Double-branch multi-point thermocouple

Abstract

The invention discloses a double-branch multi-point thermocouple which comprises a mounting flange, fixed hanging rings are arranged on the two sides of the mounting flange, a triangular block fixing seat is arranged at the top of the mounting flange, a second sealing block is arranged at the top of the triangular block fixing seat, a sealing cavity block is arranged at the top of the second sealing block, and a first sealing block is arranged at the top of the sealing cavity block. The thermocouple has the advantages that the structure is novel, the internal structure is compact, compared with imported similar products, the thermocouple can still work normally without one temperature measuring point and other temperature measuring points, the whole imported product is scrapped without one temperature measuring point, control over the temperature and pressure of the device and sensitive control over the device are good in the production process, the produced device has high precision, high stability and high pressure resistance, not only can prevent harm to people caused by leakage of various gases such as toxic, flammable and explosive gases, but also is low in price and short in delivery cycle, and provides convenience for normal use of people; in addition, the temperature measuring point can be replaced and repaired in time more conveniently when damaged, convenience is provided for workers, and therefore the normal progress of work is not affected.

Description

technical field [0001] The invention relates to the technical field of thermocouples, in particular to double fulcrum multi-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.

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.
