Title:
GASKET, CONTROL METHOD AND SYSTEM THEREFOR, AND PROGRAM
Document Type and Number:
WIPO Patent Application WO/2022/009865
Kind Code:
A1
Abstract:
This gasket is provided with outer cuts (4-1, 4-2, 4-3, 4-4) in a non-restrained portion (2-2) disposed adjacent to a restrained portion (2-1) that is restrained between flanges (16-1, 16-2). The outer cuts change shape due to a load exerted on the restrained portion. The shapes of the outer cuts that have undergone a change under the aforementioned load are measured, and clamping of the gasket is controlled on the basis of the measured shapes. Accordingly, it is possible to directly observe a change in the shape of a gasket that is subjected to a load between flanges and to use the observation result for the purpose of controlling the clamping of the gasket so as to improve the gasket and control technology therefor.
