Abstract
The invention discloses a method for connecting plastic pipes, comprising the following steps that 1) a first plastic pipe is fetched as a main pipe and a second plastic pipe is fetched as a branch pipe; the diameter of the main pipe is at least 12mm and the diameter of the branch pipe is at least 2mm; the wall of the main pipe is provided with a hole with the same internal diameter as that of the branch pipe; 2) the edges of the main pipe hole and the branch pipe opening is heated to 200 to 300 DEG. C in the pattern of thermal fusion; 3) when the edges of the main pipe hole and the branch pipe opening is melting, the branch pipe opening and the main pipe hole are connected in a sealing way to cool and set under room temperature naturally. The invention is suitable for connecting pipes made of thermal plastic materials which can be molded by thermal fusion such as polypropylene, heat-resistant polythene, polybutene, etc.; after being connected, the plastic pipes can be processed into reticular pipe with even distribution and little loss of water power; therefore, the invention can be used widely in fields such as heating ventilation air conditioner, water supply and drainage, and the like and can be beneficial to be popularized and implemented.
Description
Technical field
The present invention relates to a kind of method of attachment of plastic conduit, especially a kind of method of attachment that is used for the plastic conduit in fields such as HVAC or plumbing.
Background technology
In fields such as HVAC or plumbing, the application of plastic conduit more and more widely.Connection between existing two plastic conduits, be connected the use that the pipeline that aforementioned connected mode has limited 1 integral body and at least 3 pipelines are connected simultaneously between the port that normally adopts plastic conduit and port with hot melt, gluing or mechanical system by connecting tubes such as straight-through, elbow, threeways.The used pipe fitting of the connected mode of conventional plastic pipeline is many, connects complex process, and leakage accident takes place easily.Particularly, must not be according to the thermoplastic pipeline wall thickness that existing national standard " the general wall thickness table of GB10798-89 thermoplastic plastic pipe " and " JBJ ground radiation heating technical regulation B.1.3 " regulation are connected with hot melting way less than 1.9mm, could guarantee the reliability that hot melt connects, but so just limited of the development of the plastic conduit of hot melt to little caliber and small caliber direction, the wall thickness of small-caliber pipeline can be considerably beyond the wall thickness requirement of satisfying required pressure rating, not only cause raw-material waste, the excessive pliability that also reduces plastic pipe of wall thickness has increased installing space.
Summary of the invention
In order to solve the limitation of above-mentioned existing thermoplastic plastic pipe interconnection technique, the object of the present invention is to provide to add traditional connecting tubes such as straight-through, elbow, threeway between a kind of plastic conduit, can realize the method for attachment of plastic conduit port and the direct-connected plastic conduit of port.
To achieve these goals, the present invention adopts following technical scheme: a kind of method of attachment of plastic conduit, it comprises the steps: 1) get first plastic conduit and be responsible for, get second plastic conduit and make arm; The described person in charge's caliber is at least 12mm, and the caliber of described arm is at least 2mm, offers a hole on this person in charge's tube wall, and the size of this hole diameter is identical with the internal diameter of described arm; 2) with hot melting way step 1) is responsible for hole edge and the arm mouth of pipe edge offered and is heated to 200-300 ℃; 3) in step 2) in person in charge's hole edge and arm mouth of pipe edge when being in molten condition, with docking mode the arm mouth of pipe is tightly connected with being responsible for hole, place nature cooling and shaping under the room temperature then.
Above-mentioned person in charge's caliber is 12mm-150mm, and its wall thickness is 2mm-12mm, and this person in charge's length is 100mm-6000mm.
Above-mentioned branch diameter is 2mm-25mm, and the pipe thickness of this arm is 0.3mm-3.5mm, and length is 20mm-30000mm.
Be responsible for hole and prop up being connected of pipe port for better fixing, in above-mentioned steps 1) person in charge's hole and pipe port between can also press from both sides and establish one and strengthen pad, strengthening pad 3 is annular gasket, also can be two semicircular pads, through step 2) the high temperature hot melt after, this strengthens the one side and the welding of described person in charge's hole of pad, another side and described pipe port welding; Realization will be responsible for hole, strengthen pad and prop up a pipe port welding is one.
In order to guarantee that being responsible for hole has the best effect that is connected with a pipe port, tie point is firm, good sealing effect, and the used person in charge's material of the present invention must be identical material with the arm material; When needs use to be strengthened pad, this material of strengthening pad also must be identical with the material of the person in charge and arm, all can adopt PP (polypropylene), PE-RT (heat-proof polythene), PB (polybutene) to be equal to connection between the pipeline of analog thermoplastic plastic material; Strengthen to play good fixation to being responsible for behind the pad hot melt by using with the docking site of arm.
The restriction that pipeline is not subjected to wall thickness of propping up of end face is provided in connection, and wall thickness can still guarantee the solid and reliable of tie point in 0.3-1.2mm scope.
The present invention has broken through between the plastic conduit by pipe fitting and has realized end and hold the traditional connected mode that is connected and the restriction of wall thickness, end face with a pipeline is connected with the direct hot melt in the side of another pipeline, play fixation by butt joint after strengthening the pad hot melt with material, tie point is very solid and reliable, and pipeline connects the back and realizes integrated.Can manufacture incorporate plastic tube network to plastic conduit easily by this plastic conduit method of attachment, this plastic tube network water distribution is even, reduces resistance, satisfies the application in HVAC or plumbing field better, being responsible in the particularly this pipe network can be thick, and draining is unobstructed; Arm can be thin, the thinnest 2mm that is made as, and wall thickness is the thinnest can be to 0.3mm, has exceeded branch diameter in the existing HVAC technology and has been not less than the regulation that 12mm, pipe thickness can not be thinner than 1.9mm; Thin like this arm can be provided with a lot of roots, and is parallel and be arranged side by side, if two ports of every arm adopt aforementioned hot melting way to be connected with a plurality of holes that the same straight line of two person in charges' sidewall is offered respectively, may be molded to diversity ability of swimming plastic tube network.This diversity ability of swimming plastic tube network syndeton novelty, connect reliable, waterpower and be evenly distributed, hydraulic loss is little, low cost of manufacture, can be widely used in a plurality of fields such as HVAC or plumbing, has very big promotion and implementation and is worth.
