Embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
Example 1
Referring to Fig. 1, leak stopping that this example provides nail 100 mainly comprises that nail bar 104 and leak stopping overlap 105 two-part.The cross section of leak stopping cover 105 is "T"-shaped, leak stopping lid 101 and the leak stopping bar 102 that is arranged on leak stopping lid 101, consists of, and leak stopping lid 101 is for compressing and seal the outside that covers leakage hole, and makes the leak stopping bar 102 on it pass leakage hole; And nail bar 104 movably is located in leak stopping cover 105 along leak stopping bar bearing of trend, its front end sleeve is provided with leak stopping cap 103, when the nail bar moves in the leak stopping cover, leak stopping cap 103 coordinates with the leak stopping bar in the leak stopping cover, the port sidewall blocking of leak stopping cap is leaked bar and is driven integral face to inner-walls of duct (revealing a mouthful direction) deformation, and this deformation sidewall covers leakage hole from interior side compression the sealing of leakage hole.
In the specific implementation, the leak stopping lid 101 in leak stopping cover 105 is for covering the outside of seal leakage mouth for this scheme, and it is whole is the bow body structure, and arc shaped surface 101a, as the fore side of leak stopping lid 101, for the operation of outer bound pair leak stopping lid 101, as presses pressure etc.Leak stopping lid 101 is positioned at the leakage hole outside, the problem of the damage that the round and smooth structure of its arc can also effectively avoid other structure (as square, polygonal etc.) easily on-the-spot other parts of leak stopping to be caused (as, the scuffing caused by corner angle, the problem such as puncture).
The plane 101b of the leak stopping lid 101 of bow body structure, as the coverage rate 101b of leak stopping lid, is used for living whole leakage hole and peripheral part thereof from outer side covers when leak stopping.
In order to guarantee that leak stopping lid 101 covers and the sealing effect in the seal leakage mouth outside, be provided with a sealed member 101c on coverage rate 101b, realize that by sealing parts 101c the sealing between coverage rate 101b and leakage hole and peripheral part thereof joins.
In order to reach sealing effect, sealed member 101c is not limited to adopt layer 101c that be bonded and sealed, and a layer 101c replaces being bonded and sealed can to adopt seal ring (concrete as rubber ring).Under the compression of leak stopping lid 101, can play equally the effect of enhanced leaktightness.
So the leak stopping of structure lid 101 generally can adopt the material with certain deformability to form, can produce for different pipelines corresponding deformation like this, while making leak stopping lid 101 cover sealing, coverage rate 101b on it matches with the pipe shape at leakage hole place, reaches perfect covering sealing.
Leak stopping bar 102, for through leakage hole, is sent into leak stopping cap 103 inboard of leakage hole, and can be when leak stopping cap 103 moves towards leakage hole, to the whole outside deformation power of port sidewall generation of leak stopping cap 103.
It is upper that this leak stopping bar 102 is vertically set on the coverage rate 101b of leak stopping lid 101, and along providing a through hole 102a who runs through leak stopping bar 102 and leak stopping lid 101 on its bearing of trend.This leak stopping bar 102 mainly comprises that rear end is near the leak stopping section 102b of coverage rate 101b and along the outward extending mobile section 102c of leak stopping section 102b, wherein leak stopping section 102b assigns into while being used for leak stopping and reveals mouth, leakage hole is carried out to directly preliminary leak stopping, and the length of the 102b of leak stopping section for this reason generally is greater than on leak stopping lid 101 thickness and the pipeline wall thickness sum of layer 101c that be bonded and sealed.
In order to reach stable deformation effect, transition structure 102d on leak stopping bar 102 between mobile section 102c and leak stopping section 102b is an arc transiting surface, by the round and smooth progressive formation of arc transiting surface, both guaranteed the reliability of leak stopping cap 103 sidewall deformation, again convenient operation.
In this example, the through hole 102a in nail bar 104 and leak stopping cover 105 matches, and being located in the through hole 102a on leak stopping cover 105 of Integral movable, and length is greater than leak stopping bar 102 and covers 101 total length with leak stopping.The front end of nail bar 104 is arranged on leak stopping cap 103 neutral position of settling notch 103d bottom 103a, realizes thus driving leak stopping cap 103 to move along the mobile section 102c on leak stopping bar 102.When nail bar 104 is located in through hole 102a, the free end of nail bar 104 will cover 101 outer side surface from leak stopping and stretch out, as long as pull like this nail bar 104 from the outside, the leak stopping cap 103 that nail bar 104 will drive its front end moves towards leakage hole, and the upper also mobile section 102c of mobile section 102c that makes leak stopping cap 103 be set in leak stopping bar 102 moves.
