Abstract

The invention relates to a novel molten salt temperature switch and a preparation method thereof, which belong to the technical field of temperature switches. The novel molten salt temperature switch comprises a stainless steel screw cap (1), conductive sheets (2), an insulation pipe (3), molten salt (4) and conductive wires (5), wherein the molten salt (4) is arranged in the insulation pipe (3),both ends of the insulation pipe (3) are respectively connected with the conductive sheets (2) through screw threads, the outer side of each conductive sheet (2) is respectively connected with the stainless steel screw cap (1) through screw threads, and the conductive wires (5) are fixed between the conductive sheets (2) and the stainless steel screw cap (1). The novel molten salt temperature switch of the invention is applicable to the environment temperature between 170 and 1000 DEG C, and has the characteristics of high corrosion resistance, low requirements on use environment and certain extruding and pressing capability, capability of circulated use, long service, small size and the like. The conductive media adopted by the invention are molten salt systems with high stability and notoxicity.

Description

technical field [0001] The invention belongs to the technical field of temperature switches, in particular to a novel molten salt temperature switch and a preparation method thereof. Background technique [0002] The current temperature switches are divided into solid expansion temperature switches in the temperature range of 0°C to 100°C; gas expansion temperature switches are mostly used in the temperature range of 100°C to 250°C; for temperatures above 250°C For the temperature range, only thermocouples or thermal resistance thermometers can be used, which are converted into analog electrical signals by measuring transmitters, and then converted into digital signals. In higher temperature working areas, existing temperature switches are uneconomical or even impossible to use. Contents of the invention [0003] In order to overcome the defect that the above-mentioned temperature switch is not suitable for higher temperatures, the present invention proposes a new type of...
