There are several types of fire protection alarm valves used in fire protection systems. These valves play a crucial role in controlling the flow of water or fire-suppressing agents and activating alarm signals when triggered by fire detection devices. Here are some common types of fire protection alarm valves:
Butterfly Valve:
Butterfly valves are quarter-turn valves with a disc that rotates to control the flow of water or fire-suppressing agents. They are often used as alarm valves in deluge systems or preaction systems, where the valve remains closed until a fire detection device activates it.
Gate Valve:
Gate valves are widely used in fire protection systems. They have a sliding gate-like disc that lifts or lowers to control the flow of water. In alarm valve applications, gate valves are typically used in dry pipe systems or preaction systems, where the valve remains closed until a fire detection device triggers it.
Check Valve:
Check valves are designed to allow the flow of water or fire-suppressing agents in one direction while preventing backflow. In fire protection systems, check valves are often used as alarm check valves. They allow water to flow into the system when the pressure exceeds a certain threshold, triggering an alarm.
Globe Valve:
Globe valves have a globe-shaped body and a movable disk or plug that controls the flow of water or fire-suppressing agents. In fire protection systems, globe valves may be used as alarm check valves or control valves to regulate the water supply and pressure.
Pressure Reducing Valve:
Pressure reducing valves are used to regulate and maintain a specific pressure in a fire protection system. They are often employed in high-rise buildings or areas with varying water pressures. Pressure reducing valves can be used as alarm control valves to ensure consistent pressure for sprinkler systems.
Pressure Relief Valve:
Pressure relief valves are safety devices that automatically release excess pressure in a fire protection system. They help protect the system and components from damage due to excessive pressure. Pressure relief valves may be used in alarm valve applications to prevent over-pressurization of the system.
It’s important to note that the specific type of alarm valve used in a fire protection system depends on factors such as the system design, the type of fire detection and suppression system, and local codes and regulations.
