Protectoseal 51600系列鉸鏈緊急壓力井蓋泄壓裝置提供存儲暴露給外部消防坦克緊急泄壓。他們的目的是開放，并提供超出了正常呼吸能力泄壓口。該系列號51600的設計允許設置較高的泄壓比在我們的系列號5.33萬人孔蓋及緊急通風壓力可用。該系列號51600套真空排氣不提供救濟。
真空救濟必須由經營發(fā)泄（見Protectoseal系列第830號8540H系列，6240系列號，系列號16240或系列號18540）
這些通風口安裝在水箱人孔法蘭。當正確安裝，該設備提供了一個有效的汽體密封。在緊急火災情況下，蓋可打開它的鉸鏈支點，并提供所需的救濟，防止損壞坦克，由于內部壓力過大。當油箱壓力降低，覆蓋自動recloses。鉸接設計允許使用的杠桿主要抗衡使壓力設定值比其他更高的自重可裝載同樣大小的通風口可能得以實現(xiàn)。全部無阻流量和自動排氣壓力減小重合為坦克提供高效，可靠的緊急排氣能力，同時盡量減少不必要的水汽量排放到大氣中。該設計還可以通過對坦克的檢查和維修方便沙井開放。

HINGED EMERGENCY PRESSURE
MANHOLE COVER VENT
Series No. 51600
Protectoseal Series No. 51600 Hinged Emergency Pressure Manhole Cover Vents provide emergency pressure relief for storage tanks that are exposed to an external fire. They are designed to open and provide pressure relief beyond the capacity of the normal breather vents. The Series No. 51600 design allows for higher pressure relief settings than are available on our Series No. 53300 Manhole & Emergency Pressure Cover Vent. The Series No. 51600 Cover Vent does not provide vacuum relief. Vacuum relief must be supplied by an operating vent (See Protectoseal Series No. 830, Series No. 8540H, Series No. 6240, Series No. 16240 or Series No. 18540).
These vents are mounted on the tank manhole flange. When properly installed, the device provides an effective vapor seal. Under emergency fire conditions, the cover can pivot open on its hinge and provide required relief, preventing damage to the tank due to excessive internal pressure. When tank pressure is reduced, the cover automatically recloses. The hinged design allows the use of a lever principal counterweight so that the pressure settings higher than those available on other dead weight loaded vents of similar size may be achieved. Full open flow capacity and automatic reclosing of vent as tank pressure decreases provide efficient and dependable emergency venting capability while minimizing amount of vapor unnecessarily vented to the atmosphere. The design also allows convenient access through the manhole opening for tank inspection and maintenance.
