Where should the fire damper be installed in the air conditioning equipment?

For the installation and maintenance of fire damper, such knowledge will often be popularized to employees. The installation of fire damper is a skill that must be learned by air conditioner installation personnel. There are many points to note in installing fire damper, which is not as simple as people imagine.

The fire damper is installed on the delivery and return air pipes of the ventilation and air conditioning system. It is normally opened. When the gas temperature reaches 70 in the pipeline, the fuse piece is blown off, and the valve automatically closes under the action of torsional spring force. It can meet the requirements of fire stability and fire integrity in a certain time, and the valve acts as a smoke blocking fire. When the valve is closed, the output signal is turned off.



What kind of environment is the fire damper normally used?

What kind of environment is the fire damper normally used?

Air supply, including ventilation, such as fresh air and exhaust, has a wide range, such as factory workshop, production site air, due to the production of harmful gases need to be discharged from the outside, and the need for outdoor air to the room. At this time, we need to use large and low pressure air conveying pipes. The spiral fire damper is very suitable. In general, galvanized iron pipes are used, corrosive stainless steel pipes are used in special damp places.

Send a cold wind. The most common is the central air conditioning pipeline, this piping needs to add the heat preservation material. The spiral fireproof valve can be attached with thermal insulation material and looks beautiful.

The smoke exhaust fire damper is mainly used for ventilation pipes and air conditioning systems, and is usually in a "normally open" state. When the air temperature reaches 70 degrees centigrade, the fuses are automatically closed by the fuses in the valves.

The smoke vent and smoke exhaust valve are mainly installed on the pipe of the exhaust system or installed at the suction inlet of the fire exhaust fan. The professional circular fire-fighting valve is provided with a fair price and is usually closed. When the fire valve of Neijiang is in fire, the smoke can be automatically opened through the linkage.



There is no pneumatic fire valve for gas pipe network rescue system. 50116-98 article 6.3.4.3 of China requires: "during the period of extension 1, the professional production of CCC fire damper is complete in specifications, and the fire doors and windows should be shut down automatically, the ventilation and air conditioning systems should be shut down, and the fire fighting valves of the relevant parts should be closed." This requires that in the pipe network gas saving system, the performance of the fire control valve with near control smoke at low price is stable, and it is necessary to connect the equipment with the pneumatic fire damper and the fire control equipment.

There is no remote control when air supply and exhaust smoke are combined with air duct. In some buildings, basement and parking lots are selected to supply air and smoke exhaust. When the air duct is used for ventilation and smoke exhaust, it is found that the cut-off valve in front of the blower and smoke exhauster can only be manually operated at the scene, and the remote control of the control room can not be realized. Once a fire breaks out, it is necessary for people to go to the scene to close the cut-off valve before the fan, which will directly affect the exhaust system. It is suggested that its cut-off valve increase the remote control function.
