Fire control valve alarm circuit device smoke exhaust fire damper material

Release Time：2021-07-15

The main purpose of the fire control valve is to set it in the ventilation and air conditioning system. The return air pipe is usually open. When the smoke temperature in the pipe reaches 70 degrees, it is closed when the smoke temperature in the pipe reaches 70 degrees, and it can satisfy the smoke leakage and fire resistance integrity requirements within a certain time, playing the role of smoke isolation and fire prevention. The main precautions for daily use of the fire control valve are:
When we use the fire control valve, this type of fire control valve will use the detector to announce the sound and light, print the alarm content, convert the fire signal sent by the detector in the area into the sound and light alarm signal, and output the signal together to the alarm controller.
When a loop gives an alarm, press the silencer button to silencer the sound. If the controller bears the alarm signal of its fire valve and other loop, it can still generate sound and light alarm, because the active fire alarm system actively monitors fires and various faults, and the system is usually under supervision. When there is no fire or fault, the user cannot know whether these active monitoring functions are in good condition.
The function of the integrated fire alarm controller is to connect several regional alarm controllers to form a system, accept the fire signal and fault signal sent by each regional alarm controller, indicate the fire area or the location of the fault area in time, and announce the sound and light alarm signal.
The materials of smoke prevention and exhaust fire damper generally include: carbon material, galvanized plate, suitable for equipment in ventilation, air dispatching system, return air pipeline, fire damper is usually opened, when the smoke temperature in the pipeline reaches 70 degrees closed, and can satisfy the smoke leakage and fire resistance integrity requirements within a certain period of time, play the role of smoke isolation and fire resistance.
The smoke exhaust fan of smoke prevention and fire prevention valve shall ensure that it can continue to operate for 30min at 280 ℃. The smoke exhaust valve (port) of electric operation function shall be opened quickly and reliably when it is 15 or 10 lower than the rated operating voltage. It is concluded that the connection terminal, the output end of the power line string into the output module is connected with the valve power line. Ventilation, air conditioning and smoke prevention and exhaust systems are provided for high-rise and other modern buildings. In case of fire, smoke expansion channel, smoke exhaust port: composed of smoke exhaust valve and louver tuyere or plate type air fire damper port, used on the special smoke exhaust branch pipe of the rocket system of smoke exhaust system.
(1) The valve is normally open. When the airflow temperature reaches 70°C, the temperature sensor acts and the valve is closed.
(2) Manual scheduling of blade opening within the range of 0 ° ~ 90 °.
(3) manual closure or manual reset.
(4) output valve closed signal, can be interlocked with other fire prevention equipment.
The general equipment of fire-fighting smoke exhaust fire-proof valve is suitable for the air duct of the ventilation and air-conditioning system with the demand for dispatching air volume, and the general equipment of smoke-proof fire-proof fire-proof fire-proof fire-proof valve is suitable for the air duct of the ventilation and air-conditioning system with the demand for dispatching air volume or the demand for electric signal control valve closed, and is suitable for the air duct of the horizontal or vertical air flow.
