Abstract
The utility model relates to a rod or shaft sealing device capable of regulating eccentric wear, which comprises a stuffing box, a packing set and a press cover, the packing set is installed in the stuffing box, the press cover is connected with one end of the stuffing box; the other end of the stuffing box is connected with a connecting sleeve through threads. After the utility model adopts the technical scheme, because the stuffing box is connected with the connecting sleeve by threads, at the time of tightening the packing set, the stuffing box, the packing set and the press cover can be rotated synchronously; thus, the eccentric wear position of the packing set can be rotated with a definite angle, and the wear (namely the eccentric wear) between a sucker rod and the surface an upper end hole (namely a central hole of the press cover) of the stuffing box and between the sucker rod and the inner surface of a lower end hole of the stuffing box due to the eccentric wear of the same positions for a long time can be avoided. The packing set tightening and the eccentric wear regulation are completed simultaneously, and the independent regulation of eccentric wear is not needed; thus, the service life of the sealing device is extended and the production efficiency is improved.
Description
Technical field
The utility model relates to a kind of bar of motion or the sealing device between axle and the stationary gantry, specifically is a kind of bar or shaft seal of adjusting eccentric wear.
Background technology
The machine of using often relates to the sealing device between static casing and the working beam of motion (axle) in industrial production, for example: pumpingh well wellhead sealing device in the oil exploitation.This sealer is installed on the well head, at work, after adjusting oil pumper level or job execution, sucker rod and stuffing box decentraction are caused in the capital, this decentraction can cause the contact surface between sucker rod and the stuffing box to produce steel and steel friction, can cause polished rod and stuffing box to be ground away simultaneously, the packing quick abrasion can seal incessantly when serious.In order to keep sucker rod and stuffing box concentric, need stop oil pumper work, adjust oil pumper or well head so as to make sucker rod and stuffing box concentric, unusual trouble not only, but also need often quit work influences operating efficiency.
Summary of the invention
The purpose of this utility model just provides a kind of bar or shaft seal of adjusting eccentric wear, to solve the concentric trouble of adjustment sucker rod that prior art exists and stuffing box and the problem of operating efficiency influence.
The technical scheme that the utility model is taked is: comprise stuffing box, packing and gland, packing is contained in the stuffing box, and gland is connected an end of stuffing box, and the other end of described stuffing box and an adapter sleeve are by being threaded.
Described gland and stuffing box are by being threaded.
Described stuffing box and gland are structure as a whole.
On the contact surface of described adapter sleeve and packing, be provided with flange.
After adopting technique scheme, be threaded owing to adopt between stuffing box and the adapter sleeve, so when tight packing, stuffing box, packing and gland be rotation synchronously, so just make the certain angle of packing eccentric wear rotated position, avoided causing the abrasion (being eccentric wear) of the inner face of the upper end hole (that is centre bore of gland) of sucker rod and stuffing box and following stomidium because of the long-time same orientation of eccentric wear.Tight packing is finished simultaneously with adjusting eccentric wear, need not to adjust separately eccentric wear again, has prolonged the application life of sealing device, has improved production efficiency.
Description of drawings
Fig. 1 is the axial cross-sectional schematic of the utility model general structure.
The specific embodiment
Comprise stuffing box 1, packing 2, gland 3, adapter sleeve 4 referring to Fig. 1, the utility model, on adapter sleeve 4 and packing 2 contact surfaces, be provided with flange 5.Stuffing box 1 adopts with gland 3 and is threaded or integrative-structure, and packing 2 is contained in the stuffing box 1, and stuffing box 1 adopts with adapter sleeve 4 and is threaded.
Adapter sleeve 4 and packing 2 contact surface upper flanges 5 have increased the contact area with packing 2, thereby strengthen the sealing of contact surface and packing 2.
The same with common stuffing seal, when using the utility model, keep sealing in order to make it, just need compress packing 2 at set intervals.Because gland of the present utility model 3 and stuffing box 1 are one or can be fastening in advance, at tight packing 2 stuffing box 1, packing 2 and gland 3 are rotated synchronously, so just make their eccentric wear orientation transposition, prevented the generation of eccentric wear, realized that tight packing adjusted eccentric wear simultaneously again.
