Abstract
The invention relates to a sealing structure of pipeline flanges. The structure comprises a first flange and a second flange, the outer edge of the second flange axially extends to form a round groove in a protruding mode, the first flange is inserted into the round groove in a matched mode, the inner edge of the first flange axially extends to form an annular boss in a protruding mode, the annular boss is provided with a slope, the inner edge of the second flange is axially concave to form an annular groove corresponding to the annular boss in shape, two layers of sealing rings are fixedly clamped between the first flange and the second flange in an attached mode, each sealing ring is provided with a bent portion corresponding to the annular boss or the annular groove in shape, and the first flange and the second flange are fixedly connected through a bolt. The sealing structure of the pipeline flanges enhances sealing performance between the flanges and avoids water seepage and water dripping phenomena.
Description
Technical field
The present invention relates to a kind of sealing configuration of piping flange.
Background technique
The sealing of piping flange of the prior art, normally arranges one deck O RunddichtringO between two Flange joint planes, and is bolted to connection two flanges.But find in actual applications, because the planeness of two Flange joint planes exists error, there is matching gap when assembling, causing the O RunddichtringO assembled between latter two flange to there is certain small spaces, thus cause the phenomenon seeping water, drip to occur.
Summary of the invention
The object of the invention is to the problem overcoming above-mentioned prior art, provide a kind of sealing configuration of piping flange, it can strengthen the sealability between flange, avoids the generation of infiltration and dripping phenomenon.
The object of the invention is to be achieved through the following technical solutions:
A kind of sealing configuration of piping flange, comprise the first flange and the second flange, the outer rim of described second flange axially protrudes out formation circular groove, described first flange cooperation is plugged in described circular groove, the inner edge of described first flange axially protrudes out and forms the sloping annular boss of tool, the inner edge axial depression of described second flange forms the annular groove adapted with described annular boss shape, fit between described first flange and described second flange and grip two-layer seal ring, described seal ring has the bending part adapted with described annular boss or annular groove shaped, described first flange is fixedly connected with described second flange bolt.
Further, the angle of inclination on described slope is 45 degree.
Further, the thickness of described seal ring is 5mm.
The sealing configuration of a kind of piping flange of the present invention, comprise the first flange and the second flange, the outer rim of the second flange axially protrudes out formation circular groove, first flange cooperation is plugged in circular groove, the inner edge of the first flange axially protrudes out and forms the sloping annular boss of tool, the inner edge axial depression of the second flange forms the annular groove adapted with annular boss shape, fit between first flange and the second flange and grip two-layer seal ring, seal ring has the bending part adapted with annular boss or annular groove shaped, first flange is fixedly connected with the second flange bolt.The sealing configuration of the piping flange of this structure, enhances the sealability between flange, avoids the generation of infiltration and dripping phenomenon.
Accompanying drawing explanation
Fig. 1 is the structural representation of the sealing configuration of a kind of piping flange of the present invention.
Embodiment
According to drawings and embodiments the present invention is described in further detail below.
As shown in Figure 1, the sealing configuration of a kind of piping flange described in the embodiment of the present invention, comprise the first flange 1 and the second flange 2, the outer rim of the second flange 2 axially protrudes out and forms circular groove 21, first flange 1 cooperation is plugged in circular groove 21, the inner edge of the first flange 1 axially protrudes out the annular boss 11 being formed and have slope 1a, the inner edge axial depression of the second flange 2 forms the annular groove 22 adapted with annular boss 11 shape, fit between first flange 1 and the second flange 2 and grip two-layer seal ring 3, seal ring 3 has the bending part 31 adapted with annular boss 11 or annular groove 22 shape, first flange 1 is fixedly connected with the second flange 2 bolt.
The angle of inclination of slope 1a is 45 degree.The thickness of seal ring 3 is 5mm.In the present embodiment, by the setting of two-layer seal ring, effectively prevent the formation of slight gap during assembling, further enhancing sealability by the boss of slope shape and the setting of circular groove simultaneously.
The foregoing is only explanation embodiments of the present invention; be not limited to the present invention, for a person skilled in the art, within the spirit and principles in the present invention all; any amendment of doing, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
