[0002] The high-level tank can also be called the expansion tank. In the liquid phase thermal oil furnace heating system, the expansion tank is indispensable. The high-level tank is usually set at the highest point of the system to accommodate the thermal expansion of the heat transfer liquid.

[0003] However, in an open-type operating system, the oil is in contact with the air for a long time. In particular, when using heat transfer oil with light components and low initial distillation point and 2% point, a large amount of light components enter the high-level tank at high temperature, causing the heat transfer oil in the high-level tank to overheat and come into contact with the air, which leads to rapid oxidation and deterioration of the heat transfer oil. According to the analysis of actual user usage, the crux of this problem is that the oxygen in the air participates in the chemical reaction.

[0004] Therefore, we provide a two-stage two-level liquid sealing device for a high-level tank to solve the problem of the heat transfer oil overheating and contact with the air, which leads to rapid oxidation and deterioration of the heat transfer oil. Utility Model Content
