Corresponding deformation can be produced so that leak stopping lid 101 covers when sealing, thereon for different pipelines
Coverage rate 101b matches with the pipe shape at leakage hole, reaches perfectly to cover sealing.
Leak stopping cap 103, for through leakage hole, is sent into the inner side of leakage hole by leak stopping bar 102, and can
When leak stopping cap 103 moves towards leakage hole, the port sidewall of leak stopping cap 103 is produced overall outside
Deformation power.
This leak stopping bar 102 is vertically set on the coverage rate 101b of leak stopping lid 101, and is prolonging along it
Stretch and on direction, provide a through hole 102a running through leak stopping bar 102 and leak stopping lid 101.This leak stopping bar 102
Mainly include that rear end near leak stopping section 102b of coverage rate 101b and stretches out along leak stopping section 102b
Mobile section 102c, wherein leak stopping section 102b for leak stopping time assign into leakage mouth in, leakage hole is entered
Row directly preliminary leak stopping, be generally higher than for the length of this leak stopping section 102b bond on leak stopping lid 101 close
The thickness of sealing 101c and pipeline wall thickness sum.
Mobile section 102c on leak stopping bar 102 is for coordinating with leak stopping cap 103, to leak stopping cap 103
Move and guide so that leak stopping cap 103 moves along mobile section 102c.Outside this mobile section 102c

This leak stopping cap 103 is the most cylindrical, and centre has arrangement notch 103d.Outside leak stopping cap 103
Footpath is identical with the external diameter of leak stopping section 102b on leak stopping bar 102, the internal diameter of median slot 103d and leak stopping
The external diameter of the mobile section 102c on bar 102 is identical, is so set in leak stopping bar 102 when leak stopping cap 103
Mobile section 102c on time, the outermost surface 102e(i.e. leak stopping of its lateral surface 103e and leak stopping bar 102
The lateral surface of section 102b) flush, it is simple to leak stopping bar 102 assigns in leakage hole, also avoids external diameter not
Secondary is caused to destroy with to leak stopping mouth.The internal diameter of leak stopping cap 103 median slot 103d is with stifled as required
The external diameter of the mobile section 102c on leakage bar 102 can differ.
In order to ensure that the sidewall 103b of the leak stopping cap 103 arc transiting surface 102d on leak stopping bar 102 drives
Kinetic energy enough deforms upon, and the degree of depth (i.e. disposing the degree of depth of notch 103d) of this leak stopping cap 103 is more than stifled
Leakage bar 102 enters into the length inside leakage hole, it is ensured that leak stopping cap 103 is along mobile section 102c towards letting out
There is when leak moves sufficiently long stroke so that the sidewall 103b of leak stopping cap 103 port can be with
Arc transiting surface 102d contact on leak stopping bar 102, overall product under the effect of arc transiting surface 102d
Dough is to the deformation of inner-walls of duct (i.e. revealing mouth direction), and the part deformed upon can cover whole
Individual leakage hole and peripheral part thereof.
The end face 103f of leak stopping cap 103 port is designed to the arcwall face matched with arc transiting surface 102d,
So when both contact, by both cooperations so that leak stopping cap 103 sidewall is more prone to shape
Become, and reliable and stable, it is to avoid leak stopping cap 103 sidewall 103b ruptures.
Meanwhile, the top 103c of leak stopping cap 103 is designed to a vertebral body structure, is so easy to leakage
Mouthful assign operation.
Owing to needing to produce certain deformation when leak stopping cap 103 works, its entirety can use has a setting
The material of degeneration energy is made.
When the leak stopping nail 100 utilizing such scheme to be formed carries out leak stopping, concrete operating procedure is as follows:
(1) nail rod 104 is located in leak stopping set 105 on through hole 102a in, and nail rod 104 from
To be stretched out from the lateral surface of leak stopping lid 101 by end so that the leak stopping cap 103 of nail rod 104 front end is set in
In leak stopping set 105 on the mobile section 102c of leak stopping bar 102, thus complete the assembling of leak stopping nail.
(2) leak stopping is followed closely entirety and assign in leakage hole 301 so that leak stopping bar 102 is together with being set in
Leak stopping cap 103 thereon together through leakage hole 301, until the leak stopping lid 101 on leak stopping bar 102 with
Pipeline 300 lateral wall contact, it is achieved from outer side covers and seal up leakage hole 301(as shown in Figure 2),
Now leak stopping section 102b of leak stopping bar 102 assigns in leakage hole 301, and its lateral wall will be to leakage hole
The inwall of 301 fully extrudes, and blocks in leakage hole 301.
(3) leak stopping lid 101 is withstood towards leakage hole so that leak stopping lid 101 is pressed by sealing member 101c
The outside of tight pipeline 300, it is to avoid its back side leakage hole moves.
