The invention relates to a spring-controlled explosion-proof valve and an application principle thereof. The spring-controlled explosion-proof valve comprises a valve body and a valve element, the valve body is provided with a vent hole, the valve element is elastically penetrated in the valve body through an elastic part and is arranged on the vent hole in a pressing mode, and a limiting part used for stopping resetting of the valve element is arranged in the valve element. The spring-controlled explosion-proof valve is mainly applied to sealing containers such as a battery pack, an electriccontrol box and a storage tank, the air pressure value in the container can be effectively controlled through the elastic part, so that the air pressure in the container is kept stable; the limiting part is arranged in the valve element, when the pressure in the container rises sharply, the valve element is jacked to a certain height by the gas in the container, the limiting part is popped out andclamped on the valve body
