Wedge-shaped pushing block 5 connects, and the other end is connected with packing element extrusion ring 7, when telescopic device stretches out, promotes wedge-shaped pushing block 5 to slide, and push away
Dynamic packing element extrusion ring 7 slides so that anchoring device proceeds by grappling, and sealing device starts to seal.Specifically, the telescopic device
For driving hydraulic cylinder 6, and the telescopic rod of driving hydraulic cylinder 6 is connected with wedge-shaped pushing block 5, and cylinder body is connected with packing element extrusion ring 7.
In order to facilitate the said structure for understanding plugging device, the following detailed description of its operation principle.
When pipeline failure needs carry out maintenance or change pipe, served a ball cylinder by wiper in faulty section upstream
Plugging device in two pipes is launched, plugging device moves under the promotion of tube fluid to trouble point.During movement, it is installed on
The support lacquer disk(-sc) 2 at plugging device body both ends plays the role of support, ensures that the Runtime Infrastructure of plugging device entirety is put down with conduit axis
OK, and support the presence of lacquer disk(-sc) 2 to play a protective role to cartridge 8 and grappling slips 4, prevent it from scratching and grinding
Damage.
Another feature of plugging device is that have the function of pigging in this pipe.Pigging lacquer disk(-sc) is installed at the both ends of plugging device, clearly
The outside diameter of pipe lacquer disk(-sc) is slightly larger than internal diameter of the pipeline, and plugging device is in pipe in operational process, pigging lacquer disk(-sc) and inner-walls of duct interference all the time
Contact, pigging lacquer disk(-sc) will clear up the impurity of inner-walls of duct, keep inner-walls of duct clean, ensure grappling and closure process peace
It is complete reliable.
Plugging device is communicated by ultralow frequency pulse signal and the outer remote control equipment of pipe in pipe during movement.In pipe
Plugging device is constantly sent out ultralow frequency pulse signal, and manages outer remote control equipment and plugging device is positioned by this signal,
When plugging device is close to failure pipeline section, manage outer remote control equipment to plugging device transmission reduce-speed sign, plugging device receive this signal into
Row deceleration is simultaneously parked in designated position respectively.
After remote control equipment detects that plugging device has pulled up precalculated position in pipe outside pipe, pass through ultralow frequency pulse signal
Send grappling to it to instruct, after plugging device receives grappling instruction in pipe, driving hydraulic cylinder 6 is started to work, and piston is in hydraulic oil
Under the action of drive piston rod it is protruding, piston rod by earrings with wedge shape pushing block 5 be connected, wedge-shaped pushing block 5 is in piston rod
Moved axially under promotion along main body 1, due between grappling slips 4 and wedge-shaped pushing block 5 there are certain key groove, so wedge shape pushes away
The axial movement of block 5 will drive grappling slips 4 that radial dilatation occurs, until grappling slips 4 is contacted with inner-walls of duct.Pass through control
The hydraulic pressure of driving hydraulic cylinder 6, makes to form enough anchorage forces between grappling slips 4 and inner-walls of duct, ensures grappling effect
Securely and reliably.
Driving hydraulic cylinder 6 in pipe on plugging device belongs to floating connection, and the both ends of driving hydraulic cylinder 6 are the sides by earrings
Formula connects wedge-shaped pushing block 5 and packing element extrusion ring 7 respectively.When driving hydraulic cylinder 6 works, cylinder body is protruding with piston rod, together
When drive wedge-shaped pushing block 5 to produce axial movement with packing element extrusion ring 7, the axial movement of wedge-shaped pushing block 5 causes grappling slips 4 to occur
Radial dilatation, and the axial movement of packing element extrusion ring 7 is by continuous crush seal packing element 8.But since grappling slips 4 has just started radially
Do not contacted during expansion with inner-walls of duct also, and the deformation of cartridge 8 then needs certain extruding force, so grappling card at this time
Watts 4 outward radials first stretch out, and crimp will not occur for cartridge 8.When grappling slips 4 starts to contact with inner-walls of duct
Afterwards, with the increase of anchorage force, the power of crush seal packing element 8 is also increasing, so driving hydraulic cylinder 6 will extrude at the same time at this time
Grappling slips 4 and cartridge 8.
Gradually increase with the extruding force of cartridge 8,8 axial shrinkage of cartridge, footpath convex, gradually with pipeline
Wall contacts, and then forms certain specific contact pressure, forms high pressure sealing in pipe.
By calculating, the extruding force that when grappling 4 grappling of slips needs is more than the extruding force needed when cartridge 8 seals,
But since driving hydraulic cylinder 6 is to act on grappling slips 4 and cartridge 8 at the same time with identical power, so driving hydraulic cylinder 6 carries
The driving force of confession will at least meet required power during grappling 4 grappling of slips.To avoid extruding force is excessive from causing cartridge 8 to send out
Raw extruding is destroyed and failed, it is necessary to be any limitation as to the axial stroke of the packing element extrusion ring 7 of crush seal packing element 8, guarantee sealing
The reliability of packing element 8.
After grappling and sealing function, plugging device is sent out end of job signal, manages outer remote control equipment and receives
This signal, then sends to plugging device and tests envelope signal.Then plugging device by packing element shading ring 9 to the annular between two panels packing element
Space fills highly pressurised liquid, the pressure after pressurize for a period of time in monitoring annular space, if there is not pressure drop, then explanation sealing
Function success.
After pipeline both ends successfully block, it is possible to it is middle the problem of pipeline change some row such as pipe, maintenance and grasp
Make, these are repaiied pipe operation and there may come a time when to need the time of even several days one day, and this requires plugging device has high press seal for a long time
Stifled ability.
Unseal and recycle, it is necessary to manage interior plugging device after the pipe end of job is repaiied in all centres.Outer remote control equipment is managed at this time
The collection of letters number is sent back to plugging device, after plugging device receives signal, 6 reverse operation of driving hydraulic cylinder, piston driving piston rod
Shrink, and then pull packing element extrusion ring 7 to be moved backward vertically with wedge-shaped pushing block 5 so that cartridge 8 and 4 footpath of grappling slips
To original state is contracted to, deblocking and solution grappling function are completed.
After deblocking is completed with solution grappling function, plugging device downstream moves under the drive of tube fluid, and from downstream
Wiper ball collecting chamber recycling.High-voltage intelligent closure process is completed in whole pipe.
Obviously, various changes and modifications can be made to the invention without departing from essence of the invention by those skilled in the art
God and scope.In this way, if these modifications and changes of the present invention belongs to the scope of the claims in the present invention and its equivalent technologies
Within, then the present invention is also intended to comprising including these modification and variations.
