The invention relates to an oil tank pressure stabilizing system and a vehicle. The oil tank pressure stabilizing system comprises an isolating valve, a pressure stabilizing valve and a pressure stabilizing valve, when the one-way valve is opened, the one-way valve is used for communicating the interior of the oil tank with the outside and ensuring that fluid flowing through the one-way valve flows unidirectionally; the oil tank pressure sensor is arranged in the oil tank and is used for detecting the internal pressure of the oil tank; the controller is used for controlling opening and closing of the isolating valve and the one-way valve to adjust the internal pressure of the oil tank after receiving the refueling application signal, and the controller is further used for receiving a signal of the oil tank pressure sensor and outputting a safety signal to open the oil tank conveniently after the pressure difference between the inside of the oil tank and the outside is within a safety range. According to the oil tank pressure stabilizing system, by arranging the one-way valve communicating the interior of the oil tank with the outside, outside gas enters the oil tank through the one-way valve, so that the time needed for adjusting the pressure difference between the interior and the exterior of the oil tank to a safe range is shortened, and the pressure stabilizing efficiency of the oil tank pressure stabilizing system is improved.
本申请涉及一种油箱稳压系统及车辆。该油箱稳压系统包括:隔离阀,隔离阀开启时,隔离阀用于连通油箱内部和外界;单向阀,单向阀开启时,单向阀用于连通油箱内部和外界,且保证流经单向阀的流体单向流动;油箱压力传感器,设置于油箱并用于检测油箱的内部压力;控制器,用于在接收到加油申请信号后,控制隔离阀和单向阀的开闭以调整油箱内部压力,所述控制器还用于接收油箱压力传感器的信号,并在油箱内部与外界的压力差处于安全范围之内后输出安全信号以便于开启油箱。本申请油箱稳压系统通过设置连通油箱内部和外界的单向阀,使外界气体还经单向阀进入油箱内部,从而减少将油箱内外压差调整至安全范围所需时间,提升油箱稳压系统的稳压效率。
