Description
Technical field
The present invention relates to plastic-aluminum combined pipe connected pipe fitting technical field, especially relate to a kind of hot melting and connecting method.
Background technique
Existing aluminium-plastic composite pipe hot melt pipe fitting has two kinds of connecting means, a kind of is outer welding mode, promptly distinguish the skin of heating pipe and the internal layer of hot melt pipe fitting, treat that the laggard row of fusion connects, this mode is not done encapsulation process to the aluminium alloy layer of plastic-aluminum combined tube opening, easily aluminium alloy layer is produced corrosion during line transportation liquid, cause the tubing absciss layer, greatly reduce the Safety performance that pipeline uses;
Another kind of mode is an internal and external layer welding mode, is that the Chinese utility model patent of CN2644848Y promptly discloses this welding mode as notification number.This mode is that pipe fitting joint one end is provided with the birdsmouth between its inside and outside ring wall, and lining is set in the internal ring wall inboard, when socket joint connects, the end of joint birdsmouth and aluminium-plastic composite pipe is heat-treated, aluminium-plastic composite pipe is injected in this birdsmouth then, can make the composite pipe welding in birdsmouth.The hot melt area of this pipe fitting joint birdsmouth is bigger, and it is long to connect length, the isometric hot melt of promptly inside and outside ring wall, and the birdsmouth inwall is indeformable during for guarantee hot melt and insertion, must add metal lining at the interior ring inwall of birdsmouth, has increased the manufacture cost of pipe fitting.Though this mode is carried out encapsulation process to the aluminium alloy layer of plastic-aluminum combined tube opening, easily aluminium alloy layer is produced the problem of corrosion when having overcome line transportation liquid, but it is big that the socket joint of this pipe fitting connects area, hot melt length is long, when pipe is inserted birdsmouth, must form the pressurized air space in the birdsmouth, when the extruding insertion tube period of the day from 11 p.m. to 1 a.m, the birdsmouth insertion end of tube and tube spare has been in the state of being tightly connected, pressurized air in the birdsmouth can't be discharged, certainly lead to empty molten or rosin joint phenomenon, as easy as rolling off a log at hot melt junction surface generation bubble absciss layer, directly reduce the join strength of pipe fitting, simultaneously, birdsmouth in the aforesaid way is actual to become a darker annular blind hole, can't observe pipe and be inserted into end whether arrived at this blind hole bottom when hot melt connects, thereby influence the quality and the intensity of hot melt connection.
Summary of the invention
The purpose of this invention is to provide a kind of hot melt connect reliable, intensity is big, the connecting means of good seal performance, saving material and easy to operate plastic-aluminum combined effective socket pipe piece of heat melted connection.
Technical solution of the present invention is: it may further comprise the steps: heat the internal layer of plastic-aluminum combined tube end and the skin of the internal layer linkage section of skin, socket pipe piece of heat melted connection joint respectively, and the outer shroud inner ring surface of socket joint section and interior ring outer ring surface; Plastic-aluminum combined tube end is inserted in the socket joint section, its internal layer is connected with ring outer ring surface hot melt in the skin of internal layer linkage section and the socket joint section respectively, its skin is connected with the outer shroud inner ring surface hot melt of socket joint section; Observe plastic-aluminum combined tube end by the exhaust peep hole at socket joint section rear portion and whether insert socket joint section bottom.
Because the socket pipe piece of heat melted connection joint is provided with the socket joint section and the internal layer linkage section of order division vertically, between being provided with, the socket joint section forms the outer shroud and the interior ring of annular bell and spigot joint, during connection, ring surface and internal layer linkage section skin are connected with plastic-aluminum combined inner tube layer inner face hot melt respectively in the socket joint section, socket joint section outer shroud inner face is connected with plastic-aluminum combined outer tube layer outermost heat is molten, the pressurized air of sealing up for safekeeping in the hot melt connection procedure in joint socket can in time be discharged by the exhaust observation panel, avoid producing empty molten or rosin joint and produce the phenomenon of bubble separation layer at the hot melt junction surface, it is more tight that aluminium-plastic composite pipe is combined with pipe fitting, and switching performances such as the anti-folding of pipe fitting joint and tensile strength are improved greatly; Can realize that by the exhaust peep hole whether pipe has been inserted the joint socket bottom is observed, thereby improve the operation quality and the join strength of its hot melt attended operation.In addition, because joint internal and external layer weld length difference, be in the outer chain rate socket joint section of socket joint section ring with and the axial length of the internal layer linkage section of isometrical prolongation short, distinguished the primary and secondary junction surface of joint, main junction surface is to bear the main stress surface that pipe fitting connects, and inferior junction surface is only born the task of the aluminium alloy layer of plastic-aluminum combined tube opening being carried out encapsulation process, and is long as it, not only increase cost of material, also owing to not outstanding main junction surface reduces whole join strength; Simultaneously, connect area owing to can effectively reduce hot melt, the heating-up temperature of control connection face easily guarantees that when heating ring is indeformable in the pipe fitting, increases metal lining thereby need not encircle inwall in joint socket, saving tube material cost and cost of production.
As a kind of optimized project, the internal layer of described plastic-aluminum combined tube end uses direct way of contact heating, the outer radoal heating mode of using heats, use direct rate of heating very fast, fusion penetration is big, connect the back in conjunction with tightr, and, use the heat-fusing glue layer between survivable outer layer plastic of radoal heating and the middle aluminium lamination because the skin of aluminium-plastic composite pipe is thinner usually.
The interior ring outer ring surface of the skin of described internal layer linkage section and described socket joint section uses direct way of contact heating, and the outer shroud inner ring surface of described socket joint section uses the radoal heating mode to heat; Use direct rate of heating very fast, fusion penetration is big, guarantees to connect the main junction surface in back in conjunction with tightr, uses radoal heating outer shroud inner ring surface, prevents because of overheated melting deformation, causes operation inconvenience.
Advantage of the present invention is: solved the exhausting problem that is produced when aluminium-plastic composite pipe is connected with the pipe fitting hot melt fully, improved hot melt and connect operation quality, improved reliability, sealing and join strength that its hot melt connects greatly, economical with materials, processing ease.
