The invention provides a pressure release valve for adjusting the pressure of a compartment, which is characterized by comprising a shell internally provided with a channel, the channel is configured to enable the compartment to be in fluid communication with the external atmosphere, and the channel is provided with a channel opening; the channel opening cover is configured to be capable of moving between an opening position and a closing position, when the channel opening cover is located at the opening position, the channel opening is opened, when the channel opening cover is located at the closing position, the channel opening is closed, and the executing mechanism is configured to drive the channel opening cover. The channel opening cover is enabled to move between the opening position and the closing position. According to the pressure release valve, the signal information of the pressure, the wading and the dust density in the automobile is obtained, a traditional rotary opening mode of the pressure release valve is converted into a linear opening mode through motor driving, motorization of the pressure release valve is achieved, noise outside the automobile is reduced, and the waterproof and dustproof performance of the pressure release valve is improved.