Leak stopping cap 103 is set on the free end of nail bar 104, and it covers whole leakage hole and peripheral part thereof by deformation in the inboard of leakage hole.
These leak stopping cap 103 integral body are cylindrical, and centre has the notch of arrangement 103d.The external diameter of leak stopping cap 103 is identical with the external diameter of leak stopping section 102b on leak stopping bar 102, the internal diameter of median slot 103d is identical with the external diameter of mobile section 102c on leak stopping bar 102, be set in the mobile section 102c of leak stopping bar 102 when upper when leak stopping cap 103 like this, its outer side surface 103e is the outer side surface of leak stopping section 102b with the outermost surface 102e(of leak stopping bar 102) flush, be convenient to leak stopping bar 102 and assign in leakage hole, also avoid the external diameter difference to cause secondary to destroy to the leak stopping mouth.The internal diameter of leak stopping cap 103 median slot 103d can be not identical with the external diameter of mobile section 102c on leak stopping bar 102 as required.
For the arc transiting surface 102d of sidewall 103b on leak stopping bar 102 that guarantees leak stopping cap 103 drives, deformation can occur, the degree of depth of this leak stopping cap 103 (settling the degree of depth of notch 103d) is greater than the length that leak stopping bar 102 enters into the leakage hole inboard, guarantee that leak stopping cap 103 has sufficiently long stroke when leakage hole moves along mobile section 102c, make the sidewall 103b of leak stopping cap 103 ports to contact with the arc transiting surface 102d on leak stopping bar 102, the whole generation towards the deformation of inner-walls of duct (revealing a mouthful direction) under the effect of arc transiting surface 102d, and the part that deformation occurs can cover whole leakage hole and peripheral part thereof.
The end face 103f of leak stopping cap 103 ports is designed to the arc shaped surface matched with arc transiting surface 102d, when both contact, by both cooperations, make leak stopping cap 103 sidewalls be more prone to occur deformation like this, and reliable and stable, avoid the fracture of leak stopping cap 103 sidewall 103b.
Simultaneously, the top 103c of leak stopping cap 103 is designed to a vertebral body structure, is convenient to like this operation of assigning to leakage hole.
Need to produce certain deformation during due to 103 work of leak stopping cap, its integral body can adopt the material with certain deformation nature to make.
When the leak stopping nail 100 that utilizes such scheme to form carries out leak stopping, concrete operating procedure is as follows:
(1) will follow closely bar 104 is located in the through hole 102a on leak stopping cover 105, and the free end of nail bar 104 will cover 101 outer side surface from leak stopping and stretch out, make the leak stopping cap 103 of nail bar 104 front ends be set on the mobile section 102c of leak stopping bar 102 in leak stopping cover 105, complete thus the assembling of leak stopping nail.
(2) leak stopping being followed closely to integral body assigns in leakage hole 301, make leak stopping bar 102 pass leakage hole 301 together with sheathed leak stopping cap 103 thereon, until the lid of the leak stopping on leak stopping bar 102 101 contacts with the outer side wall of pipeline 300, realization is from outer side covers and seal up leakage hole 301(as shown in Figure 2), now the leak stopping section 102b of leak stopping bar 102 assigns in leakage hole 301, its outer side wall will fully push the inwall of leakage hole 301, in leakage hole 301, blocks.
(3) withstand leak stopping lid 101 towards leakage hole, the outside that makes leak stopping lid 101 compress pipeline 300 by Sealing 101c, avoid its back side leakage hole to move.
(4) pull out nail bar 104 from the outside, nail bar 104 will drive leak stopping cap 103 and move to leakage hole 301 along the mobile section 102c on leak stopping bar 102, until the top of mobile section 102c reaches the bottom 103a of leak stopping cap 103.
(5) referring to Fig. 3, in moving process, when the sidewall 103b of leak stopping cap 103 ports contacts with the arc transiting surface 102d on leak stopping bar 102, wholely under the effect of arc transiting surface 102d produce the deformation of opening towards inner-walls of duct (revealing a mouthful direction) and can fracture; After the deformation part 103g of this generation deformation reaches certain length, the inner-walls of duct of leakage hole surrounding be will push down, thereby whole leakage hole and peripheral part thereof covered, when acquiring a certain degree, pressure will form sealing; In process, deformation part 103g to the pressure of inner-walls of duct except being moved by leak stopping cap 103 thrust of generation, in pipeline, the pressure of flowing medium will produce the pressure towards inner-walls of duct to deformation part 103g, make deformation part 103g can further seal the compression inner-walls of duct, avoid medium to flow to leakage hole from the contacting point between deformation part 103g and inner-walls of duct.
