Abstract

The invention provides a high-temperature and high-pressure sealing device for small optical fiber sensor test. The sealing device is characterized in that the sealing device comprises a cylindrical or rectangular high-pressure tank, a sealing cover, a bolt, a bolt and a thermotank; the side wall of the high-pressure tank is provided with a circular hole, and an optical fiber sensor is arranged in the high-pressure tank; the sealing cover covers the high-pressure tank, and the center of the sealing cover is provided with a screw hole; the bolt is matched with the screw hole on the sealing cover, and the longitudinal center of the bolt is provided with a through hole; the pressure pump is connected with the circular hole on the side wall of the high-pressure tank through a pipeline; and the high-pressure tank is arranged in the thermotank.

Description

technical field [0001] The invention relates to the field of sensor testing, in particular to a high-temperature and high-pressure experimental device for small sensors. Background technique [0002] Special small sensors, especially fiber-optic temperature and pressure sensors with high temperature and high pressure characteristics, can be widely used in national defense, security monitoring, oil exploration and other fields, so they have attracted more and more attention from relevant companies and research institutions. [0003] However, for a long time, in the field of small sensor experiments and research, there has been no experimental device that can safely and conveniently perform repeated high temperature and high pressure sealing on small sensors. [0004] At present, the commonly used methods of applying temperature and pressure to the sensor are: heating the sensor through a water bath, putting the sensor in oil for high-temperature experiments; pressurizing the ...
