防火门是常开式好还是常闭好呢？

在我们的日常生活中，经常可以看到防火门。其耐火性和隔热性能能有效防止火灾蔓延，为人员提供疏散时间。它是消防设备里面不可缺少的设备之一，所以防火门是开着好还是关着好呢？那就让济南防火卷帘门安装维修人员来去了解一下这个问题吧。

In our daily life, we often see fire doors. Its fire resistance and thermal insulation performance can effectively prevent fire spread and provide evacuation time for personnel. It is one of the indispensable equipment in the fire fighting equipment, so is it better to open or close the fire door? Let the installation and maintenance personnel of Jinan fireproof rolling shutter door know about this problem.

这要看使用防火门的类型，通常采用防火门可以分为常闭式防火门和常开式防火门。

This depends on the type of fire doors used. Generally, fire doors can be divided into normally closed fire doors and normally open fire doors.

1、防火门通常安装在人口众多的地方，如学校、购物中心、医院等。因为这些地方的人经常要在楼梯里进出，如果要安装经常关闭的防火门，肯定会很不方便。

1. Fire doors are usually installed in places with large populations, such as schools, shopping centers, hospitals, etc. Because people in these places often have to go in and out of the stairs, it would be very inconvenient to install fire doors that are often closed.

而且经常开关防火门也容易损坏，随着时间的推移不能起到防火的作用。所以这些地方通常都安装着打开的防火门，防火门通常是打开的状态，所以人们进出都会非常方便。当发生火灾时，监视器发出的报警信号可用于关闭防火门，从而隔离烟雾和火灾。

In addition, the fire door is also easy to be damaged by frequent opening and closing, and cannot play a role in fire prevention as time goes by. So these places are usually equipped with open fire doors, which are usually open, so people will be very convenient to enter and exit. In case of fire, the alarm signal sent by the monitor can be used to close the fire door, thus isolating smoke and fire.

2、常闭式防火门我们通常可以将其安装在人很少的地方。它在企业正常情况和火灾事故发生的时候他们都是处于关闭的状态，如果人想要从这边走动则需要手动推开。

2. Normally closed fire doors can be installed in places with few people. It is closed in the normal situation of the enterprise and in the event of fire accident. If people want to move from here, they need to push it away manually.

通常关闭的防火门有防止火灾蔓延的效果，这种门窗通常与监控系统一起使用，因为许多火灾案例是由于经常关闭的防火门是打开的。

Normally closed fire doors have the effect of preventing fire spread. Such doors and windows are usually used with the monitoring system, because many fire cases are caused by the fire doors that are often closed being opened.

一旦常闭式防火门处于一个长期打开的状态，发生火灾的时候我们就很容易蔓延到其他楼梯间，起不到防火的作用。并且防火门的门磁开关可以检测到门的状态，因此需要有人将防火门长时间被打开的时候，门磁开关就会导致发出控制信号，报警系统提醒以及人们生活进行关门处理。

Once the normally closed fire door is in a long-term open state, it is easy for us to spread to other staircases in case of fire, and can not play the role of fire prevention. And the door magnetic switch of the fire door can detect the status of the door, so when someone needs to open the fire door for a long time, the door magnetic switch will cause a control signal to be sent, the alarm system will remind and people's life will be closed.
