Description
Technical field
The utility model relates to technical field of pipeline connection, specifically, being related to a kind of pipeline telescopic device.
Background technique
In modern industry, the pipe-line system that pipeline is constituted is more and more huger, and application field is also more and more extensive.Pipeline is stretched
Contracting device is the connection attachment recompensed in pipeline connection due to change in size caused by expanding with heat and contract with cold, and avoids pipeline cold because of heat expansion
Compression deformation fracture, protective conduit.
There are two types of pipeline telescopic device is most common, one is rubber pipeline telescopic device, another kind is metal tubes expansion bend.
The bearing temperature of rubber pipeline telescopic device is lower, and receiving pressure is smaller, and stroke is also small, and service life is short, poor safety performance；Gold
Belong to pipeline telescopic device to be mainly characterized by flexible compensation amount big, bearing temperature is high, bears that pressure is big, and current metal tubes are flexible
Device generallys use stainless steel and is made into bellows, when pipe expansion, impact force is generated to corrugated stainless steel tubing, when intensity reaches tired
Pipeline will be broken when labor intensity, and the weld bond of pipeline is easy to crack and can not repair when if there is torsional forces.
Carbon steel material there are also some Telescopic metal devices, although some sparies paint, be exposed to the position of outside with
And the position with pipeline fluid media contact, the natural environments such as long-time weather and medium leaching corrosion, easily cause corrosion,
Rot or leak etc., service life is low, inevitably generates resources loss.
Utility model content
The purpose of this utility model is to provide a kind of pipeline telescopic device, to solve above-mentioned technical problem.
To solve the above problems, the technical scheme adopted by the utility model is
A kind of pipeline telescopic device, including telescoping tube, the telescoping tube tube body outer sheath are equipped with power disk, the telescoping tube tube body
End, power disk outer sheath be equipped with extrusome, fastened between the power disk and extrusome by power valve snail bolt-lock, it is described stretch
It is attached between pipe, power disk and extrusome three by caging bolt；It is equipped between power disk end, power disk and extrusome
Ring-shaped rubber sealing member sheathing is on the outside of the telescoping tube tube body.
It is preferred: the outer surface and the internal portion with pipeline fluid media contact of the telescoping tube, power disk and extrusome
Position is coated with enamel layer.
The utility model has the advantages that compared with prior art, pipeline telescopic device described in the utility model has the advantage that
1, sealing effect is good: on the outside of telescoping tube tube body, between power disk and extrusome, it is set with ring-shaped rubber sealing element,
Annular rubber seal, which is compressed, by power disk realizes that groove face seam crossing fastens soft seal between telescoping tube, power disk and extrusome,
Play the role of preventing fluid media (medium) leakage extravasation.
2, long service life: telescoping tube, power disk, the outer surface of extrusome and the internal institute with pipeline fluid media contact
There is position, all have passed through a series of special process processing of the enamel application of slip, be attached to enamel layer uniformly on steel structure surface, make to produce
Product are with surface enamel layer is smooth, be not easy contamination dirt, non-corrosive, reduces blocking, corrosion-resistant, high temperature resistant, erosive wear resistant, use
The advantages that service life is long.
3, safe and reliable: steel construction material realizes expansion bend to engineering pipeline by adjusting the distance of caging bolt nut
Expansion is shunk and the functions such as cushion stroke size, length, is eliminated pipeline drawn expanded, is shunk iso-stress bring and influence, prevents
Pipeline makes pipe-line system deform and be broken because expanding with heat and contract with cold, and safety coefficient is high.
Detailed description of the invention
Fig. 1 is a kind of structural schematic diagram of embodiment of the utility model.
Specific embodiment
The utility model is described in further detail with reference to the accompanying drawings and detailed description
Embodiment:
Referring to Fig.1, pipeline telescopic device described in the present embodiment, including telescoping tube 1,1 tube body of telescoping tube outside suit
Strong disk 2, the 1 tube body end of telescoping tube, power disk 2 outer sheath extrusome 5 is housed, lead between the power disk 2 and extrusome 5
Exertin valve snail bolt 3 is locked, and is attached between 5 three of the telescoping tube 1, power disk 2 and extrusome by caging bolt 7.
It is equipped with ring-shaped rubber sealing element 4 between 2 end of power disk, power disk 2 and extrusome 5 and is sleeved on the telescoping tube 1
On the outside of tube body.
The telescoping tube 1, the outer surface of power disk 2 and extrusome 5 and the internal position with pipeline fluid media contact are equal
It is coated with enamel layer 6.
Telescoping tube 1 is in most inner side when Product Assembly, and power disk 2 is inserted on the outside of 1 tube body of telescoping tube, on the outside of 1 tube body of telescoping tube
It is inserted in ring-shaped rubber sealing element 4, then extrusome 5 is inserted in the outside of 1 tube body end of telescoping tube, power disk 2, then firmly valve snail bolt
3 lock power disk 2 and extrusome 5, by power disk 2 compress annular rubber seal 4 telescoping tube 1, power disk 2 and extrusome 5 it
Between realize groove face seam crossing fasten soft seal.
Telescoping tube 1, power disk 2, the outer surface of extrusome 5 and the internal all sites with pipeline fluid media contact, all
It has passed through a series of special process processing of the enamel application of slip, be attached to enamel layer 6 uniformly on steel structure surface.
It is attached between 5 three of telescoping tube 1, power disk 2 and extrusome with caging bolt 7, and spiral shell can be limited by adjusting
The distance of 7 nut of bolt, realize expansion bend to engineering pipeline expansion, shrink and the functions such as cushion stroke size, length, eliminate pipeline
Drawn expanded shrinks the influence of iso-stress bring, prevents pipeline from so that pipe-line system is deformed and is broken because expanding with heat and contract with cold.
This pipeline telescopic device is when engineering construction is installed, by the telescoping tube 1 and extrusome 5 of the expansion bend finished product assembled
Ring flange (ring flange contact surface should install rubber seal) and engineering pipeline ring flange with bolt carries out two-by-two locking connection
?.
The above is only the embodiments of the present invention, and therefore it does not limit the scope of the patent of the utility model, all benefits
The equivalent structure made by the utility model specification and accompanying drawing content is directly or indirectly used in other relevant technology necks
Domain, similarly within the scope of patent protection of the utility model.
