Abstract
The utility model discloses a metal-plastic composite bend pipe piece, relates to an accessory of indoor and outdoor plastic drainage pipes of a building, and belongs to the field of plastic composite pipelines. The metal-plastic composite bend pipe piece is characterized in that the metal-plastic composite bend pipe piece is of a double-layer structure and is formed in a manner of compositing a metal bend inner layer and a plastic bend outer layer integrally. By applying the metal-plastic composite bend pipe piece, the problem that the plastic drainage pipe bend is not impact-resistant is solved, and the advantages of metal and plastic are combined together perfectly.
Description
Technical field
The utility model relates to the pipe fitting in the drain pipe system using in a kind of daily life, specially refers to by metal and the compound high strength that forms of plastics, the elbow of high-impact.
Background technique
China is building internal drainage pipe field at present, adopts plastic tube universal, and construction drainage pipe is traditionally cylinder iron to manage, because cast iron tube energy consumption is high, it is unreliable to connect, and construction is inconvenient, and construction drainage is successfully replaced by plastic tube.Although plastic tube is using in a large number, also has its shortcoming.Be exactly that shock resistance is poor, the mass-flow that the elbow that particularly bottom of the standpipe of plastic drain-pipe and the joint of transverse tube adopt is often fallen by eminence impacts, and is washed for a long time rear elbow and is broken.
Summary of the invention
Goal of the invention of the present utility model: high strength, high-impact is the advantage of metal, good corrosion resistance, cementability is well the advantage of plastics.Two kinds of advantages together, provide the high strength of a kind of metal and the compound composition of plastics, high-impact, the easy and bonding elbow of plastic drain-pipe.In order better to complete foregoing invention, the utility model is to realize like this.A kind of metallo-plastic bend pipe tools, is characterized in that elbow body is divided into double-layer structure, integral by metal bends body inner tube and the external pipe complex group of plastic elbow.Because stainless steel tensile strength is high, moderate cost, so metal preferentially adopts stainless steel.Because PVC and ABS are good with glue cementability, therefore plastics adopt PVC or ABS.The bonding plastics of some not easy-to-use glue are as PP, and PE is difficult for adopting in the utility model.Two end bells of composite elbow (plastic drain-pipe apply glue insert or screw in realize bonding) are divided into four kinds of structures: two end bells of 1 composite elbow are monolayer plastic; The bellmouth part at 2 composite elbow two ends is monolayer plastic, and another part is metallo-plastic composite bed; Two end bell one end of 3 composite elbows are monolayer plastic, and a other end bellmouth part is monolayer plastic, and another part is metallo-plastic composite bed; The bellmouth both ends or one end of 4 composite elbows are internal thread.The utility model can create by traditional manufacture method, first metal tube is curved to the elbow of required angle, put into injection mould and locate the plastic pellet high pressure injection mould that closed die has dissolved by injection machine handle, depanning after cooling forming, so just can obtain elbow that metal and plastics are combined into one.But make that manufacturing equipment is large in this way, cost is high, particularly has the elbow of internal thread bellmouth, mould structure complexity, manufacture difficulty is large.In order to make metal and plastics composite bent easy first watch, more economical creates, and a kind of metallo-plastic composite elbow pipe fitting, is characterized in that: plastic elbow body can be divided into two lobes, deciliter locate outwardly limit, plastic elbow body two lobes and metal bends body are bonding or hot melt complex group is integral.

Embodiment
In order better to understand model utility structure characteristic, below in conjunction with accompanying drawing, the utility model is further elaborated.For better, from Economy, the convenience of installation, considers in the difficulty of impact resistance and manufacture, the following five kinds of mode of executions of the utility model arrangement:
Specific embodiment one
As shown in Figure 1: a kind of metallo-plastic composite elbow pipe fitting, it is characterized in that elbow body is divided into double-layer structure, internal layer is metal bends body, and skin is plastic elbow body, and described internal and external layer complex group is integral, and the bellmouth at two ends is monolayer plastic.
Specific embodiment two
As shown in Figure 2: a kind of metallo-plastic composite elbow pipe fitting, it is characterized in that elbow body is divided into double-layer structure, internal layer is metal bends body, skin is plastic elbow body, described internal and external layer complex group is integral, and the bellmouth part at two ends is monolayer plastic, and another part is metallo-plastic composite bed.
Specific embodiment three
As shown in Figure 3: a kind of metallo-plastic composite elbow pipe fitting, it is characterized in that elbow body is divided into double-layer structure, internal layer is metal bends body, skin is plastic elbow body, described internal and external layer complex group is integral, the bellmouth one end at two ends is monolayer plastic, and a other end bellmouth part is monolayer plastic, and another part is metallo-plastic composite bed.
Specific embodiment four
As shown in Figure 4: a kind of metallo-plastic composite elbow pipe fitting, it is characterized in that elbow body is divided into double-layer structure, internal layer is metal bends body, and skin is plastic elbow body, and described internal and external layer complex group is integral, and the bellmouth of both ends or one end is internal thread.
Specific embodiment five
As shown in Figure 5: a kind of metallo-plastic composite elbow pipe fitting, it is characterized in that elbow body is divided into double-layer structure, internal layer is metal bends body, skin is plastic elbow body, plastic elbow body is divided into two lobes, deciliter locate outwardly limit (being in order to increase by two lobes bonding plane altogether), plastic elbow body two lobes and metal bends bluk recombination composition one.The object of this structure is for more convenient, more economical creates composite elbow, so plastic elbow body is divided into two lobes (as shown in the figure 10,20), by hot melt or bonding integral two lobes of plastic elbow body and metal bends body (as shown in the figure 30) complex group.Note: in Fig. 5, a is the view of a lobe of plastic elbow body, and c is the view of another lobe of plastic elbow body, and b is the view of metal bends body.
Value of the present utility model is the advantage of metal and plastics perfectly to combine, and has solved the not impact-resistant problem of plastic draining pipe bend, has eliminated the weak link in plastic draining system.
