Technical characterictic of the present utility model is: multifunctional oil-extractor wellhead polish rod sealing device, by anti-eccentric wear assembly, antifouling assembly, compression assemblies, bulb assembly and fixation kit constitute, it is characterized in that described anti-eccentric wear assembly is by pressure cap (1), baffle plate (2), slide block (3), first spring (4), nut (5) and fluorine cushion rubber (15) are formed, wherein slide block (3) is trapezoidal, its inclined-plane is provided with an elongate recesses slideway (16), its vertical plane is provided with two rectangular recess (17), one end of first spring (4) is put into wherein, described fluorine cushion rubber (15) is tubular, and the outer ring is provided with screw thread (14); Described antifouling assembly is made up of spray-proof ball (6), second spring (7), baffle plate (8), and wherein second spring (7) one ends and spray-proof ball (6) join, and the other end is against baffle plate (8), and the oblique angle of itself and horizontal plane is between 10 ° to 20 °; Described compression assemblies is made up of pressure-conducting disk root piece (9) and packing (11); Described bulb assembly is made up of bulb adapter sleeve (12) and steering ball end (13), and wherein steering ball end (13) is the bulb shape, hollow, and sucker rod (10) passes therethrough.
The utility model has the advantages that simple in structure, easy to adjust, safe and reliable, the operating efficiency high pollution is little, can prolong the application life of equipment greatly, saves the maintenance time and the expense of equipment, have considerable economic and social benefit, can extensively on oil-field oil pumper, promote the use of.
Four, description of drawings
Accompanying drawing 1 is an overall structure schematic diagram of the present utility model
Accompanying drawing 3 is steering ball end structural representations of the present utility model
Wherein: 1, pressure cap 2, baffle plate 3, slide block 4, first spring 5, nut 6, spray-proof ball 7, second spring 8, baffle plate 9, pressure-conducting disk root piece 10, sucker rod 11, packing 12 bulb adapter sleeves 13, steering ball end 14, screw thread 15, fluorine cushion rubber 16, slideway 17, groove
Five, the specific embodiment
In conjunction with the accompanying drawings 1, Fig. 2 and Fig. 3 be further described embodiment, present embodiment is to be used for illustrating of the present utility model, rather than the utility model is carried out any restriction.
Multifunctional oil-extractor wellhead polish rod sealing device is made of anti-eccentric wear assembly, antifouling assembly, compression assemblies, bulb assembly and fixation kit, it is characterized in that described anti-eccentric wear assembly is made up of pressure cap 1, baffle plate 2, slide block 3, first spring 4, nut 5 and fluorine cushion rubber 15, wherein slide block 3 is trapezoidal, its inclined-plane is provided with an elongate recesses slideway 16, its vertical plane is provided with two rectangular recess 17, one end of first spring 4 is put into wherein, described fluorine cushion rubber 15 is tubular, and the outer ring is provided with screw thread 14; Wherein said antifouling assembly is made up of spray-proof ball 6, second spring 7, baffle plate 8, wherein second spring, 7 one ends and spray-proof ball 6 join, and the other end is against baffle plate 8, and the oblique angle of itself and horizontal plane is between 10 ° to 20 °, polished rod does not exist, and spray-proof ball 6 is sealed well head under the effect of second spring 7; Described compression assemblies is made up of pressure-conducting disk root piece 9 and packing 11; Described bulb assembly is made up of bulb adapter sleeve 12 and steering ball end 13, and wherein steering ball end 13 is the bulb shape, hollow, and sucker rod 10 passes therethrough.
Multifunctional oil-extractor wellhead polish rod sealing device is installed in the well head upper end, pressure cap 1 is outwarded winding, slide block 3 symmetries are put into, open nut 5 from the side, put into first spring 4 again, making the one end stretch into slide block 3 vertical planes is provided with in two rectangular recess 17, close nut 5 after compressing, whether viewing hood 2 is at correct position again, screw pressure cap 1 after the adjustment, sucker rod 10 stretches into, and making it be close to elongate recesses slideway 16 on slide block 3 inclined-planes, sucker rod 10 is when moving up and down, because the elastic force effect of first spring 4 makes slide block 3 be close to sucker rod 10, do not make it inclined to one side, make the suitable also locking in gap of sucker rod 10 and multifunctional oil-extractor wellhead polish rod sealing device can prevent inclined to one side simultaneously yet by fluorine cushion rubber 15 by adjusting sucker rod 10 location guiding mechanisms; The position of the steering ball end 13 of rod packing 11 being housed in the middle of adjusting according to the gradient of sucker rod 10, and screw bulb adapter sleeve 12 and fixed; Rod packing on the steering ball end 13 11 adapter sleeves are tightened, can be entered duty.
When needs are changed rod packing 11, coincide being advanced to sucker rod 10 by piston, threaded rod with the rod packing 11 of sucker rod 10 1 side-to-side anastomosis in the sucker rod 10 locking seal valves, sealing sucker rod 10 following spaces, cut off the well head transmission that upwards pressure, can change the axial pressure-conducting disk root piece 9 on the steering ball end 13 easily.
