The bellmouth joint at pipe two ends and socket connector, the bellmouth of the socket connector and the 3rd steel pipe that are respectively intended to the second steel pipe of connection connects
Head, the outer wall shape of the socket connector matches with the inner wall shape of the bellmouth joint, it is characterised in that the bellmouth connects
By the first sealing ring interference fit between head and the socket connector, the tube wall of the steel pipe is provided with metal protective cap, institute
Metal protective cap is stated by wired earth, and the metal protective cap and the outer wall of steel pipe are equipotential link, the steel pipe
Inwall is provided with inner liner, and the inner liner is brought into close contact with the steel pipe inner wall, and the inner liner of the socket connector holds with described
The inner liner joint of mouth joint is provided with the second sealing ring, and the inwall of the socket connector has 1- with the outer wall of the bellmouth joint
The gap of 2mm.
Hanger is symmetrically welded with the outer wall of the bellmouth joint and the socket connector.
Two symmetrical hangers are respectively equipped with the outer wall of the bellmouth joint and the socket connector.
Distance of the hanger apart from bellmouth fitting end or socket connector end is 1.2m.
The bellmouth joint dilates mode and is formed by machinery.
The inner liner is polyurethane inner liner or epoxy resin inner liner.
The beneficial effects of the utility model are：Hanger is used to realize the carrying of two socket joint steel pipes；Arrange in outer wall of steel pipe
Metal protective cap, solves when feedwater spigot-and-socket welded still pipe is laid in underground and holds corrosion-prone problem, also solves underground
The ground wire problem of piping lane protection against electric shock, extends the service life of steel pipe；Inner liner can prevent abrasion of the current to steel pipe inner wall
And corrode, inner liner is brought into close contact with steel pipe inner wall so that steel pipe plays pressure-bearing effect, and then inner liner is hardly damaged,
Ensure that endothecium structure and layer structure are not destroyed simultaneously；First sealing ring is installed between bellmouth joint and socket connector, it is complete
Into being tightly connected between two steel pipes；The inwall of socket connector has the gap of 1-2mm with the outer wall of bellmouth joint so that full
Two steel pipes of sufficient condition are very good according to sealing after technology socket joint of the present utility model, solve the excessive socket connector of cushion rubber
Can not insert, the technical problem of cushion rubber too small sealing difference, and be not in use accident, steel can be effectively improved
Tubular construction security reliability；The setting of the second sealing ring further ensures the sealing of pipeline.
