Main technical parameters
1. The gas static pressure difference of 1000Pa ± 150pa shall be maintained on both sides of the smoke exhaust valve blade, and the smoke leakage per unit area shall not be greater than or equal to 700m3 / m2 h; 2. Control voltage: DC24V; 3. Full time resistance coefficient: < 0.5.
Structure: 1 Main components: decorative air outlet, valve body, blade and actuator;
2. The smoke exhaust is a wide plate flange, and the non smoke outlet is a decorative air outlet; 3. Thickness of smoke exhaust valve body; L=220mm;
4. Thickness of exhaust outlet valve body: l = 250mm (including air outlet plate).
Performance; It is usually closed and meets the requirements of air leakage. In case of fire or need for smoke exhaust, the machine shall be manually disordered and electrically opened to play the role of smoke exhaust. When the electric phosphorous iron in the actuator is energized, the valve will open automatically and output the high opening electrical signal. Deep door
It can be opened manually and reset manually after the valve acts.
