Abstract
The utility model discloses a direct-buried corrosion-resistant bidirectional compensator which is characterized by comprising a bellows, end connection pipes, a fixed annular plate, a pull rod, a guiding flange installed on the bellows, a pressing ring installed at the end of the bellows and pressing filler. Two ends of the bellows are connected with the end connection pipes respectively, a flow guide pipe is arranged in the bellows, an outer sheath is arranged on the outer portion of the bellows, and the surface of the bellows is provided with a corrosion-resistant layer. The direct-buried corrosion-resistant bidirectional compensator has the advantages of being high in corrosion-resistant performance and compact in structure, working reliably and being long in service life and capable of reducing production cost.
Description
Technical field
The utility model relates to a kind of direct buried anticorrosion bidirectional compensator, belongs to the technical field of heat distribution pipeline compensation device.
Background technique
Heat distribution pipeline, because the medium of transmission has very large temperature variation, will inevitably cause expanding with heat and contract with cold of pipeline.Conventionally, be all provided with pipe line compensating device to absorb or compensation pipe deforming in heat distribution pipeline, conventional compensator has spherical compensator, corrugated expansion joint, sleeve expansion joint and whirl compensator.Corrugated expansion joint is little with its volume, pliability good, installation and transportation are convenient, and day by day becomes indispensable important pipe fitting in heating power channelling.Although, existing bellows has withstand voltage, heat-resisting and certain antiseptic property, and still, for the long-term erosion of outdoor rainwater, trench humid air and underground humble and shabby water, its antiseptic power is nowhere near, the performance and used life that has had a strong impact on bellows, has increased construction cost.Therefore, should provide a kind of new technological scheme to address the above problem.
Summary of the invention
The purpose of this utility model is: for above-mentioned deficiency, provide a kind of rational in infrastructure, favorable anti-corrosion effect, direct buried anticorrosion bidirectional compensator that user cost is low.
For achieving the above object, the technical solution adopted in the utility model is: direct buried anticorrosion bidirectional compensator, comprise bellows, pipe nipple, fixedly ring flat-plate, pull bar, be installed on the guide flange on bellows and be installed on the hold-down ring of corrugated tube end and compress filler, described bellows two ends connect respectively at described pipe nipple, described bellows interior is provided with honeycomb duct, the outside of described bellows is provided with oversheath, and the surface of described bellows is provided with one deck anticorrosive coat.
Related content in technique scheme is explained as follows:
In such scheme, anticorrosive coat is polytetrafluoroethylene floor.
In such scheme, between described fixedly ring flat-plate and hold-down ring, be provided with back-up ring.
In such scheme, the joint of described bellows and pipe nipple is provided with gasket ring.
Because technique scheme is used, the utility model compared with prior art has following advantages:
Because the utility model is sprayed with one deck anticorrosive coat on the surface of bellows, described anticorrosive coat is polytetrafluoroethylene floor, and erosion that can resistance to various concentration acid-alkali salts extends working life of compensator, and reduction is produced into.
Because the utility model is fixedly provided with back-up ring between ring flat-plate and hold-down ring, the joint of bellows and pipe nipple is provided with gasket ring, and such structural design makes that compensator structure is compact, work is more reliable.
Accompanying drawing explanation
Accompanying drawing 1 is the utility model example structure schematic diagram.
In above accompanying drawing: 1, bellows; 2, pipe nipple; 3, fixing ring flat-plate; 4, pull bar; 5, guide flange; 6, hold-down ring; 7, compress filler; 8, honeycomb duct; 9, oversheath; 10, anticorrosive coat; 11, back-up ring; 12, gasket ring.
Embodiment
Below in conjunction with drawings and Examples, the utility model is further described:
Embodiment one:
Shown in accompanying drawing 1, the utility model direct buried anticorrosion bidirectional compensator, comprise bellows 1, pipe nipple 2, fixedly ring flat-plate 3, pull bar 4, be installed on the guide flange 5 on bellows 1 and be installed on the hold-down ring 6 of bellows 1 end and compress filler 7, fixedly between ring flat-plate 3 and hold-down ring 6, be provided with back-up ring 11, bellows 1 two ends connect respectively at described pipe nipple 2, bellows 1 is provided with gasket ring 12 with the joint of pipe nipple 2, bellows 1 inside is provided with honeycomb duct 8, the outside of bellows 1 is provided with oversheath 9, the surface of bellows 1 is provided with one deck anticorrosive coat 10, anticorrosive coat 10 is polytetrafluoroethylene floor.Because the utility model is sprayed with one deck anticorrosive coat 10 on the surface of bellows 1, the erosion that they can resistance to various concentration acid-alkali salts, can extend working life of compensator, reduces production costs.Because the utility model is fixedly provided with back-up ring 11 between ring flat-plate 3 and hold-down ring 6, bellows 1 is provided with gasket ring 12 with the joint of pipe nipple 2, and such structural design makes that compensator structure is compact, work is more reliable.
Above-described embodiment is only explanation technical conceive of the present utility model and feature, and its object is to allow person skilled in the art can understand content of the present utility model and implement according to this, can not limit protection domain of the present utility model with this.All equivalences of doing according to the utility model Spirit Essence change or modify, within all should being encompassed in protection domain of the present utility model.
