Referring to fig. 2, the working process of the existing building gas pressure regulating tank or building gas pressure regulator 60 installed on the technical solution of the present patent application is as follows: the building gas pressure regulating tank or the building gas pressure regulator 60 is connected with the intelligent connector of the building pressure regulating tank into a whole through the connecting bolt, so that the existing common building gas pressure regulating tank or the building gas pressure regulator 60 becomes an intelligent pressure regulator. The gas enters the intelligent connector of the building pressure regulating tank through the gas inlet pipe 91, enters the motor valve 6 after passing through the filter cartridge 4, the motor valve 6 is normally open, enters the building gas pressure regulating tank or the building gas pressure regulator 60 through the pressure regulator connecting flange 7, and enters the gas outlet pipe 92 through the gas outlet end of the building gas pressure regulating tank or the building gas pressure regulator 60. The principle of realizing intelligent operation is as follows, because the motor valve 6 of the technical scheme is positioned at the rear of the gas flow direction of the filter cartridge 4, an upstream pressure transmitter 81 is fixed on the side wall of the gas inlet flange seat 3, the upstream pressure transmitter 81 is used for collecting the pressure in the inner cavity of the gas inlet flange seat 3, and the upstream pressure transmitter 81 is electrically connected with the control box 9 with a PLC control sheet through a lead; a downstream pressure transmitter 82 is fixed on the side wall of the air outlet flange seat 11, the downstream pressure transmitter 82 is used for collecting the pressure in the inner cavity of the air outlet flange seat 11, and the downstream pressure transmitter 82 is electrically connected with a control box 9 with a PLC control sheet through a lead; when the downstream air pressure exceeds the set value, and if the mechanical cut-off valve of the building gas pressure regulating box or the building gas pressure regulator 60 fails, the downstream pressure transmitter 82 transmits an electric signal to the electronic board of the control box 9 with the PLC control sheet, the control box 9 with the PLC control sheet rapidly closes the motor valve 6, and alarms or remotely controls and processes through the APP on the control box 9 with the PLC control sheet, and the APP on the control box 9 with the PLC control sheet can also be other wireless signal transmission devices.
