Description

Technical Field

[0001] This application relates to the field of gas supply pipeline technology, and in particular to a highly reliable redundant gas supply pipeline. Background Technology

[0002] A gas distribution unit is a key piece of equipment that provides precise gas configuration and supply for aerospace propulsion systems. For example... Figure 1 As shown, the existing gas distribution platform's gas supply pipeline includes: a 35MPa nitrogen source inlet, a 35MPa nitrogen source vent outlet, a cylinder supply opening port, and a cylinder supply vent outlet. One end of the 35MPa nitrogen source inlet is connected to the nitrogen source via a pipeline, and the other end of the nitrogen source inlet is connected to one end of the filter via a pipeline. The other end of the filter is connected to one end of the manual valve JF12' via a pipeline. The other end of the manual valve JF12' is connected to one side of one end of the gas collection pipe via a pipeline. One side of the other end of the gas collection pipe is connected to the solenoid valve DF1' (wherein, the solenoid valve DF1' is a two-position, normally closed solenoid valve). The air supply inlet of the valve is connected; the air supply outlet of the solenoid valve DF1' is connected to the long-term purging air supply port; a pressure gauge P_N35' and a safety valve AF101' are also installed on the air collection pipe. The pressure gauge P_N35' (wherein, the measuring pressure range of the pressure gauge P_N35' is: 0-60MPa) and the safety valve AF101' (wherein, the opening pressure value of the safety valve AF101' is 38.5MPa) are connected to the solenoid valve DF1' and the manual valve JF12' through the air collection pipe; the pressure gauge P9' is connected to the long-term purging air supply port and the other end of the two-position normally closed solenoid valve DF1' through the pipeline. The 35MPa nitrogen source vent is connected to one end of the manual valve JF13', and the other end of the manual valve JF13' is connected to the other side of one end of the gas collection pipe through a pipeline; the gas supply inlet of the solenoid valve BD201' (wherein, the solenoid valve BD201' is a two-position three-position normally closed solenoid valve) is connected to the gas collection pipe, and the gas supply outlet of the solenoid valve BD201' is connected to the pressure sensor BP201' (wherein, the pressure measurement range of the pressure sensor BP201' is 0-10MPa) and the cylinder gas supply opening port through a pipeline, and the pressure sensor BP201' is also connected to the cylinder gas supply opening port; the exhaust port of the solenoid valve BD201' is connected to the cylinder gas supply opening vent port; the pressure gauge P_N35' and the safety valve AF101' are connected to the solenoid valve BD201' and the manual valve JF13' through the gas collection pipe. Among them, the solenoid valve DF1' connected to the long-term purging air supply port is normally open; the cylinder supplying air opens the solenoid valve BD201'; the cylinder releasing air closes the solenoid valve BD201'.

[0003] However, the existing gas distribution station's gas supply line has a solenoid valve DF1' that is continuously energized and supplies gas, and it lacks redundant opening or closing functions. Since the existing gas distribution station's gas supply line only has one solenoid valve for closing, the gas supply will be interrupted when the solenoid valve fails. Utility Model Content
