Abstract

The invention provides a thermocouple insulation sealing structure suitable for a narrow plate, and relates to the field of narrow plate detection. The structure comprises a narrow plate, a first insulating layer is arranged on the outer side of the narrow plate; a measuring hole is formed in the narrow plate; the opening end of the measuring hole penetrates through the first insulating layer; a sealing pipe is connected in the measuring hole; a thermocouple with an insulating layer is arranged in the sealing pipe; two sides of the thermocouple respectively penetrate through two sides of the sealing pipe; the measuring end of the thermocouple is connected to the bottom of the measuring hole, a second insulating layer is arranged on the outer side of the thermocouple, a third insulating layer connected to the thermocouple is arranged in the sealing pipe, and a sealing cover detachably connected to the sealing pipe is arranged at the end, away from the measuring hole, of the thermocouple. According to the invention, the insulation performance and the sealing performance of the thermocouple installed in the narrow plate are improved.

Description

technical field [0001] The invention relates to the field of narrow plate detection, in particular to a thermocouple insulation and sealing structure suitable for narrow plates. Background technique [0002] Narrow plate is a common part of thermal equipment, such as plate-shaped fuel elements, heat transfer parts of plate heat exchangers, etc. Thermocouple (thermocouple) is a commonly used temperature measuring element in temperature measuring instruments. It directly measures the temperature, and converts the temperature signal into a thermal electromotive force signal, and converts it 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, r...
