TJG-Z型“锥套管式接头”铸铁管接口技术已获得1985年国家技术专利.它将铸铁管的形状做了重大改革,取消了铸铁管的承插口部分,采用锥套管将两根直形铸铁管连接(见附图),两段直形铸铁管中间加隔环和连接套将其位置大概固定,连接套和铸铁管之间充以橡胶圈和隔离圈,橡胶圈又被套在管子外面的环状压盘压住,压盘上穿有特制的螺栓,螺栓将橡胶圈挤压在压盘和连接套之间的锥形空间,橡胶圈被压紧,起到铸铁管的连接和密封作用.
TJG-Z-type “Cone tube fittings ” cast iron pipe interface technology has obtained the national technical patent in 1985. It made a great reform in the shape of the cast iron pipe, canceled the socket part of the cast iron pipe, Two straight cast iron pipe connection (see photo), two straight cast iron pipe with a spacer ring and the connecting sleeve about its position is fixed, between the connecting sleeve and cast iron pipe filled with rubber ring and isolation ring, rubber ring and Was set in the pipe outside the annular pressure plate to suppress the pressure plate to wear a special bolt, the rubber ring will be squeezed in the pressure plate and connecting sleeve conical space between the rubber ring is pressed to play a cast iron pipe The connection and sealing effect.
