Embodiment
For technological means, creation characteristic that the present invention is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the present invention.
Example 1
Referring to Fig. 1, leak stopping that this example provides nail 100 comprises that mainly nail bar 104 and leak stopping overlap 105 two-part.The cross section of leak stopping cover 105 is "T"-shaped, is made up of leak stopping lid 101 and the leak stopping bar 102 that is arranged on the leak stopping lid 101, and leak stopping lid 101 is used 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 the 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 bar in leak stopping cap 103 and the leak stopping cover cooperates, the port sidewall blocking of leak stopping cap is leaked bar and is driven integral body towards inner-walls of duct (namely revealing a mouthful direction) deformation, and this deformation sidewall covers leakage hole from interior side compression and the sealing of leakage hole.
This scheme in the specific implementation, the leak stopping lid 101 in the leak stopping cover 105 is used for covering the outside of seal leakage mouth, it is whole to be the bow body structure, arc shaped surface 101a is used for the operation of outer bound pair leak stopping lid 101, as presses pressure etc. as the fore side of leak stopping lid 101.Leak stopping lid 101 is positioned at the leakage hole outside, and the slick and sly structure of its arc can also effectively be avoided the problem (as, the scuffing that is caused by corner angle, problem such as puncture) of the damage that other structure (as square, polygonal etc.) causes on-the-spot other parts of leak stopping easily.
The plane 101b of the leak stopping lid 101 of bow body structure is used for living whole leakage hole and peripheral part thereof from outer side covers when leak stopping as the coverage rate 101b of leak stopping lid.
In order to guarantee that leak stopping lid 101 covers and the sealing effect in the seal leakage mouth outside, coverage rate 101b is provided with a sealed member 101c, joins by the sealing between sealing parts 101c realization coverage rate 101b and leakage hole and the peripheral part thereof.
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 compressing of leak stopping lid 101, can play the effect of enhanced leaktightness equally.
So the leak stopping of structure lid 101 generally can adopt the material with certain deformability to form, can produce corresponding deformation at different pipelines like this, make when leak stopping lid 101 covers sealing, coverage rate 101b on it matches with the pipe shape at leakage hole place, reaches perfect covering sealing.
Leak stopping bar 102 is used for passing leakage hole, and leak stopping cap 103 is sent into the 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.
This leak stopping bar 102 is vertically set on the coverage rate 101b of leak stopping lid 101, and is providing a through hole 102a who runs through leak stopping bar 102 and leak stopping lid 101 along its bearing of trend.This leak stopping bar 102 comprises that mainly the 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 when being used for leak stopping and reveals mouth, leakage hole is carried out directly preliminary leak stopping, and the length of the 102b of leak stopping section is for this reason generally covered thickness and the pipeline wall thickness sum of layer 101c that be bonded and sealed on 101 greater than leak stopping.
In order to reach stable deformation effect, transition structure 102d on the leak stopping bar 102 between mobile section 102c and the leak stopping section 102b is an arc transiting surface, by the slick and sly progressive formation of arc transiting surface, both guaranteed the reliability of leak stopping cap 103 sidewall deformation, be convenient to operation again.
In this example, nail bar 104 matches with the through hole 102a that leak stopping is overlapped in 105, and among the whole through hole 102a that movably is located on the leak stopping cover 105, and length is greater than the total length of leak stopping bar 102 with leak stopping lid 101.The front end of nail bar 104 is arranged on the neutral position of settling notch 103d bottom 103a on the leak stopping cap 103, realizes driving leak stopping cap 103 thus and moves along the mobile section 102c on the leak stopping bar 102.When nail bar 104 is located among the through hole 102a, the free end of nail bar 104 will cover 101 outer side surface from leak stopping and stretch out, follow closely bar 104 from the outside as long as spur like this, the leak stopping cap 103 that nail bar 104 will drive its front end moves towards leakage hole, and the mobile section 102c that makes leak stopping cap 103 be set in leak stopping bar 102 goes up and a mobile section 102c 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 the centre has the notch of arrangement 103d.The external diameter of leak stopping section 102b on the external diameter of leak stopping cap 103 and the leak stopping bar 102 is identical, the external diameter of mobile section 102c on the internal diameter of median slot 103d and the leak stopping bar 102 is identical, when the mobile section 102c that is set in leak stopping bar 102 when leak stopping cap 103 goes up 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 the leakage hole, also avoid the external diameter difference to cause secondary to destroy to the leak stopping mouth.The external diameter of mobile section 102c on the internal diameter of leak stopping cap 103 median slot 103d and the leak stopping bar 102 can be inequality as required.
