Hello, my commercial gas regulator. Can you tell me how to adjust the output pressure?

The structure and principle of the voltage regulator are similar.

Generally, there are adjusting screws or adjusting screw rings to adjust the air pressure. If you use it at home, you usually use a medium and low voltage direct-acting voltage regulator. The adjusting screw or adjusting ring of the pressure regulator is located at the top of the actuator (that is, the diaphragm).

If you want to increase the air pressure, just turn the adjusting screw or ring clockwise, but when adjusting, there must be a pressure gauge at the outlet. While observing the reading change of the pressure gauge, slowly adjust it. It is recommended to turn 1/4 turns at a time, because when the voltage regulator increases, there will be a process of pressure increase, not immediately after adjustment, and it is necessary to adjust it slowly while observing, so as to avoid overpressure caused by excessive action.

The import of 0.3, if the unit is bar, is really small. Your pre-pressure should come from the medium pressure pipe network. Generally, the normal medium pressure pipe network is around 2bar.

Finally, it is recommended not to adjust yourself.

Let's contact the people in the gas company and reflect the situation.

Because the operation of the pressure regulator has been adjusted according to the design pressure to ensure the outlet air pressure during normal gas supply, if the outlet air pressure is not enough because the inlet air pressure is too low and the set value is changed by private operation, people in the gas company will not be aware of it. Once the air intake returns to normal, the outlet air pressure of the pressure regulator with increased set value will also rise, which may cause the danger of overpressure! ! ! ! ! ! ! ! ! ! ! ! !