(6) the leak stopping hat becomes part 103g when sealing compresses the leakage hole inboard, and its pressure will make tube wall mobile towards the leak stopping lid in the outside, and because leak stopping lid 101 is withstood, leak stopping lid 101 passes through Sealing 101c and compresses leakage hole from outer side covers sealing.Accordingly, in the middle of the outside of leakage hole, leakage hole and the inboard three aspects: of leakage hole leakage hole is completed to sealing and plugging simultaneously.
Example 2
Referring to Fig. 4, leak stopping that this example provides nail 200 mainly comprises that nail bar 204 and leak stopping overlap 205 two-part.The cross section of leak stopping cover 205 is "T"-shaped, and mainly by leak stopping lid 201 be arranged on the leak stopping bar 202 that leak stopping covers and form, leak stopping lid 201 is for compressing and seal the outside that covers leakage hole, and makes the leak stopping bar 202 on it pass leakage hole.Nail bar 204 movably is located in the leak stopping cover along leak stopping bar 202 bearing of trends, its head arranges guide pad 203, when the nail bar moves in the leak stopping cover, guide pad 203 coordinates with the free end 202b of leak stopping bar, drive the free end integral face of leak stopping bar to inner-walls of duct (revealing a mouthful direction) deformation, and make deformations cover leakage hole from the interior side compression of leakage hole sealing.
In the specific implementation, the leak stopping lid 201 in leak stopping cover 205 covers the outside of seal leakage mouth to this scheme for compression, and its integral body is the bow body structure, and arc shaped surface 201a is as the fore side of leak stopping lid 201, for the operation of outer bound pair leak stopping lid 201, as pushed up pressure etc.Because leak stopping lid 201 is positioned at the leakage hole outside, the problem of the damage that the round and smooth structure of its arc can also effectively avoid other structure (as square, polygonal etc.) easily on-the-spot other parts of leak stopping to be caused (as, the scuffing caused by corner angle, the problem such as puncture).But leak stopping lid 201 is not limited to this structure.
The plane 201b of the leak stopping lid 201 of bow body structure, as the coverage rate 201b of leak stopping lid, is used for living whole leakage hole and peripheral part thereof from outer side covers when leak stopping.
In order to guarantee that leak stopping lid 201 covers and the sealing effect in the seal leakage mouth outside, be provided with a sealed member 201c on coverage rate 201b, realize that by sealing parts 201c the sealing between coverage rate 201b and leakage hole and peripheral part thereof joins.
The layer that is bonded and sealed that for sealing parts 201c, specifically can adopt some sealers or other sealing compound to form, specifically determine according to the material of pipeline and medium and the pressure medium size of Qi Nei, as long as can guarantee the effect that sealing is joined.
In order to reach sealing effect, be not limited to adopt the layer that is bonded and sealed, sealed member can adopt seal ring (concrete as rubber ring) to replace the layer that is bonded and sealed.Under the compression of leak stopping lid 201, can play equally the effect of enhanced leaktightness.
So the leak stopping of structure lid 201 generally can adopt the material with certain deformability to form, can produce for different pipelines corresponding deformation like this, while making leak stopping lid 201 cover sealing, coverage rate 201b on it matches with the pipe shape at leakage hole place, reaches perfect covering sealing.
It is upper that leak stopping bar 202 is vertically set on the coverage rate 201b of leak stopping lid 201, and along providing a through hole 202a who runs through leak stopping bar 202 and leak stopping lid 201 on its bearing of trend.This leak stopping bar 202 interts in leakage hole when leak stopping, and produces deformation under pressure, and its free end 202b covers whole leakage hole and peripheral part thereof by deformations in the inboard of leakage hole.
In concrete enforcement, leak stopping bar 202 can adopt the metal material with certain deformation nature to make, and makes the leak stopping bar 202 can fracture when deformation.
In this example, nail bar 204 matches with the through hole 202a in leak stopping cover 205, and being located in the through hole 202a on leak stopping cover 205 of Integral movable, and length is greater than the total length of leak stopping bar 202 and leak stopping lid 201, and the front end at nail bar 204 arranges guide pad 203 simultaneously.Thus, when nail bar 204 is located in through hole 202a, the free end of nail bar 204 will cover 201 outer side surface from leak stopping and stretch out, as long as pull like this nail bar 204 from the outside, the guide pad 203 that nail bar 204 will drive its front end moves towards leakage hole, the free end 202b of guide pad 203 extruding leak stopping bars 202, by leading role, the whole deformation of the free end 202b that makes leak stopping bar 202 along the guide surface 203a generating plane of guide pad 203 to inner-walls of duct (revealing a mouthful direction), thereby cover whole leakage hole and peripheral part thereof by deformations in the inboard of leakage hole.
