Embedded socket press fit pipe fitting

Abstract

The utility model discloses an embedded socket press-fit pipe fitting, which belongs to the technical field of pipeline connecting devices, and comprises end parts and a main body part positioned between the end parts, the end parts are used as connecting parts with pipes, the end parts are of a double-layer structure, and are respectively a core sleeve layer positioned on the inner side and a shell layer positioned on the outer layer; the end part of the core sleeve layer is longer than the end part of the shell layer, at least one groove is formed in the core sleeve layer, and a transition piece is arranged in the groove; according to the utility model, at least one groove, preferably one groove, is formed in the core sleeve layer of the socket press-fit pipe fitting, and a rubber ring and the like are arranged in the groove to serve as transition pieces, so that on one hand, the effect of blocking a sealant can be achieved, and on the other hand, the sealing performance, the drawing resistance and the vibration resistance after the socket press-fit pipe fitting is connected with a pipe can be obviously improved, and the service life of the socket press-fit pipe fitting is prolonged. Therefore, the connection glue overflow possibility is greatly reduced, and the connection reliability is further improved.
