Problems solved by technology

[0003] However, when the existing smoke exhaust fire dampers are in the closed state, the blades of the fire dampers are mostly integrated. During the rapid closing process, the blades will directly contact the inner wall of the valve, which will cause damage to the blades and cause joints to be damaged. Air leakage area is prone to

Abstract

The invention relates to a smoke exhaust fireproof valve. The smoke exhaust fireproof valve comprises a valve body and a fireproof blade assembly arranged in the valve body, and further comprises two sealing seats oppositely arranged on the inner side wall of the valve body, the fireproof blade assembly is arranged between the two sealing seats, and sealing grooves are formed in the sealing seats. Telescopic sealing parts used for being inserted into the sealing grooves are arranged on the side, close to the sealing seats, of the fireproof blade assembly. The traditional contact mode of blades and a valve body when the blades are in a closed state is improved, hard contact type closing is converted into soft contact type closing, rollers roll on the arc-shaped side edges of the sealing seats and cooperate with stretching and retracting of first springs, and damage to fireproof blades can be reduced in the closing process; and the service life of the fireproof blades is prolonged, due to soft contact type closing, through matched use of the sealing seats and the sealing parts, in the closing process of the fireproof blades, the sealing effect on the closing position of the valve body is achieved, and the fireproof effect of the fireproof blades on high-temperature smoke is improved.

Description

technical field [0001] The invention relates to the technical field of fire fighting equipment, in particular to a smoke exhaust fire damper. Background technique [0002] The fire protection system is an indispensable component in building construction. When a fire occurs in a building, the fire protection system can play a good role in fire prevention and fire resistance, and can prolong the escape time for people. Among them, the smoke exhaust damper is used as a fire system to exhaust smoke The important components in the process are usually open. When a fire occurs, the smoke exhaust will be turned on. When the temperature of the flue gas in the exhaust pipe reaches 280 degrees, it will be closed. It will have a good fire prevention effect when the flue gas reaches a higher temperature. To prevent the fire system from contributing to the effect of smoke in the event of an oversized fire. [0003] However, when the existing smoke exhaust fire dampers are in the closed s...
