Abstract
The utility model relates to an adjustable well blowout preventer, which has a skew adjusting structure, a hoop type excursion adjusting structure, and a concentric closing well structure in order to completely adjust the sucker rod which has a skew and excursive shaft line, extend the service life of the sealing ring, prevent the blowout, and prevent the leakage. The concentric closing well structure is arranged between the skew adjusting structure and the hoop type excursion adjusting structure, and a case body of the concentric closing well structure has a rigid connection with a sphere supporting seat of the skew adjusting structure and an excursion adjusting seat of the hoop type excursion adjusting structure.
Description
The utility model belongs to and has from the deep-well aboveground protector of lifting fluid and free plunger displacement pump earthward, particularly adjustable well blowout preventer.
From deep-well earthward the sucker rod on the plunger displacement pump of lifting fluid axis often relatively the well head axis skew and crooked takes place, thereby the sealing wear that makes aboveground device seriously, sealing effectiveness is poor, causes the well head place seriously to leak.For this reason, usually adopt by adjusting crooked structure and the closing well structure is formed or move the aboveground device that structure and closing well structure are formed by the flange form tuningout, these two kinds of devices are not only because the axis adjustment is incomplete, can not solve thoroughly that sealing wear is serious, sealing effectiveness difference and the serious leakage that causes, and owing to close well construction and be in tuningout and move between structure and the wellhead assembly, make the center line of pass well construction and the axis decentraction of sucker rod, thereby when closing well, be not closed completely, blowout takes place.
The purpose of this utility model provide a kind of have transfer crooked structure, clamping hoop type tuningout move structure and with one heart the axis adjustment formed of closing well structure fully, prolong joint ring application life, the adjustable well blowout preventer of blowout prevention leakproof.
The utlity model has and transfer crooked structure, clamping hoop type tuningout to move structure and close well construction with one heart, close well construction with one heart and transferring crooked structure and clamping hoop type tuningout to move between the structure, the spheroid bearing of its housing and the crooked structure of accent and the tuningout that tuningout moves structure move seat and are rigidly connected.
Transfer crooked structure, clamping hoop type tuningout to move structure and close well construction with one heart owing to the utlity model has, and make concentric pass well construction transfer crooked structure and clamping hoop type tuningout to move between the structure, the spheroid bearing of its housing and the crooked structure of accent and the tuningout that tuningout moves structure move seat and are rigidly connected, thereby the axis of sucker rod is overlapped fully with the well head axis, prolong the application life of joint ring, prevent to leak, and guarantee that concentric closing well structure centre is concentric with sucker rod, when changing joint ring, can reach tight closing and prevent blowout, thereby reach the purpose of this utility model.
Fig. 1 is the utility model structural representation.
Below in conjunction with accompanying drawing the utility model is further elaborated.
The utility model closes well construction 3 with one heart and is transferring crooked structure 1 and clamping hoop type tuningout to move between the structure 2 by transferring crooked structure 1, clamping hoop type tuningout to move structure 2 and close well construction 3 with one heart and form; Transfer crooked structure 1 to have the seal ring seat 5 that several joint rings 4 is housed the center, the one end is threaded with gland 6, between gland 6 and joint ring 4 of topmost, has clamp sleeve 7, the other end of seal ring seat 5 is a ballhead 8, the lower, outer perimeter of ballhead 8 withstands on periphery and has external screw thread 9, be equipped with in interior week to have and match on the spheroid bearing 11 of joint ring 10 of Internal Spherical Surface with ballhead 8, ballhead 8 upper periphery are with an end and have the Internal Spherical Surface that matches with ballhead 8, the other end has the clamp nut 12 that is connected with the external screw thread 9 of spheroid bearing 11, and locking nut 13 also is housed on external screw thread 9; The clamping hoop type tuningout moves the tuningout that structure 2 has flanged pin 14 and moves seat 15, the upper and lower pressure ring 16,17 that band compresses wedge surface is equipped with in the above and below of moving seat 15 flange 14 at tuningout, and flange 14 peripheries of moving seat 15 at upper and lower pressure ring 16,17 and tuningout are with to have and compress interior wedge surface that wedge surface matches with upper and lower pressure ring 16,17 and with the fastening clip 19 of bolt 18; Close with one heart well construction 3 and have the rigidly connected housing 20 of the other end that moves seat 15 with spheroid bearing 11 other ends of transferring crooked structure 1 and tuningout that tuningout moves structure 2, left and right gland 21,22 is equipped with at the two ends of housing 20, one end is equipped with left and right handwheel 23,24, and the left and right screw rod 27,28 that the other end is connected with left and right guiding valve 25,26 is through in the screw 29,30 of left and right gland 21,22; The other end at left and right guiding valve 25,26 is equipped with left and right bowl-shape semitight ring 31,32.
When the axis of sucker rod 33 and well head axis take place when crooked, unclamp locking nut 13 and clamp nut 12, make seal ring seat 5 nationalitys help ballhead 8 between the Internal Spherical Surface of the joint ring 10 of spheroid bearing 11 and clamp nut 12 along freely rotating in 360 ° of scopes around the sucker rod 33, make sucker rod 33 upper and lower motions also tighten clamp nut 12 gradually and tighten locking nut 13, then finish the crooked adjustment of axis.
When skew takes place in the axis of sucker rod 33 and well head axis, unclamp bolt 18, interior wedge surface on the clip 19 and the dog wedge emaciated face on the upper and lower pressure ring 16,17 are opened, tuningout move seat 15 drive close well construction 3 with one heart and transfer crooked structure 1 together can be around the sucker rod 33 translation in 360 ° of scopes, until its axis and sucker rod 33 deads in line, the fastening nut bolt 18 gradually, make the wedge surface that compresses on interior wedge surface on the clip 19 and the upper and lower pressure ring 16,17 coincide and compress the flange 14 that tuningout moves seat 15, finish the journal offset adjustment.
In the time will changing joint ring 4, rotate left and right handwheel 23,24, left and right screw rod 27,28 is rotated in the screw 29,30 of left and right gland 21,22 and drive left and right guiding valve 25,26 and move to the center, the left and right bowl-shape semitight ring 31,32 of left and right guiding valve 25,26 ends is clamped on the sucker rod 33, reach sealing fully, prevent oil spout when taking out joint ring 4.
