Abstract
The utility model discloses a Level II deflection adjustment packing box, which comprises a packing box body and a flange panel. The bottom of the packing box body extends outwards in horizontal direction to form an eccentric disk. The lower part of the packing box body is covered by a pressing sleeve, the bottom of which presses on the surface of the eccentric disk and the outer circumferential wall of the lower part of the pressing sleeve is provided with outer threads. The pressing sleeve is connected with an eccentric base which appears concave shape on a vertical section and covers a sucker polished rod. The hole diameter of the polished rod hole of the eccentric base underside is less than the outer diameter of the eccentric disk which contacts with the underside of the eccentric base. The outer circumferential wall of one side of the eccentric disk contacts with the inner circumferential wall of one side of the eccentric base. The outer circumferential wall of the lower part of the eccentric base is provided with an outwards protruding ring shoulder. The flange panel is covered and arranged on the top of the ring shoulder of the eccentric base. The utility model realizes accurate adjustment by Level II deflection adjustment, which ensures the packing box is in the central position when in operation, effectively reduces the packing box abrasion, prolongs effective cycle of the packing box, reduces the deflection adjustment strength.
Description
Technical field
The utility model belongs to the improvement, particularly secondary tuningout packing box of oil field pumping well with the packing box structure.
Background technology
At present, generally all on the oil pumping polish rod at well head place, packing box be installed in the oil field pumping well manufacturing process, in order to oil pumping polish rod is played sealing function.In the actual production process, oil pumper is moved sometimes, causes the position of oil pumping polish rod in packing box to be offset, and the wearing and tearing that increased packing cause the packing box sealing performance to descend.The someone has developed the tuningout packing box for this reason, in order to adapt to the change in location of oil pumping polish rod, alleviates the packing wearing and tearing.But, in process of production, it is found that traditional tuningout packing box tuningout precision is limited, need the dismounting flange to carry out tuningout, labour intensity is big during workman's tuningout.
The utility model content
The purpose of this utility model is to provide a kind of secondary tuningout packing box, and it is simple in structure, and labor strength is low during not only accurate tuningout, and tuningout.
The purpose of this utility model is achieved in that a kind of secondary tuningout packing box, comprise and being sleeved on the oil pumping polish rod, the packing box body and the flange of packing are housed in its top, the bottom level of packing box body is outwards expanded and is constituted an eccentric disc, suit gland outside the packing box body bottom, the bottom of gland is pressed on the eccentric disc card, on the lower, outer perimeter wall of gland external screw thread is being set, gland is concave shape by external screw thread and a vertical section, the eccentric mount that is sleeved on the oil pumping polish rod links to each other, the aperture in the polished rod hole of eccentric mount bottom is less than the external diameter of eccentric disc, eccentric disc contacts with the eccentric mount bottom surface, one side periphery wall of eccentric disc contacts with a side internal perisporium of eccentric mount, the annular shoulder block of evagination is being set on the lower, outer perimeter wall of eccentric mount, and flange is sleeved on the annular shoulder block top of eccentric mount.
Directly secondary tuningout packing box is connected by flange with well head during the utility model use and gets final product.During tuningout, rotate eccentric mount and can position coarse adjustment, because a side periphery wall of the eccentric disc of packing box body bottom contacts with a side internal perisporium of eccentric mount, rotate the packing box body like this and just can realize accurate tuningout, precision can be controlled in 0.5mm; Thereby guaranteed packing box when work, be in the center of polished rod, the wearing and tearing that effectively alleviate packing improve sealing effectiveness, prolong packing_seal effective period.When pithead position appearance skew or the skew of oil pumper position, need not carry out the pine of flange and unload, only need the rotation packing box that it is accurately adjusted and get final product the labour intensity when having alleviated workman's tuningout.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing.
Accompanying drawing is that master of the present utility model looks cross-sectional view.
The specific embodiment
A kind of secondary tuningout packing box as shown in drawings, comprises the packing box body 6 and the flange 7 that are sleeved on the oil pumping polish rod 1, packing 2 is housed in its top, and packing 2 is the back taper packing, helps improving the polished rod seal effect.The bottom level of packing box body 6 is outwards expanded and is constituted an eccentric disc 4, and suit gland 3 outside packing box body 6 bottoms, and the bottom of gland 3 is pressed on eccentric disc 4 cards.On the lower, outer perimeter wall of gland 3 external screw thread is being set, gland 3 is eccentric mount 5 concave shape, that be sleeved on the oil pumping polish rod 1 by an external screw thread and a vertical section and links to each other.The aperture in the polished rod hole of eccentric mount 5 bottoms is less than the external diameter of eccentric disc 4, and eccentric disc 4 contacts with eccentric mount 5 bottom surfaces.In order to alleviate the wearing and tearing between eccentric disc 4 and eccentric mount 5 bottom surfaces, between eccentric disc 4 and eccentric mount 5 bottom surfaces packing ring 8 is being set, packing ring 8 is sleeved on the oil pumping polish rod 1.One side periphery wall of eccentric disc 4 contacts with a side internal perisporium of eccentric mount 5, like this, rotate eccentric mount 5 and can position coarse adjustment, because a side periphery wall of the eccentric disc 4 of packing box body 6 bottoms contacts with a side internal perisporium of eccentric mount 5, drive eccentric disc 4 when rotating packing box body 6 like this and in eccentric mount 5, rotate, just can realize accurate tuningout.The annular shoulder block of evagination is being set on the lower, outer perimeter wall of eccentric mount 5, and flange 7 is sleeved on the annular shoulder block top of eccentric mount 5, directly the utility model is connected by flange 7 with well head during use to get final product.
