The pressure cap is arranged at the top of the packing box, and the bottom of the packing box is connected with the universal joint; and the fence, the packing, the pressure cap, the fence, the filling and the spring are successively provided inside the packing box from down to up, the ball base connector and spherical sealing piece is arranged at the bottom of the universal joint, the bias pressure cap is arranged at the upper part of the ball base connector and the correctness device is arranged inside the cavity. The utility model has the function of adjustment and correctness, and is widely used in rod sealing process of oil pumping wells.
Description
One, technical field
The utility model relates to oil exploitation pumpingh well polish rod seal device, particularly a kind of oil-extractor polish-rod sealer.
Two, background technology
Traditional polish rod seal device, because pumping or eccentric wear of polished rod, usually damage packing box and packing, lose sealing function, influence the application life of sealed packing, produce the run, drip, leak phenomenon simultaneously, not only cause environment pollution, and increase workman's contribution intensity and cost of production.
Three, summary of the invention
The purpose of this utility model provides a kind of improved oil-extractor polish-rod sealer, shortcoming or deficiency that it can overcome effectively or avoid existing in the above-mentioned prior art, adopt universal joint, erection device structure, guarantee the concentricity of rod string and well head effectively, prevent eccentric wear, damage, increase the service life.
Oil-extractor polish-rod sealer described in the utility model, comprise pressure cap, spring, filler, jube, gland, packing box, universal joint, packing, tuningout pressure cap, spherical sealing element, erection device and ball joint, described packing box upper end is installed on pressure cap, the lower end is connected with universal joint, inside is installed on jube, packing, gland, jube, filler and spring from bottom to top in turn, described universal joint lower end is installed on ball joint and spherical sealing element, ball joint top is installed on the tuningout pressure cap, and inner chamber is installed on erection device.
Wherein, described universal joint is established central through hole in being, outer bottom is the structure of spheroid, and the spheroid bottom seals mutually with the spherical sealing element that the ball joint inner chamber is installed.Described erection device is the ball bearing that dual layer arrangement is installed spherical pellet shot from a slingshot about in the of.Described ball joint lower end is the clip head, and the upper end is the structure of tubular, and its inner chamber is installed on spherical sealing element.Described spherical sealing element is interior spherical structure.
The utility model has following advantage compared with prior art:
1, adopt compound error-correction structures such as universal joint, centralizer, sealing performance is distinguished, and anti-eccentric wear effect is superior, effectively avoids the destruction to sealing, prolongs its application life, reduces use cost;
2, avoided the run, drip, leak of well head effectively, problem of environment pollution caused has reduced the economic loss of enterprise;
3, alleviate labor intensity of operating personnel, raise the management level.
Four, description of drawings
Accompanying drawing is the utility model structural representation.
Five, the specific embodiment
Consult accompanying drawing, a kind of oil-extractor polish-rod sealer, comprise pressure cap 1, spring 2, filler 3, jube 4, gland 5, packing box 6, universal joint 7, packing 8, tuningout pressure cap 10, spherical sealing element 11, erection device 12 and ball joint 13, packing box 6 upper ends are installed on pressure cap 1, the lower end is connected with universal joint 7, inside is installed on jube 9, packing 8, gland 1, jube 4, filler 3 and spring 2 from bottom to top in turn, universal joint 7 lower ends are installed on ball joint 13 and spherical sealing element 11, ball joint 13 tops are installed on tuningout pressure cap 10, and inner chamber is installed on erection device.
Universal joint 7 is established central through hole in being, outer bottom is the structure of spheroid, and the spheroid bottom seals mutually with the spherical sealing element 11 that ball joint 13 inner chambers are installed.Erection device 12 is the ball bearing that dual layer arrangement is installed spherical pellet shot from a slingshot about in the of.Ball joint 13 lower ends are the clip head, and the upper end is the structure of tubular, and its inner chamber is installed on spherical sealing element 11.Spherical sealing element 11 is interior spherical structure.
