Description
Technical field
The utility model relates to hot water heat insulating pipe construction applications, the insulating tube of connection and hot water outlet between a kind of especially solar energy hot water tank.
Background technology
In winter, because the heat loss of water pipe even reduces by 10 DEG C, greatly waste the energy.In order to reduce from boiler next to the heat loss of the hot-water line of user, tube surface heat insulating cloth wraps up by people, and the defect of this method is: install cumbersome, interim coated heat insulating cloth; Because manually coated making has larger space between heat-insulation layer and pipeline outer wall, so the effect of insulation is not ideal enough, larger energy is still had to leak; Leak owing to there is energy, so safe not, particularly when heat insulating cloth breakage, be easy to the security incidents such as scald or frostbite occur and the service life shortening insulating tube, and the heat insulating cloth being exposed to outside is also difficult to stand low temperature and rainy invasion.
Solar heat reflection reticulate pattern insulating tube disclosed in Chinese patent 201320479875.5, it is bimetallic tube, and innermost layer is interior pipe, and outer wall of inner tube is coated with one deck heat-reflecting layer, wraps up reticulated duct outside heat-reflecting layer.But this structure is due near apart between inner and outer pipes, and heat insulation effect is in long-time heat preservation situation, and successful is not enough; Particularly under high-temperature, long-time logical enthusiasm condition, insulation seems not enough.
Utility model content
Goal of the invention of the present utility model is: for above-mentioned technical problem, provides a kind of insulating tube, meets the situation needs that high temperature leads to heat, long-time logical heat.
Technical solutions of the utility model are: a kind of insulating tube, comprise outer tube and interior pipe, described interior pipe is fixed on outer tube hub by fixed support, polyurethane insulation coating is formed by polyurethane foam between described outer tube and interior pipe, described inner tube outer surface is provided with solar energy heat absorbing coating, and described outer pipe internal surface is provided with infrared reflection coating.
Here it is to be understood that polyurethane foam forms polyurethane insulation coating have excellent heat insulation effect, form wider heat-insulation layer simultaneously, the needs of long-time logical heat insulation can be met.On the basis of the above, also add solar energy heat absorbing coating, solar energy heat absorbing coating better can absorb infrared ray, thus form a heat absorbing ring or perhaps heat build-up layer at inner tube outer surface, due to interior pipe direct contact heat water or hot solution, cause its inner tube outer surface still to have higher temperature, and the heat that solar energy heat absorbing coating can reduce interior pipe overflow.And intermediate urethane heat-insulation layer reduces heat diffusion further, outer pipe internal surface is provided with infrared reflection coating to the infrared reflection of polyurethane insulation coating, can reduce polyurethane insulation coating heat diffusion.Multi-layer heat preserving structure is set like this, gradually reduces heat in interior pipe and, to external diffusion, reach the effect of insulation.Compared to existing technology, heat insulation effect is more obvious, meets the situation needs that high temperature leads to heat, long-time logical heat.
Preferably, also ceramic coating is provided with between described infrared reflection coating and interior pipe.Ceramic coating has the large feature of specific heat capacity, has good heat insulation effect to this its.
Preferably, described polyurethane insulation coating is provided with some through holes, described through hole and interior tube hub axis being parallel.Through hole is set and can increases interlayer, optimize polyurethane heat-insulation Rotating fields further.
Preferably, described interior pipe is metal bellows.Here the metal bellows provided is for preferred embodiment.
The utility model beneficial effect is:
1, the utility model is made up of outer tube, infrared reflection coating, polyurethane insulation coating, solar energy heat absorbing coating and interior pipe, during use, hot water is at interior Bottomhole pressure, solar energy heat absorbing coating forms heat absorbing ring, pipe externally heat radiation in reducing, play thermal insulation function, polyurethane insulation coating plays the effect of insulation further, infrared reflection coating to the infrared reflection of polyurethane insulation coating, can reduce polyurethane insulation coating heat diffusion; The energy of the hot water like this in pipe not easily leaks; Out can not form the security incident of scalding (or frostbite) by Quick diffusing, the situation needs that high temperature leads to heat, long-time logical heat can be met.
2, the utility model is rational in infrastructure, and heat insulation effect is obvious, and firm in structure, reliable in quality, also easily carrying and installation.
3, the utility model utilize in medium (as water, gas etc.) in pipe in course of conveying, only have very little energy loss, thus saved the energy, be conducive to environmental protection, and made insulating tube form a shaping product, be easy to be extended and applied.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation;
Wherein, pipe, 3-fixed support, 4-polyurethane insulation coating, 5-through hole, 6-solar energy heat absorbing coating, 7-infrared reflection coating in 1-outer tube, 2-.
Detailed description of the invention
The utility model discloses a kind of insulating tube, comprise outer tube 1 and interior pipe 2, described interior pipe 2 is fixed on outer tube 1 center by fixed support 3, polyurethane insulation coating 4 is formed by polyurethane foam between described outer tube 1 and interior pipe 2, described interior pipe 2 outer surface is provided with solar energy heat absorbing coating 6, and described outer tube 1 inner surface is provided with infrared reflection coating 7.
The utility model is followed successively by outer tube 1, infrared reflection coating 7, polyurethane insulation coating 4, solar energy heat absorbing coating 6 and interior pipe 2 from outside to inside.Solar energy heat absorbing coating 6, solar energy heat absorbing coating 6 better can absorb infrared ray, thus form a heat absorbing ring or perhaps heat build-up layer at interior pipe 2 outer surface, due to interior pipe 2 direct contact heat water or hot solution, cause pipe 2 outer surface in it still to have higher temperature, and the heat that solar energy heat absorbing coating 6 can reduce interior pipe 2 overflow.And intermediate urethane heat-insulation layer 4 reduces heat diffusion further, outer tube 1 inner surface is provided with infrared reflection coating 7 to the infrared reflection of polyurethane insulation coating 4, can reduce polyurethane insulation coating 4 heat diffusion.Multi-layer heat preserving structure is set like this, gradually reduces heat in interior pipe 2 and, to external diffusion, reach the effect of insulation.Compared to existing technology, heat insulation effect is more obvious, meets the situation needs that high temperature leads to heat, long-time logical heat.
Implement to be described to the utility model below in conjunction with accompanying drawing.
As shown in Figure 1, a kind of insulating tube, comprises outer tube 1 and interior pipe 2, and its middle external tube 1 is PA tube, and interior pipe 2 is metal bellows.Interior pipe 2 is fixed on outer tube 1 center by fixed support 3, and form polyurethane insulation coating 4 by polyurethane foam between outer tube 1 and interior pipe 2, described interior pipe 2 outer surface is provided with solar energy heat absorbing coating 6, and described outer tube 1 inner surface is provided with infrared reflection coating 7.Also ceramic coating is provided with between described infrared reflection coating 7 and interior pipe 2.Ceramic coating has the large feature of specific heat capacity, has good heat insulation effect to this its.
