The invention relates to the field of marine ventilation equipment, and discloses a marine air pipe head long in service life, which comprises a pipe head body, a middle partition plate is fixedly connected to the top of the pipe head body, the middle partition plate is arranged in the middle of an inner cavity of the pipe head body, and middle through holes are formed in the two sides of the middle partition plate. The middle of the bottom end of the pipe head body is fixedly sleeved with a lower guide pipe, and the top of the lower guide pipe is connected with the bottom of the middle partition plate in a sealed mode. Through the linkage structure design of the floating block in the lower guide pipe and the piston plate in the upper guide pipe, the floating block is driven by water flow to move upwards to enable the piston plate to compress gas in the upper guide pipe, so that the sealing plate is driven to horizontally move to seal the vent hole, and frequent bounce and impact loss of the floating cylinder caused by shaking of sea waves in the driving process of the ship is avoided; and during long-term use, the follow-up sealing performance of the buoy is reduced due to impact loss when the buoy is opened and closed, so that the sealing effect is influenced.

    本发明涉及船用通气设备领域,且公开了一种使用寿命高的船用空气管头,包括管头本体,管头本体的顶部固定连接有中间隔板,所述管头本体内腔的中部设有中间隔板,所述中间隔板的两侧均开设有中间通孔,所述管头本体底端的中部固定套装有下位导管,所述下位导管的顶部与中间隔板的底部密封连接。通过下位导管内浮块与上位导管内活塞板的联动结构设计,利用水流带动浮块上移使得活塞板压缩上位导管内的气体,从而带动密封板水平移动来密封通气孔,避免了船在行驶过程中,因海浪而晃动,导致浮筒频繁的跳动撞击损耗,以及长期使用时,浮筒在打开关闭时的撞击损耗,导致浮筒的后续密封性能下降,影响密封效果的问题。
