It is inserted directly into bellmouth and completes installation.It is more quick and convenient compared to electric fusion welding, for need rapid construction region can it is quick,
Efficiently accomplish.
The internal diameter of the bellmouth joint is adapted with the outside dimension of the socket connector.Ensure bell and spigot joint in caliber chi
On very little, socket joint operation can be achieved on.
Further, the periphery of the sealing ring is also integrally formed with non-return alar part, and the section of the non-return alar part is wedge
Point to the port of the socket connector in shape, the front end of the wedge-shaped non-return alar part.Wedge-shaped non-return Fin structures it is enhanced close
Seal structure design, in grafting bell and spigot joint, when ensureing enough sealing effectiveness, if certain when occurring in practical set
The tubing stress of amplitude and retract, can effectively rely on the wedge-type seal coil structures, play enough non-return effects, and sealing effect
It is really unaffected.
Further, it is the intensity of improvement bell and spigot joint, the pipe thickness of the socket connector is more than the pipe of the body
Wall thickness.
Further, wedge-shaped non-return alar part being radially arranged to be multiple along the socket connector of the sealing ring.
Further, the material of the sealing ring is neoprene, and neoprene has extremely strong corrosion-resistant and resistance to compression
Contracting tensile property, is suitable for the sealing in bell and spigot joint.
Further, the corner cambered of the corner portion of bellmouth joint is 135-165 °.It is highly dense in this corner cambered scope
Spending polyethylene (HDPE) tubing has most strong bearing strength, is conducive to tubing bell and spigot joint and the pressure-bearing of tubing body to be connected.
Further, the position of the sealing ring being set on socket connector outer wall is arranged in the bellmouth joint
The front end of electric heating fuse on wall.In this way, when assembling, energization fused inner is completed after the gap sealing of connection-peg, and sealing ring can
Play it is certain prevent the cracking at fuse welding position, play auxiliary humidification.
Integrally formed HDPE hollow spiral tubes of a kind of bell and spigot joint that the present invention is provided have the beneficial effect that：
There is provided a kind of bell and spigot joint one for the technical problem for the tubing fitting joint that the present invention exists for above-mentioned prior art
Body formed HDPE hollow spiral tubes, realize tubing without carrying out single connection-peg docking behaviour to it when engineering is installed
Make, core is intended to improvement and realizes that bell and spigot joint can also realize sealing ring and electric smelting dual fail-safe type of attachment, that is, installs glue
The socket of circle, which is inserted, reloads alternating current progress electric fusion welding after the bellmouth joint, electric heating is increased behind rubber sealing face
Fusion welding, can realize the seepage of pipeline zero by this way, greatly the sealing effectiveness of enhancing connection-peg, while it is easy to grafting to operate,
The manipulation strength during tubing project installation is substantially reduced, promotional value is high.
