The fiberglass mesh frame of the high-strength multi-layer pipe fitting is a reticular frame formed through left and right spirally winding high-strength multi-layer glass fibers and serves as an intensified body, and the fiberglass mesh frame is tightly connected through a high-performance bonding resin layer.
Description
Technical field
The utility model relates to a kind of link of supply pipe, particularly a kind of high-strength multilayer feedwater pipe fitting that is used for the connection between the high-strength multilayer supply pipe of heavy caliber or connects other pipeline.
Background technique
Pipeline in the tap water water supply network, a large amount of now novel water feed tube such as high density polyethylene (HDPE) supply pipe, the compound supply pipe of steel wire mesh frame polyethylene that adopt.Feedwater pipe fitting caliber is less at present, can not satisfy the needs of present municipal water supply pipeline; The caliber of novel supply pipe is bigger, can satisfy the city water requirements for pipes, is that make by hand at the scene but pipeline connects great majority, can't guarantee construction quality.Blocked up like a kind of its tube wall of plastic material pipe manufacturing of independent employing, also difficult realization summary of the invention is for addressing the above problem.
Summary of the invention
For solving the problem that prior art exists, the utility model provides the high-strength multilayer pipe fitting of a kind of glass fibre frame plastic to be used to strengthen the high connection pipe fitting between heavy caliber polyethylene/polyamide/fiberglass braided high-strength multilayer supply pipe just.
The utility model solves its technical problem, and the technological scheme that is adopted is: a kind of multilayer feedwater pipe fitting comprises: glass fiber mesh, polyethylene layer, aramid layer, flange.Pipe fitting has polyethylene layer, aramid layer, heat-fusing glue layer, glass fibre wound web, heat-fusing glue layer, aramid layer, polyethylene layer respectively; By polyethylene layer, aramid layer is matrix, with binder glass fibre network framework and aramid layer is linked together; Use the intensity skeleton of confined bed of fiberglass braided one-tenth as tubing; The pipe fitting termination is that flange connects; Pipe fitting can be 45 ° of elbows, pipe fittings and can be 90 ° of elbows, pipe fittings and can be equal tee, pipe fitting and also can be the direct pipe fitting of reducing.
The beneficial effect of the utility model is: both can be used for strengthening high heavy caliber polyethylene/polyamide/glass fibre just
Connection between the high-strength multilayer supply pipe of dimension braiding also can be used for strengthening high firm heavy caliber polyethylene/polyamide/fiberglass braided high-strength multilayer supply pipe and is connected with other PE pipe.The high-strength multilayer pipe fitting of glass fibre network framework polyethylene is to serve as to strengthen body with the helically-wound shaped mesh skeleton in the high strength glass fiber left and right sides; With high density polyethylene (HDPE), polyamide is matrix, and with high performance adhering resin layer the glass fibre network framework is closely linked together.Polyamide, polyethylene are extruded through plastic extruder and are once become pipe.The thermosol adhesive layer can guarantee the adhesive capacity of polyamide and fiberglass braided layer.
The beneficial effect of the utility model is: 1 glass fibre network framework is better than steel-wire carcass through PUR adhesive bond effect with polyamide; 2 glass fibres substitute steel wire as the tubing skeleton, can avoid in the underground water crystallization to decompose the severe corrosive of complex class weak erosive material to steel wire, can in peracidity, high alkalinity soil strong corrosive environment, use; 3 glass fibre expansion coefficient are close with polyethylene/polyamide, can avoid steel wire and the plastics stratification that expanded by heating causes when temperature variation.
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.

Fig. 2 is the sectional drawing of 90 ° of bend pipe tools of multilayer feedwater pipe fitting;
Fig. 3 is the sectional drawing of the equal tee pipe fitting of multilayer feedwater pipe fitting;
Fig. 4 is the sectional drawing of the direct pipe fitting of reducing of multilayer feedwater pipe fitting.
Shown in the figure: polyethylene layer 1, aramid layer 2, glass fiber mesh 3, flange 4.
Embodiment
The utility model is described to be the high-strength multilayer pipe fitting of glass fibre network framework polyethylene, and this tube material mainly is made up of polyethylene, polyamide, glass fibre wound web.Have seven layers from inside to outside, be respectively polyethylene layer, aramid layer, heat-fusing glue layer, glass fibre wound web, heat-fusing glue layer, aramid layer, polyethylene layer.This pipe fitting is to serve as to strengthen body with the helically-wound shaped mesh skeleton in the high-strength multilayer degree glass fibre left and right sides, is matrix with high density polyethylene (HDPE) (HDPE), polyamide, and with high performance binder glass fibre network framework and polyamide is closely linked together.Polyethylene is extruded the once-through pipe fitting through plastic extruder.The pipe fitting termination is that flange connects, and links together tubing and pipe fitting reliably.As shown in the figure, we are decomposed into following several sections to the performance requirement of tubing, are born by various piece respectively.At first be the internal pressure strength of tubing, it is born by fiberglass braided part, and fiberglass braided one-tenth can form a tight confined bed, as the intensity skeleton of tubing, can realize the compressive strength of tubing; Next is the ring stiffness requirement of tubing, and it is born by nylon rigidity framework layer, selects the nylon material of the high elastic modulus of modification, can significantly increase the ring stiffness of tubing; Secondly be internal friction coefficient, wholesomeness, corrosion protection and the barrier type of tubing again, this polyethylene by internal layer is born; Be the anticorrosive property and long-term working life of outer pipe wall at last, it is born by the polyethylene of outermost wall.This pipe fitting mainly can have 45 ° of elbows, 90 ° of elbows, equal tee, isometrical directly, form such as the electric smelting reducing is direct; Both can be used for strengthening the high connection between heavy caliber polyethylene/polyamide/fiberglass braided high-strength multilayer supply pipe just, and also can be used for strengthening high firm heavy caliber polyethylene/polyamide/fiberglass braided high-strength multilayer supply pipe and be connected with other PE pipe.
