Abstract
1. Система наддува нейтральным газом топливных баков летательного аппарата, содержащая источник нейтрального газа, соединенный с топливным баком расходной магистралью с установленными в ней перекрывным клапаном, регуляторами высокого и низкого давления и смесителем нейтрального газа с воздухом, подаваемым из воздушной магистрали, и продувочную линию, снабженную запорным клапаном, отличающаяся тем, что, с целью повышения экономичности и надежности в работе, воздушная магистраль снабжена запорным и перекрывным клапанами, первый из которых пневматически связан с реле, соединенным с расходной магистралью за регулятором высокого давления, и в расходной магистрали за регулятором высокого давления установлен перекрывной клапан, а перекрывные клапаны воздушной и расходной магистралей пневматически связаны с реле, соединенным с топливным баком через электромагнитный клапан, управляемый датчиком изменения скорости барометрического давления.2. Система по п.1, отличающаяся тем, что продувочная линия подключена к расходной магистрали за регулятором высокого давления и соединена с топливным баком через запорный клапан, управляемый пневмореле, и через регулятор низкого давления, установленный в расходной магистрали.1. The system of pressurization of neutral gas of the fuel tanks of an aircraft, containing a source of neutral gas, connected to the fuel tank by a supply line with a shut-off valve installed in it, high and low pressure regulators and a neutral gas mixer with air supplied from the air line and a purge line, equipped with a shut-off valve, characterized in that, in order to improve efficiency and reliability in operation, the air line is equipped with shut-off and shut-off valves, the first of which They are pneumatically connected to a relay connected to the supply line downstream of the high-pressure regulator, and a shut-off valve is installed in the supply line behind the high-pressure regulator, and the shutoff valves of the air and supply lines are pneumatically connected to the relay connected to the fuel tank via a change-solenoid valve barometric pressure velocity. A system according to claim 1, characterized in that the purge line is connected to the supply line downstream of the high-pressure regulator and connected to the fuel tank via a shut-off valve controlled by a pneumorel and through a low-pressure regulator installed in the supply line.
