Structural representations of the Fig. 5 for four jigsaw splits in the utility model embodiment after into a single integrated structure.
Fig. 6 is the partial enlarged drawing for the groove being opened in the utility model embodiment on cylinder.
Embodiment
Below in conjunction with brief description of the drawings specific embodiment of the present utility model.As shown in Figures 1 to 6：One kind is applied to
The sealer under pressure of oil-gas pipeline, including a hollow cylinder 1, four supports 2 are provided with one end of cylinder 1, this four
Individual support 2 is uniformly distributed in a circumferential direction, and rotational support has a jigsaw 3 on each support 2, and this jigsaw 3 is overall
In isosceles right triangle shape, and the middle part of jigsaw 3 is hard, and its both sides is then flexible rubber portion 13, and this two
Individual flexible rubber portion 13 is also right-angle triangle, while flexible rubber portion 13 is hollow-core construction, at the right angle of each jigsaw 3
Sealing strip 4 is both provided with side where side, and sealant 5 is additionally provided with the upper surface of jigsaw 3, above-mentioned four jigsaw
3 can be spliced into a square jointly, and this square side is the hypotenuse of each jigsaw 3,
Rope 6 is both provided with the apex of each jigsaw 3, the other end of all ropes 6 is all commonly connected to a drawing
On ring 7, after above-mentioned draw ring 7 passes through the inner chamber of cylinder 1, hang down naturally outside cylinder 1, and described hanger bracket 8 is then arranged on cylinder
On the outer wall of body 1, and the groove 9 that can accommodate rope 6 is provided with the inwall of cylinder 1 and top；
External screw thread is provided with the outer wall of cylinder 1, is mutually furnished with the upper lid 10 being threadedly coupled with it with the outer wall of cylinder 1,
And sealant 5 is again provided with the bottom face of upper lid 10, tightening nut 11 is fixedly connected with the top of upper lid 10, and
And tightening nut 11 is equally threadedly coupled between cylinder 1, the inwall of cylinder 1 is provided with internal thread, matches with the inside of cylinder 1
There is the sealing bolt 12 being threadedly coupled with it, and sealant 5 is also equipped with the lower surface of the nut portion of sealing bolt 12.
A kind of course of work of sealer under pressure applied to oil-gas pipeline of the utility model embodiment is as follows：Need
When carrying out non-stop plugging to the leakage point of oil-gas pipeline, the front end (one end for carrying jigsaw 3) of present apparatus cylinder 1 is passed through first
Leakage point, which is inserted in oil transportation or air delivering pipeline, (if leakage point is smaller, will leak out using instrument and expands into can allow this dress
Put the size of insertion), because cylinder 1 is hollow, therefore medium can be discharged by the inner cylinder of cylinder 1 during insertion,
This mode can allow the present apparatus to be smoothly inserted into pipeline, during jigsaw 3 enters pipeline, each both sides of jigsaw 3
Hollow flexible rubber portion 13 deformed under the squeezing action of pipeline, that is to say, that the overall width of jigsaw 3 is greater than
The width of leakage point, it can so ensure that square that jigsaw 3 is spliced can will leak out from below and a little be completely covered, so as to
Ensure plugging effect；
After all jigsaw 3 all enter the inside of pipeline, operating personnel, which pull up, pulls ring 7, is allowed by rope 6 all
Jigsaw 3 overturn, four jigsaw 3 are mutually spliced into a complete square, and the square area is more than the face of leakage point
Product, therefore can completely will leak out and a little block from below, while the sealing strip 4 at the right-angle side of four jigsaw 3 also contacts with each other
And extrude, the square interior for preventing from being put together leaks, above-mentioned complete square in the presence of the pressure in pipeline
Shape can apply pressure from the bottom to top to the pipeline at leakage point, due to being both provided with sealant 5 in the upper surface of each jigsaw 3,
Therefore in the presence of this positive pressure, the closure from the inside to the outside to leakage point is realized；
Then upper lid 10 is threaded on cylinder 1, rotates tightening nut 11 using instruments such as spanners, lid 10 in drive
In the up-downgoing of cylinder 1, until the sealant 5 on the upper bottom face of lid 10 is pressed at leakage point, realize to leakage point from outside to inside
Closure；
Finally, sealing bolt 12 is tightened in cylinder 1, the sealant 5 allowed on the nut portion lower surface of sealing bolt 12
It is pressed on the upper surface of cylinder 1, prevents the medium in pipeline from being revealed from the inner wall part of cylinder 1；
Finally tightening nut 11 and sealing bolt 12 are welded on cylinder 1, that is, completed for some leakage point
Non-stop plugging operates.
