Technical Field

The invention relates to a threading device, in particular to a sealing threading device for a high-pressure wall surface.

Background

In many pressure vessel applications, it is necessary to transmit power to the equipment within the vessel and to effectively monitor the conditions within the vessel (e.g., temperature, pressure, etc.), and then signal or power lines need to be run through the pressure vessel. One of the important problems is to safely pass a signal line or a power line through the pressure-resistant tank without damaging the sealability of the pressure-resistant tank.

Taking the study of the combustion behavior of hydrogen in a closed pressure-resistant tank as an example, it is necessary to measure signals such as temperature and pressure in a pressure vessel in order to directly reflect the characteristics of hydrogen at the time of deflagration and recombination. In the test, a thermocouple, a pressure probe, and the like are arranged inside a pressure vessel, and signal acquisition is performed outside the pressure vessel. Therefore, certain devices and practical processes need to be designed, and cables are led out through the wall surface of the pressure container while the sealing of the pressure container is ensured not to be damaged.
