Description

The anti-collision plastic composite pipe

One, technical field

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

Two, background technique

As water pipe, use after several years, produce a large amount of rust deposites in the pipe, the yellow water of outflow not only pollutes sanitary equipment, and is being mingled with the bacterium that rough inwall grows, and corrosion causes in the water content of beary metal too high, the health of serious harm human body.In the past, the pipeline that is used to supply water mainly is a cast iron tube.The outdoor main sand mo(u)ld cast iron tube of using, indoor is zinc-plated cast iron tube.But be easy to generate a large amount of rust deposites afterwards in several years owing to use, breed bacteria, the health of serious harm human body, we often have such experience, several days no ones of family, the 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 modern people's needs.

Advantages such as that copper pipe has is corrosion-resistant, the bacterium that disappears be the prime quality in the water pipe, but a shortcoming of copper pipe are that heat conduction is fast, and another shortcoming is exactly that price is expensive; And traditional galvanized pipe easily gets rusty, perishable, easy fouling, grows microorganism easily, produces secondary pollution, threatens health; The composition of plastic tube has the chemical additives phthalein, and is very big to kidney in the human body, liver, testis influence, can cause cancer, kidney to damage, and destroys bodily fuctions's manufacturing system again, and influence is grown, and plastic tube easily breaks.To this, people need a kind of health, safe, durable water supply line to substitute them.

Three, summary of the invention

The objective of the invention is to solve the deficiency of above-mentioned existing water supply line, a kind of anti-collision plastic composite pipe be provided, make its have corrosion-resistant, be difficult for breaking, characteristics such as no chemical reaction, non-corrosive, non-scaling, long service life and cost are low.

The objective of the invention is to adopt following scheme to realize: a kind of anti-collision plastic composite pipe, it comprises plastic composite pipe body and anti-collision parts, be characterized in: described plastic composite pipe body is made up of spheroidal graphite cast iron and plastics, at plastic composite pipe body two ends flange plate is housed all; Described anti-collision parts are included in the stiffening rib on the external wall of plastic composite pipe and are fixed on reinforcing bar on the flange disc at the equally distributed circle two ends of external of plastic composite pipe.

Above-mentioned plastic composite pipe body is made up of spheroidal graphite cast iron and plastics, promptly is with centrifugally cast method ductile cast iron material to be cast as body, after the body cooling, sprays one deck plastics 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 plastic composite pipe, and it can reduce the plastic composite pipe gross weight, and reinforced plastics composite pipe structure intensity keeps the plastic composite pipe rigidity.

Above-mentioned flange plate also plays fixedly action of steel bars except that the connection that is used between the plastic composite pipe.

The two ends of above-mentioned reinforcing bar can directly be welded on the flange disc and also can be fixed on the flange plate with screw.Be contained in the external circle reinforcing bar of plastic composite pipe the encirclement of plastic composite pipe body is protected, can prevent effectively that plastic composite pipe from being broken.Need prevent heat dissipation when plastic composite pipe uses in the heating place, adorn foam this moment between reinforcing bar and plastic composite pipe body, constitute foam heat-insulation layer, and foam heat-insulation layer can not only be incubated the effect that can also play second protective layer.

The present invention adopts the beneficial effect of such scheme to be: the 1) use of stiffening rib and reinforcing bar has guaranteed the safety of plastic composite pipe can prevent effectively that plastic composite pipe from being broken; 2) composite pipe that forms by the casting of spheroidal graphite cast iron and plastics, that can effectively reduce plastics has the injury of chemical additives phthalein to human body; 3) plastic composite pipe has advantages such as acid-alkali-corrosive-resisting, weathering resistance, anti-sweep of gases, anti-ash cutting, anti-floating rust, and it is simple to operate, automaticity is high, equipment is simple; 4) inner-walls of duct of plastic composite pipe is smooth, so do not deposit paraffin, polymer and other sediments basically, guarantees not pollute the product that is transferred simultaneously.In addition, because internal face is smooth, friction factor is little, so under the transmitting power effect that equates, strengthened the passing capacity of pipeline widely, has reduced the conveying cost.
