The 70-degree fire damper is also suitable for occasions where ventilation and air conditioning pipes are installed on the ceiling and cannot be manually reset. Fire damper manufacturers are an important part of the active system. It is installed in the field control flow path, so it is an important device to cut off the flow path when there is strong and prevent combustible fluid from leading to the fire environment. The special fire damper for fire fighting is generally made of carbon material and galvanized sheet, which is suitable for installation on the air supply and return pipes of ventilation and air conditioning systems. It's usually open. Special fire dampers for fire fighting are generally installed on the air ducts of ventilation and air conditioning systems that need to adjust the air volume, and are suitable for horizontal or straight air ducts. The special fire damper for smoke prevention and fire fighting is generally installed in the air duct of ventilation and air conditioning system. Electrical signals are needed to adjust the air volume or close the valve. A pipe for horizontal or straight air flow.

High-rise buildings and other modern buildings are equipped with ventilation, air conditioning and smoke prevention systems. In the event of a fire, the pipes in these systems will become the channels for the spread of flames and smoke. Exhaust port: It consists of exhaust valve, louver tuyere or flat tuyere, and is used in exhaust branch pipes of exhaust system and rocket system. The special fire damper for fire fighting is a valve closed by gravity and tension spring mechanism. When the flue gas temperature reaches 280℃, it can be used to achieve the purpose of smoke isolation and fire prevention.

The special fire damper for fire fighting is used on the air supply and return pipes of natural ventilation and central air conditioning system, and it is usually open. When a fire accident happens to a special fire damper, the manufacturer will automatically close the pipeline when the gas temperature reaches 70℃, and can meet the requirements of fire consolidation and fire integrity within a certain period of time, resulting in adverse effects of smoke isolation and fire resistance. Special fire dampers and smoke exhaust valves for fire fighting should be constructed in strict accordance with the drawings, and independent seismic supports should be set up to prevent the deformation of ventilation pipes at high temperature and endanger the effect of gate valves.

According to their functions, special fire dampers are divided into external fire dampers, internal fire dampers and internal cover fire dampers. Their effects and functions are completely consistent, and they are all the same system software such as engine and smoke exhaust system. The special fire damper for fire fighting shall be installed at the centrifugal fan (exhaust fan conversion board), exhaust centrifugal fan (exhaust centrifugal fan air inlet) and the smoke outlet of the special fire damper for fire fighting. The special fire damper for fire fighting is a valve method which is closed under the action of gravity and spring arrangement through the temperature control of fusible alloy. The function of special fire damper for fire fighting is: when the smoke temperature reaches 70-80 degrees, people have completely dispersed, so it is of no practical significance to smoke. But at this time, there is a fire in the flue gas, and the valve automatically closes to prevent the fire from spreading.

Open at ordinary times, and close when the smoke temperature in the smoke exhaust pipe reaches 285℃ in case of fire, so as to meet the requirements of smoke leakage and fire integrity in a certain period of time. At this time, it will play the role of smoke and fire prevention. The output signal of valve closing can be interlocked with other fire fighting equipment. Fire-fighting special fire damper: the oil circuit board consists of shell, flange, blade and its manually calibrated fire-fighting special fire damper. The adverse effect of special fire damper for fire fighting is to affect a disordered air supply and smoke exhaust system with complex pipelines.

In the pipeline of the smoke exhaust management system of mechanical equipment, it is normally open, and it is closed when the smoke temperature in the smoke exhaust pipeline reaches 280℃ in case of fire accident. The gate valve can meet the requirements of smoke leakage and fire prevention integrity rate, and has the functions of smoke isolation and fire prevention. Some parts of fire damper manufacturers are composed of oil circuit board, blade, actuator and temperature sensor. Installed on the pipeline of mechanical smoke exhaust system, it is normally open and automatically closed when the temperature reaches 280℃ in case of fire, which can release smoke and play the role of fire extinguishing.

When the ventilation and air conditioning system of each fire zone in the building is set independently, the joint between the horizontal air duct and the vertical main pipe may not be set with a special fire damper; The kitchen oil fume exhaust pipe is set as a special fire damper for fire control at 150℃, that is, it will automatically close when the temperature reaches 150℃. Different from the fire smoke exhaust valve, it does not automatically fuse at 280℃, that is, it only smokes smoke and has no fire prevention effect. The special fire damper for fire fighting is a kind of gate valve, which is used to block smoke and fire in the fire prevention area, and to consider the fire prevention reliability and meet the fire protection requirements in a certain period of time.

The 70-degree fire damper is also suitable for occasions where ventilation and air conditioning pipes are installed on the ceiling and cannot be manually reset. Fire damper manufacturers are an important part of the active system.
