Abstract

In this paper, the valves for a LPG gas cylinder have been investigated on the body height and weight by comparing design data between typical automatic shut-off vertical and newly developed horizontal valves. The height of an automatic shut-off horizontal valve is radically reduced by 41~42% compared with that of a typical automatic shut-off vertical valve. And, the body weight of a horizontal valve is also reduced by 29~40% compared with that of a vertical shut-off valve. This result is just achieved by a structural design modification from typical vertical valve to horizontal arrangement of various valve components.

본 연구에서는 기존의 차단기능형 수직식 용기밸브와 새로이 개발된 수평식 용기밸브의 몸체전고와 중량에 대한 설계 데이터를 고찰하였다. 차단기능형 수평식 용기밸브의 전고는 기존의 차단기능형 수직식 용기밸브에 비해 41~42%나 획기적으로 줄어들었다. 또한, 수평식 밸브의 몸체 무게는 기존의 차단기능형 수직식 밸브에 비해 29~40%나 줄어든 결과를 얻었다. 이러한 결과는 단지 기존의 수직식 밸브에서 밸브의 여러 가지 구성요소를 수평식으로 배열을 바꾼 구조변경 설계를 통해 확보한 것이다.
