The invention relates to the technical field of ship ventilation, and particularly discloses an air adjusting door and a gas transport ship. The air adjusting door comprises a ventilation pipeline and a rotating shaft. The rotating shaft is movably installed on the ventilation pipeline and partially extends into the ventilation pipeline, the part, located in the ventilation pipeline, of the rotating shaft is fixedly connected with an air adjusting assembly, the air adjusting assembly comprises an air adjusting plate and an elastic sealing ring connected to the edge of the air adjusting plate in a sleeving mode, and the rotating shaft can rotate around the axis of the rotating shaft so that the air adjusting door can be switched between the opening state and the closing state. When the air adjusting door is in a closed state, the outer surface of the elastic sealing ring is matched and attached to the inner wall of the ventilation pipeline so that the ventilation pipeline can be closed, and when the air adjusting door is in an open state, part of the elastic sealing ring and the inner wall of the ventilation pipeline are arranged at intervals so that the ventilation pipeline can be opened. According to the air regulating door, the air tightness of the air regulating door is improved by arranging the elastic sealing ring, so that toxic gas cannot enter a cabin through a ventilation pipeline, and the life safety of a user is guaranteed.
本发明涉及船舶通风技术领域,具体公开了调风门及气体运输船。该调风门包括通风管道和转轴;转轴活动安装于通风管道,转轴部分伸入通风管道,转轴位于通风管道内的部分固接有调风组件,调风组件包括调风板和套接于调风板边缘的弹性密封环,转轴能够绕转轴的轴线旋转,使调风门在打开状态与关闭状态之间切换,当调风门处于关闭状态时,弹性密封环的外表面与通风管道的内壁匹配贴合,使通风管道封闭,当调风门处于打开状态时,部分弹性密封环与通风管道的内壁间隔设置,使通风管道打开。该调风门通过设置弹性密封环的方式,得以改善调风门的气密性,从而使得有毒气体无法通过通风管道进入到舱室内部,进而保证了使用人员的生命安全。
