Description
Technical field
The present invention relates to hot-melt adhesive paste technical fields, specifically, being a kind of pipe fitting knot of modified hot melt interconnection technique
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.
Summary of the invention
It is an object of the invention to overcome the deficiencies of the prior art and provide a kind of pipe fitting knots of modified hot melt interconnection technique
Structure fuse.
The purpose of the present invention 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
