53300緊急壓力井蓋型泄壓裝置
Protectoseal 53300系列緊急壓井蓋通風口提供緊急救濟儲罐壓力以及油罐清洗，檢查和維修工作方便。它們被設計為安裝在坦克的沙井開口，并提供大量減輕蒸氣的一種手段，超出了正常經(jīng)營能力發(fā)泄'系列5.33萬沙井蓋不提供救濟的真空。真空救濟必須由操作孔（見Protectoseal型號830，型號8540H，型號6240，型號16240和型號18540）。
當一個法蘭坦克上正確安裝沙井開幕，系列號5.33萬井蓋通風提供了一個有效的汽體密封。在緊急火災情況下，完全打開通風，讓蒸氣逸出，并防止損壞水箱因壓力過大。封面必須手動重新定位后，排氣發(fā)生。

EMERGENCY PRESSURE
MANHOLE COVER VENT

Series No. 53300

Protectoseal Series No. 53300 Emergency Pressure Manhole Cover Vents provide emergency pressure relief for storage tanks as well as convenient access for tank cleaning, inspection and repair work. They are designed for installation on the manhole openings of tanks and provide a means of relieving large volumes of vapors, beyond the capacity of a normal operating vent, if an emergency fire involvement of the tank should occur. Series 53300 Manhole Covers do not provide vacuum relief. Vacuum relief must be supplied by operating vents (See Protectoseal Model No. 830, Model No. 8540H, Model No. 6240, Model No. 16240 and Model No. 18540).

When properly installed on a flanged tank manhole opening, the Series No. 53300 Manhole Cover Vent provides an effective vapor seal. Under emergency fire conditions, the vent opens fully to allow escape of vapors and prevent damage to the tank due to excessive pressure. The cover must be manually repositioned after venting has occurred.
