Liquid level measuring device for double-chamber balance container

Abstract

The invention provides a liquid level measuring device for a double-chamber balance container. The device comprises a double-chamber balance container barrel body, an upper sealing head, a lower sealing head, an upper connecting pipe, a lower connecting pipe, a T-shaped communicating vessel, a positive pressure pipe, a blow-off pipe, a condensing coil, a negative pressure pipe, a boiler, a steam pocket steam phase guide pipe, a blow-off treatment antifouling discharge pipe structure, an automatic control release pipe structure capable of preventing steam pressure from being too high and an adjustable support mounting frame structure. According to the arrangement of the double-chamber balance container barrel, condensed water flowing back from the condensing coil can be collected and discharged into a descending pipe of a boiler, the whole container is heated and subjected to heat storage in the flowing process, it is guaranteed that the temperature in the container and the temperaturein a steam pocket are consistent, and then the accuracy of a measurement result is guaranteed. The arrangement of the T-shaped communicating vessel is beneficial to ensuring that the water level height of the communicating vessel changes along with the water level of the steam drum, so that the pressure of the positive pressure side changes along with the pressure change of the boiler steam drum,thereby ensuring the measurement accuracy, reducing the liquid level measurement error and improving the detection efficiency.

Description

technical field [0001] The invention belongs to the technical field of boiler steam drum liquid level measurement, and in particular relates to a liquid level measurement device for a double-chamber balance container. Background technique [0002] The double-chamber balance vessel is a liquid level measuring device with a certain self-compensation ability. Its main structure has a container cylinder. The upper part of the same side of the container cylinder is connected with a steam connection pipeline, and the lower part is connected with a liquid connection pipeline. The steam connection pipeline is equipped with a steam inlet valve, and the liquid connection pipeline is equipped with a water inlet valve. The container cylinder The bottom of the tank is connected with a sewage pipeline, and a sewage valve is installed on the sewage pipeline. A reference cup is located in the container cylinder below the steam outlet end of the steam connection pipeline. The pressure pipel...
