Description
Technical field
The utility model is related in the middle of one kind be metal or nonmetallic layers of reinforcement that inside and outside layer is multiple for thermoplastic
The steel-plastic composite pressure pipe road two-sided electric melting pipe fittings of multiple tube that layer is constituted are closed, belongs to the connecting pipe manufacture of composite pressure pipeline
Field.
Background technology
In existing patent publication us, there are many on the installation pipe fitting of MULTILAYER COMPOSITE pressure pipeline and connection method
Open source literature, the publication mainly has clamp-press type pipe, using mechanical fasteners connected mode；Flange type pipe fitting, using pipe
End enlarging, flange form is fastenedly connected；Two-sided hot melt pipe fitting, using electrical heating tool first by the ectonexine plastics and pipe of compound pipeline complex pipeline
The installation composition surface of part is heated simultaneously, then, tubing quickly is inserted into pipe fitting hot-melt adhesive paste；The double hot melt pipe fittings of electromagnetic welding direct type,
Similar to Double-side hot fusion tube part, connection method is that tubing first is inserted into pipe fitting to pipe fitting, is generated heat using electromagnetic induction intermediate layer pipe steel,
And conducting heat makes tubing ectonexine plastics be closed with the composition surface plastic hot melt of pipe fitting.
The installation pipe fitting and connected mode of the above multiple tube, come with some shortcomings, mechanical fasteners connection, flange form
Pipe fitting is fastenedly connected, using strong pressure pipe end（Flange form uses enlarging）Plastics are simultaneously carried out close using rubber seal
The mode of envelope, deficiency is easily aging rubber seal, and the deformation of composition surface plastic continuing, loosening influence sealing property；Double-side hot
Fusion tube part, is closed with pipe fitting composition surface plastic hot melt using compound pipeline complex pipeline ectonexine and is connected, and bonding strength and sealing property are preferable, but
Be, by the way of the composition surface of electrical heating tool heating pipe and pipe fitting respectively simultaneously is inserted into welding, exist to pipeline and
Pipe fitting must be while heated to plastic molten melt state, and heating requirements are high, and influence factor is more, is possible to peel off during pipeline insertion pipe fitting
Inside and outside melting layer plastics, cause line clogging or heat seal strength not enough, install attended operation difficulty larger.It is molten using electromagnetic induction
The mounting means for connecing, is the birdsmouth that pipeline is first inserted pipe fitting, is then heated with electromagnetic induction heating specific purpose tool, is made
Middle steel pipe layer heating, is transmitted to plastic layer and pipe fitting composition surface, pipeline is integrated with the fusion of pipe fitting composition surface；Its deficiency exists
Very high in requiring pipeline and pipe fitting quality of fit, plastic extrusion, the size of injection molding are extremely difficult to or dimensional accuracy is unstable
Fixed, influence is installed and coordinated, and secondly, is generated heat with electromagnetic induction steel pipe, and conduction heating plastics, heating temperature of steel pipe is too high, multiple tube
The local reheating in road, may have an impact to steel pipe with the compound sticking intensity of plastics, especially install fit clearance mistake
Greatly, the heat time it is long in the case of, have considerable influence to the bonding strength of pipeline and pipe fitting.

Steel（Aluminium, copper, stainless steel）Composite metal plastic pipe end face, prevents from being collided with the outer electric melting pipe fittings step end face heating wire of sleeve pipe, occurs short
Road（Intermediate layer is nonmetallic enhancement layer, without this pad）；The endoporus of the outer electric melting pipe fittings of sleeve pipe is preset with bushing（Stainless steel or
Copper）, injection molding deformation is reduced, machining accuracy is improved, outer cylinder surface and step end face lay heating wire, in the two ends of heating wire
Connection plug-in joint, joint is externally provided with joint protective sleeve, for external power supply equipment, gives heating wire electrified regulation.
Technical scheme：A kind of two-sided electric melting pipe fittings of multiple tube, pipe fitting is combined using split type electric melting pipe fittings, by sleeve
The outer electric melting pipe fittings composition of electric melting pipe fittings, pad, sleeve pipe；Heating wire is laid in its middle sleeve in electric melting pipe fittings hole, in heating wire
Two ends connect plug-in joint, and joint is externally provided with joint protective sleeve, and the endoporus of the outer electric melting pipe fittings of sleeve pipe is preset with bushing.
Compared with background technology, one is multiple tube to the utility model and pipe fitting welding is an entirety, installs connection reliability,
Good airproof performance；Two be split type two-sided electric melting pipe fittings installation connection it is simple, directly fused installation faying face, efficiency high, to peace
Dress personnel's technical requirements are not high, standard operation, installation quality reliability；Three is pipeline and pipe fitting body same material phase welding, no
Using potted components such as rubber seal, the same life-span is used with pipeline；Four is that the inside and outside dimensional accuracy of multiple tube and pipe fitting are coordinated
Dimension precision requirement is not high；Five is direct electric smelting plastic layer, is allowed to fuse, and the middle enhancement layer to pipeline is compound with plastic layer
Intensity does not influence substantially.
