七氟丙烷灭火系统是一种高效能的灭火设备，其灭火剂(HFC-227ea)是一种无色、无味、低毒性、绝缘性好、无二次污染的气体；七氟丙烷灭火系统最小设计浓度为7.35%(V/V);无毒性反应的最高浓度(NOAEL)为9%(V/V)可用于有人区域。

The heptafluoropropane fire extinguishing system is an efficient fire extinguishing equipment, and its extinguishing agent (HFC-227ea) is a colorless, odorless, low toxicity, good insulation, and non secondary pollution gas; The minimum design concentration of heptafluoropropane fire extinguishing system is 7.35% (V/V); The maximum concentration of non-toxic reaction (NOAEL) is 9% (V/V) and can be used in areas with people.

七氟丙烷灭火剂具有良好的清洁性--在大气中完全汽化不留残渣、良好的气相电绝缘性，适用于以全淹没灭火方式扑救电气火灾、液体火灾或可熔固体火灾、固体表 面火灾、灭火前能切断气源的气体火灾，保护计算机房、通讯机房、变配电室、精密仪器室、发电机房、油库、化学易燃品库房及图书库、资料库、档案库、金库等场所。七氟丙烷灭火系统结构合理、动作可靠，已广泛应用于电子计算机房、档案馆、地下工程、海上采油、珍品库、电视广播中心及金融机构、政府机关等重要场所。

Heptafluoropropane fire extinguishing agent has good cleanliness - it completely vaporizes in the atmosphere without leaving residue, and has good gas-phase electrical insulation. It is suitable for extinguishing electrical fires, liquid fires, or meltable solid fires, solid surface fires, and gas fires that can cut off the gas source before extinguishing. It protects computer rooms, communication rooms, power distribution rooms, precision instrument rooms, generator rooms, oil depots, chemical flammable material warehouses, and places such as libraries, databases, archives, and vaults. The heptafluoropropane fire extinguishing system has a reasonable structure and reliable operation, and has been widely used in important places such as electronic computer rooms, archives, underground engineering, offshore oil extraction, treasure warehouses, television broadcasting centers, financial institutions, government agencies, etc.

七氟丙烷灭火系统的灭火机理为抑制作用，灭火药剂遇高温自行分解，并与空气中的氧气发生化学反应，使空气中游离氧的数量减少，阻止燃烧链，使燃烧不能继续。

The fire extinguishing mechanism of heptafluoropropane fire extinguishing system is inhibitory effect. The fire extinguishing agent decomposes on its own when exposed to high temperature and reacts chemically with oxygen in the air, reducing the amount of free oxygen in the air and preventing the combustion chain from continuing.

七氟丙烷气体灭火系统按系统组成可分为管网式、柜式、悬挂式这三类产品是市面上较为常见的，还有一类探火管式灭火装置，较少使用。

The heptafluoropropane gas fire extinguishing system can be divided into three categories based on system composition: pipe network type, cabinet type, and hanging type. These three types of products are more common on the market, and there is also a type of fire detection tube fire extinguishing device that is less commonly used.

管网式灭火系统一般由灭火剂瓶组、驱动气体瓶组、单向阀、选择阀、减压装置、驱动装置、集流管、连接管、喷嘴、信号反馈装置、安全泄放装置、控制盘、检漏装置、低泄高封阀、管路管件等部件构成；其采用全淹没灭火形式根据使用要求，可组成单元独立系统，组合分配系统实施对单区和多区的消防保护。

The pipe network fire extinguishing system generally consists of a group of fire extinguishing agent bottles, a group of driving gas bottles, a one-way valve, a selection valve, a pressure reducing device, a driving device, a collecting pipe, a connecting pipe, a nozzle, a signal feedback device, a safety release device, a control panel, a leak detection device, a low release high sealing valve, pipeline fittings, and other components; It adopts a fully submerged fire extinguishing form and can form a unit independent system according to usage requirements. The combined distribution system implements fire protection for single and multiple zones.
