The specific meaning of the above terms in the present invention can be understood in specific cases to those skilled in the art.
In the description herein, references to the description of the terms "an example," "one example," and "one implementation," etc., mean that a particular feature, structure, material, or characteristic described in connection with the example or implementation is included in at least one example or implementation of the invention. In this specification, the schematic representations of the terms used above do not necessarily refer to the same embodiment or implementation. Furthermore, the particular features, structures, materials, or characteristics described may be combined in any suitable manner in any one or more embodiments or implementations.
In the related art, when two pipelines are connected, the two pipelines are mainly connected through two oppositely arranged flange components, a plurality of bolt holes which are annularly and circumferentially arranged are formed in the end faces of the flange components, and the two flange components penetrate through the corresponding bolt holes through fixing bolts and are fixedly locked through fixing nuts; in the existing practical use process, the assembly mode that the inner aperture sizes of flanges on two sides are different is often met, and a boss plane is designed to serve as a sealing surface of a common flange. Under the working condition, because the flanges at the two sides are provided with the bosses, the sealing gasket is unevenly stressed due to uneven stress of the flange plate in the fastening process of the flange bolts, and the sealing gasket is easily extruded out of the sealing areas of the flanges at the two sides.
The existing flange sealing gasket mounting mode is mainly divided into two types:
the first scheme is as follows: the outer diameter of the sealing gasket is made small, and positioning is not carried out. The problem that does not fix a position the existence is exactly in the installation, and sealed the pad in the flange sealing face, inconvenient adjustment, simultaneously because the effect of gravity in the installation, sealed the pad is eccentric downwards, takes place the installation dislocation easily, very easily appears sealed the pad and is extruded and the phenomenon of leaking water after sealed the pad receives the extrusion atress inequality.
Scheme II: the gasket is made large and positioned by external bolts. The area of the sealing gasket is enlarged by using the external bolt for positioning, the sealing ring at the installation contact surface is removed, other parts do not participate in sealing, the waste of a large amount of materials and the increase of cost are caused, and meanwhile, the phenomena of extrusion and water leakage of the sealing gasket are easy to occur under the condition of uneven stress. The scheme is that the sealing gasket except for sealing and positioning is cut off, so that the area of the sealing gasket is reduced, but the phenomenon that the sealing gasket is extruded and leaks water still exists after the sealing gasket is extruded and stressed unevenly.
The two common schemes can not meet the assembly modes with different inner aperture sizes of the flanges at two sides, and the sealing gasket is easy to extrude and bear uneven force, so that the water leakage phenomenon is caused.
