According to different materials, it is divided into two types: pendulum type (also known as hanging plate type) and rubber tube type. The main body is made of steel structure and will automatically close instantly when subjected to a nuclear explosion shock wave. Users can choose the appropriate material according to their own needs. The explosion - proof flap is composed of multiple components, and a lock - page mechanism for the explosion - proof flap is required when using the explosion - proof flap.
