Electrode sealing device

Abstract

The invention belongs to the technical field of cabin-penetrating sealing, and particularly relates to an electrode sealing device which is characterized in that a lead of which the upper end and the lower end are respectively sleeved with an upper pressing screw tube and a lower pressing screw tube is arranged in a cabin-penetrating pipe fitting in a penetrating manner, and the cabin-penetrating pipe fitting and a sealing element arranged between the upper pressing screw tube and the lower pressing screw tube are extruded by the upper pressing screw tube and the lower pressing screw tube; according to the method, a sealing element is arranged on a cabin penetrating pipe fitting, so that the sealing element deforms at a certain angle relative to the cabin penetrating pipe fitting, a wire is extruded, sealed and fixed, meanwhile, plane sealing of the cabin penetrating pipe fitting, an upper pressing screw tube and a lower pressing screw tube is achieved through the deformed sealing element, and electrochemical measurement under the hydrostatic pressure condition is achieved through an electrochemical workstation connected with the wire; the device is simple in structure, stable, reliable, simple to replace and operate, reusable, low in cost and high in practicability, has the function of realizing an electrochemical test under the hydrostatic pressure condition, and can solve the problem of experiment failure caused by structural failure under the pressure condition.

Description

Technical field: [0001] The invention belongs to the technical field of piercing sealing, and in particular relates to an electrode sealing device, which can meet the sealing requirements under hydrostatic pressure. Background technique: [0002] In the process of electrochemical measurement under high-pressure hydrostatic pressure, the sealing of the electrode through the chamber is the most critical issue to carry out the electrochemical measurement under hydrostatic conditions. In the prior art, in order to ensure the stability of the penetration seal, the penetration electrode is designed as a whole. For example, a simulated ultrasonic-assisted wet welding experimental device disclosed in Chinese Patent No. 201811083012. system and power supply system, the pressure bulkhead is respectively provided with a first air intake pipe, a second air intake pipe and a pressure relief valve, and the air supply system is connected to the first air intake pipe and the second air inta...

AI Technical Summary

Problems solved by technology

The piercing electrode of the integral structure is connected to the autoclave by means of flanges, bolts or welding. One test sample matches a piercing structure, which makes the piercing structure unable to be reused, which affects the experiment process, and the cost is high. Electrochemical testing under stress causes great confusion

Therefore, research and design an electrode sealing device suitable for hydrostatic pressure conditions, to avoid the problem of experimental failure caused by structural failure under pressure conditions
