Abstract
The utility model relates to a pipeline connector structure, in particular to a connector structure of a ductile cast iron pipe. A baffle ring mounting groove and a sealing ring mounting groove are arranged on the inner cylindrical surface of a bell of the ductile cast iron pipe. A sealing ring is embedded in the sealing ring mounting groove. An anchoring ring is arranged on the outer cylindrical surface of a spigot, is arranged between the baffle ring mounting groove and the sealing ring mounting groove, and approaches to the baffle ring mounting groove. A baffle ring mounting hole is arranged on the end surface of the bell, and is communicated with the baffle ring mounting groove. A baffle ring is embedded in the baffle ring mounting groove from the baffle ring mounting ring. The right end surface of the baffle ring approaches to the anchoring ring, and the left end surface approaches to the left ring surface of the baffle ring mounting groove. The utility model has the advantages of simple structure and firm connection, and is suitable for the pipelines with various calibers and various pressures.
