Detailed Description
The present invention will be further explained with reference to the accompanying drawings:
as shown in fig. 1-3, the pipeline plugging device for oil exploitation consists of a conical plug body 1, a plug body pull column 2, a fixing sleeve 3 and a screwing sleeve 5;
the center of the bottom surface of the conical plug body 1 is connected with a plug body pull column 2, the plug body pull column 2 and the conical plug body 1 are integrally connected through mold forming, the plug body pull column 2 and the conical plug body 1 have certain deformation, preferably, rubber materials are adopted, a fixing sleeve 3 is fixedly sleeved on a bottom column body of the plug body pull column 2, an external screwing thread is arranged on the outer side sleeve surface of the fixing sleeve 3, and the fixing sleeve 3 is screwed with a screwing sleeve 5 through the external screwing thread;
the fixed cover is equipped with on the outside mantle surface of rotary joint cover 5 and presses and to establish turn-button 7, presses the top surface fixed mounting who establishes turn-button 7 and presses the clamping ring wall 6, and fixed external member 3 sets up in the intra-annular of clamping ring wall 6, and the bottom fixed mounting of fixed external member 3 has terminal turn-button 4, and terminal turn-button 4 is through the slow rotation that drives fixed external member 3 to realize cock body pull column 2 and the rotation of centrum toper cock body 1, thereby get into the small opening of pipeline.
In the present embodiment, the fixing sleeve 3 is fixedly mounted with the plug body 2 by a cap screw 10, and the end turn knob 4 is mounted with the fixing sleeve 3 by a screw.
In this embodiment, the conical plug body 1 is provided with a conical helical tooth 8 on the outer conical surface, and the conical helical tooth 8 is integrally connected with the conical plug body 1.
In this embodiment, a pressure ring pad 9 is fixedly installed on the top ring edge of the pressure ring wall 6, and the pressure ring pad 9 is used for pressure buffering between the pipeline and the pressure ring wall 6.
In the structure, the conical plug body 1 with proper size is selected according to the size of a leakage hole of an oil pipeline, the bottom surface of the conical plug body 1 is larger than the diameter of the leakage hole, the conical head of the conical plug body 1 is plugged into the leakage hole, then the tail end knob 4 is rotated, so that the plug body pull column 2 and the conical plug body 1 are driven to slowly rotate and are jacked, the tail end of the conical plug body 1 is extruded and deformed to enter the leakage hole, and at the moment, the conical plug body 1 is completely immersed into the leakage hole and then enters the inside of the pipeline;
the knob 7 is established to the pressure of rotation, holds terminal knob 4 for fixed external member 3 and 5 relative rotations that take place of cup joint, thereby produce the displacement, and the clamping ring wall 6 is pressed down on establishing the pipeline lateral wall under the effect of displacement, and until the bottom surface roof pressure of toper cock body 1 covers the hole edge of small opening, under the pressure of inside oil pressure and outside clamping ring wall 6, the small opening is stopped up from the inside, and the effect is better.
Having shown and described the basic principles, essential features and advantages of the invention, it should be understood by those skilled in the art that the present invention is not limited by the foregoing embodiments, which are merely illustrative, but rather are intended to cover various changes and modifications within the spirit and scope of the invention as defined by the appended claims.
