The invention relates to an overpressure vent system for an aircraft fuel tank. An overpressure discharge (OPV) system (150) for a fuel tank (102) of an aircraft (800) is provided. The OPV system (150) includes an OPV valve (152) configured to be coupled in fluid communication with a supply line (104) of a nitrogen-rich air distribution system, NEADS (100), such that the OPV valve (152) is configured to discharge pressure from the supply line (104). The OPV valve (152) is configured to be coupled in fluid communication with the supply line (104) upstream of the outlet (136) of the supply line (104), and the NEADS (100) delivers nitrogen-rich gas from the outlet (136) to the fuel tank (102). The OPV valve (152) is configured to sense a pressure within the supply line (104) upstream of the outlet (136) of the supply line (104).

    本发明涉及飞行器燃料箱的超压排放系统。提供了一种用于飞行器(800)的燃料箱(102)的超压排放(OPV)系统(150)。OPV系统(150)包括OPV阀(152),OPV阀(152)被配置为与富氮空气分配系统即NEADS(100)的供应管线(104)流体连通地联接,使得OPV阀(152)被配置为从供应管线(104)排放压力。OPV阀(152)被配置为在供应管线(104)的出口(136)上游与供应管线(104)流体连通地联接,NEADS(100)将富氮气体从出口(136)输送到燃料箱(102)。OPV阀(152)被配置为感测在供应管线(104)的出口(136)上游的供应管线(104)内的压力。
