Fire Extinguishing System of Water Spray

Fire Extinguishing System of Water Spray

Description：

The fire extinguishing system of water spray is a wet automatic sprinkler system. It is suitable for engineering ships, ro-ro passenger ships, tourist ships and so on in living cabins, corridors, public places of casinos with more than 30 Persons.

The system pipe network is full of pressurized fresh water, and it is in a standby working state for a long time. It is suitable for use in an ambient temperature of 4 degree~70 degree (the sprinkler can only be installed vertically and vertically). When a fire occurs somewhere in the protection area, the ambient temperature rises to 68 degree (When the temperature sensitive element of the nozzle in the corresponding area melts, the nozzle starts to spray water.

Working Principle：

Under the action of the pressure difference, the wet alarm valve is automatically opened (after a delay of about 30 seconds by the delay tank, the hydraulic alarm bell will alarm to indicate the wet alarm). Valve action) and give a zone alarm and a comprehensive alarm signal, the sprinkler head sprays water directly to the fire occurrence area; the water source in the initial stage of fire extinguishing comes from the pressure water tank in the pressure maintaining system, when the pressure water tank is at a low level (when the liquid level is high) Stop), the make-up pump of the pressure maintaining system starts to take water from the fresh water tank. When the pressure water tank reaches the dry water level, the spray pump starts and provides the spray pump signal to the fire extinguishing control box to achieve the purpose of alarming.
