Description

Technical Field

[0001] This utility model generally relates to the field of lithium battery technology. More specifically, this utility model relates to a sealing valve. Background Technology

[0002] Valves are pipeline accessories used to open and close pipelines, control flow direction, and regulate and control the parameters (temperature, pressure, and flow rate) of the transported medium. In fluid transport systems, they have functions such as shut-off, regulation, flow diversion, backflow prevention, pressure stabilization, flow splitting, or overflow pressure relief. Valves are commonly used to control the flow of various types of fluids, including air, water, steam, various corrosive media, slurry, oil, liquid metals, and radioactive media.

[0003] In the lithium battery drying process, valves are needed to control the vacuum level inside the baking chamber. However, due to the pressure difference between the inside and outside of the baking chamber, the valves themselves heat up rapidly when they are working, making traditional valves unsuitable for the above environment.

[0004] In view of this, there is an urgent need to provide a sealing valve to solve the problem. Utility Model Content
