Fire damper

Installed on the air supply and return pipes of ventilation and air conditioning systems, it is usually open. When the smoke temperature in the pipe reaches 70 ℃, it is closed when the smoke temperature in the pipe reaches 70 ℃, and it can meet the requirements of smoke leakage and fire resistance integrity within a certain period of time. Valves that act as smoke isolation and fire resistance. Fire valve is generally composed of valve body, blade, actuator and temperature sensor and other components.

Product Details

1. fire valve product introduction:
Installed on the air supply and return pipes of ventilation and air conditioning systems, it is usually open. When the smoke temperature in the pipe reaches 70 ℃, it is closed when the smoke temperature in the pipe reaches 70 ℃, and it can meet the requirements of smoke leakage and fire resistance integrity within a certain period of time. Valves that act as smoke isolation and fire resistance. Fire valve is generally composed of valve body, blade, actuator and temperature sensor and other components.
2. 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. fire valve performance:
Normally open, temperature sensor operating temperature is 70 ℃
(I) temperature sensor control: ① fire valve with temperature sensor control mode, make it automatically closed;
② temperature sensor action performance and non-action performance: the temperature sensor in the fire valve in the 73 ℃ ± 0.5 ℃ constant temperature water bath within 1min action, and in the 65 ℃ ± 0.5 ℃ constant temperature water bath within 5min no action.
(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.
