Metal winding type gasket, inner ring, centering ring and metal winding type gasket component

Abstract

The invention discloses a metal winding type gasket, an inner ring, a centering ring and a metal winding type gasket component. The problem that the present metal winding type gasket component is completely discarded after being used is solved. According to the technical scheme, the metal winding type gasket component comprises the metal winding type gasket and the inner ring and / or the centering ring which is matched and sleeved with the metal winding type gasket, wherein a plurality of brackets are uniformly arranged on an inner supporting ring and / or an outer supporting ring of the metal winding type gasket, and a plurality of bracket clamping holes are correspondingly and uniformly arranged on the inner ring and / or the centering ring. The metal winding type gasket component has a simple structure, is flexible to mount and is excellent in reliability; after the metal winding type gasket component is used, the corresponding damaged component can be exchanged and the undamaged component is not exchanged; and the production and use costs are effectively lowered.

Description

technical field [0001] The invention relates to the field of gaskets, in particular to a metal wound gasket, an inner ring, a centering ring and a metal wound gasket assembly. Background technique [0002] Metal wound gaskets have been widely used in petrochemical and other fields, and the use effect is very good. Metal wound gaskets are made of "V" or "W" shaped metal strips and non-metallic strips overlapping each other and continuously wound, and the metal strips are fixed by spot welding at the beginning and end. [0003] There are four types of metal wound gasket components. In addition to the basic type, the commonly used types are the type with inner ring, the type with centering ring, the type with inner ring and the type with centering ring. The type with an inner ring refers to the inner ring embedded in the inner ring of the metal wound gasket; the type with a centering ring refers to a centering ring on the outer ring of the metal wound gasket; the type with an ...

AI Technical Summary

Problems solved by technology

The type with an inner ring refers to the inner ring embedded in the inner ring of the metal wound gasket; the type with a centering ring refers to a centering ring on the outer ring of the metal wound gasket; the type with an inner ring and a centering ring It means that the inner ring of the metal wound gasket is embedded with an inner ring, and the outer ring is also covered with a centering ring; in the above-mentioned structural forms, the socket of the metal wound gasket and the inner ring and / or outer ring is usually It is a clamping form that uses the ring-shaped clip formed during the production process of the metal wound gasket to match the ring-shaped clip groove opened on the inner ring and / or the centering ring. Once assembled, it cannot be disassembled. If it is disassembled forcibly It will make the card slot or card strip partially damaged and cannot be used again

The non-reusable feature of the metal wound gasket assembly brings the following problems: For the three types of metal wound gasket assemblies: the type with inner ring, the type with centering ring, and the type with inner ring and centering ring, once the metal winding If the belt fails, not only the metal wound gasket fails, but also the inner ring and / or centering ring used with it are also discarded

Due to the particularity of the process medium of petrochemical and other equipment, the material of the inner ring and (or) centering ring of the metal wound gasket assembly is relatively expensive, such as 0Cr18Ni9 (304), 00Cr19Ni10 (304L), 0Cr17Ni12Mo2 (316), 00Cr17Ni14Mo2 (316L ), 0Cr18Ni10Ti (321), 0Cr18Ni11Nb (347), etc. During the use of metal wound gasket components, the easily damaged part is generally the metal wound tape part, and the inner ring of the metal wound gasket and (or) the pair Middle rings are generally not easily damaged, so such a crude use of metal wound gaskets is a huge waste of resources
