The pressure relief type oil tank comprises an oil tank body, a pressure relief device is arranged on one side of the oil tank body, an inlet of the pressure relief device is communicated with an inner cavity of the oil tank body through the top of the oil tank body, and a compression pump capable of sending gas in the inner cavity of the oil tank body to the pressure relief device is arranged between the pressure relief device and the oil tank body; an upper perforated plate and a lower perforated plate are arranged in an inner cavity of the pressure relief device, liquid absorption cotton is arranged between the upper perforated plate and the lower perforated plate, and the upper perforated plate and the lower perforated plate are suitable for relatively moving and extruding the liquid absorption cotton; an opening and closing valve is arranged between the outlet of the pressure relief device and the oil tank; the top wall of the oil tank is provided with a balancing device capable of communicating the inner cavity with the outside to regulate and control pressure balance inside and outside the oil tank; mixed gas containing air and gasoline steam in the oil tank is fed into the pressure relief device through the compression pump to be pressurized, the gasoline steam is liquefied by means of the boiling point, higher than that of the air, of the gasoline steam, gas-liquid separation is achieved between the gasoline steam and the air, the gasoline steam in the oil tank is liquefied and flows back into the oil tank, and therefore the pressure resistance problem of the oil tank is solved.

    本发明公开了一种泄压型油箱,包括油箱,油箱的一侧设有泄压器,泄压器的入口通过油箱的顶部与油箱内腔连通,泄压器与油箱之间设有能将油箱内腔中的气体送往泄压器的压气泵;泄压器内腔中设有上穿孔板和下穿孔板,上穿孔板与下穿孔板之间设有吸液棉,上、下穿孔板适于相对移动并挤压吸液棉;泄压器的出口与油箱连通并在两者之间设有可开闭的阀;油箱的顶壁上设有能连通内腔与外界以调控油箱内外压力平衡的平衡装置;压气泵将油箱内的包含空气与汽油蒸气的混合气体送入泄压器内加压,利用汽油蒸气比空气更高的沸点,使汽油蒸气液化并与空气实现气液分离,实现将油箱内的汽油蒸气液化并回流至油箱中,从而解决油箱的耐压问题。
