Pressure relief valve

Pressure relief valve

YSF9-55/130KJTHB, YSF9-55/80KJTHB

80mm and 130mm pressure relief valves are mainly suitable for pressure relief of large oil-immersed power transformer, power capacitor, reactor and other equipment when oil tank is overpressure.

When the internal pressure of oil-immersed power transformer tank rises sharply due to accident, if the pressure is not released in time, the tank will be deformed or even burst. Pressure relief valve can be quickly opened when the tank pressure rises to its opening pressure value, so that the pressure in the tank can be quickly reduced. When the pressure drops to the closing pressure value of the pressure relief valve, the pressure relief valve can be closed reliably, which can keep the positive pressure in the tank forever and effectively prevent the external air, moisture and other impurities from entering the tank. The pressure relief valve with directional injection device (hereinafter referred to as directional injection pressure relief valve) can directionally eject transformer oil released, and guide it into the oil catchment pool through the oil guide pipe to prevent oil splash and meet the requirements of fire prevention and environmental protection.

80mm and 130mm pressure relief valves, besides the conventional electrical alarm signal, can also add the design of computer-based electrical alarm signal function, which can realize the output of two electrical signals, and each of them can be independently drawn out. Users can select products according to their needs.
