The Quartz Tube Double Color Level Gauge is a secondary instrument that shows the liquid level position directly by using the optical principle. It can be widely used in the steam drum and storage of high and medium pressure boilers. The liquid level meter, in the coexistence of water cars, the water phase is green, the vapor phase is red, the water level boundary is very obvious for observation; When the water is full, the whole string is green, when the steam is full, the whole string is red, completely overcome the general liquid level meter can not be resolved when the water or steam is full, so as to cause serious accidents. At the same time, the table also has the advantages of simple structure, convenient maintenance, safety and reliability
Structure principle of quartz tube type two-color level gauge
Quartz tube two-color level gauge is composed of upper valve, lower valve, body, blowdown valve, balance tube and lampshade.
In addition to manual full opening and full closing of upper and lower valves, there are one insurance seat and one insurance ball inside the valve body. When the quartz tube is damaged accidentally, the insurance ball will automatically close the upper and lower channels of the table body under the impact of high pressure soda at high speed. Until the upper and lower valves are closed manually. The reset of the insurance ball is achieved by balancing the pressure and making the weight of the insurance ball. Therefore, there will be no false water level and other adverse phenomena. At the same time, this level gauge in addition to a special protective cover, the level gauge body itself is an excellent protective cover, so it is very safe and reliable.
