According to the fuel tank valve and the vehicle, the valve body is installed on the fuel tank connector, the pressure maintaining containing cavity is formed between the valve body and the valve body installation cavity of the fuel tank connector, and the pressure maintaining body is further arranged in the pressure maintaining containing cavity in a sliding mode; the output channel of the valve body is closed in a pressure maintaining mode through the gravity of the pressure maintaining body. According to the fuel tank connector, the pressure maintaining body is arranged, and the area of the valve body mounting cavity of the fuel tank connector in the horizontal direction is fully utilized, so that on the premise that the required weight of the pressure maintaining body is maintained, compared with a scheme of a cylindrical pressure maintaining shell or a steel ball, the occupied space in the height direction can be greatly reduced; the distance between the valve body and the top face of the inner cavity of the valve body installation cavity is greatly reduced, further upward arrangement of the valve is facilitated, the upper limit of the closing height of the valve is improved, and the risk of dynamic leakage of the valve is reduced.

    本发明提供了一种燃油箱阀及车辆,通过将阀本体安装至燃油箱连接器,并在阀本体与与燃油箱连接器的阀体安装腔之间形成保压容置腔,并进一步在该保压容置腔内滑动设置保压本体,由保压本体自身重力对阀本体的输出通道进行保压关闭。设置保压本体,充分利用燃油箱连接器的阀体安装腔在水平方向上的面积,使得保压本体在维持所需重量的前提下,相对于圆柱形保压壳或钢珠的方案,可大大减小在高度方向上的所占用的空间,即大大减小了阀本体与阀体安装腔的内腔顶面之间的距离,有利于阀门进一步向上布置,提高了阀门关闭高度的上限,降低了阀门动态泄漏的风险。
