Description
[technical field]
The utility model relates to solar water heater field, particularly a kind of rise thermal insulation delivery pipe for solar water heater.
[background technique]
Along with the development of science and technology, environment and resources problem has been the object of global concern, and due to the immoderate exploitation of the mankind, a lot of non-renewable resources are soon exhausted, and people must find new resource to replace, so solar energy becomes the research and development focus of people.Now, solar water heater comes into huge numbers of families, and the supply channel of solar water heater often needs to use attemperater to carry out delivery.At present, insulation pipe is on the market of a great variety, but can not well solve simultaneously heat insulating ability not good, in direct sunlight easily aging, for problems such as the tolerance of the extreme climate such as high temperature or low temperature are not enough, and usually there are quality problems in existing tubing, make troubles to user in installation and using process.
[model utility content]
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, provides a kind of rise thermal insulation delivery pipe for solar water heater, and it is intended to solve the technical problem that rise thermal insulation delivery pipe heat insulating ability of the prior art is poor, weatherability is not high, working life is short.
For achieving the above object, the utility model proposes a kind of rise thermal insulation delivery pipe for solar water heater, described rise thermal insulation delivery pipe is three-decker, by polyolefin pipe, foaming tube and protecting tube composition, described polyolefin pipe, foaming layer and polyethylene layer are plastic tube, described polyolefin pipe is located at the inside of foaming tube, described foaming tube is located at the inside of protecting tube, described polyolefin pipe, foaming tube and protecting tube are extruded by co-extrusion machine and one-body molded, described protecting tube is fixedly connected with foaming tube, the thickness of described polyolefin pipe accounts for 40% ~ 30% of total rise thermal insulation delivery pipe caliber, the thickness of described foaming tube accounts for 40% ~ 55%, the thickness of described protecting tube accounts for 5% ~ 10%.
As preferably, described protecting tube is UV resistance spool.
As preferably, it is one or two at the radical of the polyolefin pipe of described protecting tube inside.
The beneficial effects of the utility model: compared with prior art, a kind of rise thermal insulation delivery pipe for solar water heater that the utility model provides, rational in infrastructure, adopt plastic co-extrusion machine one-body molded, greatly reduce the cost of production of rise thermal insulation delivery pipe, and adopt triple heatproof insulating plastic pipe tubular construction, the heat of inner hot water is made to be not easy to run off, external environment condition is not easy to carry out heat exchange with rise thermal insulation delivery pipe, improve thermal insulation property and the weather resistance of rise thermal insulation delivery pipe, thus solar water heater can be used at low ambient temperatures, simultaneously, adopt the high polyethylene of stability as the tubing of outer tube, rise thermal insulation delivery pipe is made to be laid on sewage, the environment of ponding, the using effect of further raising solar water heater.
Feature of the present utility model and advantage will be described in detail by reference to the accompanying drawings by embodiment.
[accompanying drawing explanation]
Fig. 1 is the structural representation of the utility model embodiment.
[embodiment]
For making the purpose of this utility model, technological scheme and advantage clearly understand, below by accompanying drawing and embodiment, the utility model is further elaborated.But should be appreciated that, specific embodiment described herein, only in order to explain the utility model, is not limited to scope of the present utility model.In addition, in the following description, the description to known features and technology is eliminated, to avoid unnecessarily obscuring concept of the present utility model.
Consult Fig. 1, the utility model embodiment provides a kind of rise thermal insulation delivery pipe for solar water heater, rise thermal insulation delivery pipe is three-decker, be made up of polyolefin pipe 1, foaming tube 2 and protecting tube 3, polyolefin pipe 1, foaming layer and polyethylene layer are plastic tube, polyolefin pipe 1 is located at the inside of foaming tube 2, foaming tube 2 is located at the inside of protecting tube 3, polyolefin pipe 1 and foaming tube 2 are extruded by co-extrusion machine and one-body molded, also be provided with to projecting inward projection in protecting tube 3 inside, projection is wavy, and the outer surface of projection contacts with the outer surface of foaming tube 2.
In the utility model embodiment, innermost layer is in for carrying the polyolefin pipe 1 of hot water, its tubing adopts the heat-resisting polyolefine materials such as polyethylene (PE-RT), polypropylene (PP-R), crosslinked polyethylene (PE-X) or polybutylene (PB) to make, and makes the working life of polyolefin pipe 1 higher; The foaming tube 2 leaked for preventing the heat of hot water mediates layer, and its tubing adopts PVC＝polyvinyl chloride (PVC) foam material or polyurethane foam material to make, and further reduces the loss of heat; Protecting tube 3 for isolating exterior environment is in outermost surface, its tubing adopts PVC＝polyvinyl chloride (PVC) or polyethylene (PE) material to make, not only make rise thermal insulation delivery pipe toughness and impact resistance improve, and can also thus improve the weatherability of rise thermal insulation delivery pipe under different external environment conditions.
As a kind of mode of execution of the utility model embodiment, protecting tube 3 is fixedly connected with foaming layer by extruder, and the outer surface of projection and the outer surface of foaming tube 2 extrude mutually.Now, polyolefin pipe 1, foaming tube 2 and protecting tube 3 are all structure as a whole, and fix without the need to cohesive material compound, not only make the cost of production of rise thermal insulation delivery pipe reduce, but also assembling of person easy to use, improve the using effect of solar water heater.
