The role of fire dampers is becoming more and more important, most of which need to rely on manual detection. Manually opening the smoke exhaust valve is usually in a normally closed state, and the flexibility is not high. If it is not found in time, it is easy to cause irreparable losses. The design of automatic smoke exhaust fire dampers is based on the above rigid smoke exhaust fire dampers. So, what is an automatic smoke exhaust valve? What is the difference between the installation and use of smoke exhaust valve? Today I will explain it in detail.

自動(dòng)排煙防火閥的運(yùn)行不需要人工干預(yù)，平時(shí)不開啟。但當(dāng)發(fā)現(xiàn)火災(zāi)時(shí)，會(huì)自動(dòng)打開排煙系統(tǒng)進(jìn)行排煙防火。與普通防火阻尼器相比，它能更快地探測(cè)和控制火災(zāi)。其次，也是重要的，需要自動(dòng)排煙防火閥配合感煙探測(cè)器和自動(dòng)報(bào)警系統(tǒng)工作，更適合機(jī)械排煙場(chǎng)所。

The operation of automatic smoke exhaust fire damper does not require manual intervention, and it is not opened at ordinary times. However, when a fire is found, the smoke exhaust system will be automatically opened for smoke exhaust and fire prevention. Compared with ordinary fire damper, it can detect and control fire faster. Secondly, it is also important that automatic smoke exhaust fire dampers work with smoke detectors and automatic alarm systems, which are more suitable for mechanical smoke exhaust places.

自動(dòng)排煙防火擋板安裝在排煙管道上，既能排煙又能防火。

The automatic smoke exhaust fire damper is installed on the smoke exhaust pipe, which can both smoke exhaust and fire prevention.

在安裝時(shí)，為了使其更好的工作，它會(huì)選擇安裝在排煙管道上，這樣排煙防火風(fēng)門既能具有排煙閥的功能，又能具有防火風(fēng)門的功能。排煙閥能在開始時(shí)迅速排走室內(nèi)煙霧，為室內(nèi)人員提供良好的逃生環(huán)境。一旦管道內(nèi)溫度高于280℃，防火閥就開始起作用，自動(dòng)關(guān)閉閥門，避免火災(zāi)蔓延。

During installation, in order to make it work better, it will be installed on the smoke exhaust pipe, so that the smoke exhaust fire damper can not only have the function of smoke exhaust valve, but also have the function of fire damper. The smoke exhaust valve can quickly exhaust the indoor smoke at the beginning, providing a good escape environment for indoor personnel. Once the temperature in the pipeline is higher than 280 ℃, the fire damper will start to work and automatically close the valve to avoid the spread of fire.

隨著人們安全意識(shí)的逐步提高，對(duì)排煙和防火擋板的要求也越來越高。大型寫字樓、商場(chǎng)及部分地鐵建筑均設(shè)有感煙探測(cè)器及自動(dòng)報(bào)警系統(tǒng)，為自動(dòng)排煙及防火擋板的廣泛應(yīng)用提供了有利條件。

With the gradual improvement of people's safety awareness, the requirements for smoke exhaust and fire dampers are also getting higher and higher. Large office buildings, shopping malls and some subway buildings are equipped with smoke detectors and automatic alarm systems, which provide favorable conditions for the wide application of automatic smoke exhaust and fire dampers.
