Embodiment Construction
[0045] The present patent will be described in detail below with reference to the accompanying drawings and specific embodiments.
[0046]In this embodiment, the high temperature and high pressure multi-point temperature measuring device provided by the present invention includes two parts: a temperature measuring probe and a base. figure 1 , figure 2 .
[0047] After the temperature measuring probe is inserted downward into the base, it is the final assembly effect of the device of the present invention, see image 3 .
[0048] The temperature measurement probe includes at least two armored thermocouples, an upper sealing nut 1, a connecting nut 2, a lower sealing nut 3, a probe tube 4, two positioning pins 5, a compression pad 6 and two thermoelectric Even gasket 7. Among them, the upper sealing nut 1 and the lower sealing nut 3 are respectively connected with the upper part and the lower part of the connecting nut 2; the inner end face of the upper end of the upper sea...

The invention discloses a high temperature and high pressure multi-point temperature measuring device, which comprises two parts of a temperature measuring probe and a base; the temperature measuring probe comprises at least two armored thermocouples, an upper sealing nut, a connecting nut, a lower sealing Nut, probe tube, two positioning pins, pressing pad and two thermocouple sealing pads; the base includes fixing nut, pressing nut, fixing seat, fixing ring, base pressing pad and probe sealing ring . The device of the present invention is compact in structure, consistent in size from top to bottom, occupies a small space, and can meet the demand for multi-point temperature measurement in a narrow space; multiple seals are set in the present invention, and the sealing method is extrusion sealing, so it can be Adjust the insertion depth of the temperature measuring probe or a single armored thermocouple multiple times, that is, the position of the measuring point can be adjusted easily; in addition, the thermocouple temperature measuring head is directly in contact with the measured medium, and the temperature response is sensitive; the armored thermocouples are fixed separately and not mutually The contact avoids the measurement error caused by mutual contact in the prior art.
Description
technical field [0001] The patent of the invention belongs to the technical field of mechanical devices, and relates to a high temperature and high pressure multi-point temperature measuring device. Background technique [0002] High temperature and high pressure fluids are widely used in industrial boilers and nuclear energy systems. The working parameters of fluids such as temperature and pressure have a significant impact on system safety and energy conversion efficiency. The conventional temperature measurement method has only one temperature measurement element, which can only measure the temperature of a certain point. For some scenarios with temperature gradients, multiple temperature measurement devices need to be installed, which takes up a lot of space and is difficult to arrange. In addition, for some places with small space and intensive temperature measurement requirements, the installation of multiple thermocouples can easily interfere with the flow field, resu...
