Description

Anti-collision copper composite pipe

One, technical field

The present invention relates to a kind of composite pipe, especially a kind of anti-collision copper composite pipe.

Two, background technique

As water pipe, after using several years, produce a large amount of rust deposite in pipe, the yellow water of outflow not only pollutes sanitary equipment, and is mingled with the bacterium that rough inwall grows, and corrosion causes content of beary metal in water too high, the health of serious harm human body.Past, for the pipeline mainly cast iron tube supplied water.Sand mo(u)ld cast iron tube is mainly used in outdoor, and indoor is zinc-plated cast iron tube.But owing to easily producing a large amount of rust deposite after using several years, breed bacteria, the health of serious harm human body, we often have such experience, family several days no ones, tap of fetching boiling water, this is the best illustration of tubing polluted water to flow out yellow rust.Healthy water use, from pipe, a kind of health, safe, durable water pipe are the needs of modern people.

Copper pipe have corrosion-resistant, disappear the advantages such as bacterium, is the prime quality in water pipe, but copper pipe shortcoming to be heat conduction fast, another shortcoming is exactly price; And traditional galvanized pipe easily gets rusty, perishable, easy fouling, easy cooperating microorganisms, produces secondary pollution, threatens health; The composition of plastic tube has chemical additives phthalein, and on kidney, liver, testis impact in human body, very greatly, cancer, kidney can be caused to damage, destroy bodily fuctions's manufacturing system again, impact is grown, and plastic tube easily breaks.To this, people need a kind of health, safe, durable water supply line come alternative they.

Three, summary of the invention

The object of the invention is the deficiency that will solve above-mentioned existing water supply line, a kind of anti-collision copper composite pipe be provided, make it have corrosion-resistant, not easily break, without features such as chemical reaction, non-corrosive, non-scaling, long service life and cost are low.

The object of the invention is to adopt following scheme to realize: a kind of anti-collision copper composite pipe, it comprises copper composite pipe body and anti-collision part, be characterized in: described copper composite pipe body is composited by spheroidal graphite cast iron and copper metal centrifugal casting process, all flange plate is housed at copper composite pipe body two ends; Described anti-collision part is included in stiffening rib on copper composite pipe body outer wall and equally distributed circle two ends are fixed on the reinforcing bar on flange disc outside copper composite pipe body.

Above-mentioned copper composite pipe body is formed by spheroidal graphite cast iron and copper metal composite, namely first by centrifugally cast method, ductile cast iron material is cast as body, when casting temperature arrives 1400 DEG C-1800 DEG C, also cast last layer copper metal again by centrifugally cast method at inboard wall of tube body.

Above-mentioned stiffening rib is vertical bar shaped stiffening rib or spirality stiffening rib, and it is on the outer wall of copper composite pipe, and it can reduce copper composite pipe gross weight, strengthens copper composite pipe structure intensity, keeps copper composite pipe rigidity.

Above-mentioned flange plate is except for also playing fixing reinforcing bar except the connection between copper composite pipe.

The two ends of above-mentioned reinforcing bar directly can be welded on flange disc and also can be screwed on flange plate.The circle reinforcing bar be contained in outside copper composite pipe body surrounds copper composite pipe body and protects, and can effectively prevent copper composite pipe to be damaged.When this copper composite pipe needs to prevent heat loss when heating place and using, now between reinforcing bar and copper composite pipe body, fill foam, form foam heat-insulation layer, foam heat-insulation layer can not only be incubated the effect can also playing the second protective layer.

The present invention adopts the beneficial effect of such scheme to be: the 1) use of stiffening rib and reinforcing bar, ensure that the safety of copper composite pipe, can effectively prevent copper composite pipe to be damaged; 2) copper composite pipe has the advantages such as acid-alkali-corrosive-resisting, weathering resistance, resistance to sweep of gases, anti-ash cutting, anti-floating rust, and it is simple to operate, automaticity is high, equipment is simple; 3) inner-walls of duct of copper composite pipe is smooth, so substantially do not deposit paraffin, polymer and other sediments, ensures not pollute the product be transferred simultaneously.In addition, because internal face is smooth, friction factor is little, so under equal transmitting power effect, greatly enhance the passing capacity of pipeline, reduces conveying cost.
