The purpose of this utility model is achieved through the following technical solutions:
A kind of detachable heat-insulation shell, every pipe joint shell is made up of semicircular two thermal-insulating pipe cases, described each semicircular thermal-insulating pipe case is made up of first layer heat insulation type cotton, second layer heat insulation type cotton, shell fixing frame and high temperature resistant low heat-conducting connecting, described first layer heat insulation type cotton is arranged on the inner side of second layer heat insulation type cotton, between first layer heat insulation type cotton and second layer heat insulation type cotton, in hoop and longitudinal direction staggered floor setting respectively, the outside of second layer heat insulation type cotton is provided with shell fixing frame.Between first layer heat insulation type cotton, second layer heat insulation type cotton and shell fixing frame, be fixed together by high temperature resistant low heat-conducting connecting.
Also comprise the 3rd layer of heat insulation type cotton, described the 3rd layer of heat insulation type cotton is arranged on the outside of second layer heat insulation type cotton, between cotton and the 3rd layer of heat insulation type cotton of first layer heat insulation type cotton, second layer heat insulation type, in hoop and longitudinal direction staggered floor setting respectively, between first layer heat insulation type cotton, second layer heat insulation type cotton, the 3rd layer of heat insulation type cotton and shell fixing frame, be fixed together by high temperature resistant low heat-conducting connecting.
Select the number of plies of heat insulation type cotton according to the difference of pipe insulation thickness and heat-preservation cotton thickness, can be two-layer can be also multilayer.Cotton and the 3rd layer of heat insulation type cotton of described the first heat insulation type cotton, second layer heat insulation type made by felted or blanket shape heat-preservation cotton, according to the difference of pipe insulation thickness and heat-preservation cotton thickness, can select two-layer or multi-layer heat preserving is cotton.
Determine and in above-mentioned thermal-insulating pipe case, add flexible shell according to the extending amount of pipeline, telescopic section is to be made up of the material of utmost point low thermal conductivity, flexible shell is to be made up of inside and outside overlapping two-part, every part is all equivalent to respectively normal insulation thickness, produce while stretching, do not affect heat insulation effect herein.
The beneficial effects of the utility model are: quick and easy for installation, standardized construction, is not easy to come off after installing, high insulating effect, detachably repeatedly.Shell is linked together by high temperature resistant low heat-conducting connecting colligation, without any Bond, with adjacent heat-preservation cotton staggered floor overlap joint, thermal conductivity is low, can integral demounting, there is no the flexible heat radiation gap causing, realize energy-efficiently, reduce construction pollution, also can reduce material cost and construction cost.Press close to pipe surface place temperature the highest, heat-preservation cotton herein arrives working life at first, now only needs to change the internal layer heat insulation type cotton of innermost layer.
