[0002] It is pointed out in the related art that the temperature measurement of the fluid in the tube of the heat exchanger or other fluid pipelines is generally measured by setting a temperature measuring device at the inlet and outlet of the heat exchange tube or at individual points in the tube, and the measured data cannot reflect the overall temperature in the tube. At the same time, the sealing device of the through hole on the pipe wall of the general pipe is difficult to apply to the pipe under the high temperature and high pressure environment in the pipe

Abstract
The invention discloses a sealing device for a small penetration part on a cavity and a heat exchanger with the sealing device. Lead-out holes are formed in the cavity; the sealing device comprises a clamping seat and a sealing part, wherein the clamping seat is fixed to the outer side of the cavity and connected with the outer wall of the cavity in a sealed manner; a sealing cavity is formed in the clamping seat; the sealing part is arranged in the sealing cavity; a lead-out channel is defined in the sealing part and is a labyrinth lead-out channel; an inlet of the lead-out channel is opposite to and communicates with the lead-out holes; and one end, facing the lead-out holes, of the sealing part is connected with the clamping seat and / or the periphery of the lead-out holes in a sealed manner. According to the sealing device for the small penetration part on the cavity, the lead-out holes of the cavity can be well sealed, and meanwhile, the internal structure of the sealing device can ensure that the sealing device has good sealing performance, thereby ensuring that medium leakage does not occur when the penetration part is led out of the cavity.
Description
technical field [0001] The invention relates to the technical field of thermal hydraulics of reactors, in particular to a sealing device for a small penetrating part on a cavity and a heat exchanger having the same. Background technique [0002] It is pointed out in the related art that the temperature measurement of the fluid in the tube of the heat exchanger or other fluid pipelines is generally measured by setting a temperature measuring device at the inlet and outlet of the heat exchange tube or at individual points in the tube, and the measured data cannot reflect the overall temperature in the tube. At the same time, the sealing device of the through hole on the general pipe wall is difficult to apply to the pipe under the high temperature and high pressure environment in the pipe. Contents of the invention [0003] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, the present invention proposes a seal...
