Further reduced inner diameter, to the lateral wall of wall embeded on the inside of its madial wall meeting banding, plastic material is with metal material at this
Connection on face is also even closer, and leak resistance can also be promoted；The technical solution of the utility model in summary, hot and cold water are logical
With, can effectively prevent pipe fitting PPR plastics longterm expansion shrink after seepy question, be a kind of high performance PPR pipe part.
The axial length of the outside wall embeded is longer than the axial length of inside wall embeded.Keep connection more firm.
The lower end of the medial surface of the outside wall embeded is equipped with lug boss.Keep connection more firm.
The boss is under the lower face of inside wall embeded.The filling that material in gap is filled when injection molding is not interfered,
If being arranged in filling gap, the intensity of injection-moulded plastic in filling gap is easily reduced.
On the inside wall embeded and/or outside wall embeded also uneven distribution have it is several for being injection molding material after injection molding
Expect the through hole of filling.Keep connection more firm.
The utility model has the beneficial effects that：A kind of high-performance PPR pipe part of the utility model, metal insert connector
For to there is the inside wall embeded being integrally connected and outside wall embeded, inside wall embeded and outside wall embeded with one end of pipe main body injection molding connection
Between there is filling gap, the injected plastics material of pipe main body is filled in filling gap, it is in the actual use process, heated
When, the material thermal expansion coefficients that pipe main body is filled in filling gap are bigger than metal, cause to fill the plastics material in gap
Material expansion jam-packed medial and lateral wall embeded, contact is even closer, and sealing performance is more preferable；When being cooled, plastic conduit is shunk, and fills gap
The further reduced inner diameter of meeting after interior plastic material is shunk, to the lateral wall of wall embeded on the inside of its madial wall meeting banding, plastics
Material and connection of the metal material on this face are also even closer, and leak resistance can also be promoted；The utility model in summary
Technical solution, hot and cold water is general, can effectively prevent pipe fitting PPR plastics longterm expansion shrink after seepy question, be a kind of
High performance PPR pipe part.
