Introduction to pipe network type sevoflouropropane fire extinguishing series:


Sevofluoropropane gas automatic fire extinguishing system device is the most widely used type in the world at present, its clean and environmental protection, non-conductive, not destroy atmospheric ozone, under normal temperature pressure liquefaction, under normal temperature and pressure conditions can all volatilize. No residue after extinguishing. The principle of fire extinguishing is to interrupt the burning chain and put out the fire quickly.

Of seven fluorin propane fire extinguishing system main components of fire extinguishing agent storage bottles, containers, one-way valve, metal high-pressure pipe, extinguishing agent, signal feedback device, safety relief valve, selector valve, header pipe, drive, drive the group header pipe, solenoid valve, nozzle pipe fittings and other components, can be divided into unit, independent group distribution form, enforce the protection of single zone and the zone. The system has automatic control, electrical manual control, mechanical emergency manual control three ways.

Non - toxic and non - residual characteristics of deep - rooted, the application of technology is very mature.

Fire protection for:

Electrical and electronic equipment fire;

Combustible liquid and soluble solid fire;

Fixed surface fire;

Can cut off the gas source before extinguishing.

Widely applicable to the following enclosed places:

Precious treasures, data files, software and hardware facilities, communication rooms, computer rooms, etc.;

The use of water spraying system will cause water loss facilities;

Equipment and areas where it is difficult to remove residues after spraying fire extinguishing agents;

Areas where people often work, such as computer rooms, communication control centers, etc.

Functional features:

A set of pipe network fire extinguishing system can protect eight protection areas at the same time. The total project cost will be reduced to facilitate centralized monitoring and maintenance. The equipment needs bottle groups and is suitable for new projects. The design and installation are complicated and the construction period is long. The horizontal differential pressure type double-seal container valve is adopted to ensure high sealing and safety.