(4) pulling out nail rod 104 from outside, nail rod 104 will drive leak stopping cap 103 along leak stopping bar
Mobile section 102c on 102 moves to leakage hole 301, until the top of mobile section 102c reaches leak stopping
The bottom 103a of cap 103.
(5) Fig. 3 is seen, in moving process, when sidewall 103b and the leak stopping of leak stopping cap 103 port
Arc transiting surface 102d contact on bar 102, overall generation face under the effect of arc transiting surface 102d
The deformation opened to inner-walls of duct (i.e. reveal mouth direction) and will not rupturing；When this deforms upon
After deformation part 103g reaches certain length, it will push down the inner-walls of duct of leakage hole surrounding, thus
Cover whole leakage hole and peripheral part thereof, when pressure reaches to a certain degree, formation is sealed；Process
In, deformation part 103g to the pressure of inner-walls of duct except moved by leak stopping cap 103 generation thrust it
Outward, in pipeline, the pressure of flow media is by producing the pressure towards inner-walls of duct to deformation part 103g, makes
Obtain deformation part 103g and can further seal compression inner-walls of duct, it is to avoid medium is from deformation part
Contact position between 103g and inner-walls of duct flows to leakage hole.
(6) leak stopping hat change part 103g is when sealing inside compression leakage hole, and its pressure will make
Duct wall moves towards the leak stopping lid in outside, and owing to leak stopping lid 101 is withstood, leak stopping lid 101 is by close
Sealing 101c is from outer side covers and seals compression leakage hole.Accordingly, from the outside of leakage hole, leakage hole
In the middle of and leakage hole inside three aspects leakage hole is completed sealing and plugging simultaneously.
Example 2
Seeing Fig. 4, the leak stopping nail 200 that this example provides mainly includes that nail rod 204 and leak stopping overlap 205 liang
Part.The cross section of leak stopping set 205 is "T"-shaped, mainly by leak stopping lid 201 be arranged on leak stopping and cover
Leak stopping bar 202 formed, leak stopping lid 201 covers the outside of leakage hole for compressing and sealing, and makes
Leak stopping bar 202 thereon is through leakage hole.Nail rod 204 is movably worn along leak stopping bar 202 bearing of trend
Being located in leak stopping set, its head arranges guide pad 203, when nail rod moves in leak stopping is overlapped, and guide pad
203 coordinate with the free end 202b of leak stopping bar, and the free end driving leak stopping bar is overall towards inner-walls of duct
(i.e. revealing mouth direction) deformation, and make the deformations interior side compression from leakage hole sealing cover and let out
Leak.
In the specific implementation, the leak stopping lid 201 in leak stopping set 205 covers sealing for compression to the program
The outside of leakage hole, it generally bends body structure, arcwall face 201a as the operating surface of leak stopping lid 201,
For the operation of outer bound pair leak stopping lid 201, such as top pressure etc..Owing to leak stopping lid 201 is positioned at outside leakage hole,
The round and smooth structure of its arc can also be prevented effectively from other structure (such as square, polygon etc.) easily to stifled
The problem of the damage that leakage other parts on-the-spot cause problems such as (scuffing that e.g., corner angle causes) puncturing.
But leak stopping lid 201 is not limited to this structure.
Plane 201b of the leak stopping lid 201 of bow body structure is as the coverage rate 201b of leak stopping lid, in leak stopping
Time for living whole leakage hole and peripheral part thereof from outer side covers.
In order to ensure the sealing effectiveness outside leak stopping lid 201 covering sealing leak mouth, at coverage rate 201b
On be provided with a seal member 201c, realize coverage rate 201b and leakage hole by this seal member 201c
And the sealing between peripheral part connects.
Some fluid sealants or the bonding of other sealant composition specifically can be used for this seal member 201c
Sealant, depending on the material of pipeline and the medium of Qi Nei and pressure medium size, if energy
Enough guarantee seals the effect connected.
In order to reach sealing effectiveness, however it is not limited to using the layer that is bonded and sealed, seal member can use sealing ring
(concrete such as rubber ring) replaces the layer that is bonded and sealed.Under the compression of leak stopping lid 201, can rise equally
To the effect strengthening sealing.
So leak stopping lid 201 of structure typically can use the material with certain deformability to be formed, so
Corresponding deformation can be produced so that leak stopping lid 201 covers when sealing, thereon for different pipelines
Coverage rate 201b matches with the pipe shape at leakage hole, reaches perfectly to cover sealing.
Leak stopping bar 202 is vertically set on the coverage rate 201b of leak stopping lid 201, and is extending along
A through hole 202a running through leak stopping bar 202 and leak stopping lid 201 is provided on direction.This leak stopping bar 202 exists
Being interspersed in leakage hole during leak stopping, and produce deformation under pressure, its free end 202b passes through shape
Change portion covers whole leakage hole and peripheral part thereof in the inner side of leakage hole.
