Furnace hub flexible coupling type cast iron pipe joining mechanism

摘要

In this study, a through hole is formed in the center. In the through hole, a circular shrinkage hole (32) is formed at the root of the central part. The rubber cylinder (30) composed of an external surface is separated from two layers of air holes (50), and the two layers of air holes (50) are combined with each other, and a rubber cylinder port (50) is formed with the two surfaces The utility model is composed of a couple pair of rings (40) which are composed of the common parts receiving the gas circulation (30), and provides a Nuo vanilla mixed type cast iron pipe joint mechanism for the joint of cast iron pipes (10, 20),The joint mechanism of cast iron pipe in this study is simple in structure and easy to install, which greatly improves the sealing and structural stability of the joint of cast iron pipe.
