Abstract

The utility model relates to a heat insulation material, particularly a heat insulation material which is provided with different thickness according to different heat radiating conditions. A heat insulation structure is composed of at least an inner layer and an outer layer according to the technical proposal provided by the utility model, and the thickness of the upper top of the outer layer is larger than the thickness of the lower bottom of the outer layer. The heat insulation structure is in a tubular shape and is spliced by an inner lower tile block, an outer lower tile blocks, an inner upper tile block and an outer upper tile block, wherein, the inner wall of the cross section of the outer upper tile block is approximately in a round shape, and the outer wall of the cross section of the outer upper tile block is approximately in an ellipse shape. The thickness of the outer upper tile block gradually becomes thin from the central part to the edges of both sides, and finally, the thickness of the outer upper tile block is approximately the same with the thickness of the outer lower tile block. Due to the fact that the top part of the heat insulation material is coated with a composite layer, therefore, the heat insulation effect and the intensity of the heat insulation material can be improved.

Description

The insulating structure of top thickening

Technical field

The utility model relates to thermal insulating material, and is specifically a kind of according to the different thermal-protective materials that different-thickness is set of heat radiation situation.

Background technique

In the heat supply network heat insulating work, used insulating structure is generally the essentially identical thermal-protective material of pipeline outer wall applied thickness, sees Fig. 2, and this insulating structure and the loss of horizontal pipe preserving heat and radiating heat are incompatible along outer protective layer uneven heat dissipation situation.Because the open nothing of upper top of horizontal pipe is blocked, air-flow is unimpeded, and wind speed is than pipeline lower bottom part height, and the heat waste that causes upper top is greater than lower semi-circle; Secondly, hot-fluid air ratio heavy and light in the insulating structure accumulates in the upper top of insulating structure upper semi-circle, the surface temperature that makes the upper semi-circle tile fragment is than lower semi-circle height, the surface temperature of upper semi-circle increases, and also big with regard to change to the temperature difference of atmosphere heat radiation, the heat waste that causes upper top equally is greater than lower semi-circle.

In the prior art, in order to reduce the thermal loss of upper semi-circle, in the upper semi-circle scope, add usually and apply 30～50 millimeters soft thermal insulating material 5, see Fig. 3, in use, the thermal insulating material that lays by this way comes off easily, and overlapping the slot is arranged, in order to prevent that soft thermal insulating material from gliding, need utilize bitch 6 fixing, make complex structure, bitch 6 is metalworks, there is stealthy heat bridge, adds lap gap, badly influence the effect of heat insulation of pipeline.

Summary of the invention

The utility model purpose is the insulating structure of design a kind of top thickening, is coated with composite bed owing to this upper top at thermal-protective material divides, thereby can improves the effect of heat insulation and the intensity of thermal-protective material.

According to design proposal provided by the utility model, insulating structure two-layerly is made of inside and outside at least, and the thickness of outer upper top is greater than the thickness of outer lower bottom part.

Insulating structure is put together by inside and outside tile fragment down and the inside and outside tile fragment of going up in a tubular form, and its transverse section inner wall shape that goes up tile fragment at home and abroad is approximate rounded, goes up the transverse section outer wall shape approximation ovalize of tile fragment outward.To both sides of the edge attenuation gradually, the thickness of tile fragment is approximate identical down at last with outward from the middle part for the thickness of outer upward tile fragment.

Interior tile fragment down and the interior tile fragment of going up are approximately uniform semicircle respectively, and both lump together and constitute a tubulose integral body.Inside and outside down tile fragment with inside and outside on tile fragment contact the wedge-shaped impression that the end face setting is convenient to be bonded with each other.The upper top thickness of insulating structure is bigger 30～60 millimeters than lower bottom part thickness.

The utility model has the advantages that: 1,, take to thicken the upper top insulation layer thickness, improve the heat insulation effect of upper top, to reduce the radiation loss of upper top at the horizontal pipe upper top characteristics bigger than lower bottom part radiation loss; 2, at the following tile fragment radiation loss characteristics lower than last tile fragment, reduce the thickness of tile fragment down, the part thermal insulating material that reduces is added on the tile fragment, both saved the heat insulating work investment, improved heat insulation effect again.3, upper top and the upper semi-circle tile fragment after the thickening is designed to one, and integral manufacturing is half elliptic, do not have the lap gap after lid is applied in thickening, and the hot-fluid heat waste is little.

Embodiment

As shown in the figure: insulating structure two-layerly is made of inside and outside at least, and the thickness of outer upper top is greater than the thickness of outer lower bottom part.

Insulating structure is put together by inside and outside tile fragment 1,3 down and the inside and outside tile fragment 2,4 of going up in a tubular form, and its transverse section inner wall shape that goes up tile fragment 4 at home and abroad is approximate rounded, goes up the transverse section outer wall shape approximation ovalize of tile fragment 4 outward.

To both sides of the edge attenuation gradually, the thickness of tile fragment 3 is approximate identical down at last with outward, so that the shape of whole shell is seamlessly transitted on the whole from the middle part for the thickness of outer upward tile fragment 4.

Interior tile fragment 1 down is approximately uniform semicircle respectively with the interior tile fragment 4 of going up, and both lump together and constitute a tubulose integral body.This structure is more identical with actual conveyance conduit, helps improving heat insulation effect and installation and construction.

Inside and outside down tile fragment 1,3 with inside and outside on tile fragment 2,4 contact the wedge-shaped impression that the end face setting is convenient to be bonded with each other, to increase its adhesive strength, improve its heat-shielding performance.The upper top thickness of insulating structure is bigger 30～60 millimeters than lower bottom part thickness, and this thickness can be saved material as far as possible when guaranteeing certain heat insulation effect.
