Main technical parameters
1. Tunnel air volume (pressure difference 300pa): ≤ 700m3 / m2 h;
2. Control voltage: DC24V;
3. Contact capacity of microswitch: AC380V ≤ 0.5A;
4. Full time resistance coefficient: < 0.5.
Structure: 1 Main components: decorative air outlet, valve body, blade and actuator;
2. The smoke exhaust valve is a common plate flange, and the smoke exhaust 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 panel);
5. The length of steel wire rope shall not exceed 6m.
Performance; Normally closed, the smoke detector sends smoke through the control center when the fire turtle
The electrical signal (DC24V) is sent out, the electromagnetic iron in the actuator is energized, the valve opens automatically, and the opening electrical signal is output. The valve can be opened manually from a long distance and reset manually from a long distance after the valve acts.
