What are the Application Scenarios and Precautions for the 2BX Series Safety Valves?

I. Application Scenarios

Pressure Protection for Side Channel Blowers
The 2BX series safety valve is specifically designed for side channel blowers. It can be installed at the blower's inlet or outlet to prevent equipment damage caused by overpressure or pressure surges. It is suitable for industrial scenarios requiring stable air pressure control, such as pneumatic conveying, wastewater treatment, and food processing.

Overpressure Protection in Vacuum Systems
This safety valve is not only suitable for positive pressure environments but can also operate under vacuum conditions. When internal pressure abnormally increases due to failure or operational error in a vacuum system, the safety valve can automatically relieve pressure, protecting the vacuum pump and piping system.

Pressure Fluctuation Buffering in Industrial Processes
In process industries such as chemical and pharmaceutical, where process media pressure fluctuates frequently, the 2BX series safety valve can maintain system pressure stability through rapid response (opening within 0.2 seconds), avoiding production accidents caused by sudden pressure changes.

Scenarios Requiring High-Precision Pressure Relief Control
Model 2BX4 offers a pressure relief repeatability accuracy of 5%, making it suitable for scenarios with strict pressure control requirements, such as laboratory equipment and precision instrument gas supply systems, ensuring controllable pressure fluctuation ranges.

Reliable Protection in Harsh Operating Conditions
The all-metal construction (spindle, adjusting nut, and spring are steel; other components are aluminum alloy) provides corrosion resistance and high-temperature tolerance. It is suitable for high-temperature, humid, or corrosive gas environments, such as offshore platforms and mine ventilation.

II. Precautions

Installation Position and Direction

The safety valve must be installed vertically on the inlet or outlet pipeline of the side channel blower, ensuring an unobstructed pressure relief path.
Avoid installation at pipe bends or near valves, flanges, or other areas that may generate turbulence, as this can affect pressure relief accuracy.

Regular Calibration and Maintenance

Check the set pressure and reseating pressure of the safety valve every 6 months to ensure they meet the set values (error ≤ 5%).
Clean impurities inside the valve body to prevent malfunction or leakage due to clogging.
When replacing worn springs or seals, use genuine parts to guarantee performance.

Pressure Setting and Adjustment

During initial installation or pressure adjustment, use special tools to slowly rotate the adjusting nut to avoid equipment damage from sudden pressure changes.
The set pressure should be slightly higher than the system's normal operating pressure (typically 5%-10% higher) but must not exceed the blower's maximum rated pressure.

Avoiding Misoperation and Human Damage

Do not forcibly close or disassemble the safety valve while it is in the open state, as this may damage the disc or spring.
Operators must receive professional training and be familiar with the safety valve's operating principle and emergency procedures.

Compatibility Verification

Before selecting a 2BX series safety valve, confirm that its materials (e.g., aluminum alloy components) are compatible with the process media to avoid chemical reactions leading to corrosion or leakage.
For high-temperature applications (>100°C), confirm the spring's temperature resistance with the manufacturer in advance and select a model with special materials if necessary.

Emergency Response and Recording

If the safety valve opens frequently, immediately check the system for pressure abnormalities (e.g., pipeline blockage, blower failure) and record the number of relief events and pressure values for analysis.
After each pressure relief event, check the valve's sealing performance to prevent secondary leakage caused by residual media.

III. Summary

The 2BX series safety valve, with its all-metal structure, high-precision pressure relief, and suitability for both positive and negative pressure, serves as a critical protection device for side channel blowers and vacuum systems. Through proper selection, standardized installation, and regular maintenance, it can significantly enhance equipment operational safety and extend service life. Users must strictly adhere to operating specifications to avoid system risks caused by misuse or negligence.
