Abstract

The invention relates to a metal-coated sealing ring which comprises a metal coating layer, stuffing and at least one layer of elastic framework, wherein the elastic framework is supported in a cavity formed by the metal coating layer and drives the stuffing filled in the cavity to rebound together after stress acting on the metal-coated sealing ring is removed. In order to overcome the defect that the conventional metal-coated sealing ring only can be used once since the resilience is very small after deformation, the invention provides a metal-coated sealing ring which has large resilience and can be reused.

Description

technical field [0001] The invention relates to a sealing element. Specifically, it is a metal clad sealing ring. Background technique [0002] The sealing ring is one of the most common sealing elements in the field of mechanical manufacturing and mechanical maintenance, and the sealing ring includes wound sealing rings and wrapping sealing rings. Wound seal rings have a high rebound rate, but they are easy to open and loose, so special care must be taken during installation, and the installation is difficult. The wrap-around seal ring is easy to install, and the metal wrap-around seal ring is a commonly used wrap-type seal ring. The cross-sectional structure of the existing metal clad sealing ring is as follows: figure 1 As shown, it includes an outer metal cladding layer 1 and a filler 2 filled in the cladding layer 1, wherein the filler 2 is generally made of a flexible material. When in use, the sealing ring is compressed and deformed to play a sealing role. Due to ...
