Abstract
The utility model relates to a kind of fitting structure fuses of modified hot melt interconnection technique, which is characterized in that fuse overall structure is at T-shaped, T-shaped top is consistent with the mean outside diameter of tubing, with a thickness of 3-5mm, T-shaped lower part is consistent with the internal diameter of tubing, wall thickness 3-5mm；T-shaped centre is cylindrical hollow configuration, and internal diameter is approximately less than pipe internal diameter 6-10mm.The technology main advantage is to solve the problem of that metal layer does not seal when composite metal-plastic pipe connection, and secondly common plastics pipe fitting can be used for the connection of composite metal-plastic pipe.
Description
Technical field
The utility model relates to hot-melt adhesive paste technical fields, specifically, being a kind of pipe of modified hot melt interconnection technique
Part structure fuse.
Background technique
In building in hot and cold water water supply system or cooling fin heating system, the use of plastic conduit occupies higher city
Market share, but plastic conduit also exposes some problems in later period application process.Such as in high-temperature field pressure resistance deficiency or low temperature
Brittleness is larger, the accidents such as leak, rupture occurs and occurs often.Because both having, plastic conduit is good to be defended composite metal-plastic pipes
Natural disposition energy and hot melt connectivity, and intensity and rigidity with metallic conduit, so that being used in some high-temperature fields
It is more and more.In use, an important key point is can whether the connection of tubing and pipe fitting be reliable, guarantee to pipeline
The normal operation in later period.The connection of composite metal-plastic pipes is broadly divided into two kinds currently on the market: one is use commonly
Plastic pipe and the direct hot-melt adhesive paste of composite metal-plastic pipes, do not seal in weld metal layer, thus there is one
Hidden danger of quality constantly washes away metal layer in later period hot water use process, will lead to the corrosion of metal layer, and then metal layer
It is layered with plastic layer.Another connection type are as follows: a kind of double hot melt structures are used, by metal layer in hot-melt adhesive paste, sealing
Get up.But because tubing specification is different, the product of different wall thickness needs different fitting structures, and required mold is just very more, it is single
Secondary investment is just very high.
Utility model content
The purpose of the utility model is to overcome the deficiencies in the prior art, provide a kind of pipe of modified hot melt interconnection technique
Part structure fuse.
The purpose of this utility model is achieved through the following technical solutions:
A kind of fitting structure fuse of modified hot melt interconnection technique, which is characterized in that fuse overall structure is at " T " word
Shape, T-shaped top is consistent with the mean outside diameter of tubing, with a thickness of 3-5mm, the internal diameter one of T-shaped lower part and tubing
It causes, wall thickness 3-5mm.Guarantee that fuse can be inserted inside tubing.
T-shaped centre is cylindrical hollow configuration, and internal diameter is approximately less than pipe internal diameter 6-10mm.
The T-shaped wedge shaped structure of lowest part, convenient for the insertion of fuse.
The fitting structure fuse carries out injection molding using the material with plastic composite pipe plastic layer same material.
The material such as PE of plastic composite pipe plastic layer same material, PPR material.
Fuse is inserted into inside tubing by a kind of novel fitting structure fuse in hot-melt adhesive paste, multiple for blocking plastics
The plastic layer of the metal layer of conjunction pipe, fuse and tubing is material of the same race, guarantees the two in the reliability of later period hot-melt adhesive paste.The skill
When art hot-melt adhesive paste, a kind of required dedicated hot melt mold, mold one end for fuse and tubing to be fused into one, mold it is another
Tubing and pipe fitting, are then connected as one by one end hot melt pipe fitting.
The technology is related to a kind of dedicated hot-melt adhesive paste mold, and mold cavity block end is in convex groove type structure, and formpiston is at convex shape.
In hot-melt adhesive paste, after fuse is inserted into tubing inside, insertion mold cavity block band that end of tongue, pipe fitting is inserted into mold
Formpiston end, with after heating melting, the two directly carries out hot-melt adhesive paste.
Compared with prior art, the good effect of the utility model is:
The technology main advantage is to solve the problem of that metal layer does not seal when composite metal-plastic pipe connection, secondly
Only need to develop a matched core structures, common plastics pipe fitting can be used for the connection of composite metal-plastic pipe, have
Certain application value.

Specific embodiment
A kind of specific embodiment of the fitting structure fuse of modified hot melt interconnection technique of the utility model presented below.
Embodiment 1
Refer to attached drawing 1,2,3,4,5, a kind of fitting structure fuse of modified hot melt interconnection technique, which is characterized in that
For fuse overall structure at T-shaped, T-shaped top is consistent with the mean outside diameter of tubing, with a thickness of 3-5mm, T-shaped lower part
It is consistent with the internal diameter of tubing, wall thickness 3-5mm.Guarantee that fuse can be inserted inside tubing.
T-shaped centre is cylindrical hollow configuration, and internal diameter is approximately less than pipe internal diameter 6-10mm.
The T-shaped wedge shaped structure of lowest part, convenient for the insertion of fuse.
The fitting structure fuse carries out injection molding using the material with plastic composite pipe plastic layer same material.
A kind of modified heats interconnection technique, in pipeline connection, first fuse is inserted into inside tubing, then by the two one
With insertion mold former, at the same time pipe fitting insertion mold formpiston, heated, after plastics at molten condition after, stand
Tubing and pipe fitting are removed simultaneously above matched molds, tubing is inserted into inside pipe fitting without spin rapidly, makes joint
Form homogeneous flange.The connector just completed should be avoided by external force, and band natural cooling rear can be use.
The above is only the preferred embodiment of the utility model, it is noted that for the common skill of the art
Art personnel can also make several improvements and modifications without departing from the concept of the premise utility, these improvements and modifications
Also it should be regarded as in the protection scope of the utility model.
