Title
(EN) GASKET CONTROL METHOD, SYSTEM, AND PROGRAM
(FR) PROCÉDÉ, SYSTÈME ET PROGRAMME DE RÉGLAGE DE JOINT D'ÉTANCHÉITÉ
(JA) ガスケットの管理方法、システムおよびプログラム
Abstract
(EN) Tightening of a gasket (8) held between flanges (6-1, 6-2) is controlled on the basis of a step in which a load due to tightening is applied, a step in which a change in the shape of the gasket generated by the load is observed, and the change in shape. The change in shape includes a change in the gasket in at least the direction of the interval between the flanges, or a change in a direction orthogonal to the interval direction, or both of said changes. Thus, if a change in the shape of the gasket receiving the load is observed, tightening of the gasket can be controlled.
(FR) Le serrage d'un joint d'étanchéité (8) maintenu entre des flasques (6-1, 6-2) est réglé en se basant sur une étape dans laquelle une charge due au serrage est appliquée, une étape dans laquelle un changement de la forme du joint d'étanchéité généré par la charge est observé, et le changement de forme. Le changement de forme comprend un changement dans le joint d'étanchéité dans au moins la direction de l'intervalle entre les flasques, ou un changement dans une direction orthogonale à la direction d'intervalle, ou les deux changements. Ainsi, si un changement de la forme du joint d'étanchéité recevant la charge est observé, le serrage du joint d'étanchéité peut être réglé.
(JA) フランジ(6-1、6-2)間に拘束されたガスケット(8)に、締付けによる荷重を付与する工程と、前記荷重により前記ガスケットに生じる形状変化を観測する工程と、前記形状変化に基づき前記ガスケットの締付けを管理する。前記形状変化は前記ガスケットの少なくとも前記フランジ間の間隔方向の変化、または間隔方向と交差方向の変化の何れかまたは双方を含む。これにより荷重を受けるガスケットの形状変化を観測すればガスケットの締付けを管理することができる。
