Abstract

The disclosure belongs to the technical field of instrumentation for liquid metal, and in particular relates to a multi-purpose probe applied to liquid level detection and temperature measurement of high-temperature liquid metal. The multi-purpose probe comprises a structural piece, a transition connecting piece, an insulating piece, and a sealing piece; wherein the insulating piece is made of high-temperature-resistant ceramic materials; the structural piece is made of stainless steel materials; the structural piece comprises a threaded male connector, an upper compressing piece, a threaded female connector, a lower connecting tube, and a center probe; and the insulating piece comprises a ceramic tube. The multi-purpose probe has the beneficial effects that: a high-temperature liquid metal probe adopts a ceramic tube which is both a structural piece and an insulating piece, and the sealing piece adopts a metal gasket; when stainless steel materials are used for other structural piecesand connecting pieces, the maximum use temperature can reach 650 DEG C; if a nickel-based alloy or a refractory metal material is used as substitutes for manufacturing the probe and a threaded connection piece, the temperature resistance can be further improved to 1000 DEG C.

Description

technical field [0001] The disclosure belongs to the technical field of detection instruments for liquid metal, and in particular relates to a multi-purpose probe applied to liquid level detection and temperature measurement of high-temperature liquid metal. Background technique [0002] In liquid metal devices, temperature and liquid level are important parameters related to operation and safety. Due to the high operating temperature of liquid metals, especially liquid metal working fluids such as sodium, sodium-potassium alloys, lithium, and lead-bismuth alloys, which also have active chemical properties, generally cannot be in direct contact with air, and require high airtightness of the equipment, so Compared with common working fluids such as water, the temperature and liquid level measurement in liquid metal equipment is more difficult. [0003] The measurement of liquid metal temperature generally adopts the method of thermocouple trap, that is, a blind tube is used ...
