Abstract
The utility model relates to an offset regulation positioning type polish rod sealing device, which comprises an outer box casing, a packing, a large head sleeve, an inner box, an oil sucking polish rod and a press cover, wherein the inner box, the packing and the large head sleeve are sequentially arranged in the outer box casing, the press cover is arranged on the outer box casing, and the oil sucking polish rod passes through the inner box, the packing, the large head sleeve and the press cover. The utility model adopts the double-box type automatic offset regulation structure, has the one-step offset regulation function during the installation, does not need the subsequent manual regulation, has the advantages of good sealing effect, no leakage without puncture, prevention of offset grinding of the rod and the pipe, service life prolonging, environment protection, convenient installation, convenient maintenance, convenient operation, time saving, labor saving and the like, and can be widely applied to well opening sealing engineering of sucker-rod oil wells in oil production.
Description
One, technical field
The utility model relates to oil exploitation sucker rod pumping well well mouth sealing device, particularly a kind of tuningout locate mode polished rod sealer.
Two, background technology
Traditional oil exploitation sucker rod pumping well well mouth sealing device, be generally packing is installed in the housing, by the structure that pressure cap compresses, the sucker rod pumping well well mouth sealing device of this structure, exist following shortcoming or deficiency: 1. do not possess the tuningout function, especially do not possess the automatic deflection adjusting function; 2. sealing effectiveness is bad, and Chang Fashengci leaks phenomenon, causes environment pollution; 3. lack application life, the maintain and replace workload is big.
Three, utility model content
Order of the present utility model provides a kind of tuningout locate mode polished rod sealer, adopts two box automatic deflection adjusting structures, the shortcoming or the deficiency that overcome effectively or avoid existing in the above-mentioned prior art.
Tuningout locate mode polished rod sealer described in the utility model comprises outer cassette shell body, packing, big headgear, inner box, oil pumping polish rod and gland.Described inner box, packing and big headgear are installed in the outer cassette shell body in turn, and gland is installed on the outer cassette shell body, and oil pumping polish rod passes inner box, packing, big headgear and gland.
Wherein, in the described inner box packing is installed, compresses by gland, seal mutually with oil pumping polish rod by big headgear.Described inner box and outer cassette shell body are movable the installation, leave annular space between its outer wall and the outer cassette shell body inwall.
The utility model has following advantage compared with prior art:
1, adopts two boxlike automatic deflection adjusting structures, have the function that gets final product disposable tuningout when installing, need not manually to adjust thereafter;
2, good sealing effect does not sting and does not leak, and promptly anti-stopping bar, pipe eccentric wear increase the service life, and protect environment again;
3, installation, maintenance, easy to operate saves time, laborsaving.
Four, description of drawings
Accompanying drawing is a kind of example structure schematic diagram of the present utility model;
Five, the specific embodiment
Consult accompanying drawing, a kind of tuningout locate mode polished rod sealer comprises outer cassette shell body 1, packing 2, big headgear 3, inner box 4, oil pumping polish rod 5 and gland 6.Inner box 4, packing 2 and big headgear 3 are installed in the outer cassette shell body 1 in turn, and gland 6 is installed on the outer cassette shell body 1, and oil pumping polish rod 5 passes inner box 4, packing 2, big headgear 3 and gland 6.
