Abstract
The utility model relates to a mounting flange for a check valve, which comprises a flange main body (1), wherein an annular slot (2) is arranged on the front face of the flange main body, a submerged annular step face (3) is arranged in the center of the flange main body (1), a mounting slot (4) is arranged on the outer edge of the annular step face (3), and both ends of the mounting slot (4) are provided with mounting holes (5). Because the annular slot, the annular step face, the mounting slot and the mounting holes are designed, the mounting flange for a check valve has the advantages of good sealing performance, high connection strength and high safety performance.
Description
Technical field
The utility model relates to a kind of flange, relates in particular to a kind of safety check and uses mounting flange, belongs to the pipe fitting technical field.
Background technique
Flange is flange plate or bead again.Flange is to make pipe and the interconnective part of pipe, is connected in pipe end.Perforation on the flange, bolt are close to two flanges.Seal with liner between flange.Flange branch be threaded (wire connection) flange and welded flange.
Traditional flange that is used for safety check makes sealability bad owing to only connect through mounting hole, and join strength is lower, and Safety performance is relatively poor.
Summary of the invention
The purpose of the utility model is to overcome above-mentioned deficiency, and a kind of good seal performance is provided, and join strength is higher, and the higher safety check of Safety performance is used mounting flange.
The purpose of the utility model is achieved in that
A kind of safety check is used mounting flange; It comprises flange body, and the front of said flange body is provided with annular groove, and the middle part of said flange body is provided with the annular table terrace of sinking; The outer rim of said annular table terrace is provided with a mounting groove, and the two ends of said mounting groove are provided with mounting hole.
Compared with prior art, the beneficial effect of the utility model is:
The utility model is because the design of annular groove, annular table terrace, mounting groove and mounting hole makes this safety check have good seal performance with mounting flange, and join strength is higher, the Safety performance advantage of higher.
