The vacuum valve plays a crucial role in the vacuum system, and its characteristics can be summarized as follows:
1. Good sealing
The vacuum valve requires excellent sealing performance to effectively prevent gas penetration and leakage. The vacuum valve with good sealing can significantly improve the vacuum degree and maintain the stability of the system. In order to achieve this characteristic, the vacuum valve usually uses good sealing materials and structures, such as the design of the vacuum sealing structure packing chamber, with self-expansion and compression effect, so that the system is isolated from the atmosphere, so as to ensure a good system air tightness.
2. Valve operation is reliable
Vacuum valves need to be switched off and on frequently, so the reliability of valve operation is very important. Valve opening and closing should be accurate, smooth, and able to withstand high pressure. In addition, some vacuum valves also use scientific circuit control and electromagnetic circuit design, so that the solenoid valve coil always works in a state of high efficiency and power saving, thus ensuring the stability and reliability of valve operation.
3. Strong durability
Vacuum valves operate frequently and therefore require strong durability and long-term reliability. Vacuum valves are usually made of high-quality materials and go through strict production process and quality control standards to ensure the service life and stability of the valve. For example, the valve stem is tempered and surface nitriding treatment, with good corrosion resistance, abrasion resistance and wear resistance. At the same time, the flange gasket is made of composite material, which has large expansion coefficient and good airtight performance, further enhancing the durability of the valve.
4. Low resistance to airflow
The design of the vacuum valve also pays attention to reducing the resistance to the air flow, so that the flow conductance of the valve is as large as possible. This helps keep the vacuum system fluid and efficient.
5. Sealing parts have good wear resistance
The sealing parts of the vacuum valve need to have good wear resistance in order to be used repeatedly and maintain long-term sealing performance. This helps to extend valve life and reduce maintenance costs.
6. The valve body materials and seals are small
The valve body material and seal of the vacuum valve should have a small discharge volume to reduce the impact on the vacuum system. This is essential to maintain the vacuum and stability of the system.
7. Flexible operation, easy to clean and install
The design of the vacuum valve also focuses on the flexibility of operation, making the valve easy to clean and install. This helps simplify the maintenance process and increase maintenance efficiency.
8. Wide range of application
Vacuum valves are widely used in a variety of industrial production, especially in areas where the purity of the process environment and chemical and physical stability are particularly high requirements. For example, in the petrochemical industry, metallurgical machinery industry, nuclear industry and cutting-edge industries such as semiconductors, FPD, OLED, solar energy and other fields, vacuum valves play an important role.
To sum up, the vacuum valve plays a vital role in the vacuum system with its characteristics of good sealing, reliable valve operation and strong durability. At the same time, the design also pays attention to reducing the resistance to the air flow, improving the wear resistance of the sealing parts, reducing the valve body material and the discharge volume of the sealing parts, etc., to meet the needs of different fields.
