Using the shock wave generated during an explosion to push a floating ball and block the flames and shock waves generated by the explosion, it is commonly used for explosion isolation on the clean air outlet side with explosion sources, trace dust transport, and dust collectors on both sides. Under normal working conditions, the floating ball is in the middle position of the valve. When an explosion occurs, the shock wave of the explosion pushes the sealing strip between the floating ball and the valve body to close. At the same time, the explosion-proof valve is locked by the locking mechanism to prevent the propagation of flames and shock waves generated by the explosion.

Working principle
In normal operation, the medium flows around the floating ball. When an explosion occurs, the pressure wave pushes the floating ball to the sealing strip of the valve body. In the closed state, the valve is locked to prevent the propagation of flames and pressure waves. In normal operation, the medium flows around the floating ball.
