Specific embodiment
A specific embodiment is lifted with reference to the accompanying drawing, and the utility model is described in detail.
As shown in Figure 1, a kind of pipe-repairing, including pipeline body 1, sealant layer 4, rubber sealant 2 and stiffening ring
Shape adjusts component.
Pipeline body 1 is pipeline to be repaired, that is, contains pipeline dislocation or/and pipeline gap, dislocation is mainly pipeline
For interface because of differential settlement between tube coupling caused by Geological Differences, pipeline gap refers mainly to the gap of adjacent tubes internode at pipe joint
The gap formed with inner wall of the pipe crackle.As Fig. 6 illustrates the operating condition that adjacent tubes internode at pipe joint has gap, the present embodiment
It is illustrated with the operating condition.It is filled with sealant in pipeline gap and forms sealant layer 4.In the present embodiment, sealant layer 4 is adopted
With the non-sagging type polysulfide sealant of two-component.
For rubber sealant 2 using multiple tooth formula is used, pipeline gap is located therein region, the thickness root of rubber sealant 2
It is specifically determined according to parameters such as the caliber of pipeline body 1, fluid pressures.Sealing ring, waterstop etc. can be used in rubber sealant 2, this
Multiple tooth formula neoprene packing circle is used in embodiment.As shown in Figure 5 and Figure 6, rubber sealant 2 covers pipeline gap and to pipe
Road gap two sides extend, and the both sides of rubber sealant 2 respectively pass through a rigid annular shaped adjusting component and are fixed on pipeline body 1.
Rigid annular shaped adjusts the second internal expension ring 32 and expansion board that component includes the first internal expension ring 31 of stainless steel material, stainless steel material
33。
Two ends of the first internal expension ring and the second internal expension ring are separately connected to form first connecting portion and second connecting portion.Its
Middle first connecting portion as shown in Fig. 2, the end of the first internal expension ring and the second internal expension ring at clamping relationship.
Second connecting portion is as shown in Figure 3 and Figure 7, and the first internal expension ring and the second internal expension ring are connected by expansion board 33, specifically
Ground is said, is respectively equipped with adjusting grooves, expansion board 33 on the end of corresponding first internal expension ring of second connecting portion and the second internal expension ring
Protrusion is adjusted with being respectively equipped on the joint face of the first internal expension ring and the second internal expension ring, adjusting protrusion can be recessed from different adjustings
Slot matching, and in the axial direction, two ends of expansion board 33 are in a wide narrow shape.Such as Fig. 7, in order to enhance expansion board 33
Intensity, multiple adjustings protrusion is respectively provided on two face, in connection, it is recessed that multiple adjustings protrusions are caught in corresponding adjusting
Slot reduces the single stress for adjusting protrusion and bearing.It, can be by adjusting expansion board 33 and the first internal expension ring and the when therefore installing
The relative positional relationship of two internal expension rings come adjust rigid annular shaped adjust component outer profile size, to adjust rubber sealant 2
With the tightening degree of pipeline, to reach sealing effect.
When practical application, the relatively narrow end of expansion board 33 towards the side close to pipeline gap, adjust protrusion first with it is separate
The adjusting grooves in pipeline gap match, if revealing again at the pipeline gap in use of the pipeline after reparation, Huo Zhe
The tightness degree for finding that rubber sealant 2 is bonded with pipeline body 1 when maintenance is not up to standard, then the position of expansion board 33 is adjusted,
Adjusting protrusion is set to be caught in the adjusting grooves closer to pipeline gap side, to expand the outer profile that rigid annular shaped adjusts component, from
And increase its pressure to sealant, and then enhance the tightness degree that sealant is bonded with pipeline body 1, realize sealing effect.
Second connecting portion as shown in Figure 3 further includes two expander stressed plates 34, and expander stressed plate 34 is respectively and fixedly connected to
The end of first internal expension ring and the second internal expension ring, when installing expansion board 33, the expander stressed member is expander in first
Stress seating surface is provided on tensioner ring and the second internal expension ring, expander will be swollen in corresponding first internal expension ring of second connecting portion and second
The end of ring is separated to suitable distance, then installs expansion board 33.Rigid annular shaped adjusts component in order to facilitate the installation of, in first
Positioning protrusion 311 is provided on tensioner ring and the second internal expension ring, and provided with corresponding with positioning protrusion 311 on rubber sealant 2
Positioning groove 21, for rigid annular shaped adjust component Primary Location.As shown in Figure 1 and Figure 4, two positioning grooves 21 are symmetrical
Setting.In a circumferential direction, the size of positioning groove 21 is greater than the size of its corresponding positioning protrusion 311, which is mainly
In order to realize the self-regulation between internal expension ring and rubber sealant 2, prevent from adjusting the size that rigid annular shaped adjusts component outer profile
When rubber sealant 2 be broken.The thickness of first internal expension ring, the second internal expension ring and expansion board 33 is according to the pipe of pipeline body 1
The parameters such as diameter, fluid pressure specifically determine.
Pipe-repairing provided by the utility model does not need to carry out the operation such as punching on pipeline body 1, does not also need outer
Add the connectors such as bolt, structural damage will not be caused to pipeline body 1.Again since its rubber sealant 2 is by rubber material system
At with ductility, therefore repaired pipeline, the pipeline especially repaired between the interface tube coupling have error resilience position
Ability, thus repaired pipeline provided by the utility model has preferably anti-let out relative to traditional repaired pipeline
Leak effect.
Disclosed above is only the specific embodiment of the application, and however, this application is not limited to this, any this field
Technical staff can think variation, should all fall in the protection domain of the application.
