七氟丙烷灭火系统以全淹没方式灭火、独立成套、可移动的灭火设备，可以与消防控制中心相连接，由火灾报警灭火控制器驱动实施自动灭火。那么七氟丙烷灭火系统安装需要注意哪些地方？下面川消小编为您解说。

The heptafluoropropane fire extinguishing system is an independent complete set of movable fire extinguishing equipment that can extinguish fire in a totally submerged manner. It can be connected to the fire control center and is driven by the fire alarm fire extinguishing controller to implement automatic fire extinguishing. What should be paid attention to in the installation of heptafluoropropane fire extinguishing system? Now let's explain it to you.

一、关于七氟丙烷泄压口的安装:

1、 Installation of heptafluoropropane pressure relief port:

安装在灭火防护区墙体上，平时呈关闭状态，当气体灭火系统对防护区实施灭火时，泄压装置在一定压力下自动打开泄压，确保防护区；当压力降低到一定值时，泄压装置自动关闭。可以保证防护区的密闭性，满足灭火的需要，同时确保防护区。

It is installed on the wall of the fire protection area and is normally closed. When the gas fire extinguishing system extinguishes the fire in the protection area, the pressure relief device automatically opens under a certain pressure to relieve pressure, so as to ensure the safety of the protection area; When the pressure drops to a certain value, the pressure relief device will automatically close. It can ensure the airtightness of the protection area, meet the needs of fire fighting, and ensure the safety of the protection area.

二、七氟丙丙烷泄压口的选型:

2、 Model selection of heptafluoropropane pressure relief port:

泄压装置的选型：根据灭火系统设计规范，可计算出防护区泄压口的面积，根据计算出的面积可选用不同型号的一个或多个泄压装置。

Model selection of pressure relief device: according to the design specification of fire extinguishing system, the area of pressure relief port in the protection area can be calculated, and one or more pressure relief devices of different models can be selected according to the calculated area.

三、七氟丙烷泄压口的动作原理:

3、 Operation principle of heptafluoropropane pressure relief port:

当火灾发生时，气体灭火系统启动，喷放灭火剂灭火，防护区内的压力随之升高。当压力上升设定值时，泄压执行机构迅速将叶片从关闭状态转变为开启状态，防护区压力释放，使防护区结构不破坏。当防护区压力下降设定值以下时，泄压机构复位，叶片关闭。

In case of fire, the gas fire extinguishing system will be started, and the fire extinguishing agent will be sprayed to extinguish the fire. The pressure in the protection area will increase accordingly. When the pressure rises to the set value, the pressure relief actuator quickly changes the blade from closed state to open state, and the pressure in the protection zone is released, so that the structure of the protection zone will not be damaged. When the pressure in the protection area drops below the set value, the pressure relief mechanism resets and the blades close.

四、七氟丙烷泄压口安装和使用注意事项规范要求：

4、 Precautions for installation and use of heptafluoropropane pressure relief port:

泄压装置宜设在外墙上，若用于七氟丙烷灭火系统，应设于防护区净高2/3以上

The pressure relief device should be set on the external wall. If it is used in the heptafluoropropane fire extinguishing system, it should be set at more than 2/3 of the clear height of the protection area

此外七氟丙烷灭火系统需要设置专用的设备间，用一套或一套以上的储存装置保护一个或一个以上的防护区，采用管网将灭火剂输送到保护区的系统。还有不少事项需要提前进行了解，您可来我们网站http://www.cx-fire.com咨询！

In addition, the heptafluoropropane fire extinguishing system needs to set up a special equipment room, protect one or more protection areas with one or more storage devices, and use the pipe network to deliver the extinguishing agent to the system in the protection area.
