Specific embodiment
It should be noted that in the case where there is no conflict, in the embodiment and each embodiment in the utility model
Feature can be mutually combined.
The utility model is described in detail below with reference to the accompanying drawings and with reference to embodiment.
Fig. 1~5 schematically show a kind of internal-expansion type plugging mechanism of embodiment according to the present utility model.This is interior
Expanding plugging mechanism includes block head 1, the stent 2 for supporting block head and the cylinder 3 that power is provided for block head 1.
Block head 1 is supported by stent 2.Cylinder 3 is fixedly connected on stent 2, and power is provided for block head 1.
Block head 1 includes stop part 11, compression first 12 and closeouts 13.Stop part 11 is the component of tubular, with branch
Frame 2 is fixedly connected.Compression first 12 is generally T-shaped.The first end of compression first 12 is sheathed in the stop part 11 of tubular, and can
It is slided with respect to stop part 11, while the first end of compression first 12 is connected with the piston rod of cylinder 3, the movement for compression first 12 provides
Power.The second end of compression first 12 has flange.Closeouts 13 are annular, are sheathed on outside the first end of compression first 12, and are located at
Between the flange of second end of compression first 12 and stop part 11.In this way, compression first 12 and stop part 11 are located at closeouts 13 respectively
Both ends.When compression first 12 bounces back with the piston rod of cylinder, the flange extrusion closeouts 13 of first 12 second end are compressed, will be blocked
Part 13 presses to stop part 11, and stop part 11 and first 12 cooperation of compression make 13 compressive deformation of closeouts, and middle part expansion protrusion is close to pipe
The inner wall on road, so as to fulfill in channel interior to plugging pipelines.In such manner, it is possible to end face closure is avoided to cause pipeline to pipeline extruding
Deformation even damage is scrapped.Plugging block is polyurethane sealing sprue in the present embodiment, which is easy to compressive deformation
And fitted closely with the inner wall of pipeline, plugging effect is good.
Compression first 12 in axially penetrated through air flue, away from closeouts one end gas port at be equipped with inflatable interface 5, for
It ventilates after the completion of closure to pipeline, carries out leak test.
The internal-expansion type plugging mechanism of the utility model further includes the relocation mechanism 4 that can adjust 1 position of block head, floating engine
Structure 4 is mounted on stent 2.
Relocation mechanism 4 includes bottom plate 41, installing plate 42, the rotatable X being installed on bottom plate 41 to relocation mechanism 43, with
And rotatably it is installed on Y-direction relocation mechanisms 44 of the X on relocation mechanism 43.Installing plate 42 is mounted on Y-direction relocation mechanism 44,
Stent 2 is connected with installing plate 42.Stent 2 is fixed on installing plate 42 in the present embodiment.X to relocation mechanism 43 include X to turn
Axis and with X to the X that shaft is fixedly connected to revolving part, X is mounted on by both ends bearing on bottom plate 41 to shaft.Y-direction floating engine
Structure 44 includes Y-direction shaft and the Y-direction revolving part being rotatably connected with it, Y-direction shaft are fixedly connected on X on revolving part.X to turn
The direction of axis and Y-direction shaft is mutually perpendicular to, and adjusts installing plate 42 respectively in the plane stretched out with block head 1 and retraction direction is vertical
On position, so as to adjust the position of block head 1 in pipeline in the radial direction.When nozzle position has deviation, prevent by
Pipeline one side is extruded when the other strength of pipeline causes closure, and opposite side also leaves the problem of gap closure is not in place；Imitate closure
Fruit is influenced to substantially reduce by the position of nozzle and Size Error, improves the precision of leak test；Meanwhile it can also reduce adding for pipeline
The production cost of enterprise is saved in work and matching requirements.
The internal-expansion type plugging mechanism of the utility model is additionally provided with multiple micro-adjusting mechanisms, and micro-adjusting mechanism includes fine tuning block 45,
Bottom plate 41 and X are between relocation mechanism 43 and installing plate 42 and X are equipped with fine tuning block 45 between relocation mechanism 43., only
Block 47 is resisted against the spring 46 between fine tuning block 45 and stop block 47, by adjusting the depth of fine tuning block 45, to adjust
The power being applied on stop block 47 of spring 46 is compressed, the amount of floating of bottom plate 41 and installing plate 42 is limited by stop block 47, from
And achieve the purpose that the amount of floating for adjusting relocation mechanism.
Water pipe, oil pipe are generally metal plate/stamping parts, and opening part is rigidly poor, the internal-expansion type stopple plugging machine of the utility model
The block head 1 of structure gos deep into water pipe, in oil pipe, avoids the closure mode that nozzle is withstood using cylinder or oil cylinder, will not cause
The problem of pipeline deforms and causes product rejection.Meanwhile when nozzle position has deviation, prevent due to the closure of pipeline other strength less than
The problem of position；Plugging effect is made to be influenced to substantially reduce by the position of nozzle and Size Error, improves the precision of leak test；It reduces
The production cost of enterprise is saved in the processing and matching requirements of pipeline.
In use, stent 2 is installed on the installing plate 42 of relocation mechanism 4 first, makes whole device whole to extension, make
Block head 1 stretches into the suitable position in the water pipe or oil pipe for the treatment of leak test.Then, cylinder 3 is made to ventilate, pulls 1 receding of block head,
Polyurethane sealing sprue deforms after being squeezed, central raised and be close to the inner wall for treating leak test pipeline, and relocation mechanism 4 is with according to treating leak test pipe
The position radial floating adjustment position on road, the closure inside water pipe, oil pipe.Last pipeline ventilation, carries out pipeline leak test.Leak test is complete
It dies after, cylinder 3 is tossed about ventilation, and block head 1 is made to return to original position, and polyurethane sealing sprue replys original shape.Finally, make interior swollen
Formula plugging mechanism integrally exits pipeline, completes leak test.
The foregoing is merely the better embodiments of the utility model, are not intended to limit the utility model, it is all
Within the spirit and principles of the utility model, it is new to should be included in this practicality for any modifications, equivalent replacements and improvements are made
Within the protection domain of type.
