Description
Technical field
The utility model relates to pipe technology field, particularly relates to a kind of glass fibre reinforced plastics PE composite pipe.
Background technique
Though existing simple glass steel pipe is provided with the multi-layer structure such as inside liner, interior winding layer, can be used for water engineering in theory, owing to containing the toxicant such as unsaturated resin and curing agent in Glass Steel Tube, in actual use, be generally not used in feedwater.As a kind of pipe of composite glass fiber reinforced plastics that patent publication No. provides for CN103292055A, tube wall is 4 layers, establishes inside liner, toughening layer, enhancement layer and protective coating successively from inside to outside, and each layer thickness, material all have design.Prehensile body is made, also have many in public technology, if patent publication No. is CN103343845A, disclosed a kind of continuous winding Glass Steel Tube, comprise inside liner, construction layer and external protection, construction layer is combined by the long fine layer of multilayer and the upper and lower interleaved of short fiber layer; Long fine layer cuts glass fibre by length and resin is formed, and short fiber layer is made up of short glass fiber, silica sand and resin.The program take resin as matrix, glass fibre is reinforcing material, silica sand is filler, adopts continuous winding technique to make.In addition, connection between pipeline all cannot solve the contact of body bulk material and institute's fed sheet of a media, if patent publication No. is CN101338844A, a kind of method of connecting glass fiber reinforced plastic, glass fibre reinforced plastics pipe is accepted head and whole Glass Steel Tube is disposable makes, pipe connection-peg is also disposable with whole Glass Steel Tube to be made, install seal ring additional and be located at conical internal thread root, outside is screwed into the Glass Steel Tube the other end with conical internal thread with the pipe connection-peg of conical external screw thread; And patent publication No. is CN102410422A, the Glass Steel Tube flange arrangement of design, Flange joint has pillar, and protective pipe sleeve is contained in the outside of body, just arranges pillar and protects body.
Summary of the invention
The purpose of this utility model cannot be directly used in solve existing pipe of composite glass fiber reinforced plastics the interface problem drunk between water engineering and pipeline, a kind of reasonable in design is provided, there is the glass fibre reinforced plastics PE composite pipe of mechanical strength characteristic sum PE hygienic environment-protecting feature.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: a kind of glass fibre reinforced plastics PE composite pipe, its pipe body comprises frp layer, it is characterized in that being provided with interior enhancement layer at described frp layer inwall, interior enhancement layer inwall is provided with PE layer; Frp layer outer surface is from inside to outside provided with outer reinforced layer, external protection successively; Described PE layer is shown outwards to overturn along pipe body two ends in pipe body, and to fit one section of flange length with external protection.
Glass fibre reinforced plastics and fiber-reinforced plastic, refer generally to glass fiber reinforcement unsaturated polyester, epoxy resin and phenolic resin as matrix resin, hard because of light weight, non-conductive, mechanical strength is high, corrosion-resistant and extensive use, and steel can be replaced as the manufactured materials of portioned product.Though but glass fibre reinforced plastics is hard but frangible, Young's modulus is low, less than steel 10 times, make product structure rigidity not enough, be easily out of shape; Long-term temperature tolerance is poor, though there is fire resistant resin, operating temperature is possible at 200 ~ 300 DEG C, as general purpose polyester FRP intensity more than 50 DEG C just obviously declines; Shear strength is low, because interlaminar shearing strength is born by resin; In addition also there is the harmful matter such as unsaturated resin and curing agent.The technical program is for these pluses and minuses of glass fibre reinforced plastics, using the basic framework of glass fibre reinforced plastics as pipe body, supplemental support is carried out at the inside and outside reinforced layer that arranges of pipe body, and PE layer is set at internal layer, made all areas of water on sanitary index, meet the NBS of PE feedwater piping, and to be turned up complete cladding process by termination, ensured that pipe body was in connection construction, anyly all may avoid exposing with contact position, water source, thus obtain a kind of aqueduct completely new product.As a kind of manufacture of larger diameter new product, this product can adopt canoe to produce, and more than coated to two ends PE layer flange, limit completes and provides condition, and this mode not only efficiency is high, process stabilization, controls very effective to length data.Winding compound between different materials, has strict design to temperature control, material mixture ratio, recombination time etc. parameter.
As preferably, the described PE layer length sleeve required when being connected with two branch pipe(tube) bodies of the length of fitting with external protection that turns up is suitable.Connecting between this case design pipe body adopts additional sleeve fashion as an example, and sleeve and the two pipe bodies PE layer that turns up merges completely.
As preferably, the length section position that described PE layer coordinates with sleeve is provided with the locating slot of rubber ring.By rubber ring strengthen sleeve to be connected with pipe body between sealing.
The beneficial effects of the utility model are: the mechanical strength property of Glass Steel Tube and PE hygienic environment-protecting characteristic are combined effectively, obtain the technical order such as pressure, rigidity and meet Glass Steel Tube NBS, and sanitary index meets the double technique effect of PE feedwater piping NBS, reliably water engineering can be applied to.
