Abstract
The utility model discloses a glass fiber reinforced plastics lining pipe comprising a glass fiber reinforced plastics layer. An inner PE (polyethylene) pipe is arranged on the inner wall of the glass fiber reinforced plastics layer. A hollow PE helical rib pipe winding the outer wall of the inner PE pipe is fused on the periphery of the inner PE pipe and is nested in the inner wall of the glass reinforced plastic layers. The inner PE pipe has better moistureproof and anti-corrosive performance and is less prone to ageing, the glass fiber reinforced plastics layer is high in rigidity and mechanical strength, the inner PE pipe and the glass fiber reinforced plastics layer are mutually matched to be complementary, aging of the glass fiber reinforced plastics lining pipe is integrally slowed down, and service life is prolonged. PE is food sanitation materials, and the glass fiber reinforced plastics lining pipe is applicable to the field of water supply pipes. The glass fiber reinforced plastics layer and the inner PE pipe are difference in thermal expansion coefficient and have a gap therebetween, and the inner PE pipe is not separated from the glass fiber reinforced plastics layer by the PE helical rib pipe. The PE helical rib pipe is hollow, materials are saved, pressure of the inner PE pipe is buffered, and possibility of bursting of the pipe stressed is reduced.
Description
Technical field
The utility model belongs to tubing field, is specifically related to a kind of Glass Steel Tube structure.
Background technique
Existing Glass Steel Tube also claims glass fiber winding clamp sand pipe (RPM pipe).Mainly taking glass fibre and goods thereof as reinforcing material, taking unsaturated polyester resin, the epoxy resin etc. of macromolecule component as body material, using the inorganic non-metallic such as silica sand and calcium carbonate granular material as filler is as main raw material.Glass Steel Tube has that quality is light, rigidity is high, cheap, the easy for installation series of advantages of Jie's lattice.Its weakness is also obvious: be subject to sunlight, humidity easily aging for a long time, its correlated performance cannot ensure.
Summary of the invention
Technical problem to be solved in the utility model is: for prior art exist deficiency, a kind of novel structure compactness is provided, be not easy aging, the glass fibre reinforced plastics plastics lined pipe of long service life.
For realizing the object of the utility model, be achieved by the following technical solutions: a kind of glass fibre reinforced plastics plastics lined pipe, include frp layer, frp layer inwall is provided with one deck PE inner tube, the welding of PE inner tube periphery has the hollow PE spiral reinforcement pipe of spiral winding at PE outer wall of inner tube, and PE spiral reinforcement pipe is embedded in frp layer inwall.
As preferred version: the thickness b of described PE inner tube is the 1/7-1/6 of frp layer thickness a, and in the time of this ratio range, PE inner tube and frp layer all can be brought into play advantage separately best, have higher cost performance; The external diameter c of described PE spiral reinforcement pipe is the 1/3-1/2 of frp layer thickness a, can ensure that the rigidity of frp layer is not subject to the impact of PE spiral reinforcement pipe in the time of this ratio range, and PE spiral reinforcement pipe can be brought into play and connect PE inner tube and the function of frp layer and the function of buffering; The wall thickness of described PE spiral reinforcement pipe is 1/7 of its external diameter, and PE spiral reinforcement pipe can be brought into play its function and save again PE raw material most like this; The pitch of described PE spiral reinforcement pipe is 1/10 of frp layer external diameter, and PE spiral reinforcement pipe can make the relative position of PE inner tube and frp layer fix like this, and each position of tubing is stressed evenly, is beneficial to prolongation whole service life.
Compared with prior art, the beneficial effects of the utility model are: described PE inner tube has better damp proof antiseptic property, be not easy aging, frp layer has higher hardness and mechanical strength, both complement each other to form complementation, slow down on the whole the aging of this kind of glass fibre reinforced plastics plastics lined pipe, extended working life.PE is food stage hygienic material, makes this tubing be applicable to supply pipe field.Described frp layer is different with PE inner tube thermal expansion coefficient, can produce gap between the two, described PE spiral reinforcement pipe can not depart from frp layer PE inner tube, and PE spiral reinforcement pipe is hollow, when saving material, play the effect of buffering PE inner tube portion pressure, reduced tubing pressurized and produced the possibility of breaking.

Embodiment
With reference to the accompanying drawings embodiment of the present utility model is made a detailed explanation below.
According to shown in Fig. 1 to Fig. 2, a kind of glass fibre reinforced plastics plastics lined pipe described in the present embodiment, includes frp layer 1, and frp layer inwall is provided with one deck PE inner tube 2, the welding of PE inner tube periphery has the hollow PE spiral reinforcement pipe 3 of spiral winding at PE outer wall of inner tube, and PE spiral reinforcement pipe is embedded in frp layer 1 inwall.Described PE inner tube has better damp proof antiseptic property, is not easy agingly, and frp layer has higher hardness and mechanical strength, and both complement each other to form complementation, have slowed down on the whole the aging of this kind of glass fibre reinforced plastics plastics lined pipe, have extended working life.PE is food stage hygienic material, makes this tubing be applicable to supply pipe field.Described frp layer is different with PE inner tube thermal expansion coefficient, can produce gap between the two, described PE spiral reinforcement pipe can not depart from frp layer PE inner tube, and PE spiral reinforcement pipe is hollow, when saving material, play the effect of buffering PE inner tube portion pressure, reduced tubing pressurized and produced the possibility of breaking.
The thickness b of described PE inner tube is 1/6 of frp layer thickness a, and in the time of this ratio range, PE inner tube and frp layer all can be brought into play advantage separately best, have higher cost performance; The external diameter c of described PE spiral reinforcement pipe is 1/3 of frp layer thickness a, can ensure that the rigidity of frp layer is not subject to the impact of PE spiral reinforcement pipe in the time of this ratio range, and PE spiral reinforcement pipe can be brought into play and connect PE inner tube and the function of frp layer and the function of buffering; The wall thickness of described PE spiral reinforcement pipe is 1/7 of its external diameter, and PE spiral reinforcement pipe can be brought into play its function and save again PE raw material most like this; The pitch of described PE spiral reinforcement pipe is 1/10 of frp layer external diameter, and PE spiral reinforcement pipe can make the relative position of PE inner tube and frp layer fix like this, and each position of tubing is stressed evenly, is beneficial to prolongation whole service life.
