The invention discloses a
flame-suppression explosion
relief valve, which comprises a valve body, a valve cover and a
valve seat, wherein the valve body is provided with a cavity, the valve cover is arranged at the top of the valve body, and the
valve seat is arranged at the lower part of the valve
body cavity; the valve
body cavity is further provided with a
powder storage bag, a rupture disk, a pressure rod, a spring seat and a spring; the
powder storage bag is arranged at the top of the valve
body cavity, is folded in a zigzag shape, and stores a
powder explosion
suppressor; the rupture disk is disposed between the powder storage bag and the
valve seat, the pressure rod is vertically disposed at the top of the valve seat and located below the rupture disk, and the spring seat is disposed above the valve seat and connected with the pressure rod; the pressure rod is sheathed in the spring, which is located between the spring seat and the valve seat, and the valve body between the spring seat and the valve seat is provided with vent holes. The powder storage bag containing the explosion
suppressor is arranged in the valve body, so that the
flame-suppression explosion
relief valve has the functions of automatic exhausting, explosion suppression and explosion
flame elimination, has good explosion-proof safety performance, and can stably operate for a long time.
