Abstract

The invention relates to a multipoint temperature measuring interface device of a vacuum furnace. The interface device comprises flange locknuts, temperature measuring thermocouples, a flange cover and multipoint temperature measuring pipes. The flange cover is provided with outer holes and inner holes, the multipoint temperature measuring pipes are connected to the outer holes in the bottom of the flange cover and penetrate into the flange locknuts to be fixed, the temperature measuring thermocouple are connected into the inner holes in the flange cover and provided with inductors, fixing bases are installed at the inner holes, locking threads are arranged on the outer sides of the fixing bases and fixedly connected with the inner holes, hollow round pipes are arranged in the centers of the fixing bases, the temperature measuring thermocouples are connected with the insides of the hollow round pipes, oblique openings are formed in the inner sides of the pipe openings of the hollow round pipes, O-shaped sealing rubber rings are placed in the oblique openings, spacers are installed at the top ends of the fixing bases and are fixedly sealed through sealing lock nuts, gaps between the temperature measuring thermocouples and the flange cover can be well fixedly sealed through the fixing bases, and the effect of reducing temperature measuring errors is achieved.

Description

technical field [0001] The invention relates to the technical field of temperature measurement, in particular to a vacuum furnace multi-temperature measurement interface device. Background technique [0002] High-temperature vacuum furnaces are used in many occasions in modern industry. The control of the internal temperature is closely related to the quality of the products produced. Therefore, the measurement and monitoring of the furnace temperature of high-temperature vacuum furnaces is an important means of controlling product quality. Flanges are usually used Connect the temperature measuring thermocouple in the furnace and the test instrument outside the furnace in the form of a disc. There are binding posts on the flange. According to the standard requirements, the effective heating area adopts a three-dimensional measurement method, and thermocouples are evenly distributed in any plane in the effective heating working space. There is a temperature measuring port un...
