Abstract
The utility model discloses a capillary pipe and belongs to the field of heating pipes of floor heating systems. The capillary pipe is formed by an inner layer, a middle layer and an outer layer and is characterized in that the inner layer is an ethylene-ethenol layer, the middle layer is a heat-resisting polyethylene layer, and the outer layer is a polypropylene (PP-R) layer. By means of the technical scheme, the capillary pipe has the advantages of being corrosion-resistant, heat-resistant, pressure-resistant, capable of guaranteeing stability and comfortableness of floor heating systems and the like.
Description
Technical field
The utility model relates to heating tubing field, particularly a kind of capillary.
Background technology
On September 22nd, 2009, the President Hu Jintao delivers the Leading Speaches that is entitled as " tackling hand in hand the climate change challenge " in the U.N. climate change summit opening ceremony, wherein be exactly to greatly develop green economy, develop actively low-carbon economy and recycling economy are so the capillary heat pump air conditioner system represents the environmental protection and energy saving of HVAC technology trends just.Weather close friend's renewable energy utilization technology.Traditional heating tubing owing to being subject to the situations such as the impact of the elements such as Heat And Water Balance the heating inequality easily occurs, be out of shape and be corroded, has had a strong impact on ground heating system stability and comfortableness in the process that reality is used.
In sum, for the defective of prior art and device, need especially a kind of capillary of anticorrosive, heat-resistant pressure-resistant, to solve above-mentioned problem.
The utility model content
The utility model provides a kind of capillary of anticorrosive, heat-resistant pressure-resistant.
The technical problem that the utility model solves can realize by the following technical solutions:
A kind of capillary is made of internal layer, intermediate layer and skin, it is characterized in that, described internal layer is the ethylene-vinyl alcohol layer, and described intermediate layer is the heat-proof polythene layer, and described skin is the PP-R layer.
Owing to having adopted above-mentioned technical scheme, the utlity model has the characteristics such as anticorrosive, heat-resistant pressure-resistant, guaranteed stability and the comfortableness of geothermal system.
Description of drawings
Fig. 1 is a kind of radial cross-section capillaceous of the utility model.
The specific embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
As shown in Figure 1, a kind of capillary is made of internal layer 13, intermediate layer 12 and outer 11, it is characterized in that, described internal layer 13 is the ethylene-vinyl alcohol layer, and described intermediate layer 12 is the heat-proof polythene layer, and described outer 11 is the PP-R layer.
Because body 10 has used outer PP-R layer 11, has the following advantages: nontoxic, health, the raw molecule of PP-R only has carbon, protium, does not have harmful poisonous element to exist, and health is reliable, not only is used for cold hot water piping, also can be used for the purified water for drinking system; Heat preservation energy-saving, PP-R pipe thermal conductivity factor is 0.21w/mk, only is 1/200 of steel pipe; Heat resistance preferably, 131.5 ℃ of the Vicat softening points of PP-R pipe, maximum operating temperature can reach 95 ℃, can satisfy the instructions for use of hot-water heating system in the code for the design of water supply and sewerage of buildings; Long service life, PP-R pipe, can reach more than 50 years under operating pressure (P.N) the 1.0MPa condition 70 ℃ of operating temperatures service life, and can reach more than 100 years (20 ℃) service life under the normal temperature; Easy for installation, connect reliably, PP-R has good welding performance, and tubing, pipe fitting can adopt hot melt to be connected with electric smelting, and be easy for installation, and the intensity of its connecting portion is greater than the intensity of tubing itself; The material recoverable; The PP-R waste material is recycled in tubing, pipe fitting production after cleaning, fragmentation.The reclaimed materials consumption is no more than total amount 10%, does not affect product quality.
Exactly because above-mentioned advantage has been arranged, this capillary has guaranteed stability and the comfortableness of geothermal system.
Above demonstration and described basic principle of the present utility model and principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; that describes in above-described embodiment and the specification just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
