Description

TECHNICAL FIELD

[0001] The utility model relates to two -color water level gauge technical field especially relates to a device of prolonging two -color water level gauge light source board life. BACKGROUND

[0002] Two -color water level gauge is often used for gas -fired boiler drum water level monitoring, and the water in the drum enters the water level gauge body through the positive pressure side of the water level gauge, and then the water level is displayed through the light source plate composed of light emitting diodes by refraction principle. The body is sealed by several mica sheets to prevent leakage of steam.

[0003] In the prior art, the use temperature of the water level gauge body is too high, and the mica sheet for sealing has a service life of about 6 months. After exceeding the service life, high-temperature steam is prone to leakage. The light source plate and the water level gauge body are in the same light source cover. The leaked steam is all accumulated in the light source cover. If the steam is not isolated in time and accumulated in the light source cover for a long time, the high-temperature steam will directly damage the heat insulation glass and the light source plate composed of light emitting diodes. The light source plate cannot be monitored in time after being damaged. It is a big hidden danger for equipment and production safety. Therefore, the device should be reasonably improved according to the defects. CONTENT OF THE UTILITY MODEL
