The invention discloses an LNG fuel tank ventilation mast, belongs to the field of shipbuilding, relates to the technology of ventilation masts, and is used for solving the problem that a traditionalventilation mast cannot meet the ventilation requirement of an LNG tank cabin. Through an auxiliary exhaust mechanism, a ventilation cap can be exhausted through an auxiliary air inlet and outlet in the auxiliary exhaust mechanism when being damaged, and danger caused by uneven internal and external pressure intensity is avoided; meanwhile, a sliding device is further installed in a rolling lantern ring, the sliding device comprises a supporting base, a steel ball is arranged in the supporting base, a rolling spring is installed between the steel ball and the supporting base, and the vacant position in the supporting base is filled with lubricating oil; sliding devices are arranged on the two sides of an air inlet and outlet connecting pipe; an exhaust extension rod in the high altitude isslightly deformed and does not drive the rolling lantern ring to move, so that the reliability of the rolling lantern ring is guaranteed; and an emergency conveying device is arranged at the bottom end of a main rod, so that a emergency connector is prevented from being damaged.

    本发明公开了一种LNG燃料舱透气桅,本发明属于船舶制造领域,涉及透气桅技术,用于解决传统的透气桅无法满足LNG罐舱的通风要求的问题;通过辅助排气机构,使得透气帽遇到损坏时也可以通过辅助排气机构内的辅助进出气口排除,避免内外压强不均匀造成危险;同时由于滚动套环内还安装有滑动装置,滑动装置包括支撑座,支撑座内设有钢珠,钢珠与支撑座之间安装有滚动弹簧,且支撑座内空余处填充有润滑油;滑动装置设于进出气连接管的两侧;使得处于高空中的排气伸长杆细微变形不会带动滚动套环运动,进而保证滚动套环的可靠性;通过在主杆的底端设置应急输送装置,避免应急接口损坏。
