Description

Technical Field

[0001] The utility model relates to the technical field of temperature measuring equipment, in particular to a contact type thermocouple temperature measuring instrument. Background Art

[0002] Thermocouples work by converting temperature signals into thermoelectric potential signals, which can then be converted into the actual temperature of the measured medium by electrical instruments. The basic structure of a thermocouple includes hot electrodes, insulating sleeve protection tubes, and junction boxes.

[0003] The installation of thermocouples is generally fixed on the external temperature-measured equipment by a fixing part installed on the outside of the thermocouple protective cover, such as the Chinese utility model patent disclosed by the publication number CN215832878U: a thermocouple installation and fastening device, the application uses a worm to rotate the rotating rod, drive the cam to rotate, so that when the cam contacts the movable plate, the movable plate is squeezed to move outward, drive the sliding rod to move outward, and the abutment plate moves outward until it abuts against the inner wall of the mounting hole to complete the installation. Although the application can fix the thermocouple tube on the equipment to be measured by the worm, worm gear, cam, abutment plate and other structures, the application only fixes it on the equipment to be measured by supporting it, and cannot seal the channel for installing the thermocouple on the equipment to be measured. In particular, when measuring the internal medium temperature of some pipes or other equipment with circulating medium, it is easy to cause the medium or heat inside the equipment to overflow, thereby affecting the normal use of the equipment to be measured. In addition, the sealing ring used for the installation of some existing thermocouples will affect the sealing effect due to the aging of the rubber material and the change of shape after a period of use.
