Manpower and materials；Flange and caging bolt are provided with, by the side of the flange that is fixed on interface and caging bolt and birdsmouth
Edge is fixed together, and when hydraulic pressure is larger, pipeline will not be washed open, in buried supply line, can prevent pipeline leak,
Only pier is eliminated, is constructed convenient；Interference fit between T-shaped O-ring seal and mounting groove is adopted simultaneously, and to ebonite part
Done and further limited in gap between mounting groove, between birdsmouth and interface so that meet two steel pipes of condition by
It is very good according to sealing after technology socket joint of the present utility model so that T-shaped O-ring seal can be compressed simultaneously in the presence of hydraulic pressure
Fill up gap, it is ensured that current will not spill, solve the technology that the excessive interface of cushion rubber can not be inserted, the too small sealing of cushion rubber is poor
Problem；Restriction protrusion is used for the sealing for ensureing cushion rubber, and the spacing draw-in groove of nuts is used to further fasten caging bolt, structure letter
, to be once stamped and formed out, moulding process is simple, low cost for list, restriction protrusion and the two structures of the spacing draw-in groove of nuts.This reality
New easy construction is used, when applying in Water and Waste Water Engineering, quality and economic effect are all fine, and the flexibility for realizing steel pipe connects
Mouth connection.
