拱顶轻油罐罐下采样装置,经有关单位数年的实践证明,具有安全、省力、省时、准确及操作方便等优点;其采样化验结果与罐顶人工取样完全一致。装置结构见图1。 随着内浮顶油罐的广泛使用和发展,期望实现罐下采样。图1的结构难以适用,因为内浮顶罐比拱顶罐罐内多了一个内浮盘,并有“星罗棋布”的浮盘支撑柱,这些均使浮标1及支撑管3无法工作。我们新设计时一种适用于内浮顶油罐的罐下采样装置(又称柔性采样装置),罐内部分管件采用
Vault tank sampling device under the tank, the unit proved a few years after the practice, with safety, labor-saving, time-saving, accurate and easy to operate and other advantages; the sampling results of the experiment and the tank roof exactly the same artificial sampling. Device structure shown in Figure 1. With the widespread use and development of internal roof tanks, it is desirable to achieve sub-tank sampling. The structure of FIG. 1 is difficult to apply because the inner floating top tank has one more inner floating tray than the dome tank and a “dotted” floating support column, which makes the buoy 1 and the support tube 3 inoperable. Our new design for a floating tank under the tank sampling device (also known as flexible sampling device), the tank part of the use of pipe fittings
