防火門的主要作用就是可以讓火勢的蔓延和煙霧擴散在一定的時間內可以起到拖延和阻隔的作用，確保人員疏散。

The main function of fire doors is to delay and block the spread of fire and smoke for a certain period of time, ensuring personnel evacuation.

1、由于火災發生時(shi)人們不可能(neng)隨手關(guan)門，故防(fang)火門必須自動關(guan)閉，須設(she)自動閉門器。目前，自動閉門器分為油(you)壓(ya)式(shi)和彈(dan)(dan)簧式(shi)兩類，用于防(fang)火門者多為單(dan)(dan)向(xiang)開(kai)啟的油(you)壓(ya)式(shi)門頂彈(dan)(dan)簧及單(dan)(dan)管式(shi)彈(dan)(dan)簧合(he)頁(ye)。

1. Due to the inability of people to close the door casually during a fire, fire doors must automatically close and automatic door closers must be installed. At present, automatic door closers are divided into two types: hydraulic and spring type. The ones used for fire doors are mostly one-way hydraulic door top springs and single tube spring hinges.

需(xu)要(yao)(yao)注意(yi)的是，不要(yao)(yao)誤將這類自動閉門器裝在(zai)受火面的一邊，以(yi)免在(zai)火災時遭(zao)高溫(wen)破壞。平時要(yao)(yao)保證(zheng)自動閉門器靈敏有效，一旦損壞要(yao)(yao)及(ji)時更換。

It should be noted that such automatic door closers should not be mistakenly installed on one side of the fire surface to avoid being damaged by high temperatures during a fire. Normally, it is necessary to ensure that the automatic door closer is sensitive and effective. If it is damaged, it should be replaced in a timely manner.

2、平時(shi)處(chu)于開(kai)啟狀態下(xia)的防火(huo)門，必須(xu)設(she)固(gu)定裝置(zhi)，以(yi)便于通行。一般設(she)有電(dian)磁(ci)釋(shi)放開(kai)關或易熔(rong)合金(jin)把(ba)門固(gu)定在兩邊墻上，火(huo)災(zai)時(shi)斷電(dian)失磁(ci)(或通電(dian)生磁(ci)而將鎖(suo)舌吸開(kai))或燒熔(rong)合金(jin)，門則(ze)在彈(dan)簧(huang)作用(yong)下(xia)自動關閉。

2. Fire doors that are usually in an open state must be equipped with fixed devices for easy passage. Generally, there is an electromagnetic release switch or a fusible alloy to fix the door to the walls on both sides. In the event of a fire, the door will automatically close under the action of a spring when the power is cut off and demagnetized (or the lock tongue is pulled open due to electrification) or the alloy is melted.

值(zhi)得注意的(de)(de)是(shi)，不能采(cai)用掛鉤或門卡將防火(huo)門固定，因為發生火(huo)災時慌亂中的(de)(de)人們是(shi)不會把門關(guan)上的(de)(de)，這樣就會導(dao)致(zhi)煙(yan)火(huo)竄入，從而使(shi)走道和樓梯間(jian)失去疏散的(de)(de)作用。

It is worth noting that hooks or door clips cannot be used to secure fire doors, as panicked people will not close the doors in the event of a fire, which can lead to fireworks entering and rendering the corridors and stairwells ineffective in safe evacuation.

3、專作疏(shu)散的(de)樓梯(ti)間(jian)防(fang)火(huo)門，平時為了防(fang)盜在使用中往往被鎖上。為了既防(fang)火(huo)又防(fang)盜的(de)問題，此類(lei)防(fang)火(huo)門可采用電磁門鎖。

3. The stairwell fire doors designed for evacuation are often locked during use to prevent theft. To solve the problem of both fire and theft prevention, electromagnetic door locks can be used for such fire doors.

本樓人員可(ke)用(yong)鑰匙開啟進(jin)入(ru)，火(huo)災時由煙感器聯動或消(xiao)防控(kong)制(zhi)室遠距(ju)離控(kong)制(zhi)而接(jie)通電(dian)路，鎖舌則在磁力作(zuo)(zuo)用(yong)下縮回，門(men)便(bian)可(ke)被推開。也可(ke)設置(zhi)簡(jian)便(bian)的機械(xie)式推杠門(men)鎖，任(ren)何時候從里面(mian)只要(yao)(yao)一(yi)推門(men)便(bian)可(ke)打(da)開，人出去后門(men)便(bian)回彈關(guan)上，從外面(mian)進(jin)入(ru)則要(yao)(yao)用(yong)鑰匙開啟，故可(ke)防止作(zuo)(zuo)案者(zhe)進(jin)入(ru)樓內。

Personnel in this building can enter with a key. In case of a fire, the circuit is connected through the linkage of smoke detectors or remote control from the fire control room. The lock tongue is retracted under the action of magnetic force, and the door can be pushed open. A simple mechanical sliding door lock can also be set up, which can be opened at any time by simply pushing the door from the inside. The back door will rebound and close when people leave, and when entering from outside, a key must be used to open it, so it can prevent criminals from entering the building.
