Detailed Description
Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are exemplary and intended to be used for explaining the present invention, and should not be construed as limiting the present invention.
As shown in fig. 1 and 2, the utility model provides a can cushion return bend of impact, connect 2 and the second joint 3 at 1 both ends of return bend body including return bend body 1 and respectively, 1 overcoat of return bend body is equipped with buffering return bend 4, and return bend body 1 is close to first joint 2, all is provided with along the multiunit opening 5 of the axis direction range of return bend body on the position that return bend body 1 is close to second joint 3, and the inner chamber of return bend body 1 is linked together through opening 5 and the inner chamber of buffering return bend 4.
Particularly, the bent pipe as a connecting piece can be widely applied to the technical field of engineering, and particularly can be applied to a pipeline system.
The return bend can include return bend body 1 and connect first joint 2 and the second of 1 both ends of return bend body and connect 3, and wherein the connected mode between first joint 2 and second joint 3 and return bend body 1 has multiple mode, for example, be integrated into one piece between the three, also can be for the components of a whole that can function independently structure, when return bend body 1, first joint 2, second joint 3 are for the components of a whole that can function independently structure, can also carry out fixed connection through threaded connection's mode through the welded mode.
