Fire damper spring

la source:Précision Qianye temps:2022-9-14
Fire dampers are valves that are used to block the passage of smoke and flame from fires and meet the requirements of fire resistance stability and integrity within a certain period of time. In order to minimize the loss caused by fire, it is necessary to take effective fire and smoke prevention measures to control the spread of fire while the fire damper is ventilated. Reasonable settings in the air conditioning and smoke exhaust system play an important role.

The operation of fire dampers is simple: when the temperature of a room or space rises above a threshold limit, they close to prevent the fire from spreading. Fire dampers have fuses and can be selected according to the required temperature. Once this temperature is reached, the damper closes.

   The damper itself can be electric, pneumatic or manually set. In electrically and pneumatically actuated dampers, a fuse releases and cuts off the operating voltage of the spring-return motor, causing the spring to close the damper blades. After replacing the fuse and re-establishing the operating voltage of the motor, the fire damper opens automatically. In a spring-operated damper, a fuse release allows the spring to close the damper blade. After replacing the fuse, the fire damper must be manually reset to the open position.

Design of fire damper spring:

  The advantage of the spring designed by Qianye is as follows:

Although Qianye precision can not directly prevent the initial occurrence of fire, we have created customized springs for the life support function of fire dampers. In turn, our spring-loaded dampers provide ventilation and prevent the spread of smoke and fire. Qianye is a global supplier of fire damper spring solutions. No matter what type of building, Qianye precision recognizes that the ultimate application of our springs is to save lives.

Précision Qianye‘s mission is to guarantee the precision of the best function of your products. We design springs that will provide high quality, performance and safety for people and the buildings they live in. With more than ten years of industry service experience, it has become a well-known brand distributor in China. We sincerely suggest that customers can obtain consulting services from our R&D engineers in the early stage of product introduction and development.
