Application scope and cleaning of fire damper equipment

　　It is known that fire damper equipment is a flow control valve installed on air conditioning and ventilation ducts. The blade closing angle is controlled by a motor. It is widely used in civil residential buildings, industrial site ventilation and air conditioning, air purification and other projects, and is also suitable for occasions where manual operation is inconvenient. So, let's learn about the application scope and cleaning of fire damper equipment.

　　Based on the manually opened multi-leaf regulating valve, the fire damper equipment changes the steering wheel operation to ZAJ-2 type electric actuator operation. The actuator controls the air volume by operating the closing angle of the blade through the connecting rod mechanism. Pressing the hand switch can adjust the angle to any position, so that the regulating valve can move at the required angle. According to the actual needs, the position of the switch connecting seat before the regulating valve starts must correspond to the position of the observation hole. Fire damper equipment is suitable for high-rise buildings, underground buildings, tunnels, drying rooms and other ventilation and high-temperature smoke exhaust. Under the condition of 280°C high temperature, it can continuously operate for more than 30 minutes, and under the condition of 100°C medium temperature, it can continuously operate for 20 hours/time without damage, which is an ideal fire-fighting facility.

　　I. Application scope of fire damper equipment:

　　According to the requirements of civil residential buildings, select the above different smoke exhaust valves and vents.

　　1. The main control parameters for the selection of fire damper equipment are specifications, etc.

　　2. Fire damper equipment is suitable for ventilation and air conditioning systems. Except for fire dampers used in public building kitchen smoke exhaust systems, the operating temperature is 150°C, and the operating temperature of fire dampers used in general ventilation and air conditioning systems is 70°C.

　　3. Suitable for ventilation, air conditioning or smoke exhaust system pipelines, basic functions and application scope.

　　4. When selecting valves, please pay attention to the functions of the valves. There are requirements such as normally open, normally closed, automatic closure, manual closure, manual reset, signal output, and remote control.

　　5. When the valve is linked with the blower, please use a double micro-switch device.

　　6. The valve body blades are made of steel plates with a thickness of 2-6mm, the valve body is made of non-combustible materials, the rotating parts are made of corrosion-resistant metal materials, and the rotation is flexible. The thickness of the valve shell should be controlled below 2mm. Easily melted parts must meet the approval of the fire department.

　　II. Application and cleaning of fire damper equipment

　　The fire damper equipment is normally closed and can only be automatically opened after the indoor smoke reaches a certain concentration, and automatically closes at 280°C.

　　Fire damper equipment is mainly used in ventilation and air conditioning systems. The general equipment of fire and smoke dampers is located in the fire-prevention zones of ventilation and air conditioning system rooms. It is a 70°C fire damper, which is often opened, and automatically closes when the smoke temperature in the pipeline reaches 70°C. The operation method is automatic.

　　Always open on the pipeline for long-term ventilation. The equipment is located at the pipeline base, 70°C, and can block the pipeline in case of fire, achieving two effects. First, it does not supply air to the fire scene, avoiding combustion. Second, it prevents the fire source from spreading to other areas from the pipeline. It will automatically close when a fire occurs.
