The air suction prevention oil tank comprises an oil tank body and an air suction prevention device, the air suction prevention device is arranged at the bottom of the oil tank body, the air suction prevention device comprises floating valve suction heads, an oil conveying pipe and an oil outlet pipe, the floating valve suction heads are arranged at the four corners of the bottom of the oil tank body respectively, and the interior of each floating valve suction head is hollow to form an oil suction channel; when fuel oil at the position where the floating valve suction head is located provides enough buoyancy for the buoyancy head of the floating valve suction head, the oil suction channel is opened, when the buoyancy generated by the fuel oil at the position where the floating valve suction head is located on the buoyancy head is insufficient, the oil suction channel is closed, air suction is avoided, and the floating valve suction head is connected with the oil outlet pipe through the oil conveying pipe. By means of the design, when little fuel oil is left in the oil tank and the oil tank shakes, the floating valve suction head with the fuel oil liquid level lower than the height of the buoyancy head is closed, the floating valve suction head with the fuel oil liquid level higher than the height of the buoyancy head continues to suck oil, and therefore it is guaranteed that the fuel oil supplied outwards by the oil outlet pipe does not contain air.
本发明公开一种防空吸油箱,包括油箱和防空吸装置,所述防空吸装置设置在油箱的底部,所述防空吸装置包括漂浮阀吸头、输油管及出油管,所述漂浮阀吸头在所述油箱底部的四角分别设置,所述漂浮阀吸头的内部中空形成吸油通路,所述漂浮阀吸头在所处位置的燃油为漂浮阀吸头的浮力头提供足够浮力时,吸油通路打开,在漂浮阀吸头所处位置的燃油对浮力头产生的浮力不足时吸油通路关闭,避免吸入空气,所述输油管将所述漂浮阀吸头与出油管连接。通过这样的设计,当油箱内所剩燃油较少且发生摇晃时,所处位置的燃油液面低于浮力头高度的漂浮阀吸头关闭,而所处位置燃油液面高于浮力头高度的漂浮阀吸头继续吸油,从而保证出油管向外供出的燃油不包含空气。
