Description
technical field [0001] The application belongs to the technical field of power plant equipment, and in particular relates to a pressure limiting device and a steam-water system. Background technique [0002] In the steam-water system of the power plant, the steam-water sampling decompression device is used to decompress the steam-water sampling into the online chemical instrument. The water pressure requirement is high. If the water pressure is too high, the online chemical meter will be damaged. If the pressure is too low, the online chemical meter will measure inaccurately. Therefore, only the appropriate water sample pressure can ensure that the online chemical meter can accurately measure the water quality in real time. data. [0003] In practical application, a pressure limiting device is set between the soda sampling pressure limiting device and the on-line chemical instrument to limit the pressure of the decompressed water sample, thereby providing a stable working e...
