, below will be right in order to illustrate more clearly of the utility model embodiment or technical scheme of the prior art
The accompanying drawing used required in embodiment or description of the prior art is briefly described.In all of the figs, it is similar
Element or part are general by similar reference mark.In accompanying drawing, each element or part might not be according to actual ratios
Draw.
Fig. 1 is the structural representation of the wall-penetrating type pipeline protection device of the utility model embodiment.
Embodiment
To be fully understood by the purpose of this utility model, feature and effect, implement below in conjunction with accompanying drawing to of the present utility model
Example be described in detail, it should be noted that specific embodiment described herein only to explain the utility model, and
It is not used in restriction the utility model.
Fig. 1 is the structural representation of the wall-penetrating type pipeline protection device of the utility model embodiment.The wall-penetrating type pipeline is protected
Protection unit part direct-burried is in wall, similar to through wall.As shown in figure 1, the wall-penetrating type pipeline protection device 10 includes set
It is located at the outer direct burial sleeve pipe 2 of pipeline 1 (such as flow pipe, heating pad pipe), the guarantor being arranged between direct burial sleeve pipe 2 and pipeline 1
Warm sealant 5.Wherein, thermal-insulating sealing layer 5 can elect wound form as located at the spunyarn between direct burial sleeve pipe 2 and pipeline 1, should
Spunyarn can have insulation concurrently and cannula tip seals the effect of waterproof.It is easily understood that thermal-insulating sealing layer 5 may also be other cloth
The material of mode is put, such as pitch or pitch are combined with above-mentioned spunyarn.The above-mentioned direct burial sleeve pipe 2 of pipeline 1 by direct-burried in wall,
Pipeline 1 can be avoided in use, disturbance is caused to building, while being easy to the I&M of pipeline 1.Meanwhile, above-mentioned insulation
Sealant 5 can not only prevent external object (such as vapor) from entering between wall-penetrating type pipeline protection device 10 and wall, and
And the insulation to pipeline 1 and sealing function can be realized, prevent external object from entering pipeline 1 and influenceing pipeline life.
Wall-penetrating type pipeline protection device 10 also includes exposed telescopic component.Wherein, it is so-called exposed to mean to bury
Enter the part in wall.The exposed telescopic component includes being sheathed on the bellows 4 that pipeline 1 is outer and with direct burial sleeve pipe 2 is connected,
And the plug members 7 being connected with the end away from direct burial sleeve pipe 2 on bellows 4.Wherein, the plug members 7 matchingly cover
Outside pipeline 1 so that the endoporus of plug members 7 is intactly engaged with the periphery wall of pipeline 1, to prevent external substance from passing through the two
Composition surface.Wherein, the plug members 7 preferably block wing ring, and the radial dimension of the closure wing ring had both been more than the maximum of bellows 4
Radial dimension, is more than the radial dimension of direct burial sleeve pipe 2 again.Those skilled in the art can according to the running temperature of pipeline 1 and
The length of pipeline 1 calculates the thermal expansion length of pipeline 1, and selects suitable bellows based on the thermal expansion length, belongs to this
The routine techniques in field, will not be repeated here for the sake of saving length.
According to the utility model, the wall-penetrating type pipeline protection device 10 can be compensated by the elastic deformation function of bellows and managed
Axial, angular, lateral and combinations thereof the displacement that road is produced due to thermal deformation, mechanically deform and various mechanical oscillation, it is and existing
Technology, which is compared, can effectively improve flexible and vibration the ability of the device extraction duct, to reduce the threat to building.Together
When, plug members 7 can block the end of bellows 4, to play a part of sealing waterproof.Bellows 4 can be metal bellows,
But it is preferred to use stainless steel metal bellows.Metal bellows has preferable elasticity, pressure, axial force, cross force or
Displacement can be produced under Moment, can be installed on as a kind of flexible pressure-resistant pipe fitting in liquid/gas induction system, to compensate
Pipeline or machine, the mutual displacement of equipment connection end, absorb vibrational energy, can play a part of vibration damping.And metal bellows
In stainless steel metal bellows there is very high bending fatigue strength and corrosion resistance, welding performance is good, and material cost compared with
It is low.
Above-mentioned exposed telescopic component may also include to be led on linking wing ring 6, bellows 4 close to the end of direct burial sleeve pipe 2
The connection direct burial of linking wing ring 6 sleeve pipe 2 is crossed, the radial dimension of linking wing ring 6 had both been more than the maximum radial dimension of bellows 4, again
More than the radial dimension of direct burial sleeve pipe 2.It is connected the laminating metope of wing ring 6, it is possible to achieve to the fixation of device, play simultaneously
Protect the effect of bellows 4.
Wall-penetrating type pipeline protection device 10 also includes the fixed location wing ring 3 being enclosed on outside direct burial sleeve pipe 2, the location wing
The combination that ring 3 can allow between direct burial sleeve pipe 2 and wall it is even closer, make direct burial sleeve pipe 2 more consolidate, also, also
Infiltration leak of the water between direct burial sleeve pipe 2 and wall can be prevented.Preferably, between location wing ring and direct burial sleeve pipe
It is connected as welding.Similarly, the connection between plug members 7 and bellows 4 can be welding, between linking wing ring 6 and bellows 4
Connection and linking wing ring 6 and direct burial sleeve pipe 2 between connection can be all welding, it is easy to operate.It is easily understood that above-mentioned
Welding can also be replaced by integral type manufacture.
In summary, the wall-penetrating type pipeline protection device of the utility model embodiment can effectively improve wall-penetrating type pipeline guarantor
Flexible and vibration the ability of protection unit extraction duct, to reduce the threat to building.
Although the utility model is described by reference to preferred embodiment, model of the present utility model is not being departed from
In the case of enclosing, various improvement can be carried out to it and part therein can be replaced with equivalent.Especially, as long as not depositing
The every technical characteristic being previously mentioned in structural hazard, each embodiment can combine in any way.The utility model
It is not limited to specific embodiment disclosed herein, but all technical schemes including falling within the scope of the appended claims.
