Abstract
The utility model provides a plastics double-wall wounded corrugated pipe, which is obtained by spirally winding plastic square pipe and by welding through hot-melt adhesive, wherein the internal side edge of the plastic square pipe is extended towards two sides and formed with a short edge, and the hot-melt adhesive is connected between the short edges of two adjacent plastic square pipes to form the walls of the corrugated pipe. The utility model has the advantages of reasonable structure, raw material-saving, firm sol welding and high ring stiffness.
Description
Technical field
The utility model relates to a kind of plastic tube, relates in particular to a kind of plastic double walls winding corrugated furnace and preparation method thereof.
Background technique
At present, the tubing that domestic underground water supply and drainage pipe-line system is used mainly contains concrete pipe, concrete reinforced pipe and cast iron tube, because it is bigger than length and vehicle flowrate that it builds the time limit, the buried concrete waste pipe in some highway section and cast iron water pipe are damaged in succession aging, cause municipal drainage to stop up, the water pipe explosion, not only bring inconvenience to citizen's life, and because of working procedure complicated, the pipe joint number is more, leakage proof is difficult in time handling, accumulate over a long period and not only can cause road foundation to sink, effluent seepage, also can pollute soil property, the water source becomes public hazards.For this reason, adopt have good withstand voltage, light weight, corrosion-resistant, environment protection type tubing become the task of top priority.
Recent years, all types of plastic tubing rises gradually at home, and progressively replaces concrete pipe, concrete reinforced pipe and cast iron tube.With respect to concrete pipe, concrete reinforced pipe and cast iron tube, plastic tube have light weight, corrosion-resistant, the low pollution or free of contamination remarkable advantage, and plastic tube is also longer working life under identical withstand voltage condition.What plastic tube was relatively more commonly used at present is the pvc pipe material, though price is lower, it is heavier to exist quality, and withstand voltage deficiency has shortcomings such as a small amount of pollution.And the HDPE solid wall pipe, though function admirable, cost is higher, waste material.
The model utility content
The purpose of this utility model in order to overcome the problems referred to above that prior art exists, provides a kind of plastic double walls winding corrugated furnace with new structure exactly.
The purpose of this utility model is achieved in that a kind of plastic double walls winding corrugated furnace, be made of welded connection by the winding of plastics square tube spiral and with hot melt adhesive, the inner side edge of described plastics square tube is extended with a minor face to both sides, hot melt adhesive is connected between the minor face of each adjacent two plastics square tube, forms corrugated pipeline wall.
The outer side surface of described plastics square tube is a fillet for two jiaos.
The utility model plastic double walls winding corrugated furnace makes it compared with prior art owing to adopted above technological scheme, have following advantage and and characteristics:
1, tube wall is corrugated structure, under the identical situation of ring stiffness, saves big content of starting materials than solid wall pipe;
2, tubing generally adds other auxiliary agents by high density polyethylene (HDPE) and makes, and light weight is convenient to transportation and is installed;
3, tubing belongs to flexible pipe, and good toughness is shock-resistant;
4, inner tube wall is level and smooth, and under same gradient construction conditions, flow, flow velocity binomial index value all are higher than concrete pipe, thereby can be less than concrete pipe on the tubing specification is selected;
5, have good toughness and plasticity, dry concrete pipe and flexible PVC pipe all can't be by comparison;
6, water tightness is good, adopts steel to mould socket joint connection in the composite elastic sealing, and sewage does not leak outside in can guaranteeing to manage, and can comply with asymmetry settlement of foundation, can not produce the disconnection phenomenon of rupture of concrete pipe.
Description of drawings
The sectional structure schematic representation of Fig. 1 the utility model plastic double walls winding corrugated furnace;
Fig. 2 is the partial enlarged drawing of Fig. 1.
Embodiment
Referring to Fig. 1, Fig. 2, plastic double walls winding corrugated furnace of the present utility model is made of welded connection by the winding of plastics square tube 1 spiral and with hot melt adhesive 2, and the inner side edge of plastics square tube 1 is extended with a minor face 11 to both sides, and the outer side surface of plastics square tube is a fillet for two jiao 12.Hot melt adhesive 2 is connected between the minor face 11 of each adjacent two plastics square tube, forms corrugated pipeline wall.
The structure wall thickness of plastic double walls winding corrugated furnace of the present utility model can be by adjusting the internal mold rotational speed control of forming machine, and spiral angle and roundness can be by adjusting the internal mold angle of swing control of forming machine.
The outer side surface of the plastics square tube in the utility model is a fillet for two jiaos.Than the right angle square tube, tubing groove part backfill is consolidation relatively, avoids causing inhomogeneous power.
Pipeline structure of the present utility model because of with pressure-bearing direction (being generally level or vertical) several angle being arranged, has slowed down pressure to the helix structure that is tilt fixing to a certain extent, compares with the straight burr pipeline of directly extruding, and is not prone to the disconnection phenomenon of rupture.
Below be two embodiments of plastic double walls winding corrugated furnace of the present utility model:
Embodiment 1
Sampling 300SN8 pipeline, internal diameter of the pipeline 294mm, wall thickness 2mm, structure wall thickness 16.5mm.Implementation process is as follows: material is extruded behind the supercooling diameter-setting equipment by extruder, becomes 17 * 17mm square tube, and the internal layer wall thickness is 2mm.Traction is adjusted internal mold angle of swing and speed to Wrapping formed machinery, utilizes the fusion rubber extruding machine to fill hot melt adhesive and cool off simultaneously, thereby forms continuous tubing, and fixed length cutting is also carried out reprocessing.This physical properties of articles is as shown in table 1:
Table 1
Embodiment 2
Sampling 1800SN8 pipeline, internal diameter of the pipeline 1785mm, wall thickness 6mm, structure wall thickness 79.54mm.Implementation process is as follows: material is extruded behind the supercooling diameter-setting equipment by extruder, becomes 82 * 82mm square tube, and the internal layer wall thickness is 6mm.Traction is adjusted internal mold angle of swing and speed to Wrapping formed machinery, utilizes the fusion rubber extruding machine to fill hot melt adhesive and cool off simultaneously, thereby forms continuous tubing, and fixed length cutting is also carried out reprocessing.This physical properties of articles is as shown in table 2:
Table 2
