51600铰链紧急压力井盖泄压装置
Protectoseal 51600系列铰链紧急压力井盖泄压装置提供存储暴露给外部消防坦克紧急泄压。他们的目的是开放，并提供超出了正常呼吸能力泄压口。该系列号51600的设计允许设置较高的泄压比在我们的系列号5.33万人孔盖及紧急通风压力可用。该系列号51600套真空排气不提供救济。
真空救济必须由经营发泄（见Protectoseal系列第830号8540H系列，6240系列号，系列号16240或系列号18540）

这些通风口安装在水箱人孔法兰。当正确安装，该设备提供了一个有效的汽体密封。在紧急火灾情况下，盖可打开它的铰链支点，并提供所需的救济，防止损坏坦克，由于内部压力过大。当油箱压力降低，覆盖自动recloses。铰接设计允许使用的杠杆主要抗衡使压力设定值比其他更高的自重可装载同样大小的通风口可能得以实现。全部无阻流量和自动排气压力减小重合为坦克提供高效，可靠的紧急排气能力，同时尽量减少不必要的水汽量排放到大气中。该设计还可以通过对坦克的检查和维修方便沙井开放。

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.
