Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

It should be noted that: like reference numbers and letters refer to like items in the following figures, and thus, once an item is defined in one figure, it need not be further defined and explained in subsequent figures.

In the description of the present invention, it should be noted that, if the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer" and the like indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, or the orientation or positional relationship which is usually placed when the product of this application is used, the description is only for convenience of description and simplification, but the indication or suggestion that the device or element to be referred must have a specific orientation, be constructed in a specific orientation and be operated is not to be construed as limiting the present invention.

In the description of the present invention, it should be further noted that unless otherwise explicitly stated or limited, the terms "disposed," "mounted," "connected," and "connected" should be interpreted broadly, and may be, for example, fixedly connected, detachably connected, or integrally connected; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meaning of the above terms in the present invention can be understood in specific cases to those skilled in the art.

Example 1

This embodiment provides a double containment flange connection structure, includes two ring flanges through bolt 7 is fixed, two the medial surface of ring flange between be provided with bellied socket joint portion, the regional of socket joint portion periphery is built on stilts, can effectively alleviate the weight of flange, socket joint portion includes the bulge loop of two mutual socket joint connections, is provided with radial seal ring 6 between two bulge loops, and the bulge loop after the socket joint corresponds the ring flange of the corresponding side of butt respectively to realize spacing each other of two ring flanges, be convenient for connect, and have at least one bulge loop and correspond to be provided with axial seal ring 5 between the ring flange of butt.

Specifically, referring to fig. 1: defining two flange plates as a first flange plate 1 and a second flange plate 2, respectively, and the convex ring integrally formed on the inner side end surface of the first flange plate 1 is a first convex ring 3, and the convex ring integrally formed on the inner side end surface of the second flange plate 2 is a second convex ring 4, it should be noted that, in the actual use process, the first convex ring 3 may be placed into the second convex ring 4, or the second convex ring 4 may be placed into the first convex ring 3, for convenience of description, in this embodiment, the inner diameter of the first convex ring 3 is set to be the same as the outer diameter of the second convex ring 4, so as to achieve that the second convex ring 4 is placed into the first convex ring 3, a radial seal ring 6 is disposed between the outer end surface of the first convex ring 3 and the inner side end surface of the second flange plate 2, conceivably, the radial seal ring 6 may be disposed on the outer end surface of the first convex ring 3 (as shown in fig. 1), or on the inner side end surface of the second flange plate 2 (as shown in fig. 5), for sealing the gap between the first flange 3 and the second flange 2.
