Secondary steam outlet pressure measuring system of final concentrator

The utility model relates to the technical field of pressure detection systems, in particular to a pressure measuring system for a secondary steam outlet of a final concentrator, which is characterized in that a steam blocking drainage tank is arranged on one side of a pre-concentrator, and a secondary steam outlet on the final concentrator is communicated with a secondary steam inlet on one side of the pre-concentrator through a steam pipeline; a vertical water seal pipeline is arranged on the steam pipeline close to the secondary steam inlet, the top end of the water seal pipeline is communicated with the steam pipeline, a pressure transmitter is arranged on one side of the bottom of the water seal pipeline, a secondary steam discharge port is formed in one side of the upper portion of the preconcentrator, secondary steam is pumped out through the secondary steam discharge port to be condensed, and the secondary steam discharge port is communicated with the steam pipeline. A control valve is arranged on the
