The quality of the fire damper actuator must be visible.

Release Time：2021-07-21

Fire valve installed in the ventilation, air conditioning system to send, return air pipe, usually open state, when the fire when the pipe smoke temperature reaches 70 degrees closed, and within a certain period of time to meet the smoke leakage and fire integrity requirements, from the role of fire.
Fire dampers, electric fire dampers and fire dampers are installed on the air supply and return air pipelines of ventilation and air conditioning systems. They are usually open. When the smoke temperature in the pipeline reaches 70 degrees, they are closed and can meet the requirements of smoke leakage and fire resistance integrity within a certain period of time. They play the role of smoke isolation and fire resistance. Fire dampers.
The actuator of the fire damper is composed of a shell, a blade adjustment mechanism, a clutch, a temperature fuse, etc. The mechanism controls the rolling of the blades through a metal fusible plate and a clutch mechanism. It adopts the principle of mechanical transmission, so it does not need electricity, gas and other energy sources. In other words, the fire damper can ensure that it can play a fire prevention role under any circumstances and will not spread resources or even cause environmental pollution.
For the phenomenon of fake and shoddy fire valve market, there are also some manufacturers in the production of jerry-built, such as the use of some tailings fire valve to produce, these are the reasons for the failure of the fire valve.
In addition, whether the installation of the fire damper is correct or not will also affect the normal use of the fire damper. It is reported that the manufacturers of the production and installation of the fire damper are different at present, and the technology of the installation engineering team is uneven, and a considerable part of the installation engineering team units do not have professional skills. They often use some compulsory means during installation, which will lead to product deformation and loss or weakening of product functions.
Fire damper: installed on the air supply and return pipelines of ventilation and air conditioning systems. The fire damper is usually open. When the gas temperature in the pipeline reaches 70 ℃ in case of fire, the fusible sheet will fuse and the valve will automatically close under the action of torsion spring force. The valve can meet the requirements of fire stability and fire integrity within a certain period of time. When the valve is closed, it will output a closing signal.
Installed on the smoke exhaust system pipeline, usually closed state, fire manual or electric open, play the role of smoke. When the flue gas temperature in the exhaust pipe reaches 280 ℃, it is closed, which can meet the requirements of fire stability and fire integrity within a certain period of time, and plays the role of smoke exhaust valve.
Shandong Xingheng Environmental Technology Group Co., Ltd. is located in Luquantun Development Zone, Dezhou, Shandong, the hometown of FRP in China. The company has Grade II qualification for fire protection facilities engineering, Grade II qualification for construction mechanical and electrical installation engineering, Grade II qualification for environmental protection engineering, and safety production license.
