External storage pressure hfc-227ea fire extinguishing equipment

Product description

The external pressure storage (backup pressure) HFC-propane fire extinguishing system consists of a fire extinguishing agent bottle group, a power gas bottle group, a high pressure metal hose, a check valve (fire extinguishing agent pipeline), a collecting pipe, and a safety discharge assembly It consists of setting, selecting valve, signal feedback device, fire extinguishing agent conveying pipeline, nozzle, driving gas bottle group, electromagnetic driving device, driving gas pipeline, check valve (driving gas pipeline), etc. The transmission distance of the external storage pressure system is generally not more than 250 meters. The gas extinguishing agent storage bottle of the SEvofluoropropane fire extinguishing system of the pipe network is usually placed in the special cylinder room and connected through the pipe network. When the fire occurs, the fire extinguishing agent is transported from the cylinder room to the protection area to be put out by spraying through the sprinkler head. It is the first choice for multi-zone protection of large buildings and can protect up to eight zones simultaneously.

How  to  Put out a fire

When the fire extinguishing system is in the automatic control state, when there is a fire in the protection area, the fire detector sends out a fire signal, the alarm controller immediately sends out an audible and optical alarm signal, the gas fire extinguishing control device receives two independent fire alarm signals, issues linkage instructions, closes the linkage equipment, and issues fire extinguishing instructions after a 30-second delay. Open the electromagnetic valve corresponding to the protection area to start the gas, and the starting gas opens the corresponding selection valve and the container valve of the power bottle group through the starting pipeline. The power bottle drives the gas into the fire extinguishing agent group through the pressure reducing device, and at the same time opens the capacitance valve of the fire extinguishing agent group, and sends the fire extinguishing agent to the pipe network for extinguishing the fire.
