Description
Technical field
This utility model relates to water injection well in oil fields ball-and-seat maintenance tool, specifically a kind of water injection well single current valve bonnet extractor.
Background technology
At present in water injection well in oil fields the injecting process, owing to being produced-water reinjection, water quality is poor, impure many, causes ball-and-seat fouling serious, ball valve is sat the tightest with valve seat, not having the effect of non-return, once water injecting pump termination of pumping, pressure reduction causes water injection well oil reservoir guttation, shakes out, the lighter affects the water injection rate of water injection well, causes water injection well to lie well time serious.Thus, the maintenance of water injection well ball-and-seat is regular work, and owing to water injection well ball-and-seat is vertical, valve bonnet is difficult to take out, and wastes time and energy, and maintenance time is long, affects the normal water filling of water injection well.
Summary of the invention
The purpose of this utility model is aiming at the drawbacks described above that prior art exists, and devises a kind of water injection well single current valve bonnet extractor.
The purpose of this utility model is achieved through the following technical solutions:
This utility model includes: center-pole, silk braid, support, crossbeam, hinge, pulling force pawl, righting board, fixing axle, righting axle.The carriage center of described water injection well single current valve bonnet extractor is provided with through hole, is provided with silk braid in through hole, and center-pole connects through with silk braid female thread, and center-pole is fixedly connected with the centre of crossbeam, in "
T
" type structure, the two ends of crossbeam are respectively connected to a pulling force pawl by hinge, in the bottom of support by the fixed righting board of fixing axle, are provided with righting axle in the middle of righting board
Support in above-mentioned water injection well single current valve bonnet extractor for fall "
U
" type structure, lower end is provided with opening.
The upper end of the pulling force pawl in above-mentioned water injection well single current valve bonnet extractor is provided with draw ring, and lower end is provided with right angle hook.
Being divided into before and after righting board in above-mentioned water injection well single current valve bonnet extractor is two pieces, and centre is provided with four righting axles, movable plug.
The beneficial effects of the utility model are: being applicable to the maintenance of water injection well in oil fields ball-and-seat, valve bonnet is convenient to remove, time saving and energy saving, shortens maintenance time, makes the normal water filling of water injection well, ensure that oilfield crude oil normally produces.
