Description
Technical field
The present invention relates to oil recovery machiner accessory technical field, especially a kind of polished rod sealer.
Background technology
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 of the hole condition change of rod-pumped well, 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 existing polished rod sealer is mostly complicated, and dismounting is inconvenient, and it is difficult to replace packing box.
Therefore it provides polished rod sealer a kind of being readily disassembled and excellent sealing performance is current people in the art
The problem of member's urgent need to resolve.
Invention content
The purpose of the present invention is:A kind of polished rod sealer is provided, it is simple in structure, it is easy to disassemble, it is easy to carry out packing box
It replaces, and sealing performance is excellent.
To achieve the goals above, the technical solution adopted by the present invention is as follows:
A kind of polished rod sealer, including polished rod, the polished rod are mounted between sucker rod and polished rod eye, pacify 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 invention are as follows:
1) it is threadedly coupled with sealing shroud by gland, screws gland, pressed clamp nut, and then press ball sealer, boring
Under the action of face, ball sealer is pressed down against packing box, and packing box is squeezed by sealing shroud simultaneously, in this way, not only so that 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.
Description of the drawings
Fig. 1 is a kind of overall structure sectional view of polished rod sealer of the present invention.
In figure:1- polished rods, 2- sealing shrouds, 3- clamp nuts, 4- glands, 5- ball sealers, 6- packing boxs, 7- pedestals, 8-
