The utility model discloses can avoid pressing from both sides matter or granular medium entering bellows inner chamber, it is wear -resisting, resistant ultra -low temperature.
Description
Technical field
This utility model relates to a kind of pipe safety device, and specifically, this utility model relates to a kind of bellow-type expansion
Device.
Background technology
Corrugated expansion joint is big due to compensation dosage, is therefore widely used in industry pipe network.Existing corrugated expansion joint
Generally comprise corrugated tube, be fixedly and coaxially connected on the entrance point pipe at corrugated tube two ends and port of export pipe, entrance point inside pipe wall admittedly
The fixed horn mouth connected is towards the protecting pipe of import, and between this corrugated expansion joint protecting pipe and corrugated tube inner chamber, gap is relatively
Greatly, folder matter or granular medium are easily accessible in corrugated tube inner chamber, affect the contraction of corrugated tube, and also just impact is normal mends
Repaying, serious meeting damages corrugated expansion joint.
Summary of the invention
This utility model, for the deficiencies in the prior art, proposes one and is avoided that folder matter or granular medium enter ripple
Tube cavity, thus significantly extend the corrugated expansion joint of resistance to ultralow temperature in metal compensator service life.
This utility model is achieved through the following technical solutions technical goal.
The corrugated expansion joint of resistance to ultralow temperature, including corrugated tube, be fixedly and coaxially connected the entrance point pipe at corrugated tube two ends and
On port of export pipe, entrance point inside pipe wall, the fixing horn mouth connected is towards the protecting pipe of import, and corrugated tube two ends straight section is respectively
Coaxial package is on entrance point pipe, port of export pipe outer wall, and the axial length of protecting pipe is than ripple pipe range, and blocks ripple from structure
Stricture of vagina inside pipe wall does not contacts with particle media；It thes improvement is that: described protecting pipe stretches in port of export pipe orifice, fit
Port of export inside pipe wall and protecting pipe outer wall between be provided with radial seal structure.
In said structure, described radial seal structure includes the circle that cross section is U-shaped being fixedly connected on protecting pipe outer wall
Ring, the sealing ring being arranged in annulus, sealing ring closely cooperates with port of export inside pipe wall.
In said structure, coaxial package ring on the outer wall of described corrugated tube straight section, ring, corrugated tube straight section are respectively
With entrance point pipe, the fixing connection of port of export pipe outer wall, form reinforcing joint.
In said structure, described corrugated tube is that multi-layered sheet is compressing.
In said structure, at the described protecting pipe inwall fixing connection latticed net of thin-walled, in the space of described net
Fill, bond high-abrasive material.
In said structure, described high-abrasive material is wear-resistant ceramic mud.
This utility model compared with prior art, has the positive effect that:
1., during protecting pipe stretches into port of export pipe orifice, it is provided with between port of export inside pipe wall and the protecting pipe outer wall of fit radially
Sealing structure, so, corrugated tube inner chamber is just sealed, and folder matter or granular medium enter corrugated tube inner chamber, it is ensured that
The reliability that corrugated tube normally works, thus significantly extend corrugated expansion joint service life.
2. ring, corrugated tube straight section are fixed with entrance point pipe, port of export pipe outer wall respectively and are connected by welding manner, weldering
Seam fusion is integrally making the corrugated tube jointing intensity with entrance point pipe, port of export pipe be greatly improved, thus solves
The problem that the joint that under ultralow-temperature operation conditions, corrugated tube is connected with entrance point pipe, port of export pipe easily ftractures.
3. corrugated tube is that multi-layered sheet is compressing, is effectively increased the intensity of corrugated tube.
4. when medium flows through protecting pipe, the contact internal walls only formed with high-abrasive material in net, do not connect with protecting pipe inwall
Touch, the inwall that only abrasion high-abrasive material is formed, and the inwall that high-abrasive material is formed is the most wear-resisting, significantly extends protecting pipe and uses
In the life-span, corrugated expansion joint extends more than twice service life.
Accompanying drawing explanation
Fig. 1 is this utility model structural representation.
Fig. 2 is I part partial enlarged drawing in Fig. 1.
Fig. 3 is II part partial enlarged drawing in Fig. 1.
Detailed description of the invention
Below according to accompanying drawing and the utility model is described in further detail in conjunction with the embodiments.
The corrugated expansion joint of resistance to ultralow temperature shown in the drawings, including corrugated tube 3, is fixedly and coaxially connected at corrugated tube 3 two ends
Entrance point pipe 1 and port of export pipe 5, entrance point pipe 1 inwall on the fixing horn mouth connected towards the protecting pipe 2 of import, this reality
Executing in example, corrugated tube 3 is that multi-layered sheet is compressing, corrugated tube 3 two ends straight section coaxial package respectively at entrance point pipe 1, go out
On mouthful end pipe 5 outer wall, the axial length of protecting pipe 2 is longer than corrugated tube 3, and block from structure corrugated tube 3 inwall not with granule
Shape medium contacts；Protecting pipe 2 stretches in port of export pipe 5 endoporus, between port of export pipe 5 inwall and protecting pipe 2 outer wall of fit
Being provided with radial seal structure 4, radial seal structure 4 includes the annulus that cross section is U-shaped being fixedly connected on protecting pipe 2 outer wall
4.1, the sealing ring 4.2 being arranged in annulus 4.1, sealing ring 4.2 closely cooperates with port of export pipe 5 inwall.
Coaxial package ring 6 on the outer wall of corrugated tube 3 straight section, ring 6, corrugated tube 3 straight section respectively with entrance point pipe
1, port of export pipe 5 outer wall is fixing connects, and forms reinforcing joint.
Connect the latticed net of thin-walled 7 protecting pipe 2 inwall is fixing, fill in the space of net 7, bond high-abrasive material
