Embodiment Construction
[0018] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.
[0019] Such as figure 1 , 2 As shown, a thermocouple installation structure includes an inner sleeve 1 and an outer cylinder 2 . The thermocouple is composed of a junction box, a protective sleeve 3, a resistor body and the like, which are prior art here and will not be repeated here. Scale lines are arranged on the thermocouple protection sleeve 3, and the interval between the scale lines is 2mm. An external thread is formed on the outer wall of the thermocouple protection sleeve 3, and a nut 4 is threadedly installed on the protection sleeve 3, and a connecting plate 5 is sealed and welded on the lower end of the nut 4, and a connecting plate 5 is opened on the connecting plate 5. There is a through hole through which the thermocouple protection sleeve 3 can pass. The lower end of the connecting plate 5 is sealed and welded with a hollow ...

The invention provides a thermocouple installation structure. The thermocouple installation structure comprises an inner sleeve and an outer cylinder; an external thread is arranged on the outer wallof a thermocouple protection sleeve; a nut is arranged on the protection sleeve; a connecting plate is in sealed welding at the lower end part of the nut; a through hole for the thermocouple protection sleeve to pass through is formed in the connecting plate; a hollow threaded pipe is welded at the lower end part of the connecting plate; an external thread is arranged on the outer wall of the hollow threaded pipe; a through hole, into which the hollow threaded pipe can be inserted, is arranged in the inner sleeve; an internal thread is arranged on the inner wall of the inner sleeve; the outercylinder is provided with a through hole for the inner sleeve to pass through; a plurality of support devices are arranged on the side wall of the outer cylinder; the support device comprises a support rod rotatably installed on the side wall of the outer cylinder through a rotating shaft; and a torsional spring is installed on the rotating shaft. By means of the installation structure, the arbitrary height required by a thermocouple to stretch into a pipeline can be adjusted rapidly and precisely; and furthermore, the thermocouple is stably installed on the pipeline.
Description
technical field [0001] The invention relates to the field of thermocouples, in particular to a thermocouple installation structure. Background technique [0002] A thermocouple is a temperature-sensing element and an instrument that 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). In the prior art, the installation methods of thermocouples include flange type, nut type, etc., and the length of the thermocouple inserted into the pipeline cannot be adjusted during installation, and once the thermocouple is fixed, it is difficult to adjust again. Therefore, it is an urgent problem to develop a thermocouple installation structure that is convenient for installation and adjustment. Contents of the invention [0003] The present invention solves the above technical problems and provides a thermoco...
