The invention discloses an exhaust pressure release valve, a vehicle and an exhaust control method. The technical problem that in the prior art, an exhaust valve blade flaps a valve body to generate abnormal sound is solved. The exhaust pressure release valve comprises a pressure release valve body and a driving structure. The pressure release valve body is provided with a through pressure release channel. And the control blade is rotationally connected with the pressure release valve body. The driving structure comprises a driving piece, a rotating wheel, a shifting block and a control frame. The driving part is used for driving the rotating wheel to rotate along the axis. The shifting block and the rotating wheel are eccentrically arranged, the control frame is matched with the shifting block, when the rotating wheel rotates, the shifting block shifts the control frame to move, and the control frame is rotationally connected with the control blade. When the control frame moves, the control blades are driven to rotate, and the opening degree of the pressure relief channel is controlled. According to the exhaust pressure release valve, the angle of the control blade is controlled through the driving piece, the position of the control blade is stable and controllable, and the situation that the control blade flaps the pressure release valve body along with shaking of a vehicle body can be effectively avoided.
本申请公开了一种排气泄压阀、车辆以及排气控制方法,解决现有技术排气阀叶片会拍打阀体而产生异响的技术问题。排气泄压阀包括泄压阀本体和驱动结构。泄压阀本体设置有贯通的泄压通道。控制叶片与泄压阀本体转动连接。驱动结构包括驱动件、转动轮、拨块和控制架。驱动件用于驱动转动轮沿其轴心线转动。拨块与转动轮偏心设置,控制架与拨块配合,在转动轮转动时,拨块拨动该控制架移动,控制架与控制叶片转动连接。在控制架移动时带动控制叶片转动,以及控制泄压通道打开的大小。本申请公开的排气泄压阀利用驱动件对控制叶片的角度进行控制,控制叶片的位置为稳定可控,可以有效避免出现控制叶片随车身的抖动而拍打泄压阀本体的情况出现。
