The invention provides a vehicle and an in-vehicle air pressure regulating valve thereof. The in-vehicle air pressure regulating valve comprises a valve body with a valve port and a soft valve plate used for sealing the valve port, the upper end of the valve plate is connected to the valve body, the lower end of the valve plate is a free end, the valve plate is a turnover valve plate which is pushed by airflow to swing outwards to make the valve port open when the difference value between the air pressure inside the vehicle and the air pressure outside the vehicle reaches a critical value, andswings inwards by means of self-weight to seal the valve port when the difference value between the air pressure inside the vehicle and the air pressure outside the vehicle is smaller than the critical value, the turnover valve plate is obliquely arranged from top to bottom and from inside to outside, supporting ribs forming an exhaust grid are arranged at the valve port, and the supporting ribsare provided with a rib supporting face which supports the turnover valve plate upwards to prevent the turnover valve plate from collapsing when the turnover valve plate seals the valve port. The supporting ribs are arranged to prevent the middle position of the turnover valve plate from collapsing, and then the situation that the turnover valve plate is not tightly sealed due to uneven deformation of the turnover valve plate is prevented.
本发明提供了一种车辆及其车内气压调节阀,车内气压调节阀包括具有阀口的阀体和用于封闭所述阀口的软质的阀片,所述阀片的上端与所述阀体相连,下端为自由端,所述阀片为当车内气压与车外气压差值达到临界值时被气流推动外摆以让开阀口、车内气压与车外气压差值小于临界值时依靠自重内摆以封闭阀口的翻转阀片,所述翻转阀片由上至下且由内至外倾斜布置,所述阀口处设置有形成排气格栅的支撑肋条,所述支撑肋条具有当翻转阀片封闭所述阀口时向上支撑翻转阀片以防止翻转阀片塌落的肋条支撑面。通过设置支撑肋条,能够防止翻转阀片的中间位置塌落,进而防止由于翻转阀片的不均匀变形而导致翻转阀片密封不严的情况出现。
