Abstract
The invention relates to a heat insulating rainhat which has a waterproof effect for an access elbow of a direct buried tube of a heat supply network. The heat insulating rainhat comprises a rain baffle which is divided into two semi-rain baffles. Each semi-rain baffle is fixed on the external wall of a semi-clamp. A hard heat insulating layer and a soft heat insulating layer are orderly arranged on the internal wall of each semi-clamp. The two semi-clamps are connected as a clamp through a fastener. According to the heat insulating rainhat provided by the invention, an insulating layer is arranged between the rain baffle and a core tube so as to prevent heat from being diffused from the rain baffle. The soft insulating layer is arranged in the hard insulating layer, so that the hard heat insulating layer is combined with the core tube compactly, the vibration between the clamp and the core tube is reduced and the temperature resisting performance is improved. The heat insulating rainhat is of a clamp structure so that the heat insulating rainhat is convenient to install.
Description
Technical field
The present invention relates to the annex of heat pipeline, specifically a kind of thermal insulation waterproof cap that plays waterproof action for heat supply network direct buried pipe discrepancy ground elbow.
Background technique
At present, steel sleeve steel directly buried type prefabricated thermal insulation steam line uses more and more generally in heat-net-pipeline.Steel sleeve steel directly buried type prefabricated thermal insulation steam line is made up of core pipe and sleeve pipe, in order to cut off the heat bridge between core pipe and sleeve pipe, each producer has also adopted the measures such as heat-insulated support to cut off heat bridge one after another, but as the vitals rainhat that plays waterproof action of direct buried pipe discrepancy ground elbow, but never pay attention to.
In prior art, rainhat, generally by unit in charge of construction's field fabrication, has two kinds of structures: the one, circular arc steel plate is directly welded on core pipe.The rainhat of this structure, heat can distribute in a large number along with steel plate; The 2nd, steel plate is opened to a slightly larger hole, be enclosed within outside core pipe, be directly placed on outer sleeve.The rainhat of this structure, because core pipe will move along with thermal potential, once displacement is larger, rainwater may pour in down a chimney into direct buried pipe from the hole of opening, the impact causing and loss are just inestimable.
Summary of the invention
The present invention is directed to the problems referred to above, a kind of thermal insulation waterproof cap is provided, this rainhat heat waste is little, and water-proof performance is good.
According to technological scheme of the present invention: a kind of thermal insulation waterproof cap, comprise weather shield, described weather shield is divided into two and half weather shields, every described half weather shield is fixed on the outer wall of half clamp, on the inwall of each described half clamp, be disposed with hard heat-insulating layer and soft thermal-protective coating, two described half clamps connect into a clamp by fastening piece.
The material of described hard heat-insulating layer is heat insulating casting material.
The thermal conductivity of described heat insulating casting material is 0.2 W/ (mK) in the time of 250 DEG C.
The material of described soft thermal-protective coating is alumina silicate needle punched blanket.
Described weather shield is conical.
Technique effect of the present invention is: the present invention is provided with thermal-protective coating between weather shield and core pipe, can prevent that heat from distributing from weather shield; It is tightr that soft thermal-protective coating in hard heat-insulating layer closes hard heat-insulating layer and core duct ligation, reduced the vibration between clamp and core pipe, improved heat resistance; Clipping type structure, easy for installation.
Brief description of the drawings
Fig. 1 is structural representation of the present invention.
Fig. 2 is the plan view of Fig. 1.
Embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is further described.
In Fig. 1, Fig. 2, comprise core pipe 1, clamp 2, weather shield 3, sleeve pipe 4, hard heat-insulating layer 5, soft thermal-protective coating 6, half weather shield 7, half clamp 8 etc.
As shown in Figure 1 and Figure 2, the present invention is a kind of thermal insulation waterproof cap, comprises weather shield 3 and clamp 2, and weather shield 3 is welded on the outer wall of clamp 2.
Weather shield 3 and clamp 2 are divided into two halves, connect into an entirety by fastening piece.Weather shield 3 is divided into two and half weather shields 7, and clamp 2 is divided into two and half clamps 8.Every half weather shield 7 is fixed on the outer wall of half clamp 8, is disposed with hard heat-insulating layer 5 and soft thermal-protective coating 6 on the inwall of each half clamp 8.
The material of hard heat-insulating layer 5 is heat insulating casting material, is cast in half clamp 8 and is formed by heat insulating casting material.The thermal conductivity of heat insulating casting material is 0.2 W/mK in the time of 250 DEG C.
The material of soft thermal-protective coating 6 is alumina silicate needle punched blanket.
It is conical that weather shield 3 is preferably, can make rainwater take advantage of a situation and under, play guide functions.
The present invention is arranged on direct buried pipe and comes in and goes out on ground elbow, is positioned on the core pipe of sleeve pipe 4 tops.When installation, directly two and half clamps 8 are enclosed within outside core pipe 1, then with fastening piece, two and half clamps 8 are fixed, hard heat-insulating layer 5 in clamp 2 forms heat insulation tile fragment, two and half weather shields 7 are combined into a weather shield 3, block above sleeve pipe 4 opening ends, play rainproof effect.After installing, two and half weather shields 7 can be welded together.
The present invention is fixed on weather shield 3 in clamp 2, is provided with hard heat-insulating layer 5 in clamp 2, between weather shield 3 and core pipe 1, is separated by hard heat-insulating layer 5, prevents that heat from distributing from weather shield 3; Soft thermal-protective coating 6 in hard heat-insulating layer 5 makes hard heat-insulating layer 5 tightr with 1 combination of core pipe, has reduced the vibration between clamp 2 and core pipe 1, has improved heat resistance; Clipping type structure, easy for installation.
