55130 Pressure Relief Valve Safety Relief Valve Device

A pressure relief valve is a constant pressure protection device, such as a safety device for power transformers, high voltage switches, On load switches, pressure vessels,Oil Immersed Transformers etc., used to protect oil tanks and containers from deformation or bursting. When an accident occurs inside oil immersed electrical equipment, the oil inside the tank is vaporized, producing a large amount of gas, causing a sharp increase in internal pressure inside the tank. If this pressure is not released in a timely manner, it will cause the fuel tank to deform or even burst. Installing a pressure relief valve means that when the fuel tank pressure rises to the opening pressure of the relief valve, the relief valve quickly opens within 2ms, causing the fuel tank pressure to quickly decrease. When the pressure drops to the closing pressure value of the pressure relief valve, the pressure relief valve reliably closes, maintaining a positive pressure inside the oil tank, effectively preventing external air, water vapor, and other impurities from entering the oil tank, avoiding the defect of the safety airway requiring power outage and replacement of components after operation. Compared to the safety airway, it has the advantages of reliable and accurate operation.
