Embodiment Construction
[0020] Below in conjunction with the drawings, preferred embodiments of the present invention are given and described in detail.
[0021] Such as figure 1 As shown, the high temperature thermocouple sleeve structure according to a preferred embodiment of the present invention includes a first sleeve 1, a thermocouple 2, and a heat conduction head 3, wherein the heat conduction head 3 is fixedly arranged at the bottom of the first sleeve 1, and the thermoelectric The pair 2 passes through the first sleeve 1 and extends into the thermal conduction head 3 . In particular, the heat-conducting head 3 is formed of a heat-conducting metal, such as copper, so as to transmit the sensed external temperature to the thermocouple 2 .
[0022] The first casing 1 includes a side wall 11 , a first sealing head 12 and a gas pipeline 13 , wherein the bottom of the side wall 11 is closed by the heat conduction head 3 , and the top of the side wall 11 is closed by the first sealing head 12 . In...

The invention relates to a high-temperature thermocouple sleeve structure, which comprises a first sleeve, a heat conducting head and a thermocouple, wherein the first sleeve comprises a side wall, afirst seal head, a gas pipeline and an automatic locking device arranged on the gas pipeline, the top of the side wall is closed by the first seal head, the side wall is composed of an inner wall andan outer wall which are separated by a chamber, and the gas pipeline is communicated with the chamber; the heat conducting head is used for closing the bottom of the side wall of the first sleeve; andthe thermocouple penetrates through the first sleeve and extends into the heat conducting head, the thermocouple located outside the first sleeve is fixedly provided with a positioning bolt group, and the automatic locking device of the first sleeve is matched with the positioning bolt group. The high-temperature thermocouple sleeve structure can accurately fix the bottom end of the thermocoupleat a designed position for a long time through the cooperation of the automatic locking device and the positioning bolt group, thereby ensuring the temperature measured by the thermocouple is the temperature of a required measuring point.
Description
technical field [0001] The invention relates to temperature measuring equipment for a high-temperature molten salt reactor, and more particularly relates to a high-temperature thermocouple casing structure. Background technique [0002] The molten salt in the high-temperature molten salt reactor is highly corrosive, and it is easy to corrode the equipment and measuring instruments in contact with it, resulting in damage to the equipment and measuring instruments. Therefore, when measuring the temperature of molten salt, a thermowell is required to protect the measuring equipment. [0003] Since the working temperature of the molten salt reactor reaches more than 700 degrees Celsius, the thermocouple and the thermocouple sleeve are installed at room temperature. As a result, the measured temperature does not reflect the actual temperature at the point, which interferes with the judgment of the operating status of the equipment and may lead to serious accident consequences. ...
