1. Check regularly whether the outlet pressure of the pressure regulator can meet the working requirements. If there is any abnormality, check and maintain it in time.
2. Check the closing pressure of the pressure regulator regularly. If the closing pressure is too high or leaks, check whether the main valve and pilot membrane of the pressure regulator are aged or damaged and clean the pressure regulator valve port.
3. Check the cut-off pressure of the cut-off valve regularly. If the cut-off pressure is too low, you should check whether the spring has lost its due strength or is broken and readjust the cut-off valve; if the cut-off pressure is too high or there is air leakage, you should check whether the cut-off valve membrane is aged and damaged. Check the closing characteristics of the block valve regularly. If the sealing is not tight after blocking, the valve port of the block valve should be checked and cleaned.
4. Check the safety relief valve condition and relief pressure regularly. If the relief pressure of the safety relief valve is too low or leaks, check whether the safety relief valve membrane is aged or damaged, whether the spring has lost its due strength or is broken, and clean the relief valve port; if the relief pressure is too high, the safety relief valve should be readjusted. Relief valve.
5. Replace the pressure regulator, cut-off valve, and safety relief valve membrane regularly. The cycle should depend on the gas quality.
6. Open the drain valve on the filter regularly to discharge dirt.
7. Clean the filter element regularly.
