Abstract
The utility model relates to a clamp sealing steel ring hydraulic pressure ware that expands is changed to water injection well head. Mainly solved when current processing water injection well head clamp seepage one clamp reveal need unload 2 or 3 clamps waste time and energy low efficiency problem. The method is characterized in that: righting two fixed tip wedges of steel sheet (2) lower part, two righting steel sheet wedges lower parts are opened and are had two eyelets, two eyelet dress fixing bolt (4), righting steel sheet (2) upper portion and leaning on round pin axle (5) to be connected with U type crossbeam (6), top circle (7) are connected to crossbeam (6) upper portion horizontal cross rod bottom, the overhead hoop head (8) that has put of wedge , the overhead crescent base (9) of hoop are located, have hydraulic jack (1) between top circle (7) and crescent base (9). This water injection well head is changed clamp sealing steel ring hydraulic pressure ware of expanding realizes a clamp seepage, only needs to unload this seepage clamp and just can handle water injection well head clamp seepage problem, high-efficient labour saving and time saving.
Description
Technical field
The utility model relates to a kind of hydraulic pressure expander in oil extraction in oil field technical field, and particularly a kind of water injection well changes clip ring gasket hydraulic pressure expander.
Background technology
Water injection well, because seasonal variations, water injection pressure are not steady, easily causes clip seepage.If a clip seepage, during process, need to unload 2 or 3 clips.And while processing seepage, too increase seepage probability, waste time and energy, reduce production efficiency.
Summary of the invention
Technical problem to be solved in the utility model is that when overcoming the existing process water injection well clip seepage existed in background technology, clip is revealed and needed to unload 2 or 3 clips and to waste time and energy the problem of poor efficiency, and provide a kind of water injection well to change clip ring gasket hydraulic pressure expander, this water injection well changes clip ring gasket hydraulic pressure expander, realize a clip seepage, only need unload this seepage clip just can process water injection well clip leakage problems, and high efficiency and time conservation is laborsaving.
The invention for solving the technical problem reaches by following technical scheme: this water injection well changes clip ring gasket hydraulic pressure expander, comprise hydraulic jack and righting steel plate, two swollen wedges of tip are fixed in described righting steel plate bottom, the two swollen wedge bottoms of righting steel plate have two eyelets, two eyelet dress set bolts, described righting steel plate top is connected with U-shaped crossbeam by bearing pin, collar is connected bottom described crossbeam upper level cross bar, described swollen wedge is equipped with hoop, hoop top is sat crescent base, is equipped with hydraulic jack between collar and crescent base.
The utility model can have following beneficial effect compared with above-mentioned background technology: this water injection well changes clip ring gasket hydraulic pressure expander owing to adopting said structure, hydraulic pressure expander is applied to water injection well process wellhead collar clamp seepage, save time than before over half, reach a clip seepage, unload seepage clip and directly change ring gasket, need not unload other clip, process seepage reduces seepage probability simultaneously, saves time, laborsaving, efficient.
accompanying drawing illustrates:
Accompanying drawing 1 is structural representation of the present utility model.
In figure: 1-hydraulic jack, 2-righting steel plate, 3-is swollen wedge, 4-set bolt, 5-bearing pin, 6-crossbeam, 7-collar, 8-hoop, 9-base.
Below in conjunction with accompanying drawing, the utility model is described in further detail:
As shown in Figure 1, this water injection well is changed clip ring gasket hydraulic pressure expander and is comprised hydraulic jack 1, righting steel plate 2, described righting steel plate 2 bottom is screwed two swollen wedges 3 of tip, two righting steel plates swollen wedge 3 bottom has two eyelets, two eyelet dress set bolts 4, described righting steel plate 2 top is connected with U-shaped crossbeam 6 by bearing pin 5, collar 7 is connected bottom described crossbeam 6 upper level cross bar, described swollen wedge 3 is equipped with hoop 8, hoop 8 top is sat crescent base 9, hydraulic jack 1 is equipped with between collar 7 and crescent base 9, described crescent moon base 9 radian is identical with circular hoop radian.
This water injection well changes clip ring gasket hydraulic pressure expander, jack base is sitting on crescent base, crescent base diagonal angle drill two holes eye, at holes intraocular tapping, be connected and fixed jack base with two screws, crescent moon base radian is identical with circular hoop radian, and two swollen wedges of tip are screwed at righting steel plate lower position, when realizing loading and unloading hydraulic expander, dress pin righting steel plate can be that the free opening and closing of axle are opened with bearing pin.
During process water injection well clip seepage, sky flow process of putting upside down, unloads seepage clip, loads onto hydraulic pressure expander, and swell hoop gap, takes out old steel ring, changes new steel ring, unloads hydraulic pressure expander, loads onto new steel ring, loads onto clip and tighten, the flow process of falling water filling.Realize a clip seepage, only need unload this seepage clip just can process water injection well clip leakage problems, saves the time over half, reaches safe and efficient, time saving and energy saving.
Claims (2)
1. a water injection well changes clip ring gasket hydraulic pressure expander, comprise hydraulic jack (1) and righting steel plate (2), it is characterized in that: two swollen wedges of tip (3) are fixed in described righting steel plate (2) bottom, two righting steel plates swollen wedge (3) bottom has two eyelets, two eyelets dress set bolt (4), described righting steel plate (2) top is connected with U-shaped crossbeam (6) by bearing pin (5), collar (7) is connected bottom described crossbeam (6) upper level cross bar, described swollen wedge (3) is equipped with hoop (8), hoop (8) top is sat crescent base (9), hydraulic jack (1) is equipped with between collar (7) and crescent base (9).
2. water injection well according to claim 1 changes clip ring gasket hydraulic pressure expander, it is characterized in that: described crescent base (9) radian is identical with circular hoop (8) radian.
