Description
Technical field:
The utility model relates to a kind of metal framework reinforced plastic composite pipe network.
Background technique:
Being connected with the mechanical snap method between the plastic tube of known metal composite connects, as aluminium-plastic composite pipe, the electrical heating wire electric heating tubing that useful pipe connecting component joint socket inner chamber distributes is connected the two sides fusion with the cylindricality junction surface or the tapering junction surface of pipe fitting, also utilize spin friction to give birth to the method for heat fusing connection with the method for the conical surface between tubing and the pipe fitting together with the step end face heat fusing connection of tube intracavity just like number of patent application 200510021077.8, also just like number of patent application 03225501, this patent disclosure be a kind of aluminium-plastic composite pipe hot melt linkage structure, in addition also just like number of patent application 200510022348.1, this patent disclosure be a kind ofly " to lay respectively in the metal frame; the outer inner plastic of one deck at least tube wall tilted conical surface; one deck plastic outer layer tube wall tilted conical surface at least, adopt heat fusing heating resistance collar and glow plug respectively they to be added thermal recovery thermofusible spigot method between the inner conical surface of each tilted conical surface and plastic pipe joint socket and be connected to pipe network.”
In the above-mentioned known technology, use the mechanical snap method, can not give full play to the characteristics that pipe connecting member of plastics material can be tightly connected with metal composite plastic tube hot melt, can not prevent effectively that the pipe network fluid from strengthening the corrosion of skeleton to the metal in the composite pipe.
Electric heating wire heating and melting tubing and pipe fitting junction surface with the distribution of pipe connecting member of plastics material joint socket inner chamber, because of adding silk, electricity can only distribute at outer wall or tube intracavity, can not utilize plastics melting sealed between the ring-shaped step with tubing end and tube intracavity design, strengthen the corrosion of the sealing of skeleton and fluid so can not solve the metal of the metal composite pipe of the pipe network that connects to it, though taked to utilize plastic hoop to come sealing metal to strengthen skeleton plastic outer layer in the tube end face heating and melting connection skeleton in advance, but coefficient is different because metal and two kinds of material hot lines of plastics expand, plastic pipe electric heating melts when connecting, the cooling that reality is different because of line expands or welding is later is shunk different, plastic outer layer reality has order of magnitude difference because of linear expansion in plastic hoop and the metal frame, the reason of expanding with heat and contract with cold causes skeleton to withstand plastic hoop, produces the crack between the two and does not reach seal request.
(application number 200510021077.8) of the applicant's application utilizes the welding of spin friction heat fusing, this technology provides a kind of pipe end flange of steel-frame reinforced composite plastic pipe, pipe end flange is made up of with a plastics flange that is connected with end face spin friction heating and melting with the outer cone surface of multiple tube or pipe fitting end plastic composition pipeline or pipe fitting that Steel Skeleton strengthens, this flange has an inwall that is tapering and a step surface that is connected with the end face fusion of multiple tube or pipe fitting that matches with the tapering on multiple tube or pipe fitting outer cone surface, the outer cone surface of this inwall and step surface and multiple tube or pipe fitting contacts with end face and when producing spin friction, their contact friction face Yin Shengre and fusion, the smelt that produces couples together the outer cone surface and the fusion of pipe end face of flange inner wall and step end face and multiple tube and pipe fitting, make plastics flange become the pipe end flange that nonvolatil fusion is connected with multiple tube or pipe fitting, the pipe end flange hot melt of this pipeline or pipe fitting docks just can connect and is pipe network, this technology has realized better seal to the enhancing Steel Skeleton of pipeline or pipe fitting, solved the connection sealing difficult problem in metal enhancing framework composite tube road, this spin friction utilizes the fusion of the conical surface and end face to be connected, though preferably resolve the sealing of metal frame, but it is more at the complicated pipe fitting that need connect of design of pipe networks, when type is complicated, when being connected of more vertical with horizontal solid particularly arranged, only depend on and utilize spin friction melting tube end flange on pipeline or the pipe fitting, and with pipe end flange again hot melt to form pipe network be to be inconvenient to rotate to fetching.When networking, have vertically especially or when laterally connecting, or when being welded to form a net or arm, can't rotate the frictional heat welding.This method is than major diameter, on ground or bury when the ground straight tube connects abundant advantage is arranged, in connecting building and in the plane, sub-district or the less difficulty that has the rotation inconvenience when φ 200 is following of main body pipe network or diameter.
As number of patent application 200510022348.1, the pipe network that this invention metal composite plastic tube is connected with plastic pipe, there is coniform joint socket the plastic pipe termination, the metal frame mesosphere is arranged in the metal composite plastic tube, in the metal frame mesosphere, at least one deck plastic layer is arranged respectively on the outer wall, there is the cone that cooperates with the coniform joint socket of plastic pipe metal composite plastic tube termination, inner plastic tube wall end face is arranged on the cone, the metal frame tilted conical surface that cooperates with the joint socket inner conical surface, lay respectively in the metal frame, the outer inner plastic of one deck at least tube wall tilted conical surface, at least one deck plastic outer layer tube wall tilted conical surface adopts heat fusing heating resistance collar and glow plug respectively they to be added thermal recovery thermofusible spigot method and is connected to pipe network between the inner conical surface of each tilted conical surface and plastic pipe joint socket.Because of tube wall and pipe joint inner cavity surface all are conical surfaces, heat fusing body when heating the back socket joint each other on the conical surface of correspondence is because of extruding rather than push out junction surface, enough melts are not only arranged, enough pressure is also arranged, welding is good each other, but still exist the metal frame of pipeline end face to be connected weak link with the plastic pipe termination with inner plastic, particularly the metal composite plastic tube is applied under the abominable occasion of environment, as delivery, but coefficient has order of magnitude difference because metal and two kinds of material hot lines of plastics expand, cold and heat succeed each other for a long time, the generation crack does not reach seal request between the two because of the reason of expanding with heat and contract with cold causes to connect weak link place's plastics and metal frame.
Summary of the invention:
In view of above reason, the purpose of this utility model is in order to overcome above deficiency, to provide a kind of multiple tube that makes to be connected firmly, the metal framework reinforced plastic composite pipe network of seam crossing mechanical strength height, nothing leakage, pipeline long service life.
