As a device specially used to control or cut off the gas flow in the vacuum pipeline, the vacuum valve is widely used and important. The following details the common uses of vacuum valves from a number of areas:
First, the field of industrial manufacturing
1. Semiconductor manufacturing:
Vacuum valves are used for isolation, control and transmission in semiconductor manufacturing. Because the vacuum environment is basically throughout the semiconductor manufacturing process, vacuum valves are widely used in vacuum systems, such as process chamber gas control.
– Vacuum valves can precisely control gas flow and pressure, ensure the purity and stability of the manufacturing environment, and improve product yield and production efficiency.
2. Electronics Industry:
In the manufacture of electronic components, vacuum valves are used to control atmospheric pressure and remove impurities from the air, thereby increasing production efficiency and reducing product defect rates.
Vacuum valves are also used to clean circuit boards and semiconductor devices, pushing out air and dust through tiny jets to ensure a clean production environment.
Second, the pharmaceutical industry
– In the pharmaceutical process, the vacuum valve effectively controls the number of bacteria in the air by discharging impurities such as oxygen and water vapor to avoid contamination of the product.
– Vacuum valves are also used for powder transmission, transporting the powder from one container to another, reducing the impact of air on the drug and ensuring the quality of the drug.
Third, the aerospace sector
– In the space industry, vacuum valves are used to maintain the low pressure in the space capsule and ensure the normal operation of the spacecraft.
There are also several small areas in the aircraft engine that need to be adjusted by vacuum valves to ensure the normal operation and performance of the engine.
Fourth, the field of laboratory research
– In laboratory research, vacuum valves are used to control the vacuum state in reactors and test tubes to facilitate observation and control of the reaction process.
– Vacuum valves can reduce gases and impurities in the reactor, improving the accuracy and repeatability of the experiment.
Fifth, other application areas
1. Fire, swimming pool, green irrigation, water supply and drainage, dock, power plant, metallurgy, shipbuilding and other fields:
– The vacuum valve absorbs the air protection system in time when the system forms negative pressure to prevent damage to pipelines or other equipment due to excessive negative pressure.
– In the protection of steam heat exchange equipment, the vacuum valve automatically opens after the steam stops, introduces air or other fluids, eliminates the vacuum in the equipment, and protects the safety of the equipment.
2. Drinking water pipeline:
– Vacuum valve is used to automatically eliminate the vacuum in the pipeline, prevent siphon backflow phenomenon, and ensure the water quality safety of drinking water system.
3. Automobile Manufacturing:
The vacuum valve plays an important role in the engine system of the car, such as the intake vacuum solenoid valve, which inhales the air into the engine and mixes the fuel to burn, ensuring the normal operation of the engine.
To sum up, vacuum valves play an important role in industrial manufacturing, pharmaceutical, aerospace, laboratory research and daily life because of their unique control functions and a wide range of application fields. With the continuous progress of industry and science and technology, the application range of vacuum valves will continue to expand, and its importance will become increasingly prominent.
