본 발명은 원통형 고압용기 고정용 링 브라켓에 관한 것으로서, 더욱 상세하게는 원통형 고압용기를 고정하는 링브라켓의 볼트체결부에서 체결단에 가까운 쪽 부분에 집중하중이 발생하는 것을 방지하게 하는 원통형 고압용기 고정용 링 브라켓에 관한 것이다.The present invention relates to a ring bracket for fixing a cylindrical high pressure vessel, and more particularly, a cylindrical high pressure vessel for preventing concentrated load from occurring at a portion close to a fastening end at a bolted portion of a ring bracket for fixing a cylindrical high pressure vessel. It relates to a fixing ring bracket.

고압용기는 일반적으로 용기에는 용접을 하지 못하므로 용접이 아닌 고정 브라켓으로 고정하여야 한다. 이때 고안가스안전관리법(압축천연가스 자동차 연료장치의 구조등에 관한 기준 8-2-2항)에 의하면 용기를 고정장치에 설치한 후 완전히 충전된 용기무게의 8배의 힘을 가할 경우 고정위치의 변형이 없어야 한다고 기준을 정하고 있다.High pressure vessels are generally not welded to the vessel, so they should be fixed with fixed brackets, not welds. According to the Designed Gas Safety Management Act (Standards 8-2-2 of the Structure of Compressed Natural Gas Vehicle Fuel System, etc.), if the vessel is applied to the fixed device and applied eight times the weight of the fully charged container, There is no criterion that there should be no deformation.

이는 고압용기가 고정부에서 분리되어 나올경우 고속으로 달리는 자동차에서 가스폭탄을 던지는 것과 같은 결과를 초래하게 된다.This results in the same as throwing a gas bomb in a car running at high speed when the high pressure container is separated from the fixed part.

우리나라 주요 수출국인 미국법규에는 상하, 전후, 좌우의 방향으로 용기 무게의 8배의 힘을 가할 경우 변위가 1/2" 이하일 것으로 정하고 있다.According to US regulations, the main exporting country of Korea, the displacement is less than 1/2 "when 8 times the weight of the container is applied in the up, down, front and rear directions.

자동차에 사용하는 원통형 고압용기를 고정하는 수단으로 도 1과 도 2에 도 시되어 있듯이 링브라켓(2)이 사용된다.A ring bracket 2 is used as shown in FIGS. 1 and 2 as a means for fixing a cylindrical high pressure vessel for use in an automobile.
