Description

Manual casket plate blowout hookup
Technical field
The utility model relates to petroleum machinery field, is specifically related to manual casket plate blowout hookup.
Background technology
In oil drilling, well workover process, well kick and gas blowout accident happen occasionally, and must seal well head with preventer, to guarantee the safety of operating personnel and equipment.Development along with petroleum drilling technology, deep-well, ultradeep well get more and more, the oil well ratio of combined string significantly rises, and top adopts larger-diameter oil pipe, and bottom adopts the oil pipe of minor diameter, as adopt single ram type perventer, when lower tubular column, need the on-the-spot sealing of changing the applicable different tube diameters of flashboard to need, and the on-the-spot flashboard difficulty of changing, once there is blowout, and could not change in time flashboard, easily cause potential safety hazard.When workover treatment, in well, without oil pipe, down-hole pressure changes, and while occurring blowout trend, we just should take the precautionary measures in advance, avoid the generation of larger secret.Existing blowout hookup is in use due to corresponding support component and push-and-pull parts not being set, and packing unit seals more difficult and is in use easily damaged, and does not reach best blowout prevention effect, to production, makes troubles.
Utility model content
The utility model has overcome the deficiencies in the prior art, and manual casket plate blowout hookup is provided, provide special fixed block for the protection of flashboard seal assembly and ring gasket groove be also set blind rams is operated, and safety simple to operation, and be difficult for being damaged.
For solving above-mentioned technical problem, the utility model is by the following technical solutions: manual casket plate blowout hookup, comprise body, upper flange, lower flange, side door, fixed block, blind rams, bearing, leading screw and gate rubber core, the upper surface of described body and soffit are installed flange and lower flange successively, on the side of body, side door is installed, bearing passes across body; Described leading screw is arranged on bearing, can drive and be positioned at the flashboard seal assembly of bearing periphery to the central motion of body; Described blind rams and gate rubber core are positioned at the center of body, gate rubber core is positioned at blind rams, gate rubber core is connected with bearing, is also provided with ring gasket groove below blind rams, between upper flange and flashboard seal assembly, is also provided with fixed block.When turn leading screw is realized radial motion by leading screw by the screw thread in flashboard axis, drive both sides flashboard seal assembly to central motion, flashboard packing unit is now held oil pipe tightly simultaneously, reaches the object of closing blind rams and press seal glue core, realize sealing, reach the object of blowout prevention.Leading screw will produce pressure to the flashboard seal assembly of bearing periphery in pushing course, pressure is excessive also can damage flashboard seal assembly, be also provided with fixed block between upper flange and flashboard seal assembly, be exactly in order to increase the anti-pressure ability of flashboard seal assembly, avoid it to be damaged.
Described leading screw carries out radial motion by the flashboard axis internal thread arranging on bearing.
The top of described body is symmetrically arranged with two handles.
Described gate rubber core is square block.
The thickness of described fixed block is 2/3rds of body thickness.
Described ring gasket groove is L-type structure.Be convenient to leading screw and be rotated operation.
Compared with prior art, the beneficial effects of the utility model are:
1, the setting of the utility model fixed block between upper flange and flashboard seal assembly, the anti-pressure ability of increase seal assembly, avoids leading screw in motion process, to damage flashboard seal assembly, increases the application life of this device.
2, the design of ring gasket groove is not only played in bottom bearing is supported, and is convenient to blind rams to operate, and operates more simple and convenient.
3, the design of handle is convenient to the fixing of this device and is lifted operation.
Accompanying drawing explanation
Fig. 1 is sectional view of the present utility model.
In figure, Reference numeral is expressed as: 1, body; 2, upper flange; 3, lower flange; 4, side door; 5, fixed block; 6, blind rams; 7, bearing; 8, leading screw; 9, ring gasket groove; 10, gate rubber core; 11, flashboard seal assembly; 12, handle.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is further elaborated, embodiment of the present utility model is not limited to this.
Embodiment:
As shown in Figure 1, the utility model comprises body 1, upper flange 2, lower flange 3, side door 4, fixed block 5, blind rams 6, bearing 7, leading screw 8 and gate rubber core 10, leading screw 8 carries out radial motion by the flashboard axis internal thread arranging on bearing, and the top of body 1 is symmetrically arranged with two handles 12.
The upper surface of the body 1 of the present embodiment and soffit are installed flange 2 and lower flange 3 successively, and side door 4 is installed on the side of body 1, and bearing 7 passes across body 1; Leading screw 8 is arranged on bearing 7, can drive and be positioned at the flashboard seal assembly 11 of bearing 7 peripheries to the central motion of body 1.The blind rams 6 of the present embodiment and gate rubber core 10 are positioned at the center of body 1, gate rubber core 10 is positioned at blind rams 6, gate rubber core 10 is connected with bearing 7, below blind rams 6, be also provided with ring gasket groove 9, between upper flange 2 and flashboard seal assembly 11, be also provided with fixed block 5, gate rubber core 10 is square block, and the thickness of fixed block 5 is 2/3rds of body 1 thickness, and ring gasket groove 9 is L-type structure.
In workover treatment, down-hole pressure changes, while there is blowout sign, turn leading screw is realized radial motion by leading screw by the screw thread in flashboard axis, drive both sides flashboard seal assembly to central motion, flashboard packing unit is now held oil pipe tightly simultaneously, reaches the object of closing blind rams and press seal glue core, realize sealing, reach the object of blowout prevention.Fixed block wherein and ring gasket groove support and protect the upper and lower surface of flashboard seal assembly respectively, increase its measuring body ability, avoid it to be damaged, and increase the application life of this device.In addition, the design of ring gasket groove is also more conducive to the rotation of leading screw, operates more simple and convenient.The transfer of device is convenient in the design of handle, and the through hole on handle is convenient to the fixing of later stage, avoids this device to be moved.
Just can realize this utility model as mentioned above.
