Abstract
The utility model relates to a high-abrasion-resistant steel-plastic composite pipe fitting, which mainly solves problems that existing pipe fittings with fine abrasion resistance are poor in pressure resistance or the existing pipe fittings with fine pressure resistance are poor in abrasion resistance. The high-abrasion-resistant steel-plastic component pipe fitting is characterized in that an inner bush (3) made of polyethylene with ultrahigh molecular weight is bonded onto the inner wall of a base (1) made of high-density polyethylene and the end of the pipe fitting. The pipe fitting has the advantages of abrasion resistance and pressure resistance.
Description
Technical field
The utility model relates to a kind of high abrasion composite steel-plastic pipe fitting, belongs to technical field of plastic.
Background technique
At present, the wear-resisting pipe fitting on the market mainly comprises pure wear-resisting pipe fitting and two kinds of product forms of the pure plastic pipe of multilayer moulded.The raw material of these two kinds of wear-resisting parts of pipeline is ultra-high molecular weight polyethylene, is called for short UHMW-PE, and the former all adopts wear-resisting raw material by tubing, and the latter partly adopts wear-resisting raw material, and these two kinds of pipe fitting wear-resisting propertys are good, but resistance to pressure is poor.Composite steel-plastic pipe fitting is to be matrix with high density polyethylene (HDPE) (HDPE), and Steel Skeleton is a reinforcing phase, takes fixedly skeleton of certain mode in forming process, utilizes the pipe fitting mold injection-compression molding, and resistance to pressure is good, but the high density polyethylene (HDPE) matrix is but not wear-resisting.
Summary of the invention
For wear-resisting but not withstand voltage, the withstand voltage but not wear-resisting problem that has that overcome that existing pipe fitting has, the utility model provides a kind of high abrasion composite steel-plastic pipe fitting, and it is wear-resisting withstand voltage again characteristics that this high abrasion composite steel-plastic pipe fitting has.
The technical solution of the utility model is: a kind of high abrasion composite steel-plastic pipe fitting, comprise high density polyethylene (HDPE) matrix and inner Steel Skeleton thereof, and reach pipe fitting end on the high density polyethylene (HDPE) matrix inwall and be bonded with the ultra-high molecular weight polyethylene neck bush.
The utlity model has following beneficial effect: owing to take such scheme, on high density polyethylene (HDPE) matrix inwall, be bonded with the ultra-high molecular weight polyethylene neck bush, utilize the wear-resisting property of ultra-high molecular weight polyethylene, make pipe fitting also more wear-resisting in withstand voltage, improve the using scope of pipe fitting, prolonged its working life.
Description of drawings:
Fig. 1 is the structural representation of elbow in the utility model;
Fig. 2 is the structural representation of threeway in the utility model.
1-high density polyethylene (HDPE) matrix among the figure, 2-Steel Skeleton, 3-ultra-high molecular weight polyethylene neck bush.
Embodiment:
Below the utility model is described in further detail:
By shown in Figure 1, a kind of high abrasion composite steel-plastic pipe fitting, comprise high density polyethylene (HDPE) matrix 1 and inner Steel Skeleton 2 thereof, Steel Skeleton 2 makes this pipe fitting more withstand voltage, reach pipe fitting end on high density polyethylene (HDPE) matrix 1 inwall and be bonded with ultra-high molecular weight polyethylene neck bush 3, ultra-high molecular weight polyethylene neck bush 3 can utilize molded prefabricated forming, also can adopt multi-layer co-extruded mode moulding, its internal diameter size is as the criterion with product specification, prefabricated neck bush is placed in the pipe fitting mold, with the high density polyethylene (HDPE) is that raw material carries out pressure injection, carries out post forming.
Compare pure pipe and the pure pipe of moulding of multilayer moulded of UHMW-PE, this high abrasion composite steel-plastic pipe fitting uses a spot of high-abrasive material just can reach usage requirement, the cost of raw material is lower, it is easier to process, simultaneously, this pipe fitting has higher strength and stiffness, can significantly improve the resistance to compression grade of wear-resisting pipe fitting, better weldability is arranged, and pipeline connects more simple; Compare with the plain carbon steel plastic composite, this pipe fitting has better wear resistance.
Claims (1)
1. a high abrasion composite steel-plastic pipe fitting comprises high density polyethylene (HDPE) matrix (1) and inner Steel Skeleton (2) thereof, it is characterized in that: reach pipe fitting end on high density polyethylene (HDPE) matrix (1) inwall and be bonded with ultra-high molecular weight polyethylene neck bush (3).
