The effect is to reduce the evaporation loss of oil products and protect the tank from overloading. 是(活瓣式)呼吸阀的安全备用设备,它的吸气和呼气的动作压力略高于(活瓣式)呼吸阀,在呼吸阀一旦失灵或在冬季其活瓣冻结时,液压安全阀的液封即被破坏从而保护油罐免遭破坏。 The hydraulic safety valve is a safety backup device of the (valve type) breathing valve. Its actuation pressure for inhalation and exhalation is slightly higher than that of the (valve type) breathing valve. Once the breathing valve fails or its flap freezes in winter At this time, the liquid seal of the hydraulic safety valve is broken to protect the oil tank from being damaged. ~ Hydraulic safety valve is a safety backup device for (valve type) breathing valve.
