防火門的主要作用就是可以讓火勢的蔓延和煙霧擴(kuò)散在一定的時(shí)間內(nèi)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(zāi)發(fā)生時(shí)人們不可能隨手關(guān)門，故防火門必須自動關(guān)閉，須設(shè)自動閉門器。目前，自動閉門器分為油壓式和彈簧式兩類，用于防火門者多為單向開啟的油壓式門頂彈簧及單管式彈簧合頁。

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.

需要注意的是，不要誤將這類自動閉門器裝在受火面的一邊，以免在火災(zāi)時(shí)遭高溫破壞。平時(shí)要保證自動閉門器靈敏有效，一旦損壞要及時(shí)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(shí)處于開啟狀態(tài)下的防火門，必須設(shè)固定裝置，以便于通行。一般設(shè)有電磁釋放開關(guān)或易熔合金把門固定在兩邊墻上，火災(zāi)時(shí)斷電失磁(或通電生磁而將鎖舌吸開)或燒熔合金，門則在彈簧作用下自動關(guān)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.

值得注意的是，不能采用掛鉤或門卡將防火門固定，因?yàn)榘l(fā)生火災(zāi)時(shí)慌亂中的人們是不會把門關(guān)上的，這樣就會導(dǎo)致煙火竄入，從而使走道和樓梯間失去疏散的作用。

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、專作疏散的樓梯間防火門，平時(shí)為了防盜在使用中往往被鎖上。為了既防火又防盜的問題，此類防火門可采用電磁門鎖。

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.

本樓人員可用鑰匙開啟進(jìn)入，火災(zāi)時(shí)由煙感器聯(lián)動或消防控制室遠(yuǎn)距離控制而接通電路，鎖舌則在磁力作用下縮回，門便可被推開。也可設(shè)置簡便的機(jī)械式推杠門鎖，任何時(shí)候從里面只要一推門便可打開，人出去后門便回彈關(guān)上，從外面進(jìn)入則要用鑰匙開啟，故可防止作案者進(jìn)入樓內(nèi)。

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.
