全天候阻火呼吸閥性能及特點:Performance and characteristics
1. 安裝在固定頂罐上作通風裝置達到減少油品蒸發損耗及控制儲罐壓力和阻止外界火焰傳入；
The ventilation device installed in the fixed roof tank to reduce the evaporation loss of oil and control the tank pressure and prevent external flame spread.
2. 通風量大，泄漏量小，耐腐蝕等特點；
A large amount of ventilation, a small amount of leakage,corrosion resistance and other characteristics.
3. 通過靜電接地線使閥體和罐體保持等電位；
The electrostatic grounding wire to make the body and the tank to keep other potential.
4. 防凍性能強，適用于寒冷地區。
Antifreezing performance is strong, suitable for cold area.
