Product Description
Automatic wet sprinkler system with ZSFZ valve is the most common fixed automatic fire extinguishing equipment. The complex consists of key components: a wet alarm valve assembly, a delay valve, a hydraulic sound alarm, a pressure switch, a water flow indicator and closed sprinklers. The system is constantly in standby mode, the pipeline is completely filled with pressurized fire water, preparation by pumping gas is not required, the response time is minimal.
When a fire occurs in the protected area, the temperature rises to the sprinkler response threshold, the heat-sensitive glass bulb inside is destroyed by heat, the sealing elements fall off, the system automatically starts, pressure water is supplied through the pipes directly to the fire. At the same time, the hydraulic bell and pressure switch are triggered, issuing a sound and light alarm and transmitting a signal to the fire station, implementing a set of tasks: early warning, localization and fire extinguishing. The system is safe, stable and easy to maintain, suitable for any objects that allow water fire extinguishing. It is installed en masse in production workshops, warehouses, hotels, shopping centers, hospitals, cinemas, high-rise offices and underground parking lots and other standard areas with fire hazard.