Deformation can take place for the arc transiting surface 102d of sidewall 103b on leak stopping bar 102 that guarantees leak stopping cap 103 drives, the degree of depth of this leak stopping cap 103 (namely settling the degree of depth of notch 103d) enters into the length of leakage hole inboard greater than leak stopping bar 102, guarantee that leak stopping cap 103 has sufficiently long stroke along mobile section 102c when leakage hole moves, make the sidewall 103b of leak stopping cap 103 ports to contact with the arc transiting surface 102d on the leak stopping bar 102, the whole generation towards the deformation of inner-walls of duct (namely revealing a mouthful direction) under the effect of arc transiting surface 102d, and the part of generation deformation 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 that matches with arc transiting surface 102d, when both contact, by both cooperations, make leak stopping cap 103 sidewalls be more prone to take place deformation like this, and reliable and stable, avoid rupturing 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 the operation of assigning to leakage hole like this.
Because need produce certain deformation during 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 carried out leak stopping, concrete operating procedure was as follows:
(1) will follow closely bar 104 is located among the through hole 102a on the 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 the leak stopping cover 105, finish the assembling of leak stopping nail thus.
(2) leak stopping being followed closely integral body assigns in the leakage hole 301, make leak stopping bar 102 pass leakage hole 301 together with sheathed leak stopping cap 103 thereon, leak stopping on leak stopping bar 102 lid 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), the leak stopping section 102b of leak stopping this moment bar 102 assigns in the leakage hole 301, its outer side wall will fully push the inwall of leakage hole 301, blocks in leakage hole 301.
(3) withstand leak stopping lid 101 towards leakage hole, make leak stopping lid 101 by the outside that Sealing 101c compresses pipeline 300, avoid its back side leakage hole to move.
(4) spur nail bar 104 outside the lateral, nail bar 104 will drive leak stopping cap 103 and move to leakage hole 301 along the mobile section 102c on the leak stopping bar 102, reach the bottom 103a of leak stopping cap 103 until the top of mobile section 102c.
(5) referring to Fig. 3, in the moving process, when the sidewall 103b of leak stopping cap 103 ports contacts with arc transiting surface 102d on the leak stopping bar 102, wholely under the effect of arc transiting surface 102d produce towards inner-walls of duct (namely revealing a mouthful direction) open deformation and can not rupture; After the deformation part 103g of this generation deformation reaches certain length, the inner-walls of duct around the leakage hole be will push down, thereby whole leakage hole and peripheral part thereof covered, when acquiring a certain degree, pressure will form sealing; In the process, the pressure of the inner-walls of duct of deformation part 103g is except being moved by leak stopping cap 103 thrust of generation, the pressure of flowing medium will be to the pressure of deformation part 103g product towards inner-walls of duct in the pipeline, make deformation part 103g further to seal and compress inner-walls of duct, avoid medium to flow to leakage hole from the contacting point between deformation part 103g and the inner-walls of duct.
(6) the leak stopping hat becomes part 103g and compresses leakage hole when inboard in sealing, and its pressure will make tube wall mobile towards the leak stopping lid in the outside, because leak stopping lid 101 is withstood, leak stopping lid 101 compresses leakage hole by Sealing 101c from outer side covers and sealing.Accordingly, in the middle of the outside of leakage hole, leakage hole and inboard three aspects of leakage hole simultaneously leakage hole is finished sealing and plugging.
Example 2
Referring to Fig. 4, leak stopping that this example provides nail 200 comprises that mainly 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 cooperates with the free end 202b of leak stopping bar, drive the free end integral body of leak stopping bar towards inner-walls of duct (namely revealing a mouthful direction) deformation, and make deformations cover leakage hole from interior side compression and the sealing of leakage hole.
This scheme in the specific implementation, the leak stopping lid 201 in the leak stopping cover 205 is used for compressing the outside that covers the seal leakage mouth, it is whole to be the bow body structure, arc shaped surface 201a is used for the operation of outer bound pair leak stopping lid 201 as the fore side of leak stopping lid 201, as roof pressure etc.Because leak stopping lid 201 is positioned at the leakage hole outside, the slick and sly structure of its arc can also effectively be avoided the problem (as, the scuffing that is caused by corner angle, problem such as puncture) of the damage that other structure (as square, polygonal etc.) causes on-the-spot other parts of leak stopping easily.But leak stopping lid 201 is not limited to this structure.
The plane 201b of the leak stopping lid 201 of bow body structure is used for living whole leakage hole and peripheral part thereof from outer side covers when leak stopping as the coverage rate 201b of leak stopping lid.
