Welded gas cylinder is a high-pressure container specifically designed for storing and transporting gases used in the welding process, such as oxygen, acetylene, argon, carbon dioxide, etc. The design and manufacturing of welded gas cylinders must comply with strict safety standards to ensure that there are no hazards such as leaks or explosions during use. To ensure the safety of welding gas cylinders, regular inspections of the cylinders are necessary.
Welding gas cylinder testing equipment is mainly used to test the safety, sealing, and service life of gas cylinders, ensuring that they will not leak or encounter other dangerous situations during use. According to different testing items, there are various common welding gas cylinder testing equipment. The cylinder valve calibration table is a device specifically used in welding gas cylinder testing equipment to detect and calibrate gas cylinder valves, ensuring that the gas cylinder valves can be opened, closed, and sealed normally during actual use. The function of the cylinder valve directly affects the safety of the gas cylinder, so it is very important to calibrate it. The cylinder valve calibration station usually has the following functions.
1. Sealing test
The bottle valve calibration station uses pressurization to test the sealing performance of the gas cylinder valve, ensuring that there will be no gas leakage when the valve is closed.
2. Pressure verification
This function is used to detect the pressure required for the valve of the gas cylinder to open, ensuring that the valve opens under normal working pressure conditions. Test whether the pressure of the gas cylinder valve when closed meets the requirements, ensuring that the gas can be safely sealed without reaching the pressure when closed.
3. Voltage withstand test
Check whether the gas cylinder valve can withstand specific working pressures without deformation or damage, ensuring its durability and safety in practical operation.
4. Durability testing
By repeatedly opening and closing the bottle valve, check whether its performance decreases after long-term use, especially in terms of sealing and operational sensitivity.
5. Safety valve function testing
For gas cylinder valves with safety valve function, the calibration bench can detect their overpressure release function to ensure that when the pressure inside the gas cylinder exceeds the safety limit, the safety valve can work in a timely manner, release excess pressure, and prevent explosions or other safety accidents.
Verify the operational flexibility of the bottle valve to ensure that it can be operated normally during the use of the gas cylinder, without jamming or excessive looseness.
The bottle valve calibration station is usually equipped with precision pressure sensors, temperature sensors, flow meters and other detection equipment to ensure the accuracy and reliability of test data. Through these verification processes, it can be ensured that the valve of the gas cylinder can maintain a stable and safe operating state for a long time in actual use.
