Background technique
Currently, in pipeline transportation, it may appear that the pipeline cracking situation of burst, so that pipeline cracks in link position
Leakage, it is therefore desirable to interim connection reparation is carried out, since when pipeline connects, connector is mostly to customize part, and installation process is multiple
It is miscellaneous, especially when caliber size changes, reducing connecting tube is mostly used to carry out installation connection, therefore the two of reducing connecting tube
End pipe diameter is identical with the caliber to connecting tube respectively, and mostly pre-production is good, cannot carry out in time under bursty state interim
Connection, influence the transmission of pipeline, existing interim reparation is all to carry out repair using tube body spare part, by connecting pipe into
The further connection of row, avoids leaking, but operation technique is complicated, inefficiency.
Publication number CN206191121U discloses one kind to, drainpipe variable diameter attachment device, and the variable diameter attachment device connects
It is connected between water inlet pipe and tapered pipeline, including entirety variable diameter connector funnel-shaped, variable diameter connector both ends
Hierarchic structure is all offered on inner wall, the ladder width opened up on variable diameter connector connection water inlet pipe one end inner wall is equal into water
The thickness of pipeline, water inlet pipe water outlet protrude into variable diameter connector, offer anti-slip layer on water inlet pipe water outlet lateral wall
One, sealing ring one is provided between water inlet pipe water outlet lateral wall and variable diameter connector, the water outlet end face of water inlet pipe is supported
It is against on the cascaded surface, which is attached using reducer pipe, and the both ends size of the variable diameter is according to connecting tube
Caliber is designed production, when wherein one when connecting tube occurs damaged, can not further be attached, the variable diameter of connection
Size is fixed.
Summary of the invention
In order to improve above situation, a kind of pipeline transportation large scale reducer pipe of the utility model temporarily connects sealing device and mentions
It has supplied one kind to carry out environmental sealing to auxiliary pipeline by pressure bladder inflation, has made to be formed between auxiliary pipeline and main pipeline interim
The sealing device of connection.It is applicable in the connection sealing of different size variable diameters.
A kind of pipeline transportation large scale reducer pipe of the utility model temporarily connect sealing device be achieved in that it is practical
A kind of novel pipeline transportation large scale reducer pipe temporarily connects sealing device by connecting sleeve, the connection edge of a wing, check valve, interior sealing
Air bag, air injection opening, connection clamp arm and flexible rubber ring composition, the connection clamp arm are ring structure, and connecting sleeve is placed on connection
In clamp arm, described connecting sleeve one end is to horizontal direction bending, and in connection clamp arm, and the connection edge of a wing is embedded at connection folder
On arm, and it is connected with connecting sleeve one end, connection edge of a wing thickness is gradually increased from outer ring to inner ring, and interior pressure bladder is set
In connection clamp arm inner ring, the interior pressure bladder is ring structure, passes through flexible rubber ring and connection on the outside of the interior pressure bladder
Clamp arm is connected, and the air injection opening is placed on interior pressure bladder, and be connected inside interior pressure bladder, built in the air injection opening
There is check valve, and flow direction is that mounting hole, the mounting hole are provided on the interior pressure bladder in ecto-entad pressure bladder
Be built-in with check valve, and flow direction be by interior pressure bladder from inside to outside, be equipped with friction on ring outer wall in the interior pressure bladder
Pad.
In use, connecting sleeve is placed on main pipeline first when carrying out interim reparation connection to pipeline reducing diameter position
Then inner groovy is opened on auxiliary conduit connection end outer wall, then auxiliary conduit connection end is protruded into from interior pressure bladder inner ring in connecting pin
In main pipeline, then by being inflated in the inside pressure bladder of air injection opening, gas enters interior pressure bladder by air injection opening
Interior, interior pressure bladder gradually expands, and interior pressure bladder inner ring expansion squeezes auxiliary pipeline, and interior pressure bladder inner ring is gradually placed in
In inner groovy on auxiliary pipeline outer wall, and then interior pressure bladder carries out environmental sealing to auxiliary pipeline and fixes, so to auxiliary pipeline and
Main pipeline is temporarily connected, and main pipeline connecting pin oral area is connected cutting ferrule and connects the structure of clamp arm, the formation of interior pressure bladder
Sealing, when dismantling to main pipeline and auxiliary pipeline, the check valve opened in mounting hole is deflated, and is reached and is passed through sealing
Air bag inflation carries out environmental sealing to auxiliary pipeline, makes to form the purpose temporarily connected between auxiliary pipeline and main pipeline.
Beneficial effect.
One, it quickly can temporarily be connected.
Two, it can be avoided and cause to connect mismatch problem to the replacement of connecting tube.
Three, it is applicable in the connection sealing of different size variable diameters.
Detailed description of the invention
