A contractible joint device for metal conduit |
摘要 |
A contractible joint device for metal conduit (10), includes an inlet short pipe (1), a short outlet pipe (2) and a casing coupling (3). The opposite inner ends of the said two short pipes (1, 2) are placed in casing coupling (3) with a come-and-go clearance (6) between said inner ends. A corrugation pipe (7) is placed and can be axially moved back and forth by a force in said come-and-go clearance (6). The two ends of the said corrugation pipe (7) are connected respectively with the inner ends of the two short pipes to form a seal, and at least one of the ends of casing coupling (3) is free with relative to two short pipes (1, 2). <IMAGE> |
