Smoke exhaust fire damper

Installed on the pipe of the mechanical smoke exhaust system, it is usually open. When the smoke temperature in the smoke exhaust pipe reaches 280 ℃, it will be closed when the temperature reaches ℃, and it can meet the requirements of smoke leakage and fire resistance integrity within a certain period of time. The valve has the function of smoke isolation and fire retardant. Smoke fire valve is generally composed of valve body, blade, actuator and temperature sensor.

Product Details

1. smoke fire valve product introduction:
Installed on the pipe of the mechanical smoke exhaust system, it is usually open. When the smoke temperature in the smoke exhaust pipe reaches 280 ℃, it will be closed when the temperature reaches ℃, and it can meet the requirements of smoke leakage and fire resistance integrity within a certain period of time. The valve has the function of smoke isolation and fire retardant.
Smoke fire valve is generally composed of valve body, blade, actuator and temperature sensor.
2. smoke fire valve function:
Manual air volume adjustment, manual control to close or open the valve, manual reset, electric closing, temperature sensor control automatic closing, valve closing position signal feedback function, output passive switch signal.
3. smoke fire valve performance:
Normally open, temperature sensor operating temperature is 280 ℃
(I) temperature sensor control: ① fire valve with temperature sensor control mode, make it automatically closed;
② temperature sensor performance and non-action performance: the temperature sensor in the smoke exhaust fire damper operates within 2min in a constant temperature oil bath of 285 ℃ ± 2 ℃, but does not operate within 5min in a constant temperature oil bath of 250 ℃ ± 2 ℃.
(II) manual control: with manual closing mode, convenient, flexible and reliable operation.
(III) electric control:
3-1 rated voltage: DC24V 3-2 rated current: 0.7A or less
3-3 action torque: 10N.m 3-4 reset mode: manual reset, electric reset
(IV) insulation performance: the insulation resistance between the external charged terminal and the valve body is greater than 20MΩ at room temperature.
