Explaining the Management Matters of Explosion-Proof Fireproof Valves

The explosion-proof fire damper consists of an integral frame and several valve blades housed within it. The frame is fixed with a fusible element and an explosion-proof actuator. Each blade end features a semi-circular reinforcing rib, with a reinforcing plate at the rib location, which also has a reinforcing rib opposite to the blade's rib direction. The two ends of the blade are equipped with sealing spring plates, and the ends of the blade shaft are fitted with copper sleeve bushes, which are supported within the blade bracket. A spring cover is added between the valve blade and the blade bracket.
By adding spring covers and sealing springs, the blade bracket and valve plate achieve enhanced sealing between them, as well as between the explosion-proof fire valve plates. The sealing spring material at the contact point of the valve plates is copper alloy, while the spring cover material at the upper and lower end faces of the valve plates in contact with the blade bracket is also copper alloy. The contact point between the blade shaft and the blade bracket is fitted with a copper sleeve, and an explosion-proof actuator is also installed, endowing the entire explosion-proof fire valve with explosion-proof capabilities.
