Abstract

Перекрывное устройство, в проточном канале которого установлен входной обтекатель с расположенным в нем запорным органом, перекрывающим своим днищем проточный канал и образующим с обтекателем управляющую полость, сообщенную через дроссель с входным каналом и через управляющий клапан с атмосферой, причем в днище запорного органа выполнено отверстие, перекрытое подпружиненным чувствительным к выходному давлению вспомогательным подпружиненным клапаном, отличающееся тем, что, с целью повышения надежности работы, вспомогательный клапан расположен в управляющей полости и в ней установлен подпружиненный упор, воздействующий на вспомогательный клапан в конце открытия запорного органа.An overlapping device, in the flow channel of which an inlet fairing is installed with a stop valve located in it, blocking the flow channel with its bottom and forming a control cavity with the fairing, communicated through the throttle to the inlet channel and through the control valve with the atmosphere, an auxiliary spring-loaded valve blocked by a spring-loaded output-pressure sensitive, characterized in that, in order to increase the reliability of operation, the auxiliary valve It is located in the control cavity and has a spring-loaded stop, acting on the auxiliary valve at the end of the opening of the closure member.
