Double multi-point thermocouple

Abstract

The invention discloses a double-branch multi-point thermocouple, which includes a mounting flange, fixed suspension rings are provided on both sides of the mounting flange, a triangular block fixing seat is provided on the top of the mounting flange, and a second sealing seat is provided on the top of the triangular block fixing seat. The top of the second sealing block is provided with a sealing chamber block, and the top of the sealing chamber block is provided with a first sealing block. The beneficial effects of the present invention are: the present invention has a novel structure and a compact internal structure. The invention has the characteristic of losing one temperature measuring point and other temperature measuring points can still work normally, while the imported product loses one temperature measuring point and is scrapped as a whole. In the production process, the temperature and pressure control and sensitivity of the device are well controlled, and the produced The device has high precision, high stability, and high pressure resistance. It can not only prevent the harm to people caused by the leakage of toxic, inflammable and explosive gases, but also has a low price and short delivery period, which provides a great guarantee for people's normal use. Convenience; in addition, the present invention is more convenient for timely replacement and repair when the temperature measuring point is damaged, which provides convenience for the staff, so as not to affect the normal progress of the work.

Description

technical field [0001] The invention relates to the technical field of thermocouples, in particular to double-branch multi-point thermocouples. Background technique [0002] In daily life, a thermocouple is a commonly used temperature measuring element in a temperature measuring instrument. It directly measures the temperature and converts the temperature signal into a thermal electromotive force signal, which is converted into the temperature of the measured medium through an electrical instrument (secondary instrument). The shapes of various thermocouples are often very different due to needs, but their basic structures are roughly the same, usually composed of main parts such as thermal electrodes, insulating sleeve protection tubes, and junction boxes, and are usually associated with display instruments, recording instruments, and electronic regulators. used together with the device.

AI Technical Summary

Problems solved by technology

[0003] At present, there are many synthesis devices in various domestic chemical energy enterprises. During the production process, the temperature and pressure control of the devices are extremely sensitive. A little temperature deviation will have a chain reaction on the device, causing the device to stop and cause huge losses. The principle of the synthesis tower is that a variety of gases are synthesized at high temperature and high pressure in the reactor. Among them, various gases such as toxic, flammable and explosive gases need to be tightly blocked by the temperature measuring device. It can only be produced safely; once it leaks, it will easily cause casualties; at present, imported products are mostly used in China, which are expensive and have a long delivery cycle and cannot meet the actual needs of enterprises; in addition, the temperature measurement points of traditional devices for key parts are damaged It cannot be replaced in time, which will cause great inconvenience to the work and affect the normal progress of the work.
