The utility model discloses a kind of low temperature resistant galvanized pipe, including galvanized pipe matrix, plastic tube is arranged with the galvanized pipe matrix, packing layer is provided with the cavity between plastic tube and galvanized pipe, coating steel pipe outer wall, which is provided with the inside of zinc coat, passivation layer, plastic tube, is provided with layer of silica gel.Above-mentioned low temperature resistant galvanized pipe adds the intensity of galvanized pipe, it is not easy to deform by being provided with packing layer in the interior plastic pipe-covered and interlayer cavity body of zinc-plated tube body, and does not influence the use of body, extends service life；And the plastic tube and packing layer being provided with galvanized pipe also increase the corrosion resistance of galvanized pipe, during long-term use, will not because of fluid inside flowing, the galvanized pipe on the outside of corrosion also functions to the effect increased the service life；It is provided at an outer portion with heat-insulation layer so that under conditions of temperature is too low, can also uses；Provided with layer of silica gel is provided with the outside of layer of silica gel and heat-insulation layer on the inside of plastic tube, have the advantages that intensity is high, low temperature resistant, be difficult breach.
Description
Technical field
The utility model is related to the zinc-plated field of steel pipe, especially a kind of low temperature resistant galvanized pipe.
Background technology
Galvanized pipe, also known as coating steel pipe, are divided into two kinds of galvanizing and electrogalvanizing, hot dip galvanizing pipe is to make molten metal and iron-based
Precursor reactant alloy-layer, so that both matrix and coating are combined.Galvanized pipe is internal easily to produce knot after long-term use
Dirt, easily get rusty, inwall it is rough, reduction of service life.
The external such as U.S., Japan and other countries, more than 80% Construction Conveying Water pipe use external galvanized layer internal plastic coating steel pipe.At present,
The requirement of external galvanized layer internal plastic coating steel pipe is also directly clearly write on design by some domestic designing institutees in Building Engineering Design
In.Outer surface of steel tube is zinc-plated, not only reduces cost, and maintain hot dip galvanizing pipe be easy to hitch, installation, transport, it is resistance to collide with, it is resistance to
The premium properties such as mechanical wear, outer surface be attractive in appearance.Inner surface plastic-coated powdery paints, so that it may whole Optimalities with plastic-coated steel
Can, the bright and clean such as minute surface of such as film is difficult breed bacteria and microorganism, with effective anti-structural behaviour, resistance of water conveyance coefficient is small,
Increase conveyance power of water, carrying capacity more than 10%, reduction water delivery power consumption 15% are improved than inwall coating steel pipe.If installed
Afterwards, Several Thiourea Derivatives on Zinc Plate Surface applies aluminium paint again, normal service life up to a century more than, this just and building service life it is adaptable,
Avoid just changing water-supply-pipe at regular intervals, it is not only economical but also the life-span of building will not be influenceed because changing water-supply-pipe.
Utility model content
The purpose of this utility model is to overcome that of the prior art not enough there is provided a kind of low temperature resistant galvanized pipe, the galvanized pipe
By the packing layer being cased with galvanized pipe in plastic tube and interlayer cavity body, increase the intensity of galvanized pipe, and in plastic tube
Side and galvanized pipe outermost are equipped with layer of silica gel, have the advantages that intensity is high, low temperature resistant, be difficult breach.
What the technical solution of the utility model was realized in：A kind of low temperature resistant galvanized pipe, including galvanized pipe matrix, institute
State and plastic tube is arranged with galvanized pipe matrix, packing layer, coating steel pipe outer wall are provided with the cavity between plastic tube and galvanized pipe
Provided with zinc coat, passivation layer, layer of silica gel is provided with the inside of plastic tube.
Preferably, described filler layer includes pitch, elastomer and inorganic fillings composition.
As another preferred, heat-insulation layer is provided with the outside of the passivation layer.It is provided at an outer portion with heat-insulation layer so that too low in temperature
Under conditions of, it can also use.
Further, layer of silica gel is provided with the outside of the heat-insulation layer, has the advantages that intensity is high, low temperature resistant, is difficult breach.
Compared with prior art, advantage of the present utility model is as follows：The galvanized pipe passes through the interior plastic sleeve in zinc-plated tube body
Packing layer is provided with expects pipe and interlayer cavity body, the intensity of galvanized pipe is added, it is not easy to deform, and do not influence making for body
With extending service life；And the plastic tube and packing layer being provided with galvanized pipe also increase the corrosion resistance of galvanized pipe, in length
During phase use, will not because of fluid inside flowing, the galvanized pipe on the outside of corrosion also functions to the work increased the service life
With；It is provided at an outer portion with heat-insulation layer so that under conditions of temperature is too low, can also uses；On the inside of plastic tube provided with layer of silica gel with
And layer of silica gel is provided with the outside of heat-insulation layer, have the advantages that intensity is high, low temperature resistant, be difficult breach.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
Embodiment of the present utility model is as follows：
Embodiment 1：As shown in Figure 1：A kind of low temperature resistant galvanized pipe, including galvanized pipe matrix 1, the galvanized pipe matrix inner sleeve
Provided with plastic tube 2, packing layer 3 is provided with the cavity between plastic tube and galvanized pipe, coating steel pipe outer wall is provided with zinc coat 4, blunt
Change and layer of silica gel 6 is provided with the inside of layer 5, plastic tube.Described filler layer includes pitch, elastomer and inorganic fillings composition.It is described blunt
Change and heat-insulation layer 7 is provided with the outside of layer.Layer of silica gel 8 is provided with the outside of the heat-insulation layer.
Above-mentioned low temperature resistant galvanized pipe by the interior plastic pipe-covered and interlayer cavity body of zinc-plated tube body be provided with packing layer,
Add the intensity of galvanized pipe, it is not easy to deform, and do not influence the use of body, extend service life；And set in galvanized pipe
Some plastic tube and packing layer also increase the corrosion resistance of galvanized pipe, during long-term use, will not be because of fluid inside
Flowing, the galvanized pipe on the outside of corrosion also functions to the effect increased the service life；It is provided at an outer portion with heat-insulation layer so that in temperature
Under conditions of too low, it can also use；Provided with layer of silica gel is provided with the outside of layer of silica gel and heat-insulation layer on the inside of plastic tube, with intensity
Advantage that is high, low temperature resistant, being difficult breach.
Finally it is pointed out that above example is only the more representational example of the utility model.Obviously, this practicality is new
The technical scheme of type is not limited to above-described embodiment, can also there is many deformations.One of ordinary skill in the art can be from this reality
All deformations for directly being exported or being associated with new disclosure, are considered as protection domain of the present utility model.