Being embodied as, leak stopping bar 202 can use the metal material with certain deformation nature to make, and makes
Obtain leak stopping bar 202 will not rupture when deformation.
In this example, nail rod 204 matches with the through hole 202a in leak stopping set 205, and entirety can be moved
In the dynamic through hole 202a being located on leak stopping set 205, and length is more than leak stopping bar 202 and leak stopping lid
The total length of 201, arranges guide pad 203 in the front end of nail rod 204 simultaneously.Thus, when nail rod 204
When being located in through hole 202a, the free end of nail rod 204 will stretch out from the lateral surface of leak stopping lid 201,
As long as so pull nail rod 204 from outside, nail rod 204 will drive the guide pad 203 of its front end towards letting out
Leak moves, and guide pad 203 extrudes the free end 202b of leak stopping bar 202, passes through guide effect so that
The free end 202b of leak stopping bar 202 occurs towards inner-walls of duct (i.e. along the spigot surface 203a of guide pad 203
Reveal mouth direction) overall deformation, thus cover whole leakage by deformations in the inner side of leakage hole
Mouth and peripheral part thereof.
The bicone structure that this guide pad 203 specially one bottom surface connects, two in this bicone structure
The shape of cone is the most identical, can be according to actual requirement depending on.The guide pad 203 of this bicone structure
The top of middle upper cone 203c connects with nail rod 204, and its conical surface 203a is as the guiding of guide pad 203
Face 203a, for coordinating the free end 202b of leak stopping bar.Owing to spigot surface 203a is for having a constant inclination
The conical surface of rake angle, when guide pad 203 is towards in leakage hole moving process, the top of spigot surface 203a
Be first into the inside of leak stopping bar free end 202b, and with free end 202b contact internal walls；Along with leading
Continuing to move to block 203, spigot surface 203a will gradually extrude the inside of leak stopping bar free end 202b, right
The inside of free end 202b applies an extruding force being gradually increased towards outside；Along with guide pad 203
Continuing to move to, this extruding force will be gradually increased, and extruding leak stopping bar free end 202b then can be driven overall
Outwards deformation, owing to spigot surface 203a is the conical surface of gradual change, itself and the surrounding energy of free end 202b inwall
Enough contact simultaneously, then the surrounding of free end 202b inwall can be applied squeezing of identical gradual change simultaneously
Pressure so that leak stopping bar free end 202b can overall the most outwards deformation, and will not rupture,
Form ring-type deformations 202c(as shown in Figure 6).
Continuous along with guide pad 203 is moved, and deformations 202c will become larger and gradually towards leakage
Mouth is mobile, until the medial surface of deformations 202c contacts and compresses pipe inner wall.
When guide pad 203 displacement reaches maximum, the deformation of leak stopping bar free end 202b is up to
Maximum, its deformations 202c by leakage hole interior side compression and seal cover whole leakage hole and
Peripheral part.
The concrete angle of this spigot surface 203a can according to the actual requirements depending on, and spigot surface 203a and nail rod
Use arc transition between 204 lateral surface, here and spigot surface 203a and leak stopping bar free end 202b it
Between cooperation.
Lower cone 203d in the guide pad 203 of bicone structure assigns end as what whole leak stopping was followed closely,
And the Breadth Maximum (i.e. the Breadth Maximum of guide pad 203) that lower cone 203d is from the bottom up is slightly larger than
The external diameter of leak stopping bar 202 so that leak stopping bar 202 can directly assign into leakage hole with lower cone 203d
In, and the obstruct that leakage hole is to leak stopping bar 202, so by the conical surface 203b energy on lower cone 203d
Enough very easily leak stopping is followed closely entirety to assign in leakage hole.
Cone is generally for the cone in the guide pad 203 of bicone structure, as required can also
Use other multiaspect cones.
When the leak stopping nail 200 utilizing such scheme to be formed carries out leak stopping, concrete operating procedure is as follows:
(1) nail rod 204 is located in leak stopping set 205 on through hole 202a in, and nail rod 204 from
To be stretched out from the lateral surface of leak stopping lid 201 by end so that the guide pad 103 of nail rod 204 front end and leak stopping
Leak stopping bar 202 corresponding matching in set 205, thus completes the assembling of leak stopping nail.
(2) leak stopping is followed closely entirety and assign in leakage hole 301 so that leak stopping bar 202 is together with nail rod 204
On guide pad 203 together through leakage hole 301, until the leak stopping lid 201 on leak stopping bar 202 and pipe
Road 300 lateral wall contact, it is achieved from outer side covers and seal up leakage hole 301(as shown in Figure 5),
During now leak stopping bar 202 assigns into leakage hole 301, the inwall of leakage hole 301 will be carried out by its lateral wall
Fully extruding, blocks in leakage hole 301.
