SANJING wet pipe alarm valve is a component of a fire sprinkler system that is designed to regulate water flow to the sprinkler heads and sound an alarm when water is flowing through the system.
In a wet pipe fire sprinkler system, water is constantly present in the pipes, and when a fire breaks out, the heat from the flames triggers a sprinkler head, causing it to open and release water onto the fire. The wet pipe alarm valve is located near the connection point between the water supply and the sprinkler system, and it is responsible for controlling the flow of water to the sprinkler heads.
When water flows through the valve, it activates a water flow alarm that sounds an audible alert to notify building occupants of the fire. This allows them to evacuate the building and call the fire department. The wet pipe alarm valve also has a tamper switch that sends a signal to the fire alarm system if someone attempts to close the valve or disable the water flow alarm.
