Abstract
The utility model relates to a cable sealing device of electric pump suspender at the mouth of oil well. A cable channel is provided on the main body of the suspender, a gasket is provided on the outermost end of the cable channel, and a pressure plate arranged at the outside of the gasket is fixed through screws. The cable channel has a rectangular tapered bevel, and the gasket is a tapered body matching the rectangular bevel. Preferably, one or more separated-type tapered bodies with cable holes are provided at the middle of the gasket. Under pressure of the screws, the gasket is tightly pressed by the pressure plate such that it produces outward expansion and inward shrinkage to completely seal the cable channel, thereby improving working efficiency greatly.
Description
One, technical field:
The utility model relates to a kind of important sealing device, the electric pump hanger cable sealing device on particularly a kind of electric pump producing well well head.
Two, background technology:
The electric pump hanger is to use the important sealing device on the electric pump producing well well head, and the cable of oil extraction pump is guided on the power distribution equipment of ground passing hanger between oil pipe and the sleeve pipe.Recover the oil or in the well very big pressure (about 5MPa-10MPa) is arranged during well-flushing, any place of regulation well head this moment does not allow Lou oozes phenomenon, so hanger cable aperture road exports how to seal and just seems particularly important.
At present, the former sealing device of hanger is with the dull and stereotyped extruding of two perforated metal perforated flat plate oil-resistant rubber slab, distortion tension by rubber slab seals, as accompanying drawing 6: i.e. processing cable duct 12 on hanger body 11, have two rectangle stepped holes in cable duct outermost end, on first stepped hole, lay a perforated metal flat board 13, lay oil-resistant rubber insert 14 then, lay second perforated metal flat board 15 again, put a thicker long pressing plate 16 above again, use the above all plates of hold-down bolt 17 spinning at last, employing screws the pressure of bolt, the crowded power extruding rubber blanket 14 that metal plate 13 and backing plate 15 are produced make its distortion outwards (main body oblong aperture) stretch to rise with inwardly (three cables) and seal.But the problem that occurs in the reality is: when borehole pressure was increased to 5MPa, the liquid between oil pipe and sleeve pipe was just along gap between cable duct pressing plate and the main body and the gap upper punch between the rubber blanket and the outside diameter of cable, made the distortion of oil resistant rubber sealing gasket and leaked.Simultaneously, because of well head and ground power distribution equipment distance is far away, all backing plate three holes all will begin to penetrate from the cable leader, and sealing effectiveness is bad during the little use in line length hole, inefficiency.
Three, summary of the invention:
The purpose of this utility model is exactly the above-mentioned defective that exists at prior art, provides place, a kind of hanger cable duct not leak and does not ooze, and is easy for installation, keeps in repair electric pump hanger cable sealing device efficiently.
Its technical scheme is: be provided with the cable duct on hanger body, the outermost end in the cable duct is equipped with sealing gasket, and sealing gasket is provided with pressing plate outward, and by screwing the bolt pressing plate, wherein: described cable duct is rectangle awl inclined-plane; The awl italic of described sealing gasket for matching with rectangle awl inclined-plane.
Preferable technical scheme is that described sealing gasket is the middle split type awl italic that is provided with more than one cable aperture.
Better technical scheme is that described sealing gasket is the two-piece type awl italic that is provided with three cable aperture; The both sides of the outermost end in described cable duct have been provided with the sled hole; And be provided with the sled groove on described pressing plate both sides.
The beneficial effects of the utility model are: because the pressure that bolt tightens, make pressing plate compress sealing gasket, force sealing gasket to move down along the awl inclined-plane of hanger body, sealing gasket causes outside expanding and inwardly shrinks under strong pressure, outwards the expanding jam-packed awl inclined-plane in cable duct; The outer diametric plane of three cables that inwardly shunk jam-packed, thus reached the sealing fully of cable passage, improved operating efficiency greatly.

Accompanying drawing 2 is vertical views of the present utility model;
Accompanying drawing 3 is cutaway views of pressing plate of the present utility model;
Accompanying drawing 4 is longitudinal sectional views of sealing gasket of the present utility model;
Accompanying drawing 5 is transverse sectional view of sealing gasket of the present utility model;
Accompanying drawing 6 is longitudinal sectional views of the former sealing device of hanger.
Five, embodiment:
In conjunction with the accompanying drawings 1,2,3,4,5 and 6, the utility model will be further described:
Its technical scheme is: be provided with cable duct 22 on main body 21, that outermost end in cable duct 22 is equipped with is high temperature resistant, the rubber gasket 23 of high pressure, the sealing gasket 23 outer pressing plates 24 that are provided with, be provided with cable perforation 28 in the middle of the pressing plate 24, by screwing bolt 26 fixation clips 24, wherein: described cable duct 22 is rectangle awl inclined-plane; The two-piece type awl italic that be provided with three cable aperture 25 of described sealing gasket 23 for matching with rectangle awl inclined-plane; The both sides of the outermost end in described cable duct 22 have been provided with sled hole 27; And be provided with sled groove 29 on described pressing plate both sides.
Use is: electric pump producing well is not before hanger is installed, devices such as oil recovery electric pump, cable, well head install all that (electric pump is in the shaft bottom, cable is in well between oil pipe and the sleeve pipe, well head is on ground, cable tail is to the ground power distribution equipment), hanger sealing well head just is installed at last.Rotatably compress by screwing bolt 26, promptly, make pressing plate 24 compress rubber gasket 23, force rubber gasket 23 to move down along the rectangle awl inclined-plane of hanger body 21 owing to screw the pressure that bolt 26 tightens.Rubber gasket 23 causes outside expanding and inwardly shrinks under strong pressure, outwards the expanding jam-packed awl inclined-plane in cable duct; The outer diametric plane of three cables that inwardly shunk jam-packed, thus reached the sealing fully in cable duct.
During maintenance, screw off screw bolt 26 after, utilize lever principle to prize slightly from pressing plate 24 two ends sled groove 29 insertion circular knifes and can take off pressing plate, go up the portable cable lead-in wire then a little, rubber gasket can take out with carrying on the cable, has reached easy for installation, keeps in repair requirement efficiently, use this product to alleviate labour intensity, improved operating efficiency.
Experiment and use (inferior surplus in the of 60) through Shengli Oil Field units concerned prove: this sealing device is the primary seal material owing to selected the rubber of HTHP for use, and has utilized the self-styled principle of cone face under pressure.When oil recovery or well-flushing, because borehole pressure rises, the pressure that the liquid of upper punch causes returns and squeezes rubber gasket 23, but there is pressing plate sealing rubber pad top and screws the fastening of bolt and can't rise, and just forces the outside expanding of rubber gasket to push gap with the awl inclined-plane in hanger body cable duct more; Inwardly shrink jam-packed more with the gap of those three cable outer surfaces, thereby more increased the sealing of cable conduit.Reached user's instructions for use.Because we have adopted rubber is the primary seal material, guaranteed that more cable can not be overstock damage.
