Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments.

In the description of the present invention, it is to be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", and the like, indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, are merely for convenience in describing the present invention and simplifying the description, and do not indicate or imply that the device or element being referred to must have a particular orientation, be constructed and operated in a particular orientation, and thus, should not be construed as limiting the present invention.

Example one

Referring to fig. 1-3, a socket joint pressfitting formula elbow of flanged, including return bend 1 and the pipeline 3 of being connected with return bend 1, return bend 1 keeps away from the one end welding of pipeline 3 and has ring flange 2, the mounting groove has been seted up to the inner wall of return bend 1, movable post 5 is installed to the mounting groove internal rotation, the outer wall of movable post 5 is fixed with clamping jaw 6, the quantity of movable post 5 is a plurality of, guarantee sufficient quantity's clamping jaw 6 and pipeline 3 contact, guarantee the steadiness of connecting, be fixed with on the inner wall of pipeline with 3 outer wall interference fit's O type sealing washer 4, to treat that the pipeline 3 of connecting inserts to return bend 1 in, O type sealing washer 4 is inserted to the tip of pipeline 3, make O type sealing washer 4 and pipeline 3 abundant contact support tightly through interference fit, guarantee the leakproofness.

When pipeline 3 inserts to return bend 1 in, drive movable post 5 reverse rotation, drive clamping jaw 6 and rotate toward the outside, when pipeline 3 has the trend of outside motion, drive movable post 5 through the friction and rotate toward the inboard, make clamping jaw 6 support tightly with the outer wall of pipeline 3, prevent that pipeline 3 from removing toward the outside, prevent that pipeline 3 from breaking away from.
