[0010] Compared with the prior art, the beneficial effects of the utility model are:

[0011] In the utility model, when the high-level tank of the expansion tank reaches a critical value, the heat transfer oil flows into the alarm oil storage tank through the connecting pipe, the detection sensor detects the heat transfer oil and issues a warning, thereby realizing the oil cross-prevention warning function of more than two heating systems. After the fault is eliminated, the oil drain valve is opened to drain the heat transfer oil in the alarm oil storage tank, so that the variable in the alarm oil storage tank disappears, and the alarm is released. The heat transfer oil in the alarm oil storage tank enters the oil storage tank through the oil drain pipe. After the fault is eliminated, the state can be quickly reset, and at the same time, the heating system can continue to be effectively warned of oil cross-prevention.

After troubleshooting, open the oil drain valve 18 to drain the heat transfer oil in the alarm oil storage tank 15, so that the variable in the alarm oil storage tank 15 disappears, and then the alarm is lifted. The heat transfer oil in the alarm oil storage tank 15 enters the oil storage tank 11 through the oil drain pipe 17. When the fault is eliminated, the state can be quickly reset, and at the same time, the heating system can continue to be effectively warned of oil cross-talk.
