The boiler water level gauge needs to be cleaned regularly to avoid affecting its use. Generally, the flushing method is adopted. Before cleaning, first close the secondary valve of the water level gauge, then open the drain valve of the water level gauge, and then close the drain valve after the water is drained. There are two methods for flushing the water level gauge:

1. Water flushing

First, close the steam side primary and secondary valves and water side secondary valves of the water level gauge to isolate the water level gauge. Then open the drain valve of the water level gauge, close the drain valve after the water is drained, and then start the flushing of the water level gauge. The flushing water level gauge controls the pressure of the flushing water by opening and closing the secondary valve at the water side. Slowly and slightly open the secondary valve at the water side of the water level gauge to make the water flow through the connecting pipe between the secondary valve at the water side, the secondary valve at the steam side, and the water level gauge in order to make the water level gauge full of water, then close the secondary valve at the water side, open the blowdown valve, and take away the dirt depending on the pressure in the water level gauge and the weight of the water. After several times of washing, check. If the water level gauge is clear, stop washing.

2. Steam flushing

First, close the primary and secondary valves of the water level gauge completely, then slightly open the blowdown valve, open the primary valve at the steam side to fully open, and then slowly open the secondary valve at the steam side for 1/5 turn. Use high-pressure steam to wash the scaling mica, and adjust the flow of high-pressure steam by controlling the opening of the secondary valve at the steam side (the opening should not be too large, otherwise the channel will be blocked by the fuse). The flushing time is 3-5 minutes. If the water level gauge is clear, the flushing can be stopped. After flushing, close the secondary valve, blowdown valve and primary valve.
