Description

A kind of complex copper is moulded feedwater piping linkage structure and link thereof
Technical field
The invention belongs to water-feeding pipes technical field, be specifically related to a kind of complex copper and mould feedwater piping linkage structure and link thereof.Not only can realize complex copper and mould the hot melt that supply pipe and complex copper mould between connecting piece of water feed pipe and be connected, and can reach between copper liner and closely connect, realize under full copper ring border and supplying water.
Background technique
Complex copper moulds feedwater piping and mating connector is a kind of novel water-feeding pipes, complex copper is moulded feedwater piping and is made up of thin-wall seamless copper liner and outer plastic layer, complex copper is moulded connecting piece of water feed pipe and is comprised two kinds, one is made up of seamless copper liner and outer plastic layer, and one is seamless fine copper link.Conventional P PR supply pipe is easy in-tube fouling and breed bacteria in feedwater process, easy aging distortion in the time of delivery, even separate out plasticizer, complex copper is moulded pipe because the characteristic of copper has solved the problems referred to above, and its high cost performance is by the first-selection that is following feedwater piping.
It is to be all connected by outer layer plastic hot melt with supporting link that current complex copper is moulded feedwater piping, forms crash formula or two kinds of Placements of spigot and socket type between the copper liner of pipeline and pipe fitting.The formula of crashing is the simple docking that copper is moulded liner copper in tube and tube part; Spigot and socket type is that in pipe fitting, liner copper external diameter is slightly less than copper and moulds bore, and in pipe fitting, liner copper inserts copper and moulds in inner tube wall.In connection procedure, the formula of crashing causes the plastics after hot melt to clamp-on joint inwall.ZL200710134690.X has introduced the Placement of a kind of composite plastic metal tube and pipe fitting thereof, and its inner liner metal forms a kind of bayonet joint mode.This technology is that there is a rubber neck at pipe connector place, and rubber neck expands after meeting water, thereby supply pipe can not be leaked.In use, tap water still can touch rubber neck, also easy breed bacteria after prolonged stay.In hot melt connection procedure, copper is moulded pipe and link is heated by the heat melting device of 260 ℃, and rubber neck is difficult to avoid the impact that can be heated, and deterioration by oxidation phenomenon occurs.
Chinese patent 2013202562818 discloses a kind of composite pipe connector component, comprises composite pipe connecting head and conversion adapter, and composite pipe connecting head comprises plastic outer layer pipe and internal lining pipe, and internal lining pipe is provided with the restriction protrusion outstanding to body center; Conversion adapter comprises for inserting large footpath section in composite pipe connecting head and path section for being connected with composite pipe to be connected, between large footpath section and path section, is provided with the transition shoulder for limiting composite pipe insertion depth to be connected.The technical problem that this connector component solves be make to connect convenient, but in sealing, there is certain defect.Because there is certain interval between connecting head, conversion adapter 2 and composite pipe inside and outside wall, although be convenient to like this carrying out of socket joint, but can make to have gap between the inner liner metal of joint, can not accomplish the sealing of metal, and copper is moulded pipe liner copper thickness only for 0.3mm, the processing mode that copper is moulded tube end is cutting, it is inevitable irregular that copper is moulded pipe end metal, copper is moulded pipe end and is difficult to form sealing with conversion adapter place, thereby in feedwater process, there is water and cover contacting of plastics outward, easily causing the secondary pollution of tap water.In addition, the restriction protrusion arranging to body center on the internal lining pipe of connecting head, makes processing become more difficult, and processing cost raises.
