THREADLESS COUPLING FOR PIPES AND AIR-TIGHT INNER CYLINDER THEREFOR |
摘要 |
A threadless coupling for pipes has a cylindrical coupling body having longitudinally-extending slots or sections along the entire length thereof, a pair of grip sections forming grooves facing oppositely from each other on the outside of the edges of both ends of the opening section of the coupling body, and a grip case which is slidable fitted for coupling on the pair of grip sections. The grip case is tapped with a hammer of the like to slide onto the pair of grip sections, thereby compressing the coupling body around the conduits to be coupled by decreasing the gap between the pair of grip sections and accordingly reducing the diameter of the coupling body.
