3, and the side of mounting body 3 and the spool were correspondingly arranged on
Fluid apertures 7.It is common structure in the prior art above, details are not described herein.
Innovation of the invention is, further includes the spool driver 24 with guide slide B.Pass through upper poppet-valve repeatedly
Core driver 24 switches over spool between switch two states, and operation technique is simple, and high reliablity, failure rate is low, holds
Easily implement.
Based on above-mentioned technical thought, spool and its related accessory structure are as follows:
Bushing pipe 6 is provided between the top connection 1 and mounting body 3, the upper and lower ends of upper bushing pipe 6 are inserted into respectively
In the seam allowance of 3 inside of top connection 1 and mounting body, the structure of the spool includes valve head 8 and valve rod 9, and valve head 8 and valve rod 9 are
Integral structure is cased with pressure cap 23, spring 20 and guide sleeve 22 on valve rod 9, and valve rod 9, spring 20 and guide sleeve 22 pass through pressure cap
23 are encapsulated in mounting body 3, and pressure cap 23 is threadedly attached in mounting body 3, and the valve head 8 is under the action of spring 20
It is kept away from the movement tendency of guide sleeve 22, guide slide A is provided on the inner wall of the guide sleeve 22, is consolidated on the valve rod 9
Surely it is provided with guide pin 21 corresponding with the guide slide A, the upper end of the valve rod 9 is fixed with a bending part 10, bending part
10 after the strip-shaped hole 11 of upper 6 side of bushing pipe from the inner wall of upper bushing pipe 6 by stretching out.
After the spool moves axially in reciprocal fashion, spool can under the cooperation of guide slide A and guide pin 21 in valve opening and
It closes and is switched between two states of valve.Concrete principle are as follows: as shown in figure 3, the left end of figure corresponds to the upper end of guide sleeve 22, figure
Right end corresponds to the lower end of guide sleeve 22, and the structure of the guide slide A includes dead point A12, dead point B13, dead point C14 and dead point
D15, when the guide pin 21 is located at dead point A12, spool is in valve position (position i.e. as shown in Figure 1), at this time upper poppet-valve
Core, guide pin 21 reach dead point B13 under the guidance of guide slide A, discharge spool, elastic force of the spool in the spring 20 at this time
Effect is lower to reach dead point C14, so that the switched on valve position of spool is again stepped up spool at this time, the guide pin 21 is being led
Dead point D15 is reached under to the guidance of slideway A, discharges spool at this time, and spool returns to dead point under the elastic force effect of the spring 20
A12, so that spool is switched to valve position.It should be noted that the guide sleeve 22 must be able to move back and forth in valve rod 9
It is freely rotated in the process with the variation of the axial position of guide pin 21, therefore, pressure cap 23 cannot thoroughly press guide sleeve 22
Tightly, it must assure that the smooth rotation of guide sleeve 22.In addition, can be further ensured that in the outer surface coating lubricating oil of guide sleeve 22
The smoothness of movement.
The effect of the spool driver 24 is: the bending part 10 is mentioned come on by spool driver 24, to drive valve
Core pumps, the final switching for realizing switching spool state.The whole cylindrical structure of spool driver 24, cylinder
Guide slide B is provided on face, the end of the bending part 10 is inserted in guide slide B and slides along guide slide B.
The structure of the guide slide B includes upper inlet 16, lower inlet 17, dead point E18 and dead point F19, spool driver
24 when shifting to the bending part 10 from upside, and the end of bending part 10 enters guide slide B from lower inlet 17, then slides in guiding
Dead point E18 is reached under the guidance of road B, at this time upper poppet-valve core derailing switch 24, end the drawing in guide slide B of the bending part 10
Lower arrival dead point F19 is led, at this point, the bending part 10 at the F19 of dead point will be upper if continuing upper poppet-valve core driver 24
It mentions, to realize above mentioning for spool.After above mentioning, switching spool device 24 is transferred, the end of the bending part 10 is slided in guiding
It is skidded off under the guidance of road B from upper inlet 16, so that the entirety of switching spool device 24 be enable to cross bending part in a downward direction
10 reach 10 lower section of bending part.Spool driver 24 cross after spool driver 24 can there are two types of subsequent action, one is after
Continuous downlink, goes to open or close next stage injection well downhole flow regulator, and action process is same as described above, another kind is upper proposition well, is above mentioned
Out when well, switching spool device 24 by the bending part 10 end when, the end of bending part 10 from the upper inlet 16 into
Enter guide slide B, and directly skidded off from the lower inlet 17 under the guidance of guide slide B, to make switching spool device 24
Entirety be able to cross bending part 10 in the upward direction and reach 10 tops of bending.
The guide sleeve 22 is two parts along axial cutting, and two parts form a complete tubular structure after fastening, often
A guide slide A is provided on the inside of partial, i.e. guide slide A shares two.
Guide slide A and guide slide B are process by way of milling.
The guide slide B at least three, quantity of the quantity of upper inlet 16 and lower inlet 17 with guide slide B
It is identical, it is connected between two adjacent upper inlets 16 (lower inlet 17) by wedge angle, it is ensured that the end of bending part 10 can be from any
Orientation swimmingly enters upper inlet 16 or lower inlet 17.
