Abstract
This paper presents the leakage safety of two O-rings, which are located at the rectangular groove between a valve body and a valve stem. The leakage safety analysis of 0-ring seals has been computed as functions of a compression set and a liquefied petroleum gas pressure of a LPG cylinder using a FEM program, MARC. The FEM computed results indicate that the loads from the filling pressure of
본 논문에서는 밸브몸체와 밸브스템 사이의 사각그루브에 설치한 두 개의 O-링에 대한 누설 안전성을 해석한 결과를 제시하고 있다. O-링시일의 누설 안전성에 대한 해석은 압축률과 LPG 가스압력의 변동에 따라 발생되는 누설 안전성을 유한요소해석 프로그램 MARC로 계산하였다. FEM 해석결과에 따르면, LP가스 충전압력
