Abstract

Выпускной исполнительный клапан системы регулирования давления воздуха в гермокабине летательного аппарата, содержащий корпус, в котором установлен подпружиненный запорный орган, закрепленный на эластичной мембране, разделяющей полость корпуса на надмембранную полость и подмембранную полость, сообщенную с гермокабиной и атмосферой, пироклапан, в корпусе которого размещен пирозаряд, перепускной клапан и выполнены канал сброса с дюзой на выходе и каналы подачи управляющей среды, сообщающиеся с надмембранной полостью, а также канал, сообщающий надмембранную полость с камерой сгорания пирозаряда, отличающийся тем, что, с целью повышения надежности клапана в работе за счет обеспечения дополнительного автономного принудительного открытия и отмены принудительных перемещений перепускного клапана, пироклапан дополнительно снабжен двумя пирозарядами и цилиндрической камерой с размещенным внутри нее поршнем, перепускной клапан выполнен в виде золотника с двумя кольцевыми проточками, установленного в корпусе с образованием его торцовыми концами относительно корпуса полостей, одна из которых сообщена через канал с камерой сгорания пирозаряда, а другая - с камерой сгорания одного из дополнительных пирозарядов, торцовый конец золотника, обращенный к цилиндрической камере, жестко связан со штоком поршня, при этом полость камеры сообщена с камерой сгорания второго дополнительного пирозаряда, причем надмембранная полость сообщена в нейтральном положении золотника через кольцевые проточки с каналами подачи управляющей среды и сброса, а в крайних положениях - или с камерой сгорания пирозаряда, или через обратный клапан и эжектор - с камерой сгорания первого дополнительного пирозаряда.The exhaust valve of the system for regulating the air pressure in the pressurized cabin of an aircraft, comprising a housing in which a spring-loaded shut-off member is mounted, mounted on an elastic membrane dividing the housing cavity into the supermembrane cavity and submembrane cavity communicated with the pressurized cabin and the atmosphere, pyro valve, in which the pyrocharged , a relief valve and a discharge channel with an outlet nozzle and control medium supply channels communicating with a supermembrane cavity, as well as a channel with communicating the supermembrane cavity with a pyrocharging combustion chamber, characterized in that, in order to increase the reliability of the valve by providing additional autonomous forced opening and canceling of the forced movements of the bypass valve, the pyro valve is additionally equipped with two pyrocharges and a cylindrical chamber with a piston inside it, the bypass valve made in the form of a spool with two annular grooves installed in the housing with the formation of its end ends relative to the housing along The other end, one of which communicates through the channel with the combustion chamber of the pyrocharge, and the other with the combustion chamber of one of the additional pyrochargers, the end end of the spool facing the cylindrical chamber is rigidly connected to the piston rod, while the cavity of the chamber communicates with the combustion chamber of the second additional pyrocharging , with the supramembrane cavity communicated in the neutral position of the spool through the annular grooves with the channels for supplying the control medium and discharge, and in extreme positions either with the pyrozaryad combustion chamber or through the Tny valve and ejector - with the combustion chamber of the first additional pyrocharge.