In order to guarantee that leak stopping lid 201 covers and the sealing effect in the seal leakage mouth outside, coverage rate 201b is provided with a sealed member 201c, joins by the sealing between sealing parts 201c realization coverage rate 201b and leakage hole and the peripheral part thereof.
For the layer that is bonded and sealed that sealing parts 201c specifically can adopt some sealers or other sealing compound to constitute, specifically decide according to the material of pipeline and medium and the pressure medium size of Qi Nei, as long as can guarantee to seal the effect of joining.
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 compressing of leak stopping lid 201, can play the effect of enhanced leaktightness equally.
So the leak stopping of structure lid 201 generally can adopt the material with certain deformability to form, can produce corresponding deformation at different pipelines like this, make when leak stopping lid 201 covers sealing, coverage rate 201b on it matches with the pipe shape at leakage hole place, reaches perfect covering sealing.
Leak stopping bar 202 is vertically set on the coverage rate 201b of leak stopping lid 201, and is providing a through hole 202a who runs through leak stopping bar 202 and leak stopping lid 201 along 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 leak stopping bar 202 can not rupture when deformation.
In this example, nail bar 204 matches with the through hole 202a that leak stopping is overlapped in 205, and among the whole through hole 202a that movably is located on the leak stopping cover 205, and length is greater than the total length of leak stopping bar 202 with leak stopping lid 201, and the front end at nail bar 204 arranges guide pad 203 simultaneously.Thus, when nail bar 204 is located among the through hole 202a, the free end of nail bar 204 will cover 201 outer side surface from leak stopping and stretch out, follow closely bar 204 from the outside as long as spur like this, 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, make the whole deformation that the free end 202b of leak stopping bar 202 (namely reveals a mouthful direction) along the guide surface 203a generating plane of guide pad 203 to inner-walls of duct, 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 require to decide according to reality.The top of upper cone 203c joins with nail bar 204 in the guide pad 203 of this bicone structure, and its conical surface 203a is used for the free end 202b of leak stopping bar is cooperated as the guide surface 203a of guide pad 203.Because guide surface 203a is the conical surface with certain angle of inclination, when guide pad 203 in the leakage hole moving process, the top of guide surface 203a at first 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 one towards the extruding force that increases gradually in 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, because guide surface 203a is the conical surface of gradual change, it can contact all around simultaneously with free end 202b inwall, then can be to applying the extruding force of identical gradual change around the free end 202b inwall simultaneously, thereby make that 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 gradually and move towards leakage hole, until the inner side surface contact of deformations 202c and compress pipe inner wall.
When guide pad 203 displacement distances reached 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 and the sealing of leakage hole.
The concrete angle of this guide surface 203a can be decided 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 cooperate.
Be generally cone for the cone in the guide pad 203 of bicone structure, also can adopt other multiaspect cones as required.
When the leak stopping nail 200 that utilizes such scheme to form carried out leak stopping, concrete operating procedure was as follows:
(1) will follow closely bar 204 is located among the through hole 202a on the 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, finish the assembling of leak stopping nail thus.
(2) leak stopping being followed closely integral body assigns in the leakage hole 301, make leak stopping bar 202 pass leakage hole 301 together with the guide pad 203 on the nail bar 204, leak stopping on leak stopping bar 202 lid 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), leak stopping this moment bar 202 assigns in the leakage hole 301, its outer side wall will fully push the inwall of leakage hole 301, blocks in leakage hole 301.
(3) withstand leak stopping lid 201 towards leakage hole, make leak stopping lid 201 by the outside that Sealing 201c compresses pipeline 300, avoid its back side leakage hole to move.
(4) spur nail bar 204 outside the lateral, nail bar 204 will drive guide pad 203 and move towards leakage hole 301.
(5) referring to Fig. 6, in the 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 towards inner-walls of duct (namely revealing a mouthful direction) open deformation and can not rupture making that the free end 202b of leak stopping bar is whole; After the deformation part 202c of this generation deformation reaches certain length, the inner-walls of duct around the leakage hole 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, the pressure of the inner-walls of duct of deformation part 202c is except deformation power, the pressure of flowing medium will be to the pressure of deformation part 202c product towards inner-walls of duct in the pipeline, make deformation part 202c further to seal and compress inner-walls of duct, avoid medium to flow to leakage hole from the contacting point between deformation part 202c and the 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, because leak stopping lid 201 is by the top, leak stopping lid 201 compresses leakage hole by Sealing 201c from outer side covers and sealing.Accordingly, in the middle of the outside of leakage hole, leakage hole and inboard three aspects of leakage hole simultaneously leakage hole is finished sealing and plugging.
According to the characteristics of above-mentioned example, it in use has the following advantages:
