Technical Field
[0001] The utility model relates to the technical field of steel ball valves, in particular to a directly buried steel ball valve with a PE pipe. Background Art
[0002] At present, PE pipes have been widely used in the urban gas transmission and distribution pipe networks in China. Most of the valves originally set on PE pipes are PE valves, and the connection with the pipes generally adopts hot melt butt joint or capacitive connection. Since the PE material is greatly affected by factors such as temperature, the reliability and safety of PE valves are relatively poor. Therefore, it is also desirable to use steel or iron valves with good reliability and safety on PE pipes.
[0003] Traditional connection structures or connection methods cannot be used for the connection between steel or iron valves and PE pipes. Therefore, the connection between PE pipes and steel or iron gas valves in gas transmission and distribution is an important technical problem that needs to be solved currently.
