Abstract
The utility model relates to a universal combined sealer comprising a hollow-type ball body and a ball seat which can be arranged into a dynamic rod body, wherein the ball body is located in the ball seat; the outer diameter of the ball body is matched with the inner diameter of the ball seat; the ball seat is provided with a sealing part used for sealing the part between the ball seat and the ball body; and the outside of the ball seat uses a pressure cover to fix the ball body. The universal combined sealer adopts the combination of a universal ball-type structure and a sealing packing group, and avoids the non-vertical or non-horizontal or transverse eccentric movement state of a pumping rod or other dynamic rod bodies from causing deviated wear leakage. The universal combined sealer can greatly reduce the repairing times of necessariness of stopping production to replace the worn sealing packing, and improve production efficiency and economic benefit.
Description
[technical field]
The utility model relates to the universal combination seal device of sucker rod in the industrial pumping unit such as a kind of seal arrangement, particularly oil, chemical industry etc. and other dynamic bodies of rod.
[background technique]
The sucker rod in the existing petroleum industry in the pumping unit of extensive use and the seal arrangement of other dynamic bodies of rod, its structure is to be with stuffing box on the top of the dynamic body of rod, seal with rubber packing group in the stuffing box, external application sealed pressing sleeve and pressure cap are fixed, and the bottom of sealed pressing sleeve seals with rubber packing group.When the sucker rod of this seal arrangement requirement pumping unit or other dynamic bodies of rod move, must keep horizontal or vertical state, can not be offset.But in the practice, can't accomplish at all under many circumstances that the skew of dynamic rod member often causes the wearing and tearing seepage with sealed packing during owing to work.This is the ubiquitous phenomenon in present related domain.
[summary of the invention]
Technical problem to be solved in the utility model is to overcome existing defective in the above-mentioned prior art, and a kind of sucker rod and universal combination seal device of other dynamic bodies of rod of new structure is provided.
The utility model has adopted following technical proposal to solve its technical problem: a kind of universal combination seal device, it is characterized in that: it comprises hollow type spheroid 10 and the ball seat 14 that can insert the dynamic body of rod 13, spheroid is located in the ball seat, the external diameter of spheroid matches with the internal diameter of ball seat, is being equipped with on the ball seat in order to the Sealing between sealed ball seat and the spheroid 12; Ball seat external application gland 11 is spheroid fixedly.
The utility model compared with prior art has tangible advantage and good effect.The utility model has adopted the universal ball structure to combine with the sealed packing group, the deflection wearing and tearing seepage that the out-of-level or horizontal motion state prejudicially of out of plumb of avoiding sucker rod or other dynamic bodies of rod causes Sealing.When the utility model also utilizes one or two or plural spheroid to interlock, center line can keep horizontal or vertical horizontal parallel mobile principle, make the sealed packing group and the moving direction of the dynamic body of rod remain plumbness, avoided sealed packing or the dynamic eccentric wear and the seepage that cause of the body of rod, especially can significantly reducing to stop production changes the repairing number of times of the sealed packing that is worn, and manufacturing efficiency and economic benefit are provided.

[embodiment]
The utility model will be further described below in conjunction with embodiment and accompanying drawing.
Embodiment 1: see Fig. 3.Spheroid 10 is a hollow type with ball seat 14, and spheroid is located in the ball seat, seals with ball seal spare 12 between spheroid and the ball seat.Ball seal spare 12 is fixed on the ball seat.Ball seat external application gland 11 is fixing.Spheroid top is fixing by lock screw 5.During use, spheroid is enclosed within on the external diameter of sealed pressing sleeve 4, and spheroid partly is positioned at the outer path position of rubber packing group 9.
The utility model can have two covers or the above ball-type seal arrangement of two covers.On the basis of said mechanism, the top of the spheroid 10 of the second cover ball-type seal arrangement is ball seat, and spheroid 7 is located in the ball seat of spheroid 10, seals with ball seal spare 8 between the ball seat of spheroid 7 and spheroid 10; Spheroid 7 external application glands 6 are fixing.The structure of the ball-type seal arrangement that two covers are above by that analogy.Embodiment 2 is two cover ball-type seal arrangements, sees Fig. 1.On embodiment 1 basis, the top of spheroid 10 is ball seat, and spheroid 7 is located in the ball seat of spheroid 10, seals with ball seal spare 8 between the ball seat of spheroid 7 and spheroid 10; Spheroid 7 external application glands 6 are fixing.Sealing is fixed on the ball seat.
Embodiment 3: see Fig. 4.The shape of spheroid is pancake part spheroid.Sealing 8 is fixed on the spheroid.
Sealing described in the utility model or be fixed on the spheroid, or be fixed on the ball seat, or be fixed between spheroid and the ball seat.
The utility model in use, spheroid and ball seat are positioned at outside sealed pressing sleeve 4 and the dynamic rod member 13, the top of spheroid is fixing with sealed pressing sleeve 4 by lock screw 5, the spheroid part just in time is positioned at outside the rubber packing group 9.When dynamic body of rod out of plumb or out-of-level motion, spheroid can rotate freely in ball seat thereupon.Packing in spheroid and its ball is remaining plumbness with the moving direction of the dynamic body of rod, has so just avoided the dynamic body of rod packing group to be caused the wearing and tearing seepage of deflection.When the center line of the dynamic body of rod produces when traversing, spheroid still keeps vertical with the body of rod with the packing group, and not only spheroid at this moment rotates in ball seat thereupon, and in ball seat also with stressed effect rotary oscillation.The internal diameter of spheroid and the dynamically gap between the body of rod at this moment promptly are the range of movement that the dynamic body of rod can laterally move.
