、 灭火装置 简介 1. Brief introduction of fire extinguishing device
HFC-227ea ）是一种化学方式灭火的洁净气体灭火剂。 Heptafluoropropane ( HFC-227ea ) is a clean gas extinguishing agent that extinguishes chemically. It is colorless, odorless, low-toxic, non-conductive, and does not pollute the protected object. , （ ODP 值为零）符合环保要求，是哈龙灭火剂在现阶段比较理想的替代物。 In particular, it has no destructive effect on the atmospheric ozone layer . ( ODP value is zero) meets environmental protection requirements. It is an ideal substitute for halon fire extinguishing agents at this stage. The fire extinguishing agent has high fire extinguishing efficiency, high speed and no secondary pollution. Cabinet-type heptafluoropropane fire extinguishing device is a prefabricated system, which is produced in series. It is a pipe-free, portable, portable, automatic fire-fighting fire-fighting equipment with flexible and convenient installation and beautiful appearance. Fire extinguishing agent has no loss of pipe network, high fire extinguishing efficiency, fast speed, and no pollution. In the event of a fire, spraying fire extinguishing agents directly into the protected area is convenient and quick.
灭火装置 不设储瓶间，储气瓶及整个系统均设置在保护区内，适用于计算机房、档案馆、贵重物品库、 电讯中心等较小空间的保护区，几台 柜式七氟丙烷气体灭火 装置联用也可以保护较大空间的保护区。 This fire extinguishing device does not have a bottle storage room. The gas cylinders and the entire system are set in a protected area. It is suitable for small areas such as computer rooms, archives, valuables storage, telecommunications centers, etc., and several cabinets of heptafluoropropane gas. The combination of fire extinguishing devices can also protect large areas of protection. This device can be connected to the fire control center, or it can be equipped with an automatic fire extinguishing controller separately, which is a self-contained system, giving users convenient and flexible choices. For existing buildings that need to be equipped with a fire extinguishing system, a cabinet-type heptafluoropropane fire extinguishing device is more appropriate.
、灭火剂特点 2. Characteristics of fire extinguishing agent
