Description
Technical field
The invention belongs to pipeline construction equipment technical field, and in particular to a kind of sealing for internal diameter of the pipeline butt end weld seam fills
Put.
Background technology
In the prior art, in order to make full use of the underground space and prevent equipment weathering corrosion, the pipeline of city central heating is all
Provided underground can be embedded to, the space being not only not take up above road, moreover it is possible to prevent pipeline weathering corrosion caused by exposing to the weather, manage
Road also can set multi-protective layer to be used for preventing corrosion of the soil to pipeline, the service life of pipeline before provided underground in outer layer
Obtain certain guarantee.
But over time, pipeline can not only be corroded in underground by soil, pipeline can also be entered from inside
Row corrosion；Pipeline can inject high temperature water body in warm season, by the water temperature of Thermal Corp's water injection end generally at 80 DEG C, and lead in water body
Chemical composition can be often added, is both to be needed to produce also for preventing user's private discharge pipe hot water, high temperature water body and chemistry
Composition will necessarily cause to corrode to inner-walls of duct；And it is anhydrous stopping warm season pipeline inner pumping, pipe temperature reduces, in pipeline
Wall by with water body contact again to and air contact, by high temperature to the change low temperature, rusty stain is fairly obvious, over time
The phenomenon of corrosive pipeline leakage is very universal, and this is also that current most urban road generally existings constantly excavate showing for maintenance pipeline
As, and excavate and safeguard it is that leak is carried out, and the change of leak pressure differential only after leakage could be found, because
This, urban road constantly converts place, and excavate the phenomenon filled up very universal, has a strong impact on trip.
In order to prevent it from internal corrosion hot duct, being inwall one layer of high temperature resistant overcoat of setting in pipeline mostly, so
The inner wall corrosion of pipeline can be substantially reduced, but pipeline itself has regular length, can will be first more with pipeline in laying
Tail alignment carries out butt welding laying, and weld is carried out from outer wall, both easy to operation to be also prevented from connecing inside
The overcoat at place by high temperature failure, can not seal although pipeline is the outside weldings for having thickness to the outer wall of pipeline,
But the phenomenon of heat transfer can more or less impact to inwall, and then the protective layer of internal diameter is damaged；Moreover internal diameter
Joint still can have gap, after a long time use high temperature water body and chemical cost can constantly corrode internal diameter docking seam
At gap, and the space at gap is small, and the residual in warm season gap is water stain to be put aside and continuous corrosion pipeline even in stopping, so as to make
Gradually corrode at internal diameter butt seam into pipeline, ultimately cause pipe leakage, and in the pipeline of whole city central heating,
The quantity of joint is very huge, is currently to have no idea to protect internal diameter of the pipeline commissure；Therefore, Yi Houkai
Road breaking face and the constantly phenomenon of service conduit still can generally existing, trip or can be impacted.
At present, some special equipments are safeguarded to internal diameter of the pipeline, but itself complexity of its equipment is high, and
The diameter of pipeline needs to differ according to heating, and the poor universality of special equipment, common Thermal Corp is difficult to bear to purchase
The expense of professional equipment is bought and safeguards, moreover Thermal Corp is mostly financial subsidies and the industry being had a great influence by fuel market, is adopted
With the complication equipment of specialty come to carry out operation be unpractical, constantly safeguarded with its later stage, not as perfect tightness early stage.
In summary, a kind of special equipment that can be sealed to internal diameter of the pipeline joint weld seam of design, which has seemed, very must

Just；And the diameter of the outermost rotation of adhesive pouring nozzle 8 determines that is, adhesive pouring nozzle 8 is outermost at first after internal diameter of the pipeline is measured
Diameter is the internal diameter certainly less than pipeline, and between gap be exactly follow-up gluing thickness, and adhesive pouring nozzle 8 external diameter change
The operation and adjustment of universal rubber wheel 18 are not interfered with；Universal rubber wheel 18 and adhesive pouring nozzle 8 can push after adjusting to pipeline inside.
Secondly band can, be passed through in the end of pipeline, the change of size and data by fastening pawl 20 and fixing fixing device
The telescopic boom III 23 for having graduated scale is controlled, and most the axis of bearing block 3 and the axis of pipeline are corresponding at last, and support set
Pipe 12 in bearing block 3 as being slidably connected.
3rd, running gear and fixing device be ready for it is ready after, progressively running gear is elapsed forward, works as universal rubber wheel
18 when touching the weld seam of pipeline docking, has obvious bumps and jolts part, operating personnel can perceive by steering wheel 2；
Now, supporting sleeve 12 reversely being pulled out into a certain distance, this distance is exactly the distance between adhesive pouring nozzle 8 and universal rubber wheel 18,
The weld seam for the alignment pipeline of adhesive pouring nozzle 8 for being, opens gluing pumping plant 1 and is delivered to fluid sealant at adhesive pouring nozzle 8 by flexible pipe, operating personnel
And uniform rotation steering wheel 2, it is ensured that the speed and glue amount of gluing are uniform；The quantity that the yardstick of rotation is set according to adhesive pouring nozzle 8 come
It is determined that as adhesive pouring nozzle 8 set 3 when, rotational angle be 120 degree, adhesive pouring nozzle 8 set 4 when, rotational angle be 90 degree, successively
Analogize；After the completion of gluing, continue reversely to retract supporting sleeve 12 and dismantle fixing device that the sealing work of weld seam successively can be completed
Industry.
