Gas transmission line pipeline pipe end plugging device
Technical field
The invention belongs to gas transmission line blocking technology fields, and in particular to gas transmission line pipeline pipe end plugging device.
Background technique
Currently, the method used when gas transmission line needs to block is to inflate blocking pipeline with rubber pneumatic bag, brick, water are then used
Mud is built a wall closure.This method is disadvantageous in that, when closure can not detect gas, air pressure real time status in pipeline, exists
Security risk.And take a lot of work when being built a wall using brick, cement, take material, construction site excavate Space-Work amount it is big;Rear gasbag of building a wall is not allowed
Easily take out;Occluding body is easy leakage gas after closure.
Summary of the invention
The present invention is to solve the problems, such as that prior art closure of building a wall exists, and providing one kind can detecte air in pipeline air pressure
The gas transmission line pipeline pipe end plugging device of real time status.
The present invention in order to solve the problems existing in the prior art, is adopted the technical scheme that:
Gas transmission line pipeline pipe end plugging device, including stifled, attachment device and detection mouth are held, its main feature is that: the end is stifled
Including holding stifled inner ring, holding stifled outer ring and closure plate, the end blocks up inner ring and holds stifled outer ring and closure plate affixed, formed and accommodate pipe end
Annular groove, in use, be placed in sealing material in a ring groove, will end is stifled is fastened on pipe end, the connecting plate, one end is logical
It crosses the stifled fixing bolt in end to connect with the stifled outer ring in the end, the other end is connect by connecting bolt with fixed plate, and the fixed plate is solid
It is connected on the duct wall, the via hole for offering on the side wall of outer ring and holding stifled fixing bolt cooperation, the connecting plate are blocked up in the end
On offer with the screw buckle of fixing bolt cooperation and with the via hole that connect bolt and cooperate, offer and connect in the fixed plate
The screw buckle of bolt cooperation;
It is provided with detection mouth in the middle part of the closure plate, closeouts is provided in the detection mouth, is provided in closeouts
Detection mouth blocks screw.
Compared with the prior art, the present invention has the following beneficial effects:
The present invention is blocked up using end and attachment device, is placed in sealing material in junction, and the pipe end that will need to block blocks, and improves
Efficiency, while can detecte gas, air pressure real time status in pipeline by the way that the detection mouth that end blocks is arranged in, it is ensured that safety
Construction.

Specific embodiment
As shown in Figure 1, Figure 2, Figure 3 shows, 8, attachment device and detection mouth are blocked up in gas transmission line pipeline pipe end plugging device, including end
9, its main feature is that: the end stifled 8 includes holding stifled inner ring 8-1, holding stifled outer ring 8-2 and closure plate 8-3, and inner ring 8-1 and end are blocked up in the end
Stifled outer ring 8-2 and closure plate 8-3 is affixed, the annular groove 8-4 for accommodating pipe end is formed, in use, being built into annular groove 8-4 close
End stifled 8 is fastened on 7 port of pipeline, the connecting plate 4 by envelope material 2, and one end is by holding stifled fixing bolt 3 and the end stifled outer
8-2 connection is enclosed, the other end is connect by connecting bolt 5 with fixed plate 6, and the fixed plate 6 is fixed on the duct wall, described
The via hole for offering on stifled outer ring 8-2 side wall and stifled fixing bolt 3 being held to cooperate is held, is offered on the connecting plate and fixing bolt
The screw buckles of 3 cooperations and with the via hole that connect cooperation of bolt 5, offer in the fixed plate 6 and the screw thread that connect bolt 5 and cooperate
Button;
It is provided with detection mouth 9 in the middle part of the closure plate 8-3, closeouts is provided in the detection mouth 9, is set in closeouts
It is equipped with detection mouth and blocks screw 1.
Use process:
The present invention in use, improve as follows:
1, when 7 port of gas transmission line pipeline needs to block, by filling sealing material 2 full of in the stifled annular groove 8-4 in end;
2, the end for filling sealing material 2 stifled 8 is placed in 7 port suitable position of pipeline;
3, end stifled 8 is promoted into certain depth;
4, fixed plate 6 is welded in 7 outer wall suitable position of pipeline;
5, appropriateness tightens screw, makes to fill sealing material sold stowing pipe end and hold in stifled annular groove, sufficiently plays
Sealing blocking effect;
6, it will test mouth and block screw 1 and unscrew and remove, connecting detection device detects manifold pressure situation of change, guarantees
Construction safety is convenient.When in pipeline being mixed gas, detectable gas ingredient, monitoring gas component ratio ensures to apply safely
Work.
