Beschreibung
Zusammenfassung:	The unattended natural gas pressure regulating device comprises a valve, a gas inlet pipe, a filter screen, cleaning brushes and a rotating mechanism, the gas inlet pipe is arranged at one end of the valve, the filter screen is arranged in the gas inlet pipe, the cleaning brushes are arranged on the two sides in the filter screen in the diameter direction of the filter screen, and the cleaning brushes are connected with the rotating mechanism. And the rotating mechanism is used for driving the cleaning brush to rotate around the center of the filter screen so as to clean blockages on the filter screen. The unattended natural gas pressure regulating device provided by the invention has the beneficial effects that the rotating mechanism is used for driving the cleaning brush to rotate around the center of the filter screen so as to clean blockages on the filter screen, so that the situation that a valve is blocked due to the fact that many sundries are accumulated on the filter screen after the filter screen is
