Abstract
The utility model provides a heat -supply thermal insulation pipe, heat preservation including the hot dip zinc pipe of inlayer, outermost outer pillar and centre, heat insulation layer draws together the connection and is in calcium silicate layer, the connection of hot -galvanize outside of tubes wall are in the rock wool layer of outer pillar inner wall and being located air bed between calcium silicate layer and the rock wool layer, be equipped with a plurality of supports in the air bed in order to guarantee air bed thickness. The cooperation on calcium silicate layer, air bed and rock wool layer is used, greatly reduced the thermal conductivity of heat preservation, obviously improved heat -supply thermal insulation pipe's thermal insulation performance, reduced the heat loss of insulating tube, it is extravagant to have reduced the energy.
Description
Technical field
The utility model relates to a kind of thermal insulation pipe, particularly relates to a kind of heat supply thermal insulation pipe for central heating.
Background technique
Thermal insulation pipe is being commonly called as of insulated piping, is applicable to the various media of conveying within the scope of-50 DEG C ~ 150 DEG C, and it is widely used in the insulation prepressing reserving works of the industries such as central heat supply, the conveying supplying cold-peace deep fat and greenhouse, freezer, colliery, oil, chemical industry.
Existing thermal insulation pipe generally comprises inner hot dip galvanizing pipe, outside outer pillar and the thermal insulation layer between hot dip galvanizing pipe and outer pillar.In prior art, thermal insulation layer is generally polyurethane, also has some to be rock wool.Conventional thermal insulation pipe heat insulation effect is not very desirable, especially when long-distance sand transport, causes thermal loss in thermal insulation pipe excessive, cause the energy to waste in a large number because thermal insulation pipe heat insulation effect is not good.
Summary of the invention
The utility model is for solving the problems of the technologies described above and providing a kind of heat supply thermal insulation pipe.
Technical solution adopted in the utility model is: a kind of heat supply thermal insulation pipe, comprises the thermal insulation layer of the hot dip galvanizing pipe of innermost layer, outermost outer pillar and centre; The air layer that described thermal insulation layer comprises the calcium silicate layer being connected to described hot dip galvanizing pipe outer wall, the rock wool layer being connected to described outer pillar inwall and is located between described calcium silicate layer and rock wool layer; Some supports are provided with to ensure air layer thickness in described air layer.Calcium silicate layer, air layer and rock wool layer with the use of, greatly reduce the thermal conductivity of thermal insulation layer, significantly improve the thermal insulation property of heat supply thermal insulation pipe, reduce the thermal loss of thermal insulation pipe, decrease energy waste.
Rock wool layer is softer, and rock wool layer can be caused to be out of shape if support is directly supported on rock wool layer, rock wool layer thickness and air layer thickness are all difficult to be protected, and therefore as further improving, is provided with supporting layer between described air layer and described rock wool layer.
As preferably, the material of described supporting layer and outer pillar is polyethylene.
If support is directly radially connected to supporting layer by calcium silicate layer, so heat is easier to be delivered to supporting layer by support by calcium silicate layer, so then reduces the effect of air layer.In order to avoid this situation, preferably, described support is the two-dimensional helical plate of rigidity.If heat is radially transmitted by calcium silicate layer, then air layer cannot be avoided; If transmit along two-dimensional helical plate, then bang path is very long, and two ends are point cantact, and the heat shed is little.
In order to strengthen the support strength of two-dimensional helical timbering, as further improvement, described two-dimensional helical plate maximum radius place is provided with outer rim; Be connected to outside described outer rim on described supporting layer; Described two-dimensional helical plate least radius place is provided with interior steel ring; Described interior steel ring inwall is connected on described calcium silicate layer.
The advantage that the utility model has and good effect are: because the utility model adopts as above technological scheme, calcium silicate layer, air layer and rock wool layer with the use of, greatly reduce the thermal conductivity of thermal insulation layer; In preferred version, not only intensity is high for the support of two-dimensional helical tabular, and heat radiation is few.The utility model significantly improves the thermal insulation property of heat supply thermal insulation pipe, reduces the thermal loss of thermal insulation pipe, decreases energy waste.
Except technical problem, the technical characteristics forming technological scheme and the advantage brought by the technical characteristics of these technological schemes that the utility model described above solves, the advantage that the other technologies feature comprised in the other technologies problem that the utility model can solve, technological scheme and these technical characteristicss bring, will be described in further detail hereinafter by reference to the accompanying drawings.
