Description

A kind of polished rod sealer
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- The conical surface, 9- gaskets.
Specific implementation mode
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete Site preparation describes, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other Embodiment shall fall within the protection scope of the present invention.
As shown in Figure 1, the embodiment of the invention discloses a kind of polished rod sealer, including polished rod 1, polished rod 1 is mounted on oil pumping Between bar and polished rod eye, sealer is installed on polished rod 1, sealer include sealing shroud 2, clamp nut 3, gland 4, ball sealer 5, Packing box 6, packing and pedestal 7;Clamp nut 3 is installed, the upper end of clamp nut 3 is provided with pressure between sealing shroud 2 and polished rod 1 Lid 4, gland 4 are flexibly connected with sealing shroud 2, and the lower part of clamp nut 3 is contacted with ball sealer 5, and the lower section of ball sealer 5 forms sealing Chamber is placed with packing box 6 in seal chamber, and the lower end of packing box 6 is pedestal 7, and pedestal 7 is fixedly connected with sealing shroud 2.By this hair Bright gland 4 is threadedly coupled with sealing shroud 2, screws gland 4, clamp nut 3 is pressed, and then press ball sealer 5, in the conical surface 8 Under effect, ball sealer 5 is pressed down against packing box 6, and packing box 6 is simultaneously by the extruding of sealing shroud 2, in this way, not only so that light Rod sealer is integrally easy to disassemble, is easy to replace packing box 6, and form annular sealing strip, substantially increase close The reliability of envelope, sealing performance are excellent.
Specifically, the contact surface of ball sealer 5 and sealing shroud 2 is the conical surface 8.
Specifically, being equipped with packing in packing box 6.
Specifically, packing is nylon rubber mixing sealed packing.
Specifically, gland 4 is threadedly coupled with sealing shroud 2.
Specifically, being also arranged with gasket 9 on polished rod 1, gasket 9 is between packing and packing box 6.
The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention.The technology of the industry Personnel are it should be appreciated that the present invention is not limited to the above embodiments, and the above embodiments and description only describe this The principle of invention, without departing from the spirit and scope of the present invention, various changes and improvements may be made to the invention, these changes Change and improvement all fall within the protetion scope of the claimed invention.
