1.Before starting the gas pressure regulator, make sure that its inlet and outlet valves and bypass valves are closed;
2.Remove the blind plates at both ends of the regulator;
3.Before commissioning, the external pipeline should be purged to confirm that there is no mixed gas before ventilating operation;
4.Slowly open the inlet valve, connect the pressure gauge at one end of the double-ended Cork at the outlet side, and connect a hose at the other end to lead out of the box. Turn on the two-headed cocker, if you hear the sound of airflow, it proves that the device has been started. At this time, the output pressure of the gas pressure regulating tank can be adjusted to the required pressure according to the display of the pressure gauge. If there is a large difference between the output pressure and the required pressure without adjustment margin, the corresponding pressure regulating spring can be replaced to readjust the gas pressure regulating box;
5.Slowly close the end of the double-ended Cork hose, and observe whether the closing pressure displayed by the pressure gauge is normal. After the commissioning is qualified, slowly open the outlet valve of the gas pressure regulator box to start gas supply; if it is not normal, please overhaul the gas pressure regulator box according to the instruction manual, and then supply gas after the repair is qualified;
6.In the dual-channel gas pressure regulating box, debug the other channel from step 2; after the debugging is completed, close the inlet and outlet valves of the channel;
7.Gas pressure regulating box equipped with overpressure relief valve, after normal commissioning, adjust the overpressure relief valve. The release pressure is set at 1.3 times the output pressure, and the valves before and after the release valve are opened to ensure its normal operation;
8.A gas pressure regulating box equipped with an overpressure cut-off valve, the cut-off pressure is set at 1.5 times the output pressure. The box body of the gas pressure regulating box can be made into ordinary type or thermal insulation (heating) type according to the temperament. For dry, water-free qualities (such as natural gas, etc.), you can choose a common box. For gas qualities that contain water and are greatly affected by temperature changes (such as artificial coal gas, liquefied petroleum gas, etc.), you must select an insulated box to ensure the normal gas supply of the pressure regulating system.
