Abstract

Система регулирования давления в гермокабине летательного аппарата, содержащая командный прибор, к выходу которого через повторители командного сигнала подсоединены два выпускных клапана, к управляющей полости которых параллельно повторителям командного сигнала подключены ограничители предельного избыточного давления, в сбросовую линию которых последовательно включены двухпозиционный электроклапан и ограничитель минимального абсолютного давления, а также реле давления со светосигнализатором "перенаддув" и источники постоянного напряжения, отличающаяся тем, что, с целью повышения эксплуатационной надежности системы при отказах ограничителей абсолютного давления, в нее дополнительно введены два реле и реле времени, при этом замыкающий контакт реле времени включен в цепь питания светосигнализатора, замыкающий контакт первого реле включен в цепь питания второго реле и двухпозиционных электроклапанов, замыкающий контакт второго реле включен параллельно замыкающему контакту первого реле, а обмотка реле времени подключена к обмотке реле давления.The pressure control system in the aircraft pressurized cabin, containing a command device, to the output of which two exhaust valves are connected through the repeaters of the command signal, limiting overpressure limiters are connected to the control cavity of which, in parallel, the two-position electrovalve and the minimum absolute limiter pressure, as well as a pressure relay with a "overcharge" flasher and sources of constant voltage, characterized in that, in order to improve the operational reliability of the system in case of failures of absolute pressure limiters, two relays and a time relay are added to it, the closing contact of the time relay is connected to the power supply circuit of the flasher, the closing contact of the first relay is connected to the power supply circuit of relay and two-position solenoid valves, the closing contact of the second relay is connected in parallel with the closing contact of the first relay, and the winding of the time relay is connected to the winding of the pressure relay.
