VALVE WITH VALVE AND VALVE COMPRISING A VALVE AND AN AIRCRAFT COMPRISING SUCH A VALVE

摘要

The invention relates mainly to a flap valve and a valve comprising a valve as well as to an aircraft comprising such a valve. /P P The invention relates to a valve 1 comprising a valve 2 on its surface. Valve 1 is used for (fine) pressure or flow regulation, valve 2 for pressure safety balancing. The incorporation of the valve 2 in the valve 1 or of the valve 1 in the valve 2 makes it possible to make only one opening in the separation surface and thus to reduce the weight and the price and to increase the safety. / P P The device according to the present invention applies to any device for regulating pressure and / or flow rate between an enclosure and the outside or between two enclosures comprising a safety balancing device. / P P The invention applies in particular to aircraft construction, to the construction of petroleum refineries, of fluid distribution devices and of chemical reactors.
