Abstract
The utility model discloses a directly-buried heat-preservation corrosion-preventing bidirectional compensator. The directly-buried heat-preservation corrosion-preventing bidirectional compensator is characterized by comprising a corrugated pipe, an end connection pipe, a fixed annular plate, a pulling rod, a guiding flange installed on the corrugated pipe, a pressing ring and a pressing filler, wherein the pressing ring and the pressing filler are installed at the end of the corrugated pipe. Two ends of the corrugated pipe are respectively connected with the end connecting pipe, a guide pipe is arranged inside the corrugated pipe, an outer sheath is arranged outside the corrugated pipe, and a heat-preservation sheath is arranged outside the outer sheath. The directly-buried heat-preservation corrosion-preventing bidirectional compensator has the advantages of being reasonable in structure, good in heat-preservation effect, convenient to install and long in service life.
Description
Technical field
The utility model relates to a kind of direct-buried thermal-insulating 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.Traditional FlexbleJoint is in use normally at the on-the-spot installing insulating paper in the outside of bellows or plastic wrapper, and this mode not only heat insulation effect is bad, and wastes time and energy, and affects working efficiency, increases workman's labor intensity.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, high insulating effect, direct-buried thermal-insulating bidirectional compensator easy for installation.
For achieving the above object, the technical solution adopted in the utility model is:
A kind of direct-buried thermal-insulating 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 outside of described oversheath is provided with heat insulation sheath.
The material of described heat insulation sheath is polyurethane foam.
The joint of described guide flange and bellows is provided with metal retaining ring.
Because technique scheme is used, the utility model compared with prior art has following advantages:
Because the utility model is provided with thermal-insulation coat in the outside of oversheath, the material of thermal-insulation coat is polyurethane foam, make compensator of the present utility model in use, do not need extra installing insulating paper or plastic wrapper at the scene, high insulating effect not only, and time saving and energy saving, working efficiency is high, has reduced workman's labor intensity.
Because the utility model is provided with metal retaining ring in the joint of guide flange and bellows, such structural design has strengthened the intensity of compensator, makes the work of compensator more reliable, long service life.
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, heat insulation sheath; 11, metal retaining 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, guide flange 5 is provided with metal retaining ring 11 with the joint of bellows 1, bellows 1 two ends connect respectively at described pipe nipple 2, bellows 1 inside is provided with honeycomb duct 8, the outside of bellows 1 is provided with oversheath 9, the outside of oversheath 9 is provided with heat insulation sheath 10, and the material of heat insulation sheath 10 is polyurethane foam.Because the utility model is provided with thermal-insulation coat 10 in the outside of oversheath 9, the material of thermal-insulation coat 10 is polyurethane foam, make compensator of the present utility model in use, do not need extra installing insulating paper or plastic wrapper, high insulating effect not only, and time saving and energy saving, working efficiency is high, has reduced workman's labor intensity.Because the utility model is provided with metal retaining ring 10 in the joint of guide flange 5 and bellows 1, such structural design has strengthened the intensity of compensator, makes the work of compensator more reliable, long service life.
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.
