Description
Technical field
The utility model relates to oil recovery machiner accessory technical field, more particularly to a kind of polished rod sealer.
Background technique
During oil exploitation, the pumping unit on ground drives downhole pump work by polished rod, sucker rod, with
Downhole crude is extracted into ground, in oil pumping process, polished rod ceaselessly pumps in well head, and in order to keep light
The sealing of annular space between bar and oil pipe, prevents crude oil from exosmosing, it will usually polished rod sealer be arranged at well head.
But as old well, stripper well increase, the complexity that the hole condition of rod-pumped well becomes, while well head touches the maintenance workers such as pump
Work amount increase, polished rod sealer have that poorly sealed, packing leakage is serious, not only increased the labor intensity of employee, but also
It polluted environment；And structure is complicated mostly for existing polished rod sealer, and dismounting is inconvenient, and replacement packing box is difficult.
Therefore it provides polished rod sealer a kind of being readily disassembled and excellent sealing performance is current those skilled in the art
The problem of member's urgent need to resolve.
Utility model content
In view of this, the present invention provides a kind of polished rod sealers, and structure is simple, easy to disassemble, are easy to packing
Box is replaced, and sealing performance is excellent.
To achieve the goals above, the utility model adopts the following technical solution:
A kind of polished rod sealer, including polished rod, the polished rod are mounted between sucker rod and polished rod eye, are pacified on the polished rod
Equipped with sealer, the sealer includes sealing shroud, clamp nut, gland, ball sealer, packing box, packing and pedestal；It is described close
The clamp nut is installed, the upper end of the clamp nut is provided with the gland, the pressure between big envelope and the polished rod
Lid is flexibly connected with the sealing shroud, and the lower part of the clamp nut is contacted with the ball sealer, rectangular under the ball sealer
At seal chamber, the packing box is placed in the seal chamber, the lower end of the packing box is the pedestal, the pedestal and institute
Sealing shroud is stated to be fixedly connected.
Preferably, the contact surface of the ball sealer and the sealing shroud is the conical surface.
Preferably, packing is equipped in the packing box.
Preferably, the packing is nylon rubber mixing sealed packing.
Preferably, the gland is threadedly coupled with the sealing shroud.
Preferably, gasket is also arranged on the polished rod, the gasket is between the packing and the packing box.
By taking above scheme, the beneficial effects of the utility model are:
1) it is threadedly coupled by gland with sealing shroud, screws gland, pressed clamp nut, and then press ball sealer, boring
Under the action of face, ball sealer is pressed down against packing box, the packing box extruding by sealing shroud simultaneously, in this way, not only making light
Rod sealer is integrally easy to disassemble, is easy to replace packing box, and form annular sealing strip, substantially increases sealing
Reliability, sealing performance is excellent；
2) by the gasket between packing and packing box, sealing performance is further enhanced.
It can be seen via above technical scheme that compared with prior art, the utility model discloses that provide a kind of polished rod close
Device is sealed, structure is simple, and it is easy to disassemble, it is easy to replace packing box, and sealing performance is excellent.
