In a wet sprinkler system, there are several check valves and other components. It is also important that in any sprinkler system which is used specifically for fire suppression to have alarm check valves all over. Contradictory to some common myths and beliefs, alarm check valves are not intended for preventing backflow. They may certainly help for preventing water in the sprinkler to not get back flowed in the reservoir or source which leads to potential contamination of the water supply. But the main purpose is to keep back the water pressure in the sprinkler system until such time as it is required.
In one of the basic two ways, an alarm check valve can be activated. Either manually when a person is activating a water gong or electronically. Once the alarm check valve is activated, they will allow water to flow through the system which engages the sprinkler system as and where required in order to suppress a potential fire.
Basics of an Alarm Check Valve
At the basic core, a valve is going to help control water throughout a web standpipe system, this can be underground but the majority of alarm check valves are used above ground mainly in buildings and high rises. As the nature of water being corrosive, when it sits idle for any length of time it can increase the corrosion of the pipes. The alarm check valves also help in minimizing this corrosion level by limiting the pressure within the pipes until such time as it is required. Once it is activated, the alarm check valves will open and allow the full pressure of water to fill the system. Another purpose of these valves is tremendously beneficial in high rise buildings and other structures which would contain a tremendous length of piping throughout its wet pipe system. This will automatically control the flow of water via the system itself. If work is required to be done on any point in the system, the technician will require to close the valves either manually or drain out the entire system of water to the point where work requires to be done. This would not be necessary using an electronically controlled system with check valves.
Risks that lie if you ignore Alarm Check Valves
If you do not use alarm check valves in a sprinkler system, then there are two scenarios that can happen. Either someone will have to open the valves manually for allowing water into the sprinkler system or the entire system will be under full pressure constantly that can lead to issues in the event of surges or corrosion. Anyone who is designing, upgrading, or building a sprinkler system will always consider using alarm check valves whether or not required by the law. If you choose, higher quality of valves, your security is bound to evolve and will help to protect the investment in those buildings and those individuals who use them.
