Safety valve is a key component in industrial equipment, which functions to automatically open when the system pressure exceeds the set value, release excess pressure, and prevent equipment from exploding or other dangerous situations. It plays a role in preventing excessive pressure and protecting equipment and personnel safety. Safety valve calibration is the process of testing and calibrating safety valves to ensure that they can open normally under the set pressure, thereby protecting the safety of equipment and systems. The automatic calibration table for safety valves is a device specifically designed for calibrating and testing the performance of safety valves.
Regular calibration of safety valves is an important measure to ensure the safe operation of equipment and systems. The frequency of verification is usually determined based on the usage conditions of the equipment and relevant regulatory requirements. The main items for safety valve calibration are as follows:
Appearance inspection: Check the appearance of the safety valve to ensure that there are no mechanical damage, corrosion, or other defects that affect normal operation.
Dismantling and Cleaning: Remove the safety valve from the equipment and clean it to ensure that there is no dirt or impurities inside the valve body.
Spring force verification: Test and adjust the spring force of the safety valve to ensure that it can open normally within the set pressure range.
Open pressure test: Use calibration equipment to perform a pressure test on the safety valve, record its actual opening pressure, and compare it with the design value. If it does not meet the requirements, maintenance and adjustment are required.
Sealing inspection: After closing the safety valve under the set pressure, check its sealing to ensure that there is no leakage under normal working pressure.
Reinstall and Test: Reinstall the verified safety valve onto the equipment and conduct operational testing to ensure its normal operation under actual working conditions.

The safety valve calibration bench can simulate working environments under different pressure conditions and test the opening and closing pressure of the safety valve. Evaluate the sealing performance of the safety valve under specified pressure to ensure that the valve does not leak. Through multiple opening and closing tests, verify the stability of the safety valve's operation under long-term working conditions. Most modern calibration stations are equipped with automated control systems that can automatically complete the testing process and generate detailed testing reports. Being able to record data from each test and provide analysis tools to help users evaluate the performance and reliability of safety valves. The main components are.
Pressure source: Provides a stable source of air pressure or hydraulic pressure, which can be adjusted to the required test pressure as needed. Common sources of pressure include air compressors, water pumps, etc.
Control system: including pressure control valves, regulating valves, flow controllers, etc., used for precise regulation and control of the pressure required during the testing process. Modern calibration stations are usually equipped with automated control systems that can be controlled through computer programs, simplifying operations and improving testing accuracy.
Data acquisition and analysis system: Real time monitoring and recording of key data such as opening pressure, reseating pressure, and leakage of safety valves through sensors and data acquisition devices. These data can be automatically generated into reports for operators to analyze and record.
Test bench: used to fix and install safety valves to ensure that they are stable and free from shaking during the testing process. Can adapt to safety valves of different sizes and types.
Sealing system: During the testing process, the sealing system is used to prevent medium leakage and ensure the safety and accuracy of the testing process.
The automatic calibration table for safety valves is widely used in industries such as petroleum, chemical, metallurgy, and power. It is used for regular inspection and maintenance of safety valves in the production process to ensure the safety and reliability of equipment operation.
