Description

A kind of watt/bubble composite thermal-insulating pipe case
Technical field
The utility model relates to pipeline heat-insulating technology field, the coated bonding micropore calcium watt shape all-in-one-piece watt of especially a kind of hard polyurethane foams /bubble composite thermal-insulating pipe case.
Background technique
Under the overall background of environmental pollution, central heat supply is inevitable trend, following domesticly can build more central heating network, and microporous calcium silicate watt and polyurethane composition are the insulating structures that cost performance is the highest in conventional thermal insulating material, are widely used in industrial steam transmission and distribution network.Industrial steam pipe network has direct-burried and built on stilts two kinds of laying methods, and make somebody a mere figurehead and lay because cost is low, convenient for maintaining, occupies very large proportion in pipeline network construction.Make somebody a mere figurehead and lay steam pipe system at present based on in-site installation, though prefabricated built on stilts steam insulation pipe is introduced to the market, but because long-distance transport cost is high, thermal insulation layer cracky, all seldom prefabricated built on stilts steam insulation pipe is adopted so general, and scene does not possess the operating condition that prefabricated tile-bubble compound insulation structure makes somebody a mere figurehead steam insulation pipe, so seriously constrain the use of thermal insulating material on heat distribution pipe network of microporous calcium silicate watt and polyurethane composition.
Model utility content
The purpose of this utility model is the one watt designed for the deficiencies in the prior art /bubble composite thermal-insulating pipe case, adopt the thermal-insulating pipe case that polyurethane foam coated bonding micropore calcium watt and metal-coating are integrated, realize the field-installed insulation pipe of prefabrication, thermal-insulating pipe case can cut into random lengths, staggered joint erection, make built on stilts steam pipe system in any long distance pipeline section without penetrating circumferential weld, do not ooze rainwater, greatly can save pipe network heat retaining operation man-hour, structure is simple, lightweight, high insulating effect, low cost of manufacture, easy construction, is particluarly suitable for application in the insulation transformation of the empty steam pipe system of coil holder.
The purpose of this utility model is achieved in that a kind of watt /bubble composite thermal-insulating pipe case, be characterized in that this thermal-insulating pipe case is made up of inner thermal insulating layer and external thermal insulation and metal-coating, described inner thermal insulating layer is the single or multiple lift microporous calcium silicate watt thermal-insulating pipe case that the misalignment fissure of displacement is built by laying bricks or stones; Described external thermal insulation is the polyurethane foam be poured between metal-coating and inner thermal insulating layer, polyurethane foam be coated on inner thermal insulating layer outer and bonding with metal-coating for watt /the composite thermal-insulating pipe case of bubble one.
It is simple that the utility model compared with prior art has structure, the advantage of easy construction, realize the field-installed insulation pipe of prefabrication, thermal-insulating pipe case can cut into random lengths, staggered joint erection, makes built on stilts steam pipe system in any long distance pipeline section without penetrating circumferential weld, do not ooze rainwater, high insulating effect, can save pipe network heat retaining operation man-hour greatly, is particluarly suitable for application in the insulation transformation of the empty steam pipe system of coil holder.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation;
Fig. 2 is Fig. 1 left view.
Embodiment
Accompanying drawings 1 ~ accompanying drawing 2, the utility model is made up of with external thermal insulation 2 and metal-coating 1 inner thermal insulating layer 3, and described inner thermal insulating layer 3 is the single or multiple lift microporous calcium silicate watt thermal-insulating pipe case that the misalignment fissure of displacement is built by laying bricks or stones; Described external thermal insulation 2 for being poured in the polyurethane foam between metal-coating 1 and inner thermal insulating layer 3, polyurethane foam be coated on inner thermal insulating layer 3 outer and bonding with metal-coating 1 for watt /the composite thermal-insulating pipe case of bubble one.
The utility model makes like this: metal-coating 1 is rolled by thin-wall metal and the seamless pipe box of entirety, inner thermal insulating layer 3 by single or multiple lift microporous calcium silicate watt build by laying bricks or stones form and watt and watt between the misalignment fissure of displacement, filling polyurethane foam between metal-coating 1 and the inner thermal insulating layer 3 of being built by laying bricks or stones by microporous calcium silicate watt, foaming forms external thermal insulation 2, polyurethane foam is by watt compacting of internal layer microporous calcium silicate and respectively watt bonding with the microporous calcium silicate of metal-coating 1 and inner thermal insulating layer 3, after polyurethane foam solidification, form overall watt-bubble composite thermal-insulating pipe case.
The utility model can cut into random lengths, can staggered joint erection, make built on stilts steam pipe system in any long distance pipeline section without penetrating circumferential weld, do not ooze rainwater, and do not need support of pipelines, pipeline holds up by pipe network concrete buttress or truss outside metal-coating 1, thus without heat bridge effect, high insulating effect, and greatly can save pipe network heat retaining operation man-hour, is particularly useful for built on stiltsly laying steam pipe system.
More than just be further described the utility model, and be not used to limit this patent, all be the utility model equivalence enforcement, within the right that all should be contained in this patent.
