Supervisory Switch Alarm Valve For Dry Pipe Sprinkler System

SANJING FIRE supervisory switch alarm valve is a type of valve used in a dry pipe sprinkler system to monitor the system and detect any changes or abnormalities. The valve is typically installed at the system's main control valve and is designed to detect any loss of air pressure in the system.

The supervisory switch alarm valve consists of a valve body, a clapper assembly, and a supervisory switch. The clapper assembly is designed to prevent water from entering the dry pipe until the system is activated. The supervisory switch is connected to a monitoring system that can alert personnel to any changes or abnormalities in the system.

When the dry pipe sprinkler system is activated, the air pressure in the system drops, causing the clapper assembly to open and allow water to flow into the piping. At the same time, the supervisory switch detects the drop in air pressure and sends a signal to the monitoring system, alerting personnel to the activation of the system.

Regular maintenance and inspection of the supervisory switch alarm valve is important to ensure proper function and prevent leaks or other failures that could compromise the safety of the system. The valve should be checked regularly to ensure that it is in good working order, and any problems or malfunctions should be addressed promptly.
