Abstract
The utility model relates to a tube special for solar energy. The tube comprises an inner tube and an outer tube, wherein the inner tube is a white inner tube; the outer tube is a black outer tube; the inner tube is positioned in the outer tube and fixedly molded in a double-layer co-extrusion mode; and the inner tube and the outer tube are made of II-type polyethylene of raised temperature resistance (PE-RT) raw materials. The utility model has the advantages that the tube is formed by double-layer co-extrusion of the II-type PE-RT raw materials, can be effectively prevented from being faded and aged in long-time illumination, is high in ultraviolet resistance, protects a pipeline, greatly prolongs the service life, is not influenced by frequent cold heat alternation, meets requirements on high water temperature of a solar water heating system, is not cracked by frost in winter, can keep flexible at low temperature of minus 40 DEG C, and is stable in performance; and the sanitary performance of the tube can accord with the national drinking water standard, and hot water in the tube can be directly drunk.
Description
Technical field
The utility model relates to solar pipe, mainly is a kind of solar energy dedicated pipe that is mainly used on the solar water heater.
Background technology
Used solar pipe on the prior solar water heater, it is permanent that the time is used, and it is aging to occur fading; Anti-uv-ray is not strong yet, as is used under the extreme cold, and the existing pliability of managing very much is not good; Be exposed to the sun through high temperature through extreme cold, service life is shorter again, and performance is also extremely unstable.
Summary of the invention
The purpose of the utility model is to overcome the deficiency of above-mentioned existence, can effectively prevent to fade aging and provide a kind of, and anti-uv-ray is strong, protection pipeline, the solar energy dedicated pipe that increases the service life greatly.
The purpose of the utility model is accomplished through following technical scheme, and it comprises interior pipe, outer tube, and described interior pipe is the interior pipe of white, and outer tube is the outer tube of black, manage in this to be positioned at outer tube, and through the fixedly moulding of double-layer coextrusion mode.
As preferably, described in pipe, outer tube adopt II type PE-RT raw material to be made.
The beneficial effect of the utility model is: adopt II type PE-RT raw material to be made through double-layer coextrusion, it is aging under long-term illumination, can effectively to prevent to fade, and anti-uv-ray is strong, and the protection pipeline increases the service life greatly; Not influenced by frequent colding and heat succeed each other; Be adapted to water temperature higher requirement in the solar water heating system; Not bursting by freezing in winter even under-40 ℃ low temperature, still keeps good flexible; Stable performance, sanitation performance reaches national drinking water standard, and hot water can directly be drunk in the pipe.
Description of drawings
Fig. 1 is the monnolithic case structural representation of the utility model.
Fig. 2 is the cross-sectional view of A-A among Fig. 1.
Fig. 3 is the utility model perspective view.
Label in the accompanying drawing is respectively: 1, interior pipe, 2, outer tube.
The specific embodiment
To combine accompanying drawing that the utility model is done detailed introduction below: like accompanying drawing 1,2, shown in 3; Pipe 1, outer tube 2 in the utility model comprises, the interior pipe that described interior pipe 1 is a white, outer tube 2 is the outer tube of black; Should be positioned at outer tube 2 by interior pipe 1, and through the fixedly moulding of double-layer coextrusion mode.Pipe 1, outer tube 2 adopt II type PE-RT raw material to be made in described.
When being connected, adopt by the pipe fitting of this solar energy dedicated pipe on external device the hot melt spigot-and-socket connected mode fixing.
The utility model is applicable to all kinds of hot-water heating systems, comprises arrangement for quickly heating water and mixing memory, can be connected with all kinds of hot water facilities and complete connecting tube is provided, and like gas heater, electric heater, solar water heater, hot-water boiler etc.
Except that the foregoing description, all employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop on the protection domain of the utility model requirement.
