Abstract
Provided is an efficient energy-saving wellhead self-sealing blowout preventer. The efficient energy-saving wellhead self-sealing blowout preventer mainly solves the problem that an existing blowout preventer needs to be adjusted frequently. The efficient energy-saving wellhead self-sealing blowout preventer is characterized in that an annular boss (3) is arranged outside the lower portion of a packing barrel (2) and is sleeved with a connecting cap (4), the packing barrel (2) moves by 360 degrees in the connecting cap (4), the connecting cap (4) is connected to the upper end of a connector (1), a sealing ring (5) is arranged on the contact face between the connecting cap (4) and the connector (1), taper packing (6) is arranged in a big-end-up taper hole of the packing barrel (2), a pressing plate (7) is arranged at the upper end of the packing and provided with a compression spring (8), and a pressing cap (9) on the compression spring (8) is connected with the packing barrel (2). The efficient energy-saving wellhead self-sealing blowout preventer has the advantage of self-adjusting.
Description
Technical field:
The utility model relates to a kind of oil field shaft mouth blowout preventer used, especially energy-efficient wellhead self-sealing blowout preventer.
Background technology:
Blowout preventer is all installed on oil-field oil pumper well head.And current existing blowout preventer is because reasons in structure exists the problem frequently regulating, make terrible the tightening of packing pine, the partially terrible tune of polished rod.Thereby greatly increase labor strength and downtime, and increase cost for oil production, affect the normal operation of oil well.
Utility model content:
In order to solve the frequent problem regulating of existing blowout preventer.The utility model provides a kind of energy-efficient wellhead self-sealing blowout preventer.This energy-efficient wellhead self-sealing blowout preventer has the feature of automatic adjusting.
The technical solution of the utility model is: this energy-efficient wellhead self-sealing blowout preventer comprises joint and packing cylinder.Packing cylinder has annular boss outside bottom, on annular boss, cover has attachment cap, packing cylinder 360 degree in attachment cap are mobile, attachment cap is connected to upper end of joint, attachment cap and joint contact surfaces have sealing ring, and the up big and down small bellmouth of packing cylinder is built-in with tapered packing, and there is pressing plate packing upper end, on pressing plate, have stage clip, stage clip upper pressing cap is connected with packing cylinder.
The utlity model has following beneficial effect: this energy-efficient wellhead self-sealing blowout preventer has annular boss owing to adopting outside packing cylinder bottom, on annular boss, cover has attachment cap, packing cylinder 360 degree in attachment cap are mobile, attachment cap is connected to upper end of joint, attachment cap and joint contact surfaces have sealing ring, and the up big and down small bellmouth of packing cylinder is built-in with tapered packing, and there is pressing plate packing upper end, on pressing plate, there is stage clip, the structure that stage clip upper pressing cap is connected with packing cylinder.Utilize stage clip automatically to regulate packing degree of tightness.Utilize packing cylinder mobile automatic deflection adjusting of 360 degree in attachment cap, thereby reduce labor strength and cost for oil production, reduce downtime, increase the recovery ratio of oil well.This energy-efficient wellhead self-sealing blowout preventer has the feature of automatic adjusting thus.
Brief description of the drawings:
Accompanying drawing 1 is the utility model structural representation.
1-joint in figure, 2-packing cylinder, 3-boss, 4-attachment cap, 5-sealing ring, 6-packing, 7-pressing plate, 8-stage clip, 9-pressure cap.
Detailed description of the invention:
Below in conjunction with accompanying drawing, the utility model is described in further detail:
As shown in the figure, this energy-efficient wellhead self-sealing blowout preventer comprises joint 1 and packing cylinder 2.Packing cylinder has annular boss 3 outside 2 bottoms, on annular boss 3, cover has attachment cap 4, annular boss 3 external diameters are less than attachment cap 4 internal diameters, the through hole internal diameter of crossing polished rod on joint 1 is greater than polished rod external diameter, packing cylinder 2 360 degree in attachment cap 4 are mobile, attachment cap 4 is connected to joint 1 upper end, and packing cylinder 2 can be moved by 360 degree in attachment cap 4, realizes automatic deflection adjusting function.Attachment cap 4 has sealing ring 5 with joint 1 contact surface, by sealing ring 5 be tightly connected cap 4 and joint 1 contact surface.The up big and down small bellmouth of packing cylinder 2 is built-in with tapered packing 6, and there is pressing plate 7 packing upper end, has stage clip 8 on pressing plate 7, and the pressure cap 9 on stage clip 8 is connected with packing cylinder 2, automatically regulates packing 6 compaction degrees by stage clip 8.
