Description of drawings
Fig. 1 is the structural representation of the utility model;
Fig. 2 is the water nozzle regulating sleeve structural representation of the utility model;
Fig. 3, Fig. 4 are that the A of Fig. 2 is to view;
The specific embodiment
Referring to Fig. 1; The concentric injection well downhole flow regulator of down-hole scalable of the utility model, comprise top connection 1, cylindrical shell 2, urceolus 3, water nozzle regulating sleeve 4, split washer 5, movable water nozzle 6, arc key 7, packing ring 8, fixedly water nozzle 9. baffle ring 10, water nozzle fixed cover 11, flat key 12, lower contact 13, first sealing ring 14, second sealing ring 15 and the 3rd sealing ring 16; Fixedly water nozzle 9, water nozzle regulating sleeve 4 and water nozzle fixed cover 11 all are arranged in the cylindrical shell 1, movable water nozzle 6 and fixedly water nozzle 9 flexible connections; Movable water nozzle 6 is arranged on fixedly in the water nozzle 9, closely cooperates and fixedly water nozzle 9 inwall lengthwise movements of edge with fixing water nozzle 9 no gaps; Be threaded between water nozzle regulating sleeve 4 and the cylindrical shell 1, adopt trapezoidal thread in the utility model; Water nozzle regulating sleeve 4 connection activity water nozzles 6, fixedly water nozzle 9 connects and the fixing water nozzle fixed cover 11 in cylindrical shell bottom, and fixedly water nozzle 9 is adaptive with cylindrical shell 1; Two weep holes are fixedly arranged on the water nozzle 9, and diameter is 12 millimeters, radially is symmetricly set in respectively on the wall of fixing water nozzle 9.Movable water nozzle 6 all adopts high strength high-quality pottery (zirconia) to grind through sintering with fixing water nozzle 9 and forms; Be connected through arc key 7 between movable water nozzle 6 and the water nozzle regulating sleeve 4; Fixedly be connected through flat key 12 between water nozzle 9 and the water nozzle fixed cover 11; First sealing ring 14 is set between water nozzle regulating sleeve 4 and the cylindrical shell 2; Second sealing ring 15 fixedly is set between water nozzle 9 and the cylindrical shell 2, the 3rd sealing ring 16 is set between water nozzle fixed cover 11 and the cylindrical shell 2.
The concentric injection well downhole flow regulator of down-hole scalable of the utility model, in actual use and the water filling adjusting device use together, can realize the monitoring; After the water filling adjusting device is pressed under the routine operation technology layer position with this injection well downhole flow regulator; Transfer concentric intelligent measurement and adjustment instrument with cable and to sit on layer position; The driving cone of instrument just can drive water nozzle regulating sleeve 2 and move up and down through acme thread, thereby drive activity water nozzle 6 is fixedly moving up and down in the middle of the water nozzle 9 simultaneously, reaches the fixing delivery port of water nozzle 9 is opened greatly or the effect that turns down; So water injection rate also changes thereupon; Because the fixedly water nozzle in this injection well downhole flow regulator and the fit clearance of movable water nozzle are very little, test the envelope effect so also can reach, and test envelope work operation and time thereby saved greatly.
Referring to Fig. 2; Water nozzle regulating sleeve 4 itself has 4 rectangle breach, is used for being connected usefulness with the water filling adjusting device, can regulate its rotation of rotation drive of head through the water filling adjusting device; And two arc keys 7 of movable water nozzle 6 usefulness link to each other with water nozzle regulating sleeve 4; Having of water nozzle regulating sleeve 4 itself from slippage mechanism, from slippage mechanism be arranged on water nozzle regulating sleeve 4 inwalls and with regulate an adaptive inclined plane groove 17, inclined plane groove 17 is four; Evenly distribute an inclined plane groove 17 and an adjusting tangent setting along water nozzle regulating sleeve 4 inwalls; When water nozzle regulating sleeve 4 is adjusted to water nozzle and closes dead extreme lower position; The lower end of water nozzle regulating sleeve 4 contacts with water nozzle fixed cover 11, can't continue motion downwards, but whole instrument is rotated further also; At this moment instrument regulate two flexible pieces 16 on the head will be because of the pressure that receives the inclined-plane automatic drawing back; Referring to Fig. 3, so both protected the adjusting apparatus motor, water nozzle regulating sleeve 4 and water nozzle fixed cover 11 are not killed each other.Yet, if instrument regulate in the opposite direction because the effect of flexible piece 16; The water nozzle regulating sleeve 4 can continue to move upward again, when water nozzle regulating sleeve 4 moves to topmost, equally also has from slippage mechanism; Referring to Fig. 4, principle is the same with above-mentioned principle, and direction is then opposite.
