The boiler pressure relief valve is a safety valve designed to relieved an excessive build up of pressure inside the boiler. The is a pressure vessel designed to handle a safe amount of pressure. If the pressure were to build up beyond the safety limitations as set forth by the design specifications the boiler system needs a safe way to vent the pressure to prevent an explosion. Furthermore, the boiler relief valve is this safe way to vent excessive dangerous pressures inside the boiler.
Boiler Pressure Relief Valve
In the old days some boilers did not have any pressure relief valves installed on the boiler. It was not uncommon for the system to build up pressure and an explosion occur. Typically, this would send the boiler through the roof of the house. Insurance companies got tired of paying the cost associated with these explosions. Therefore they decided to implement safety requirements as recommended by industry professionals and engineers. Professionals involved in boiler safety issues. As these changes were made some of these requirements were added to the mechanical and boiler codes. Codes for various states and municipalities.
Boiler Pressure Relief Valve | Code and Conclusion
Therefore, it is now in the mechanical code that a boiler be required to have a safety pressure relief valve. A relief valve to prevent too much pressure from building up in the pressure vessel whether it is steam or hot water. Lastly, make sure your boiler pressure relief valve is in proper order.
