Description
Technical field
The utility model belongs to pipeline field, relates in particular to a kind of novel 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.
Existing pipeline compensator generally comprises bellows layer and coat of metal; and being generally thinner metallic conduit, makes coat of metal; its poor toughness of the compensator of this structure; the convergent-divergent scope of bellows is less causes compensation not; affect the normal operation of delivering pipe, the working life of having reduced pipeline.
Model utility content
For existing pipeline compensator poor toughness, compensation not, the utility model provide a kind of toughness strong, compensate large novel pipeline compensator.
The technical solution of the utility model is as follows:
A kind of novel pipeline compensator, comprise the bellows of teflon material, flange plate and the connecting rod that is connected two flange plate at bellows two ends, connecting rod two ends are connected with nut, the skin of described polytetrafluoroethylbellows bellows is provided with layer of metal net protective layer, and described wire netting protective layer is connected between flange plate and bellows; Described wire netting protective layer is one or more layers; The cylindrical side of described flange plate is provided with pulling block, and pulling block inwall is provided with screw thread, and the locking of working in coordination of pulling block inner thread and connecting rod two ends outside thread, described pulling block and flange plate welding, and described pulling block is at least three; Bellows two-port inwall is provided with the connection mouth of taper, on the connection mouth of taper, connecting tube is housed.
As preferably, the bellows of described teflon material is provided with net, and net is provided with at least two-layer.
Preferably, the superficies of described polytetrafluoroethylbellows bellows are provided with insulating in composition.
As preferably, described wire netting protective layer is one or more layers.
As preferably, between described bellows two-port inwall and connecting tube, overlap and have seal ring.
The beneficial effects of the utility model: the utility model is simple in structure, bellows skin arranges wire netting protective layer and can not only protect the bellows can be not damaged, but also can not affect the compensation space of bellows, practical.
Brief description of the drawings
Fig. 1 is the utility model structural representation.
Embodiment
A kind of novel pipeline compensator as shown in Figure 1; comprise the bellows 1 of teflon material, flange plate 2 and the connecting rod 3 that is connected two flange plate 2 at bellows 1 two ends; connecting rod 3 two ends are connected with nut; the skin of described polytetrafluoroethylbellows bellows 1 is provided with layer of metal net protective layer 4, and described wire netting protective layer 4 is connected between flange plate 2 and bellows 1.Described wire netting protective layer 4 is one or more layers.The bellows 1 of described teflon material is provided with net, and net is provided with at least two-layer.The cylindrical side of described flange plate 2 is provided with pulling block 5, and described pulling block 5 is three, and described pulling block 5 and flange plate 2 weld.Pulling block 5 inwalls are provided with screw thread, and the locking of working in coordination of pulling block 5 inner threads and connecting rod 3 two ends outside threads.The superficies of described polytetrafluoroethylbellows bellows 1 are provided with insulating.Between described bellows 1 two-port inwall and connecting tube, cover has seal ring.Bellows 1 two-port inwall is provided with the connection mouth of taper, on the connection mouth of taper, connecting tube is housed.
The utility model is simple in structure, and bellows skin arranges wire netting protective layer and can not only protect the bellows can be not damaged, but also can not affect the compensation space of bellows, practical.
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.
