Abstract

본 발명은 주유소에 있어서의 지하탱크에 접속한 통기관(痛氣菅)에 설치되어 내압 상승시에 자동적으로 유로를 폐쇄하여 가스를 탱크로리(tank lorry)의 탱크 내로 회수하기 위한 통기밸브에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a vent valve for recovering gas into a tank of a tank lorry by being installed in a vent pipe connected to an underground tank at a gas station and automatically closing the flow path when the internal pressure rises.

본 발명에 따르면, 통기관의 도중에 설치된 하우징에 대해 밸브 케이싱을 카트리지식으로 출입 가능하도록 하고 있으므로, 밸브 요소의 보수점검이나 부품교환시에는 통기관을 분해하거나 할 필요없이 밸브 케이싱을 출입시키는 작업만으로 완료되면, 작업시간의 단축에 의해 주유소의 영업에 지장을 초래하지 않게 됨과 동시에, 작업중에 가스의 방출도 작게 억제되므로 안전한 환경이 유지된다.According to the present invention, since the valve casing is made to be accessible in the cartridge type to the housing installed in the middle of the vent pipe, when the maintenance of the valve element or the parts are replaced, the valve casing is completed without the need to disassemble the vent pipe. As a result, the operation time of the gas station is not impeded by the shortening of the working time, and the emission of gas is also suppressed during the operation, thereby maintaining a safe environment.
