Abstract
The utility model belongs to the field of pipelines, and provides a pipeline compensator which can not be easily damaged and aims to solve the problem that an existing pipeline is prone to damaging due to thermal expansion and cold contraction. The pipeline compensator comprises a corrugated pipe body, a pull rod and flange discs arranged at the two ends of the corrugated pipe body. A net sleeve is arranged in the corrugated pipe body, a heat insulation layer is arranged on the outer side surface of the corrugated pipe body and filled with aluminum silicate fiber cotton, pull rod connection blocks are welded to or integrally connected to the peripheries of the two flange discs, and the pull rod connection blocks are provided with through holes. The pull rod connection blocks on the two flange discs are connected through the pull rod, threads are arranged at the two ends of the pull rod respectively. The pipeline compensator has the advantages that the structure is simple, the pipeline compensator is arranged between pipelines so that the problem that the pipelines are damaged due to thermal expansion and cold contraction can be effectively solved, and the service life of the pipelines can be longer.
Description
Technical field
The utility model belongs to pipeline field, relates in particular to a kind of pipeline compensator.
Background technique
Daily supplies cold air, heating installation all adopt pipeline transport mode, and tap water, rock gas and oil etc. all adopt pipeline to transport, and because pipeline can expand with heat and contract with cold, are easy to cause the damage of pipeline, cause very large loss.
Model utility content
Easily cause the damage of pipeline because expanding with heat and contract with cold for existing pipeline, the utility model provides one to make the non-damageable pipeline compensator of pipeline.
The technical solution of the utility model is as follows:
A kind of pipeline compensator, comprise bellows body, the flange plate at pull bar and bellows body two ends, in bellows body, be provided with net, bellows body outer surface is provided with insulating, in insulating, be filled with aluminosilicate fiber cotton, described two flange plate peripheries weld or are connected with pull bar contiguous block, described pull bar contiguous block is provided with through hole, pull bar contiguous block on two flange plate connects by pull bar, and pull bar two ends are equipped with screw thread, described pull bar comprises upper connecting rod and lower link, be provided with two upper boom pin holes in the lower end of described upper connecting rod, be provided with the lower beam pin hole identical with pitch-row with pin hole size on upper connecting rod in the upper end of described lower link, between upper connecting rod and lower link, clamp by two pins, pull bar contiguous block on two described flange plate is six, flange plate is provided with attachment hole.
Further, on the internal diameter of bellows body two ends, seal ring is installed, the internal diameter of seal ring is less than the internal diameter of the flange plate at bellows body two ends.
Further, seal ring being installed on the internal diameter of described seal ring bellows body two ends is an O type rubber seal.
As preferably, also comprise the metal supporting rings for supporting net, described metal supporting rings is located in net.
The beneficial effects of the utility model: the utility model is simple in structure, the utility model pipeline compensator is installed between pipeline and can be effectively alleviated the pipeline damage to pipeline bringing of expanding with heat and contract with cold, make pipeline longer service life, pull bar is designed to upper and lower interface arrangment, make the length of pull bar can carry out as required suitable replacing, and pull bar adopts upper and lower interface arrangment to make replacing pull rod convenient, only need to change a wherein pull bar.
Brief description of the drawings
Fig. 1 is the utility model structural representation.
Embodiment
A kind of pipeline compensator as shown in Figure 1, comprise the flange plate 3 at bellows body 1, pull bar 2 and bellows body two ends, in bellows body 1, be provided with net, bellows body 1 outer surface is provided with insulating, in insulating, be filled with aluminosilicate fiber cotton, flange plate is provided with described in attachment hole two flange plate 3 peripheries welding or is connected with pull bar contiguous block 4, described pull bar contiguous block 4 is provided with through hole, pull bar contiguous block 4 on two flange plate 3 connects by pull bar 2, and pull bar 2 two ends are equipped with screw thread.Described pull bar comprises upper connecting rod and lower link, be provided with two upper boom pin holes in the lower end of described upper connecting rod, be provided with the lower beam pin hole identical with pitch-row with pin hole size on upper connecting rod in the upper end of described lower link, between upper connecting rod and lower link, clamp by two pins, two pull bars connect by pin, the height of pull bar is changed the pull bar of different heights as required, pull bar only need replace with pull bar or lower link, replacing pull rod is convenient, fast, on bellows body 1 two ends internal diameter, seal ring is installed, the internal diameter of seal ring is less than the internal diameter of the flange plate 3 at bellows body two ends, it is an O type rubber seal that seal ring is installed on the internal diameter of described seal ring bellows body two ends, also comprise for also comprising the metal supporting rings for supporting net, described metal supporting rings is located in net, pull bar contiguous block 4 on two described flange plate 3 is six, flange plate 3 is provided with attachment hole.
The utility model is simple in structure, the utility model pipeline compensator is installed between pipeline and can be effectively alleviated the pipeline damage to pipeline bringing of expanding with heat and contract with cold, and makes pipeline longer service life.The above is only preferred embodiments of the present utility model, and the equivalence of doing according to structure, feature and principle described in the utility model the scope of the claims therefore all changes or modifies, and is included in the utility model patent claim.
