Abstract
A kind of continuously adjustabe water nozzle, relates to the design field of water nozzle used in petroleum production engineering stratified injection water technology.The utility model comprises adjustable spool, shaft coupling, valve pocket, arranges contact control lever on shaft coupling top by bolt; Shaft coupling is in transmission connection above adjustable spool; In the middle part of adjustable spool, radial direction arranges the first through hole; Valve pocket is nested with outside adjustable spool, and on valve pocket, radial direction arranges the second through hole; Outside valve pocket, be nested with joint ring, on joint ring, radial direction arranges third through-hole; First through hole, the second through hole and third through-hole are arranged on the same axis.The utility model avoids pulling complicated processes, has saved man power and material, has improve operating efficiency, ensures that wastage is less than 0.3 side/sky.
Description
Technical field
The utility model relates to the design field of water nozzle used in petroleum production engineering stratified injection water technology.
Background technology
Water nozzle mainly controls the effect of dispensing flow at separate water injection well, and the well of early stage various dispensing mode all adopts instrument pulling to go out water distribution plug, manually changes the ceramic water nozzle of different pore size at well head, to reach injection allocation flow.The patent No. be 02229078.8 disclose a kind of Constant flow water tap also just solve well head pressure change control the current of constant flow, pulling mode is the same with raw mode loaded down with trivial details, and repeatedly pulling efficiency is low, and in pulling process easily block, easily come off.The patent No. is 200920245843 disclose a kind of adjustable water nozzle, and adjust water nozzle size by axially-movable, although solve the loaded down with trivial details problem of pulling, axially-movable will overcome the defect of down-hole pressure resistance, and wastage reaches 3 sides/day.
Utility model content
The utility model object is for above problem, provides a kind of easy to use, continuously adjustabe water nozzle of raising the efficiency.
The utility model comprises adjustable spool, shaft coupling, valve pocket, arranges contact control lever on described shaft coupling top by bolt; Described shaft coupling is in transmission connection above adjustable spool; In the middle part of described adjustable spool, radial direction arranges the first through hole; Described valve pocket is nested with outside adjustable spool, and on described valve pocket, radial direction arranges the second through hole; Outside described valve pocket, be nested with joint ring, on described joint ring, radial direction arranges third through-hole; Described first through hole, the second through hole and third through-hole are arranged on the same axis.
The beneficial effects of the utility model are: during work, adjustable spool can rotate by different angles under stepper motor transmission, water nozzle need not be changed in a traditional way and just can reach adjustment water nozzle opening degree, thus reach injection allocation requirement, avoid pulling complicated processes, save man power and material, improve operating efficiency, adjustable spool and valve pocket accomplish blind-mate in addition, and it is little that rotation overcomes resistance, be furnished with joint ring, ensure that wastage is less than 0.3 side/sky.
The ring wall of joint ring described in the utility model is provided with axial slot, joint ring has impulse groove, and pressure balance rear motor rotates and reaches labour-saving effect.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation of the utility model joint ring.
Detailed description of the invention
As shown in Figure 1, 2, the utility model comprises adjustable spool 1, shaft coupling 2, valve pocket 3, arranges contact control lever 5 on described shaft coupling 2 top by bolt 4; Described shaft coupling 2 is in transmission connection above adjustable spool 1; In the middle part of described adjustable spool 1, radial direction arranges the first through hole 6; Described valve pocket 3 is nested with outside adjustable spool 1, and on described valve pocket 3, radial direction arranges the second through hole 7; Outside described valve pocket 3, be nested with joint ring 8, on joint ring 8, radial direction arranges third through-hole 9; First through hole 6, second through hole 7 and third through-hole 9 are arranged on the same axis; The ring wall of joint ring 8 is provided with axial slot 10.
