[0002] Vacuum valves are used in high vacuum or ultra-high vacuum system equipment. When vacuum must be maintained in a closed vacuum processing system, vacuum valves are used to control the gas flow into the vacuum chamber, isolate, exhaust, provide pressure relief or control conduction. Gate valves and angle valves are common types of vacuum valves used in high vacuum or ultra-high vacuum applications.

[0003] After a long period of use, the internal parts of the vacuum drain valve are easily damaged due to long-term immersion in water, and regular maintenance is required to prevent the vacuum drain valve from being unable to be used normally due to damage to the parts.
