Memory alloy fire damper fully automatic actuator

The fully automatic actuator of the memory alloy fire damper is a fire safety device that combines the characteristics of the memory alloy and the automation control technology. The following is a detailed analysis of the actuator:

1. Overview

The fully automatic actuator of the memory alloy fire damper is mainly used to control the opening and closing of the fire damper, especially in emergency situations such as fire, it can automatically respond and close the valve to prevent the spread of fire and toxic smoke. The actuator uses the special properties of the memory alloy to deform at a specific temperature, thereby driving the valve to close.

2. Working principle

Memory alloy characteristics: Memory alloy has the characteristic of shape memory effect at a specific temperature. When the temperature reaches the preset value, the alloy will return to its original shape or produce a predetermined deformation.

Temperature sensing: The actuator has a built-in temperature sensing element (such as fusible metal sheet or shape memory alloy) to monitor the temperature of the surrounding environment.

Automatic closing: When the ambient temperature reaches the preset critical value (such as 280℃), the memory alloy deforms, driving the actuator to act, so that the fire damper is quickly closed.

Linkage control: Some fully automatic actuators also have the linkage function with the fire protection system, and can perform corresponding actions after receiving the signal from the fire control center.

3. Functional features

Automatic response: It can automatically close the valve in emergency situations such as fire without manual intervention.

High reliability: It is made of high-quality materials such as memory alloys, and has high reliability and durability.

Easy maintenance: The actuator has a simple structure and is easy to maintain and replace.

Strong safety: It can effectively prevent the spread of fire and toxic smoke and protect the lives and property of personnel.

4. Application scenarios

The fully automatic actuator of memory alloy fire dampers is widely used in ventilation and air-conditioning systems and smoke exhaust systems of various buildings, such as high-rise buildings, underground buildings, industrial plants, etc. In these places, the actuator of the fire damper needs to be able to respond quickly and close the valve to prevent the spread of fire and toxic smoke.

5. Conclusion

The fully automatic actuator of memory alloy fire dampers is an efficient and reliable fire safety equipment that can automatically close the valve in emergency situations such as fire to protect the lives and property of personnel. With the continuous development of fire protection technology, the fully automatic actuator of memory alloy fire dampers will be applied and promoted in more fields.
