Utility model works process：
The flexible connection double-bellmouth pipe fitting that the carat pipe of the utility model design is special is used for the company of double socket carat tubing
Connect and use：When connection being installed between tubing and tubing, first load cushion rubber in carat pipe tubing socket end, then carat pipe socket is filled
Enter in bellmouth, because the circle diameter size that the convex tendon top in the middle part of bellmouth inwall is formed is more than the carat pipe spigot of corresponding specification
Outside dimension 2-5mm, so, carat pipe tubing socket by when, convex tendon do not stop tubing socket load, but can to tubing insert
The sealing ring formation extruding that mouthful front end is installed, because the height of convex tendon, width dimensions are smaller, the extruding force to sealing ring is limited,
Final sealing ring by convex tendon and is blocked in bellmouth under external force.
Convex tendon blocks sealing ring in bellmouth, and as tubing socket loads the continuation increase of length, receptacle wall is with holding
Gap between intraoral wall further reduces, the increase of sealing ring decrement, last part elastomeric material deformation, into receptacle wall
The zigzag of design is fallen in groove, enhances sealing effectiveness, while increasing sealing ring to tubing socket ring enclasping force, it is to avoid pipe
Material is deviate from during long-term use from bellmouth.
The special flexible connection double-bellmouth pipe fitting of carat pipe of the utility model design have it is reasonable in design, simple in construction,
The advantages of installing practical and convenient, can meet connection request of the ring stiffness for SN12.5KN/ ㎡ specification carat pipes, and construction letter
Singly, it can be constructed with water, install faster nearly 5 times than hot melt connected mode without special installation apparatus, speed of application.
When tubing is connected with inspection shaft, the socket of the tubing other end can be directly loadable into inspection shaft branch tube faucet, also solved
The problem that carat pipe of having determined is connected with plastic inspection well.
The special flexible connection double-bellmouth pipe fitting of carat pipe of the utility model design, can by PVC, CPVC, HDPE,
The new material obtained after the thermoplastics such as PP, PPB, PB, PET, ABS, or the filling of above-mentioned thermoplastic, blending and modifying, note
Type is moulded into, the advantages of can be with continuous production, mature production technology, relatively low production cost.
It, to explanation of the present utility model, is limited of the present utility model that above-described embodiment, which is, any new to this practicality
Scheme after type simple transformation belongs to protection domain of the present utility model.
