Safety requirements for water level gauge
each boiler shall be equipped with at least two independent water level gauges. The evaporation capacity is less than or equal to 0.5. Under the current rapid development trend of electric vehicles, t/h boilers can be equipped with a water level gauge
the water level gauge should be installed in a place convenient for observation and washing, and there should be sufficient lighting; The water connection pipe and steam connection pipe shall be horizontally arranged to prevent the formation of false water level; The inner diameter of the connecting pipe shall not be less than 18mm, and the connecting pipe shall be as short as possible. If the length exceeds 500mm or there is bending, the inner diameter shall be appropriately enlarged; Valves shall be installed on steam and water connecting pipes and kept fully open during operation; The water level gauge shall have a drain cock and a drain pipe connected to a safe place. The inner diameter of the steam cock, water cock, drain cock and the inner diameter of the glass tube of the water level gauge shall not be less than 8mm
the water level gauge shall have obvious signs indicating the highest and lowest safe water levels. The lowest visible edge of the glass tube (plate) of the water level gauge shall be at least 50mm higher than the highest fire boundary, 25mm lower than the median of the lowest safe water, and the highest visible edge shall be 25mm higher than the highest safe water level
in order to prevent the water level gauge from damaging and hurting people, the glass tube water level gauge should be equipped with protective devices, but it should not prevent the observation of the real water level
boiler is an innovative measure. During the operation of the boiler, the water level gauge should be monitored at any time and washed regularly
