The invention relates to an active cooling type vacuum environment high temperature liquid metal flowmeter, comprising a magnetic steel assembly, a liquid metal pipeline, a cooling assembly and a conductive assembly; the liquid metal pipeline passes through the magnetic steel assembly so that the flow in the liquid metal pipeline cuts the The magnetic induction lines produced by the magnetic steel assembly are used to generate the induced electrical signal; the conductive assembly is used to transmit the induced electrical signal; the cooling copper block and the cooling copper pipe included in the cooling assembly; the cooling copper block is set in the liquid state Between the metal pipe and the magnetic steel assembly, the heat transferred to the magnetic steel is reduced; a cooling copper pipe with a cooling fluid inside is provided in the middle of the cooling copper block to cool the cooling copper block through the cooling fluid. The beneficial effects of the present invention are as follows: the permanent magnet flowmeter provided by the present invention can be used in vacuum or atmospheric environment, and the flow measurement of the liquid metal in the pipeline with the temperature of the working medium ranging from the melting point to 1000°C, especially suitable for the temperature range of 600°C to 1000°C in the vacuum environment Flow measurement of liquid alkali metals in pipelines in the ℃ range.
Description
technical field [0001] The invention belongs to the field of nuclear industry, in particular to an active cooling type vacuum environment high temperature liquid metal flowmeter. Background technique [0002] With the development of science and technology, it is sometimes necessary to measure the flow rate of the pipeline with a high temperature liquid alkali metal working fluid of 1000°C in a vacuum environment. [0003] In the vacuum environment, the thermal radiation generated by the high-temperature pipeline makes the temperature of the surrounding objects very high. For the measurement, for the permanent magnet installed at a short distance, the high temperature will make the magnetic field decrease or even disappear, while the long-distance installation will Causes a dramatic increase in the volume and weight of the permanent magnet or a decrease in the performance of the flowmeter. [0004] In view of this, the present invention is proposed. SUMMARY OF THE INVENTIO...
