Abstract
The utility model relates to a metal and plastic composite tube privately used in polyethylene-aluminum composite pipeline. The utility model is one-off made of particular engineering plastic. The utility model comprises a tube body. the utility model is characterized in that the middle of the tube body is concave and each end is convex to form an end surface stair shape with concave outer part and convex inner part; the inner wall of the tube is slick; a bowl type metal crush compressing ring is embedded inside a round cone which is convex outwards; and the end of the tube is provided with a material storing groove with a chamfer angle of 45 DEGs. The plastic tube can take a straight way valve with equal diameter, different diameter and metal embedded inner and outer screw thread, a three way valve with equal diameter, different diameter and metal embedded inner and outer screw thread, or bent way valve with equal diameter, different diameter and metal embedded inner and outer screw thread and a tube cap. the utility model has the advantages of compression resistance, hot water and high temperature resistance, corrosion resistance, long useful time, little flow resistance, no innocuous and healthful, satisfying the environment protection requirement, easy mounting, easy operation, saving material and low cost.
Description
Technical field
The utility model relates to composite tube of metal and plastic, particularly aluminium-plastic composite pipe special-purpose metal plastic composite pipe.
Background technique
Aluminium-plastic composite pipe is the advanced composite material (ACM) pipeline that a kind of combination property is better than metallic conduit and nonmetal pipeline.Its tolerance external and internal pressure performance, be difficult for embrittlement, expansivity and compactness, ooze the excellent properties that aspect such as oxygen rate has metallic conduit; Aspects such as its corrosion resistance, the life-span is long, flow resistance is little have the excellent properties of plastic pipe again.It is nontoxic, pollution-free, meet national GB5794 " drinking water sanitary standard " fully, is a kind of desirable following pipeline.
Pipe fitting, promptly the joint of various connecting tubes is necessary devices supporting with aluminium-plastic composite pipe.When at present both at home and abroad using plastic-aluminum combined, all can only the adapted metal pipe element, and metal pipe element complex structure and cost of production height have influenced the universal use of aluminium-plastic composite pipe.
Summary of the invention
For this reason, the utility model designer researchs and develops out a kind of aluminium-plastic composite pipe special use (hot water) composite tube of metal and plastic.
This composite pipe fitting is with special engineering plastics and metal, makes with one-shot forming technique, and it comprises pipe fitting, it is characterized in that pipe fitting is that the middle part is recessed, each port projection makes tube wall thickness evenly and more help bearing pressure and aesthetic in appearance, and the step that forms outer recessed convex is used for the end face thermal fusion welding; The inner wall smooth of pipe fitting can reduce flow resistance, and edge buries the metal pressure-resistent ring of a bowl type in the cylinder of outer lug, and the effect of this pressure-resistent ring is that the restriction plastic pipe is met heat and is subjected to the compression swelling modification, and the bonding layer that causes aluminium-plastic composite pipe separates and causes managing the top layer explosion.Inserting when the end face of the step end face of internal projection and port cylinder inner wall and body and periphery are heated to melt simultaneously by the electric heating instrument and making pipe fitting and body welding is one, reach pipe fitting and firmly be connected purpose with body, while pipe fitting internal projection step end face and pipe fitting end face also hermetica seal get up, and aluminium lamination can be by fluid erosion, decomposition in the protection plastic-aluminum pipe; The pipe fitting port has the material-storing groove that is 45 ° of chamferings, and the body that makes the surface be in melt injects the unnecessary melt plastics of outwards extruding when inwall also is in the body of melt body and is stored in the chamfering groove, forms a circle convex ring shape and makes interface more firm, attractive in appearance.This plastic pipe can be isometrical or the inside and outside rib-loop of reducing or metal inlaying is straight-through, isometrical or reducing or the threeway of metal inlaying internal and external threads, isometrical or reducing or metal inlaying internal and external threads are bent and passed to and pipe cap or the like.This plastic pipe can have internal and external screw thread.
Plastic pipe of the present utility model is simple in structure, has following premium properties:
Compression resistance: can bear the pressure test that is greater than or equal to the aluminium-plastic composite pipe NBS;
Corrosion-resistant: as to be insoluble to any known solvent;
Life-span is long: its aging quality resistance is identical with aluminium-plastic composite pipe;
Flow resistance is little: pipe fitting inner wall degree of finish is than aluminium-plastic composite pipe height, and flow resistance is littler than metal pipe element;
Non-toxic sanitary: meet national GB5794 " drinking water sanitary standard ";
Environmental protection, waste and old engineering plastics usefulness more capable of circulation can not pollute environment;
The mounting process of pipe fitting is simple;
The material and the moulding process cost of aluminium-plastic composite pipe special use (hot water) composite tube of metal and plastic are low, and price is more much lower than metal pipe element.The aluminium-plastic composite pipe that promote the wider application is had very big promotion, and market prospects are fine.

Embodiment
Shown in Fig. 2 and 4, Fig. 2 is six views of equal tee composite tube of metal and plastic, and Fig. 4 is the sectional view of equal tee composite tube of metal and plastic.The equal tee composite tube of metal and plastic comprises pipe fitting 1; it is characterized in that pipe fitting is the step shape of outer recessed convex and the inner wall smooth of pipe fitting; edge buries the metal pressure-resistent ring 3 of a bowl type in the cylinder of outer lug; the end face 4 of the step end face 4 of internal projection and cylinder inner wall 5 and body and periphery 5 insert when being heated to melt simultaneously by the electric heating instrument; making pipe fitting and body welding is one; pipe fitting raised step end face 4 gets up with pipe fitting end face also hermetica seal simultaneously, and the aluminium lamination in the protection aluminium-plastic composite pipe can not invaded by fluid and be melted, decomposes.The degree of depth and the length of control thermal fusing surface make the leftover and plastic of inwardly extruding minimum, avoid causing internal diameter to dwindle, and influence flow.The pipe fitting port has the material-storing groove that is 45 ° of chamferings, and the body that makes the surface be in the hot melt state injects the unnecessary melt plastics of outwards extruding when inwall also is in the pipe fitting of melt body and is stored in the chamfering groove, forms a circle convex ring shape 6, makes interface more firm, attractive in appearance.