This guide pad 203 is specially the bicone structure that a bottom surface joins, and the shape of two cones in this bicone structure is not necessarily identical, can determine according to actual requirement.In the guide pad 203 of this bicone structure, the top of upper cone 203c joins with nail bar 204, and its conical surface 203a, as the guide surface 203a of guide pad 203, coordinates for the free end 202b to the leak stopping bar.Because guide surface 203a is the conical surface with certain angle of inclination, when guide pad 203, in the leakage hole moving process, at first the top of guide surface 203a enters into the inside of leak stopping bar free end 202b, and contacts with free end 202b inwall; Along with guide pad 203 continues mobilely, guide surface 203a will push the inside of leak stopping bar free end 202b gradually, and the inside of free end 202b is applied to an extruding force increased gradually towards the outside; Along with guide pad 203 continues mobile, this extruding force will increase gradually, then can drive the whole outwards deformation of extruding leak stopping bar free end 202b, due to the guide surface 203a conical surface that is gradual change, its surrounding with free end 202b inwall can contact simultaneously, then can apply to the surrounding of free end 202b inwall the extruding force of identical gradual change simultaneously, thereby make the leak stopping bar free end 202b can whole outwards deformation simultaneously, and can not rupture, form the deformations 202c(of a ring-type as shown in Figure 6).
Along with the continuous movement of guide pad 203, deformations 202c will become greatly and gradually and move towards leakage hole gradually, until the inner side surface of deformations 202c contacts and compress pipe inner wall.
When guide pad 203 displacement distances reach maximum, it is maximum that the deformation of leak stopping bar free end 202b will reach, and its deformations 202c will cover whole leakage hole and peripheral part thereof in interior side compression the sealing of leakage hole.
The concrete angle of this guide surface 203a can be determined according to the actual requirements, and adopts arc transition between guide surface 203a and nail bar 204 outer side surfaces, here with guide surface 203a and leak stopping bar free end 202b between coordinate.
Be generally cone for the cone in the guide pad 203 of bicone structure, also can adopt as required other multiaspect cones.
When the leak stopping nail 200 that utilizes such scheme to form carries out leak stopping, concrete operating procedure is as follows:
(1) will follow closely bar 204 is located in the through hole 202a on leak stopping cover 205, and the free end of nail bar 204 will cover 201 outer side surface from leak stopping and stretch out, make the guide pad 103 of nail bar 204 front ends overlap leak stopping bar 202 corresponding matching in 205 with leak stopping, complete thus the assembling of leak stopping nail.
(2) leak stopping being followed closely to integral body assigns in leakage hole 301, make leak stopping bar 202 pass leakage hole 301 together with the guide pad 203 on nail bar 204, until the lid of the leak stopping on leak stopping bar 202 201 contacts with the outer side wall of pipeline 300, realization is from outer side covers and seal up leakage hole 301(as shown in Figure 5), now leak stopping bar 202 assigns in leakage hole 301, its outer side wall will fully push the inwall of leakage hole 301, in leakage hole 301, blocks.
(3) withstand leak stopping lid 201 towards leakage hole, the outside that makes leak stopping lid 201 compress pipeline 300 by Sealing 201c, avoid its back side leakage hole to move.
(4) pull out nail bar 204 from the outside, nail bar 204 will drive guide pad 203 and move towards leakage hole 301.
(5) referring to Fig. 6, in moving process, when the guide surface 203a of guide pad 203 contacts cooperation with the free end 202b of leak stopping bar, to apply the extruding force towards leakage hole to the free end 202b of leak stopping bar, under the leading role of guide surface, produce the deformation of opening towards inner-walls of duct (revealing a mouthful direction) and can fracture by the free end 202b that makes the leak stopping bar is whole; After the deformation part 202c of this generation deformation reaches certain length, the inner-walls of duct of leakage hole surrounding be will push down, thereby whole leakage hole and peripheral part thereof covered, when acquiring a certain degree, pressure will form sealing; In this process, deformation part 202c to the pressure of inner-walls of duct except deformation power, in pipeline, the pressure of flowing medium will produce the pressure towards inner-walls of duct to deformation part 202c, make deformation part 202c can further seal the compression inner-walls of duct, avoid medium to flow to leakage hole from the contacting point between deformation part 202c and inner-walls of duct.
(6) the leak stopping hat becomes part 202c when sealing compresses the leakage hole inboard, its pressure will make tube wall move towards the leak stopping lid 201 in the outside, due to leak stopping lid 201, by top, leak stopping lid 201 compresses leakage hole by Sealing 201c from outer side covers sealing.Accordingly, in the middle of the outside of leakage hole, leakage hole and the inboard three aspects: of leakage hole leakage hole is completed to sealing and plugging simultaneously.
