Anti-washout long-life liftable multi-point acquisition type thermocouple

Abstract

The invention provides an anti-washout long-life liftable multi-point acquisition type thermocouple. The anti-washout long-life liftable multi-point acquisition type thermocouple comprises a connecting box, an insulating pipe, a sliding column and a fastening sleeve; the sliding column glidingly sleeves the insulating pipe, and only can slide along the axis of the insulating pipe; multiple elasticpressure plates are circumferentially arranged on the sliding column; the elastic pressure plates are distributed around the insulating pipe; furthermore, a gap exists between the elastic pressure plate and the insulating pipe; an installation plate is arranged on the fastening sleeve; an external thread is arranged on the outer circumferential surface of the sliding column; an internal thread isarranged on the inner circumferential surface of the fastening sleeve; furthermore, a pressure ring is also arranged on the inner circumferential surface; the fastening sleeve sleeves the sliding column in a threaded manner, wherein the elastic pressure plate is positioned in the pressure ring; when the fastening sleeve rotates, the elastic pressure plate slides along the sliding column, and is near the pressure ring; the pressure ring can extrude the elastic pressure plate at the same time; and thus, the elastic pressure plate is elastically deformed, and tightly abuts on the insulating pipe. By means of the device in the invention, endless adjustment of the measurement end of the thermocouple can be realized; and thus, measurement requirements can be well satisfied.

Description

technical field [0001] The invention relates to the field of thermocouples, in particular to an anti-erosion high-life-span liftable multi-point collection thermocouple. Background technique [0002] 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. The shapes of various thermocouples are often very different due to needs, but their basic structures are roughly the same. They are usually composed of main parts such as thermal electrodes, insulating sleeve protection tubes and junction boxes, and require and display instruments, recording instruments and electronic devices. The regulator is used in conjunction with it. [0003] In the prior art, the thermocouple is usually installed on the equipment under test by bolts...
