Abstract
The utility model discloses a steel wire skeleton plastic electric hot-melt connecting pipe forpolyethylene composite pipes. The electric hot-melt connecting pipe comprises a plastic pipe layer, an electric hot-melt interface, heat-emitting resistance wires, a binding adhesive layer and a fastening layer, wherein the heat-emitting resistance wires are arranged at the inner side of the plastic pipe layer; the fastening layer is arranged at the outer side of the plastic pipe layer; the electric hot-melt interface is connected with the heat-emitting resistance wire; and the binding adhesive layer is arranged at the inner side of the heat-emitting resistance wires. An electric hot-melt method and the fastening layer are adopted in the electric hot-melt connecting pipe, the firmness of a pipeline formed by connecting the polyethylene composite pipes is greatly improved, and meanwhile, and the service life of the pipeline after connecting is improved.
Description
Technical field
The utility model belongs to the pipeline connection area, especially relates to the molten connecting tube of a kind of steel wire mesh frame plastic polyethylene compound pipe electric heating.
Background technique
Polyethylene compound pipe is that the polyethylene resin with two kinds of different densities processes, so it has two kinds of Material Characteristics concurrently, because the resistance to pressure and the corrosion resistance of polyethylene compound pipe are all good than common polythene pipe; So in industrial and mining enterprise; Often adopt this polyethylene compound pipe to replace steel pipe, be used for the delivery pipe or the mine ventilation pipeline of the media that are corrosive such as oil, coal gas, in long-term practice process; Often need connect two joint polyethylene compound pipes; In traditional connecting means, adopt the method that compass connects mostly, this connecting means exists some defectives that can't overcome; Such as: one, the sealing between the connection pipe fitting is poor, is difficult to guarantee do not have defective between the connection pipe fitting; Two, connection procedure is complicated, at first need guarantee the coaxality between the connection pipe fitting, and only under the prerequisite that guarantees coaxality, can guarantee does not have the slit between the connecting tube.
Summary of the invention
The technical problem that the utility model will solve is: existing polyethylene compound pipe connecting tube is improved, provide a kind of simple in structure, connect the molten connecting tube of steel wire mesh frame plastic polyethylene compound pipe electric heating firm, easy-to-operat.
For solving the problems of the technologies described above, the technological scheme that the utility model adopts is: steel wire mesh frame plastic polyethylene compound pipe electric heating melts connecting tube, comprises plastic pipe layer, electric heat welding mouth and heating resistance wire; Also comprise bonding glue-line and fastened layer, said plastic pipe layer inboard is provided with heating resistance wire, and the said plastic pipe layer outside is provided with fastened layer, and said electric heat welding mouth is connected with said heating resistance wire, and said heating resistance wire inboard is provided with bonding glue-line.
As optimal technical scheme, the utility model has also adopted following technical characteristics:
Said bonding glue-line inboard is provided with and is used for positioning boss that connected tube is positioned.
Said electric heat welding mouth is located at the sidewall of plastic pipe layer.
Said electric heat welding mouth is located on the end face of plastic pipe layer.
Advantage and the good effect that the utlity model has are: one, adopt thermoelectric molten connection pipe fitting, be very easy to operating process; Two, set up fastened layer through the outside, prevented connecting tube because expand with heat and contract with cold former thereby bring and connect unsettled defective at plastic pipe layer; Three,, greatly improved the fastness after pipeline connects through bonding glue-line being set in the heating resistance wire inboard; Four, through boss being set, can guarantee the connection bondability of connecting tube well at bonding glue-line.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Among the figure: 1, plastic pipe layer; 2, electric heat welding mouth; 3, fastened layer; 4, heating resistance wire; 5, bonding glue-line; 6, positioning boss.
Embodiment
As shown in Figure 1; The technological scheme that this specific embodiment adopts is: steel wire mesh frame plastic polyethylene compound pipe electric heating melts connecting tube; Comprise plastic pipe layer 1, electric heat welding mouth 2, heating resistance wire 4, bonding glue-line 5 and fastened layer 3, said plastic pipe layer 1 inboard is provided with heating resistance wire 4, and said plastic pipe layer 1 outside is provided with fastened layer 3; Said electric heat welding mouth 2 is connected with said heating resistance wire 4, and said heating resistance wire 4 inboards are provided with bonding glue-line 5; Said bonding glue-line 5 inboards are provided with and are used for positioning boss 6 that connected tube is positioned; Said electric heat welding mouth 2 is located at the sidewall of plastic pipe layer 1.
More than the embodiment of the utility model is specified, but said content is merely the preferred embodiment of the utility model, can not be considered to be used to limit the practical range of the utility model.All equalizations of doing according to the utility model application range change and improve etc., all should still belong within the patent covering scope of the utility model.
