Protectoseal系列编号830,压力/真空排气保护与阻火器,是为了防止昂贵的蒸发损失,油箱破裂,由于过度的压力,由于真空崩溃。阻火器可以防止火灾和火源的外部油箱爆炸引起的。在托盘发泄住房尽量减少坦克“呼吸”空气和蒸汽的损失。他们打开和关闭刚够维持安全的工作压力,避免损坏水箱。阻火器的安装外,只接触到蒸气中的宣泄
D组适用于蒸汽,如汽油和甲烷,作为全国电气规程(NEC 500条),一般相当于国际电工委员会(IEC)集团国际投资协定引用。

PRESSURE / VACUUM CONSERVATION VENT WITH FLAME ARRESTER
Series No. 830
Protectoseal Series No. 830, Pressure / Vacuum Conservation Vent with Flame Arrester, is designed to prevent costly evaporation losses, tank rupture due to over-pressure, and collapse due to vacuum. The flame arrester protects tank against fire and explosion caused by exterior sources of ignition. Pallets in the vent housing minimize air and vapor loss as the tank "breathes". They open and close just enough to maintain safe working pressures and avoid damage to the tank. The flame arrester is mounted externally and is only exposed to vapors when venting.
Suitable for Group D Vapors, such as gasoline and methane, as referenced in the National Electric Code (NEC Article 500), generally equivalent to International Electrotechnical Commission (IEC) Group IIA.
