The wet automatic sprinkler system composed of water flow indicator, pressure switch, sprinkler head, etc. is a fixed system with extremely wide application. The pipe network of the system is filled with clean water under a certain pressure all year round, and it is in a standby working state for a long time; when a fire occurs somewhere in the protected area, the ambient temperature in the area rises; the organic solution in the thermally sensitive element (glass ball) of the sprinkler Thermal expansion will generate a large internal pressure until the glass bulb shell is broken, so that the nozzle sprinkler is turned on, and the entire system is automatically activated to send out sound and light alarm signals to achieve the purpose of fire alarm, fire control, and fire suppression.
