Abstract
The utility model discloses a kind of interior slip steamy thermal insulated direct-buried pipe, comprise steam tube and heat-preservation cotton, be characterized in that heat-preservation cotton is arranged in the airtight cavity being comprised of outer sleeve, bushing pipe and shrouding; Described bushing pipe and outer sleeve are suit, and its two ends are by shrouding capping, shrouding and outer sleeve with bushing pipe for being fixedly connected with; Suit steam tube in described bushing pipe, steam tube and bushing pipe are for being slidably connected.The utility model compared with prior art has simple in structure, high insulating effect, and easy construction, has effectively avoided heat-preservation cotton felt suffer water soaking and gap in use to widen phenomenon, weakens support heat bridge effect, reduces the loss of heat supply network overall thermal.
Description
Technical field
The utility model relates to pipeline heat-insulating technology field, slip steamy thermal insulated direct-buried pipe in especially a kind of waterproof type.
Background technique
Directly buried installation thermal insulation steam pipeline is divided into outer sliding type and the large class of inner sliding type two because thermal insulating material is different with insulating structure and preparation process, outer sliding type insulating steam pipe is generally all used the fiber thermal insulating materials such as glass wool or alumina silicate felt, and thermal insulating material is attached on core pipe.Because cotton felt class material can not load-bearing, can not keep definite physical dimension, therefore in every thermal insulation pipe, two supports are all set, support is fixed on core pipe, make core pipe can stretch or shrink along conduit axis direction when temperature variation, outer steel pipe is by bracket leg support core pipe, and outer steel pipe is fixed in soil motionless.Because core pipe is subject to thermal stretching, and being provided with two supports, there is faulted joint at pipeline axial in heat-preservation cotton felt, and faulted joint is widened formation heat bridge when core pipe extends.Before pipe network compensator, core pipe is maximum with respect to the displacement amount of outer steel pipe, can reach 100mm to 500mm, is incubated pipe network Local Shape and becomes obvious naked pipe section when serious.And outer sliding type insulation pipe does not have self-sealing function conventionally, thermal insulation layer is easily intake, once soak as the thermal insulating material water inlet of glass wool one class, heat insulation effect obviously worsens.
Model utility content
The purpose of this utility model is a kind of interior slip steamy thermal insulated direct-buried pipe designing for the deficiencies in the prior art, steam tube is sleeved in the insulating structure of water-proof sealing, effectively avoided round water soaking of heat-preservation cotton felt in installation or using process, heat insulation effect is survivable, the physical dimension of thermal insulation layer, shape and position immobilize, gap can not produced and phenomenon is widened in gap, greatly weakened support heat bridge effect, reduce the thermal loss of pipe network, simple in structure, high insulating effect, easy construction.
The purpose of this utility model is achieved in that a kind of interior slip steamy thermal insulated direct-buried pipe, comprises steam tube and heat-preservation cotton, is characterized in that heat-preservation cotton is arranged in the airtight cavity being comprised of outer sleeve, bushing pipe and shrouding; Described bushing pipe and outer sleeve are suit, and its two ends are by shrouding capping, shrouding and outer sleeve with bushing pipe for being fixedly connected with; Suit steam tube in described bushing pipe, steam tube and bushing pipe are for being slidably connected.
The utility model compared with prior art has simple in structure, high insulating effect, easy construction, effectively avoided round water soaking of heat-preservation cotton felt in installation or using process, heat insulation effect is survivable, and the physical dimension of thermal insulation layer, shape and position immobilize, and can not produce gap and phenomenon is widened in gap, greatly weaken support heat bridge effect, reduced the thermal loss of pipe network.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Embodiment
Consult accompanying drawing 1, the utility model is comprised of steam tube 1 and heat-preservation cotton 5, and described heat-preservation cotton 5 is arranged in the airtight cavity being comprised of outer sleeve 4, bushing pipe 2 and shrouding 3; Described bushing pipe 2 is suit with outer sleeve 4, and its two ends are by shrouding 3 cappings, shrouding 3 and outer sleeve 4 with bushing pipe 2 for being fixedly connected with; The interior suit steam tube 1 of described bushing pipe 2, steam tube 1 is with bushing pipe 2 for being slidably connected, and phenomenon is widened in gap and gap that while effectively having avoided moving due to steam tube 1, traction heat-preservation cotton 5 produces.
The utility model is to make like this: first at the additional fitted lining pipe 2 of steam tube 1, bushing pipe 2 is formed by Steel Thin-Wall coiled sheet system, then in bushing pipe 2 outer wrapping heat-preservation cotton 5, the bushing pipe 2 of parcel heat-preservation cotton 5 is sleeved in outer sleeve 4, capping is carried out by shrouding 3 in its two ends, shrouding 3 is welding with outer sleeve 4 and bushing pipe 2, effectively avoided heat-preservation cotton 5 in Tube formation or using process, to suffer underground water immersion and gap to widen the generation of phenomenon, shrouding 3 has not only played the waterproof sealing effect of heat-preservation cotton 5, but also there is enough bearing capacitys, support steam tube 1, make thermal insulation layer keep changeless shape and position, the thermal loss of minimizing system.
More than just the utility model is further described, not in order to limit this patent, all is that the utility model equivalence is implemented, within all should being contained in the claim scope of this patent.
