Description

technical field [0001] The invention relates to a thermal parameter measurement component, in particular to an integrated high-temperature nozzle structure integrating temperature and pressure parameter measurement, and belongs to the technical field of thermal parameter measurement equipment. Background technique [0002] In the measurement of thermal parameters at high temperature and high pressure, such as in nuclear energy hydrogen production, most of the key equipment for energy transfer and conversion operate in a high temperature and high pressure environment, such as the hydrogen production process of high temperature gas-cooled reactor coupled with iodine-sulfur cycle system , the key equipment in the system such as high temperature heat exchanger, sulfuric acid decomposer, etc., the operating temperature of the helium side is as high as 750-1000 ℃, and the pressure is 3-7MPa. The nozzles of these equipment in the system loop need to be connected through flanges , s...

AI Technical Summary

Problems solved by technology

In order to withstand such a high temperature and pressure, the existing design schemes are usually made of expensive superalloy materials, which have the following problems: first, the superalloy materials are expensive and the cost is high; Measuring instruments such as temperature cannot be directly placed in the pipeline, and it is difficult to measure the thermal parameters of the fluid in the pipeline. For example, it is necessary to set up a pressure pipe and a cooling system to realize the measurement of the pressure parameter; the third is that the nozzle connecting flange is in a high temperature environment , there are problems such as sealing difficulties
