Abstract
The utility model discloses a steel wire frame plastic combined elbow, relating to a liquid continuous transmission pipe elbow fitting, in particular to a combined elbow. The steel wire frame plastic combined elbow comprises an upper straight pipe (A), a lower straight pipe (B) and a connecting pipe (C), wherein, an angle of 90 degrees is formed between the axes of the upper straight pipe (A) and the lower straight pipe (B); the connecting pipe (C) is a cambered elbow structure, and both ends of the connecting pipe (C) are respectively connected with one port of the upper straight pipe (A) and one port of the lower straight pipe (B); the wall of the combined elbow is composed of five layers which include an inner plastic pipe (1), an inner hot melt adhesive layer (2), a twisted steel wire (3), an outer hot melt adhesive layer (4) and an outer plastic pipe (5), all of which are arranged sequentially from the inside to the outside and adhered together solidly. The utility model solves the problems existed in the existing elbow fitting, namely, severe corrosion, difficulty in construction, high maintenance cost and pollution to the transmission medium.
Description
Technical field
The utility model relates to continuous liquid conveying pipeline bend pipe fitting, particularly a kind of composite pipe elbow.
Background technique
At present China oil field, some liquid of mine are carried, and adopt metal tube or nonmetal multiple tube and pipe fitting more, and when carrying liquid, pipeline, pipe fitting seriously corroded some races occur, emit phenomenon such as leakage, and the working life of pipeline, pipe fitting is short; But not the metal composite pipe fitting is then produced, installation cost is higher; In these pipelines of littoral, pipe fitting constructional difficulties, soldering point is many, and the maintenance cost height produces pollution to fed sheet of a media, has seriously restricted the application of these pipelines and pipe fitting.
The model utility content
The purpose of this utility model provides a kind of steel wire mesh frame plastic composite elbow, and the utility model has solved the seriously corroded that existing pipe fitting exists, constructional difficulties, and the maintenance cost height produces pollution problems to fed sheet of a media.
Steel wire mesh frame plastic composite elbow of the present utility model, comprise top straight tube A, bottom straight tube B and connecting tube C, form 90 degree angles between the axis of top straight tube A and bottom straight tube B, described connecting tube C is the curve bend structure, and the two ends of connecting tube C connect the port of top straight tube A and bottom straight tube B respectively; The tube wall of described composite elbow is made up of five-layer structure, and composite pipe is followed successively by inner layer plastic tube 1, interior heat-fusing glue layer 2, winding steel wire net 3, external hot melting glue-line 4, outer layer plastic tube 5 from inside to outside, firm bonding of above-mentioned five-layer structure.
Steel wire mesh frame plastic composite elbow of the present utility model, application area has: medium transport such as the oil of (1) oil field gathering and transportation oil pipe, conduit pipe and high sulfur-bearing, gas, water.(2) urban construction, urban water supply and sewerage, municipal natural gas supply engineering.(3) coalmine ventilation pipe, coal seam tracheae and conveying solid-liquid mixing water coal slurry.(4) the ore pulp conveyance conduit of coal mining such as various chemical industry ore deposit, nonferrous metals ore, gold mine, copper mine and ore dressing.The conveying of (5) plumbing in power plant and chemical plant, fire-fighting and sulfuric acid corrosion resistance medium.
Steel wire mesh frame plastic composite elbow of the present utility model has not corrosion pipeline, is convenient to construction, and maintenance cost is low, to the free of contamination advantage of fed sheet of a media.
Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is the sectional view of the utility model steel wire mesh frame plastic composite elbow tube wall.
Symbol description among the figure: top straight tube A, bottom straight tube B, connecting tube C, inner layer plastic tube 1, interior heat-fusing glue layer 2, winding steel wire net 3, external hot melting glue-line 4, outer layer plastic tube 5.
Embodiment
Below in conjunction with accompanying drawing and with illustrated embodiments the utility model is done detailed explanation.
Consult Fig. 1, Fig. 2, the steel wire mesh frame plastic composite elbow, comprise top straight tube A, bottom straight tube B and connecting tube C, form 90 degree angles between the axis of top straight tube A and bottom straight tube B, described connecting tube C is the curve bend structure, and the two ends of connecting tube C connect the port of top straight tube A and bottom straight tube B respectively; The tube wall of described composite elbow is made up of five-layer structure, and composite pipe is followed successively by inner layer plastic tube 1, interior heat-fusing glue layer 2, winding steel wire net 3, external hot melting glue-line 4, outer layer plastic tube 5 from inside to outside, firm bonding of above-mentioned five-layer structure.
Steel wire mesh frame plastic composite elbow of the present utility model, be a kind of novel environment friendly building materials, it be in the middle of inner layer tube wall and outer wall uniform winding the enhancing steel wire, and extrude the high-performance adhesive material by the intermediate node layer, with high-tensile steel wires and internal and external layer PE hot melt adhesion is one, thus the composite pipe fitting that acquisition has function admirable.
Claims (1)
