Pipe network heptafluoropropane fire extinguishing system

Abstract: The fire protection system is an indispensable part of the data center equipment room. Due to the precision and importance of the equipment in the fire prevention of the equipment room, it is determined that only the gas fire extinguishing system can be used. In the gas fire extinguishing system, heptafluoropropane is used. The most extensive and greenest kind. The heptafluoropropane fire extinguishing system is divided into a pipe network and a pipeless network.

The fire protection system is an integral part of the data center equipment room. Because of the precision and importance of the equipment in the fire protection of the equipment room, it is determined that only the gas fire extinguishing system can be used. In the gas fire suppression system, heptafluoropropane is the most widely used. It is also the most green and environmentally friendly. The heptafluoropropane fire extinguishing system is divided into a pipe network and a pipeless network.

Pipe network heptafluoropropane fire extinguishing system

The body fire extinguishing agent storage bottle of the pipe network heptafluoropropane fire extinguishing system is usually placed in a special steel cylinder room and connected through a pipe network. When a fire occurs, the fire extinguishing agent is transported from the cylinder room to the protection area where the fire is needed and sprayed through the nozzle. Put out the fire.

System composition

Heptafluoropropane gas fire extinguishing system includes: fire extinguishing bottle group, high pressure hose, fire extinguishing agent check valve, starting bottle group, safety pressure relief valve, selection valve, pressure signal device, nozzle, high pressure pipeline, high pressure pipe fittings and other components.

1, fire extinguishing bottle group

Each fire extinguishing bottle group contains fire extinguishing agent storage bottles, flat control valves, safety valves, manual valves, pressure gauges, and heptafluoropropane fire extinguishing agents. Storage bottles can be divided into different models according to the size of the volume.

2, high pressure hose

The high pressure hose is a device that connects the fire extinguisher bottle group and the extinguishing agent check valve.

3, fire extinguishing agent check valve

Extinguishing agent check valve Installed between the high pressure hose and the manifold to prevent gas backflow.

4, start the bottle group

The starter bottle group is filled with nitrogen gas. When a fire occurs, the starter bottle group initiates the gas opening selection valve and the bottle head control valve to release the fire extinguishing agent when receiving the instruction.

The starter bottle set includes a gas cylinder, a bottle head control valve, an electromagnetic starter, a safety valve, a manual valve, a pressure gauge, and a start gas.

5, safety relief valve

Safety relief valves are used to prevent system overpressure.

6, select valve

When a pipe network heptafluoropropane fire extinguishing system protects multiple zones, a selection valve is used to control the extinguishing agent into the corresponding protection zone.

According to the size of the calculated pipe diameter, select the appropriate valve diameter selection valve.

7, signal pressure

The pressure signaler feeds back the extinguishing agent spray signal.

8, nozzle PLPT

Used to spray extinguishing agents.

9, high pressure pipeline

High pressure pipelines are used to deliver fire extinguishing agents.

10, high pressure pipe fittings

High-pressure pipe fittings are used to connect high-pressure pipes.

Application site

A pipe network heptafluoropropane gas fire extinguishing system is applicable to the fire protection of key parts such as: computer rooms, libraries, archives, valuable goods stores, power stations (transformer rooms), telecommunications centers, and clean workshops.

Pipeless (Cabinet) Heptafluoropropane Fire Extinguishing System

The gas extinguishing agent storage bottle is packaged into a fire extinguisher, which has a beautiful appearance and is usually placed in a protective area to be protected. In the event of a fire, the fire extinguishing is directly performed in the protective area without going through many pipelines.

introduction

No pipe network (cabinet) heptafluoropropane gas fire extinguishing system is a modern portable fire-fighting automatic fire detection equipment for automatic detection of fire, automatic alarm, and automatic fire extinguishing. Its fire extinguishing efficiency is high, the fire extinguishing speed is fast, the toxicity is low, and the equipment is not defaced. The device performance is excellent, and its control part can be linked with the fire control center.

Cabinet type heptafluoropropane fire extinguishing device

Application site

The cabinet type heptafluoropropane gas fire extinguishing system is suitable for the fire protection of key parts such as computer rooms, libraries, archives, valuable goods stores, power stations (transformer rooms), telecommunications centers, and clean workshops.

System composition

No pipe network (cabinet) heptafluoropropane gas fire extinguishing systems include storage bottles, starting devices, safety relief valves, pressure gauges, cabinets, pressure annunciators, injection short tubes, nozzles, and heptafluoropropane fire extinguishing agents.

Propylene and Hexafluoropropane - with or without pipe network

1. A pipe network system is sprayed through the pipe network, and the nozzles are evenly distributed, so the spraying is even and the fire extinguishing effect is good. No pipe network is generally sprayed directly by the tank nozzle and the spraying is not uniform enough;

2. There are pipe networks that need to set up separate cylinder rooms and set up pipe networks. No pipe network is not needed. If only one area is protected, the cost of the pipe network system is high from an economic point of view.

3, if multiple areas, a pipe network system can use the same system to protect multiple protection areas. Fires in different protection areas and targeted discharges are required. Without pipe network, separate cylinders and extinguishing agents are required for each protection zone. At this time, the price without pipe network is relatively high.

4, there are pipe network system cylinders in the cylinder. Because of the distance, so the required high pressure, usually 4.2MPa. Some are 5.6MPa.

5, no pipe network system in the protective zone. Because in the protected area, so the pressure can not be too high, so generally choose 2.5MPa.
