Description

Oil field pipeline plug

Technical Field

The utility model relates to an oilfield equipment field relates to an oil field pipeline plug particularly.

Background

The oil field pipeline plug is arranged at the tail end of the oil field underground pipeline, so that leakage of the oil field underground pipeline is prevented, and the effect of sealing the oil field pipeline is achieved. The existing oilfield pipeline plug is designed more traditionally, only is a threaded column with a bolt head, is screwed at the tail end of an oilfield underground pipeline by using a wrench, and is connected by threads, so that the existing oilfield pipeline plug is often poor in sealing performance and easy to leak oil. Although the sealing performance is temporarily improved by simply arranging the sealing gasket on the oil field pipeline plug, the underground environment of the oil field is complex due to no protection of the outside, the sealing gasket is short of the sealing performance quickly, the oil leakage of the oil field pipeline is caused, and the service life of the existing oil field pipeline plug is short.

SUMMERY OF THE UTILITY MODEL

The utility model discloses the main technical problem who solves provides an oil field pipeline plug, sets up sealed the pad with oil field pipeline end-to-end connection face in the pit, has good leakproofness, and the outside sets up sealed dustcoat moreover, has improved the protection to sealed department, has increased plug life.

In order to achieve the above object, the present invention provides the following technical solutions:

this oil field pipeline plug includes columniform screw thread post, screw thread post tip is equipped with the end cover of disc perpendicularly, the end cover tip is equipped with the columniform turning handle perpendicularly, the screw thread post, the end cover, the turning handle is all coaxial, the diameter of turning handle is less than the diameter of screw thread post and is less than the diameter of end cover, open the turning handle side has the inserted bar hole, the end cover is equipped with the round towards screw thread post one side and seals up the pad, the outside cover of end cover has the sealed dustcoat of cylinder, the inside screw thread inner tube that is equipped with the round pipe form of sealed dustcoat, the screw thread inner tube inner wall is attacked there is the concave screw thread, the convex screw thread is.

As a further optimization of the technical scheme, the threaded column, the end cover and the rotating handle are all made of stainless steel, and the threaded column, the end cover and the rotating handle are all of an integral structure.

As a further optimization of the technical solution, the sealing gasket is made of corrosion-resistant rubber material, and the sealing gasket is connected with the end cover through an adhesive.

As a further optimization of the technical scheme, the sealing outer cover and the threaded inner pipe are both made of stainless steel, and the sealing outer cover and the threaded inner pipe are of an integral structure.

As a further optimization of the technical scheme, after the threaded inner pipe is screwed with the end cover, the end cover and the rotating handle can be completely wrapped by the sealing outer cover.

The beneficial effect of adopting above technical scheme is: when the oilfield pipeline plug is used, the threaded column is screwed with the concave thread of the pipeline in the oilfield well, and the rod-shaped tool is inserted into the inserting rod hole to rotate the rotating handle, so that the threaded column is driven to be screwed, the sealing gasket of the end cover is tightly attached to the end surface of the oilfield pipeline, and the oilfield pipeline is sealed and plugged. And finally, sheathing the end cover and the rotating handle with a sealing outer cover, and screwing the threaded inner pipe on the end cover to protect the sealing position of the pipe plug on the oilfield pipeline. This oil field pipeline plug sets up sealed the pad with oil field underground pipe end connection face, has good leakproofness, and the outside sets up sealed dustcoat moreover, has improved the protection to sealed department, has increased plug life.

Detailed Description

The following describes in detail the preferred embodiments of the oilfield tubular plug of the present invention with reference to the accompanying drawings.

Fig. 1 and fig. 2 show the specific implementation of the oil field pipe plug of the present invention:

combine fig. 1 and fig. 2, this oil field pipeline plug includes columniform

screw thread post

1, 1 tip of screw thread post is equipped with disc-shaped end cover 2 perpendicularly, 2 tip of end cover are equipped with columniform turning handle 3 perpendicularly, screw thread post 1, the end cover 2, turning handle 3 is all coaxial, the diameter that the diameter of turning handle 3 is less than screw thread post 1 is less than end cover 2's diameter, 3 side openings of turning handle have a peg hole 7, end cover 2 is equipped with round sealed pad 4 towards screw thread post one side, 2 outside covers of end cover have the sealed dustcoat 5 of cylinder, sealed dustcoat 5 is inside to be equipped with the tubular threaded inner tube 6 of round, the concave screw thread has been attacked to the 6 inner walls of threaded inner tube, the convex screw thread has been attacked to the 2 outer walls of end cover, threaded.
