The invention provides an oil tank isolation valve, an oil tank system and a vehicle. The oil tank isolation valve comprises a shell, a first plugging part and a moving part. The shell is provided with a first communication port and a second communication port, the first communication port is used for being connected with an oil tank, and the second communication port is used for being connected with an oil gas adsorption and desorption device. A partition plate is arranged in the shell and divides an inner cavity of the shell into a first cavity and a second cavity. The first cavity is communicated with the first communication port, and the second cavity is communicated with the second communication port. The partition plate is provided with a first through hole and a second through hole. The first plugging part is used for plugging the first through hole. The moving part is located in the first cavity and provided with a second plugging part. When the pressure of oil gas in the oil tank is larger than a first threshold value, the oil gas entering the first cavity pushes the first plugging part to move in the direction away from the partition plate, and the first through hole is opened. When the pressure in the oil tank is smaller than a second threshold value, external air entering the second cavity through the oil gas adsorption and desorption device pushes the second plugging part to move, and the second through hole is opened.

    本申请提供了一种油箱隔离阀、油箱系统及车辆。油箱隔离阀包括壳体、第一封堵部及移动部。壳体设有第一连通口与第二连通口,第一连通口用于与油箱连接,第二连通口用于与油气吸附脱附装置连。壳体内设有隔板,隔板将壳体的内腔分隔成第一腔室和第二腔室。第一腔室与第一连通口连通,第二腔室与第二连通口连通。隔板设有第一通孔和第二通孔。第一封堵部用于封堵第一通孔。移动部位于第一腔室,设有第二封堵部。油箱内油气的压力大于第一阈值时,进入第一腔室的油气推动第一封堵部向背离隔板的方向移动,使第一通孔打开。油箱内的压力小于第二阈值时,通过油气吸附脱附装置进入到第二腔室的外部空气推动第二封堵部移动,第二通孔打开。
