Abstract
The utility model discloses a kind of PP RT steady-state composite tubes, including PP RT internal layers, PP RT outer layers, aluminum tube layer, there is the first insulating layer the aluminum tube layer inner surface is axially disposed, there is the second insulating layer the aluminum tube layer outer surface is axially disposed, bonded between first insulating layer, the second insulating layer and aluminum tube layer by concavo-convex alternate adhesive；There are at least two S-shaped flow deflectors the inner surface of the internal layer is axially disposed, the first corrosion-resistant coating is provided with the outside of the flow deflector.It is provided with aluminum tube layer in the middle part of the utility model and adds insulating layer, enhances heat insulation effect more than the stability of pipe fitting, add flow deflector so that flow velocity is more uniform.
Description
Technical field
Pipe fitting technical field is the utility model is related to, relates generally to a kind of PP-RT steady-state composite tubes.
Background technology
PE-RT is more soft, and heat conductivility is preferable, its thermal conductivity factor is twice of PP-R, PP-B tubing, the resistance to height of PE-RT
Temperature can reach 90 DEG C, be widely used in floor heating.But layering is easily produced with other materials compound tense, when inside pipe fitting leads to
When entering to have liquid, time slack is anxious during flow velocity, and thermal loss is larger, or even can cause tube burst because impact force is excessive.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of uniform, corrosion resistant with heat insulation effect, flow velocity
PP-RT steady-state composite tubes.
Technical problem to be solved in the utility model can be adopted the following technical scheme that to realize：
A kind of PP-RT steady-state composite tubes, it is characterised in that including PP-RT internal layers, PP-RT outer layers, be arranged on the internal layer
Aluminum tube layer between outer layer, has the first insulating layer the aluminum tube layer inner surface is axially disposed, first insulating layer with
Bonded between aluminum tube layer by concavo-convex alternate adhesive, have the second insulation the aluminum tube layer outer surface is axially disposed
Layer, is bonded between second insulating layer and aluminum tube layer by concavo-convex alternate adhesive；In the inner surface of the internal layer
It is axially disposed to have at least two S-shaped flow deflectors, the first corrosion-resistant coating is provided with the outside of the flow deflector.
In a preferred embodiment of the utility model, first insulating layer is fabricated using rock wool fibers, institute
The second insulating layer is stated to be made of expanded material.
The beneficial effects of the utility model are：A kind of PP-RT steady-state composite tubes, middle part are provided with aluminum tube layer and add insulation
Layer, enhances heat insulation effect more than the stability of pipe fitting, adds flow deflector so that flow velocity is more uniform；Set in water conservancy diversion plate inner surface
Corrosion-resistant coating is equipped with, prevents the liquid corrosion flow deflector in pipe gets rusty from influencing water quality.
Brief description of the drawings
Fig. 1 is a kind of structure diagram of PP-RT steady-state composite tubes of the utility model.
Embodiment
In order to make the technical means, creative features, achievable purpose and effectiveness that the utility model is realized easy to understand, under
Face combines and is specifically illustrating, and the utility model is expanded on further.
Referring to Fig. 1, what is provided in figure is a kind of PP-RT steady-state composite tubes, including PP-RT internal layers 100, PP-RT outer layers
200th, the aluminum tube layer 300 being arranged between internal layer 100 and outer layer 200, has the first guarantor 300 inner surface of aluminum tube layer is axially disposed
Warm layer 410, is bonded between the first insulating layer 410 and aluminum tube layer 300 by concavo-convex alternate adhesive, in aluminum tube layer 300
Outer surface is axially disposed the second insulating layer 420, passes through concavo-convex alternate glue between the second insulating layer 420 and aluminum tube layer 300
Stick is bonded.First insulating layer 410 is fabricated using rock wool fibers, and rock wool fibers cause the insulation of steady-state composite tube to imitate
Fruit is more preferable, more energy saving；Second insulating layer 420 is made of expanded material, can effectively reduce thermal loss.
There are at least two S-shaped flow deflectors 110 the inner surface of internal layer 100 is axially disposed, the cross section of flow deflector 110 is
It is semicircle.The first corrosion-resistant coating 111 is provided with the outside of flow deflector 110, the first corrosion-resistant coating 111 is glass layer, is risen
To corrosion-resistant impact-resistant effect.
Be provided with ASA material layers 500 in the inner side of internal layer 100, ASA is also known as modified resin, modified resin be it is a kind of by
Acrylonitrile, styrene, acrylic rubber composition ter-polymers, belong to Resin Used As Impact Modifier, have good mechanical-physical
Can, there is good weatherability, uvioresistant, anti-aging property.
Flame retardant insulation 600, separation layer 700 are disposed between the second insulating layer 420 and outer layer 200, it is fire-retardant exhausted
Edge layer 600 is made of pvc material, pipe fitting good flame resistance made of polyvinyl chloride, and electrical insulating property is strong, acid-fast alkali-proof；Every
Absciss layer 700 is Amino Polyester material, can completely cut off the temperature in the external world, prevent from impacting pipe fitting.
The direction axially outside of outer layer 200 is provided with some solar panels 800, the sun on daytime can be absorbed and shone
The radiance penetrated.The second corrosion-resistant coating 810 is provided with the outside of solar panel 800, the second 810 layers of anticorrosion uses epoxy
Powder is made.
The advantages of basic principle, main feature and the utility model of the utility model has been shown and described above.One's own profession
The technical staff of industry is it should be appreciated that the present utility model is not limited to the above embodiments, described in above embodiments and description
Simply illustrate the utility model principle, on the premise of not departing from the spirit and scope of the utility model the utility model can also
