Relief valve - Wikipedia
https://en.wikipedia.org/wiki/Relief_valveA relief valve or pressure relief valve (PRV) is a type of safety valve used to control or limit the pressurein a system; pressure might otherwise build up and create a process upset, instrument or equipment failure, or fire. The pressure is relieved by allowing the pressurized fluid to flow from an auxiliary passage out of the system. The relief valve is designed or set to open at a predetermined s…

https://www.swan-associates.com/documents/Eng_Handbook.pdf · PDF tệpthe pressure relief valve, therefore, is the process fluid. Once a condition occurs that causes the pressure in a system or vessel to increase to a dangerous level, the pressure relief valve may be the only device remaining to prevent a catastrophic failure. Since reliability is directly related to the complexity of the device, it is important that
