The invention discloses a pressure relief valve for an automobile. The pressure relief valve for the automobile comprises a valve body and a flow stop cover, wherein the flow stop cover is in a frametype and located at the side, used for enabling internal airflow to flow out, of the valve body, and surrounds the circumference of the valve body; and the flow stop cover comprises a first guide partlocated at the bottom of the valve body and capable of reflecting the airflow to the periphery, a water leakage port is formed in the bottom of the first guide part, and the water leakage port is used for draining accumulated water in the first guide part. According to the pressure relief valve for the automobile and the automobile, the frame-type flow stop cover surrounding the circumference ofthe valve body is arranged at the side used for enabling the internal airflow to flow out, of the valve body, the first guide part capable of reflecting the airflow to the periphery is arranged at theposition, located at the bottom of the valve body, on the flow stop cover, and due to a half-surrounded design, the problems of wind noise and road noise or direct transmission for exhaust airflow into the automobile through the pressure relief valve for the automobile can be prevented in an acceleration process of the automobile; and the pressure relief valve for the automobile is light in deadweight and occupies less space, so that the driving feeling in the automobile is greatly improved.

    本发明公开了一种车用泄压阀,包括阀体和挡流罩;挡流罩为框架式,位于阀体用于使内部气流流出的一侧,挡流罩围绕于阀体的周边;挡流罩包括位于阀体底部的能够将气流向外围反射的第一导向部,第一导向部的底部设有漏水口,漏水口用于使第一导向部内的积水排出。本发明公开的车用泄压阀及汽车,通过在阀体上使内部气流流出的一侧设置围绕于阀体周边的框架式挡流罩,并在挡流罩上位于阀体底部位置设置能够气流向外围反射第一导向部,半包围式设计既能够起到车辆加速过程中,防止风噪、路噪或排气气流通过车用泄压阀直接传入车内的问题,本发明公开的车用泄压阀自重轻,占用空间小,大幅度提升了车内行驶质感。
