Abstract
The utility model discloses a metal and plastic composite pipe connecting device, consisting of two metal and plastic composite pipes which are in butting connection mutually. A middle metal layer on the end surface of each metal and plastic composite pipe is shorter than internal and external plastic layers, the middle layer is a metal layer of the pipe end surface stripped by a stripper, and then the metal layer of the end surface of each metal and plastic composite pipe is coated by the internal and external plastic layers via a cavity of a special fuse machine and can not contact with fluid delivered by the pipes. By aid of the metal and plastic composite pipe connecting device, a common plastic pipe fitting and a welded composite pipe fitting can be in hot melting connection. The metal and plastic composite pipe connecting device is adaptable to connection of metal and plastic composite pipes.
Description
Technical field
The utility model relates to a kind of composite metal-plastic pipe connection set.
Background technique
The use of welded-connecting type composite metal-plastic pipe is very extensive, every field such as use all to use in industrial and agricultural production, medication chemistry, construction engineering and Family Day, traditional composite metal-plastic pipe Placement is to adopt pipe fitting end to be cut flat, connects with the heat melting device fusion and to form.The pipeline that this mode connects is in long its using process, because the metal layer in the middle of it exposes easily, the water that process is long-term or the corrosion of other media, or oxidation in air connect partly and damage and leakage or gas leakage easily.
Summary of the invention
The purpose of this utility model is the shortcoming at the incidental leakage of above-mentioned composite metal-plastic pipe link, provides a kind of reasonable in design, the simple composite metal-plastic pipe link of method device.
In order to achieve the above object, the utility model is mainly finished by the following technical solutions.The utility model mainly is made up of two composite metal-plastic pipes that dock mutually, the intermediate metal layer of the end face of described composite metal-plastic pipe is shorter than interior outer plastic layer, described mesosphere is a metal layer of peelling off the pipe end face by detacher, pass through the die of special-purpose heat melting device again, the metal layer of composite metal-plastic pipe end face is coated by interior outer plastic layer, the metal layer of tubing is not contacted with the fluid of line transportation.Common plastic pipe can be connected with welded-connecting type composite pipe hot melt.
The utility model compared with prior art has following tangible advantage.(1) simple in structure, easy to operate.The utility model adopts the metal intermediate layer of composite metal-plastic pipe end is peelled off some millimeters technology by detacher, again by the die of the heat melting device of special use, the metal layer of end face that can make composite metal-plastic pipe is by inside and outside plastic overmold, the metal layer of tubing is not contacted with the fluid of line transportation, not only solved the problem that metal layer is corroded, prevented that more effectively high-pressure liquid from entering the composite bed of plastics and metal by tube end face, thereby the destruction pipe performance uses the pipeline long-term safety by such hot melt connection.(2) alleviate cost.The utility model can be connected common plastic pipe with welded-connecting type composite pipe hot melt, can reduce the use amount of noble metal pipe fitting, reduces manufacture cost and user cost.
The utility model is applicable to the connection of composite metal-plastic pipe.
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Description of drawings
Accompanying drawing is the utility model overall structure cut-away view.
Embodiment
As shown in the figure, the utility model mainly is made up of two 1,8 of composite metal-plastic pipes that dock mutually, the intermediate metal layer 3,6 of the end face of described composite metal-plastic pipe 1,8 is than interior outer plastic layer 2,4 and 5,7 weak points, the metal layer 3,6 of composite metal-plastic pipe 1,8 end faces is coated by interior outer plastic layer 2,4 and 5,7, and the metal layer of tubing is not contacted with the fluid of line transportation.Common plastic pipe can be connected with welded-connecting type composite pipe hot melt.
The utility model is applicable to the connection of composite metal-plastic pipe.
Claims (1)
1. composite metal-plastic pipe connection set, formed by two composite metal-plastic pipes that dock mutually, the intermediate metal layer that it is characterized in that the end face of described composite metal-plastic pipe is all lacked than interior outer plastic layer, and the intermediate metal layer of composite metal-plastic pipe end face is coated by interior outer plastic layer respectively.
