The gluing wing is fixed；The connecting rod lower end is provided with ball-type articulated joint；The bottom plug includes the lower glue wing of multiple concatenations；Institute
Ball-type articulated joint is stated to be hinged in the lower glue wing ball-type hinge cavity at top；The bottom plug is internally provided with overflow valve.
Further, the gluing wing is a, and the lower glue wing is a.
Further, the overflow valve includes valve body, valve chamber, spool, spring and spout hole；It is opened at the top of the valve body
Equipped with ball-type hinge cavity, the lower part of the valve body offers valve chamber, and the spool is arranged by spring in the valve chamber, described
Spout hole is connected to the valve chamber.
Further, the valve body is the intermediate cylindrical structure with round platform, and the lower glue wing at the top is arranged in centre

Further, the spout hole is opened on the intermediate round platform.
Further, the connecting rod and the material of overflow valve are abrasion-resistant stee.
The utility model generate advantageous effect be：
The completion rubber plug of the utility model can adaptively adjust the angle, good airproof performance, automatic leakage according to the trend of well casing
Pressure improves cementing quality and speed of application.
Description of the drawings
Fig. 1 is the structural schematic diagram of the device of the utility model；
Main appended drawing reference explanation：
1- locking nuts, 2- gaskets, 3- glue the wing, 4- connecting rods, 5- ball-type articulated joints, 6- thread spacers, the glue wing under 7-,
8- valve bodies, 9- spout holes, 10- valve chambers, 11- springs, 12- spools.
Specific implementation mode
The preferred embodiment of the utility model is described further below in conjunction with the accompanying drawings, drawings and examples are only to this
The technical solution of the explanation of utility model, this practicability type is not limited to content described in drawings and examples.
A kind of completion rubber plug, including top cement plug and bottom plug；The top cement plug is hinged with bottom plug；The top cement plug includes
The gluing wing 3 of multiple concatenations, the gluing wing 3 are intermediate open-celled structure, and centre wears connecting rod 4；The top of the connecting rod 4
It is fixed by gasket 2 and locking nut 1 and the gluing wing 3 at top；The lower part of the connecting rod 4 passes through external screw thread and thread spacer
6 fix with the gluing wing 3 of bottom；4 lower end of the connecting rod is provided with ball-type articulated joint 5；The bottom plug includes multiple strings
The lower glue wing 7 connect；The ball-type articulated joint 5 is hinged in the 7 ball-type hinge cavity of the lower glue wing at top；Setting inside the bottom plug
There is overflow valve.
Specifically, the gluing wing 3 is 3, the lower glue wing 7 is 2.
Specifically, the overflow valve includes valve body 8, valve chamber 10, spool 12, spring 11 and spout hole 9；The valve body
8 top offers ball-type hinge cavity, and the lower part of the valve body 8 offers valve chamber 10, and the spool 12 is arranged by spring
In the valve chamber 10, the spout hole 9 is connected to the valve chamber 10.
Specifically, the valve body is the intermediate cylindrical structure with round platform, the lower glue wing 7 at the top is arranged in centre
The lower glue wing 7 on the top of round platform, the bottom is arranged in the lower part of intermediate round platform.
Specifically, the spout hole 9 is opened on the intermediate round platform.
Specifically, the connecting rod 4 and the material of overflow valve are abrasion-resistant stee.
The completion rubber plug use process is as follows：As shown in Figure 1, to precalculated position under rubber plug is placed in pipe string, with top
Pushing Self-locking rubber cork for liquid makes its downlink, and when rubber plug enters lower curved section, the adaptive adjustment angle of upper and lower rubber plug is realized smoothly logical
Tilting section is crossed, when end pressure is more than replacement hydraulic coupling under rubber plug, overflow valve opens pressure release, and rubber plug continues traveling downwardly, when rubber plug arrives
