Fig. 2 is fixed plate structure schematic diagram of the present invention.
In figure：1 flange, 2 through-holes, 3 self-sealing rubber cores, 4 inner ring, 5 bolts, 6 cavitys, 7 annular inflatable bags, 8 air bags, 9 screw threads
Hole, 10 threaded rods, 11 fixed plates, 12 balls, 121 card slots, 13 handles.
Specific implementation mode
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation describes, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall within the protection scope of the present invention.
- 2 are please referred to Fig.1, the present invention provides a kind of technical solution：A kind of hydraulic oil pipe self-packer, including flange 1, method
Through-hole 2 is offered on orchid 1, self-sealing rubber core 3 is equipped in through-hole 2, self-sealing rubber core 3 and the junction of flange 1 are equipped with inner ring 4, interior
Ring 4 is connect by bolt 5 with flange 1, forms cavity 6 between self-sealing rubber core 3 and flange 1, annular inflatable bag 7 is installed in cavity 6,
Flange 1 passes on left fixed frame installation air bag 8, and is connected to by conduit between air bag 8 and annular inflatable bag 7, the top of flange 1
Threaded hole 9 is offered at left and right sides of portion and bottom, is equipped with threaded rod 10 in threaded hole 9, threaded rod 10 is close to the side of through-hole 2
By bearing mounting plate 11, side of the fixed plate 11 far from threaded rod 10 is uniformly provided with ball 12, and threaded rod 10 is far from solid
The side of fixed board 11 is installed by handle 13.
Wherein, fixed plate 11 is arc panel, and fixed plate 11 is respectively mounted limit at the top and bottom of the side of threaded rod 10
Position bar, and the limit hole to match with gag lever post is offered on flange 1, be conducive to, by rotating handle 13, threaded rod 10 be made to move
Dynamic, gag lever post effectively prevents fixed plate 11 from and then rotating；
The card slot 121 to match with ball 12 is offered in fixed plate 11, and the opening diameter of card slot 121 is less than the straight of ball 12
Diameter is conducive to the rotation in card slot 121 of ball 12, while preventing ball 12 from falling, and oil pipe is facilitated to be inserted into and pull out in through-hole 2
Go out；
The volume of annular inflatable bag 7 is less than the volume of cavity 6, is conducive to be filled with air into annular inflatable bag 7 by air bag 8,
So that the expansion of annular inflatable bag 7 is squeezed self-sealing rubber core 3, so that self-sealing rubber core 3 is shunk, so that it is bonded between oil pipe closer, rises
It is acted on to better seal；
Self-sealing rubber core 3 is in infundibulate, and the inner wall of self-sealing rubber core 3 is uniformly provided with groove, is conducive to self-sealing rubber core 3 and passes through itself
Elasticity expand outwardly and complete tubing coupling, and embrace oil pipe using the inner wall rubber part of self-sealing rubber core 3, play sealing, it is recessed
Slot can strike off the sundries on oil pipe when into and out oil pipe, prevent pollution environment；
Handle 13 is equipped with S type anti-skid chequers, and S type anti-skid chequer rectangular arrays are arranged, and increases rubbing between palm and handle 13
Power is wiped, rubber sleeve is prevented.
Operation principle：Flange 1 is mounted on wellhead blowout preventor, oil pipe is inserted into through-hole 2, oil pipe is made to pass through from sealing
Core 3, by self-sealing rubber core 3, the elasticity of itself expands outwardly the inner wall rubber part completed tubing coupling, and utilize self-sealing rubber core 3
Oil pipe is embraced, while by rotating handle 13, so that threaded rod 10 is moved, so that fixed plate 11 is clamped oil pipe, prevent oil pipe
Inclination causes eccentric wear to self-sealing rubber core 3, so that it is lost leakproofness, while being filled with air into annular inflatable bag 7 by air bag 8,
So that the expansion of annular inflatable bag 7 is squeezed self-sealing rubber core 3, so that self-sealing rubber core 3 is shunk, so that it is bonded between oil pipe closer, rises
It is acted on to better seal.
