A water-inflow prevention device is provided by installing a closing lidfor blocking a ductof an air pressure regulating valve, which regulates air pressure inside a cabin. A buoyant bodyis attached to the disc-shaped closing lidinstalled to the ductso as to be rotatable around a rotation shaft. The buoyant bodyreceives a buoyant force from water when immersed in the water. Since the side of the closing lidin which the buoyant bodyis attached is thereby floated in the water, the closing lidautomatically rotates around the rotation shaftso as to close a ventilation port

Water-inflow prevention device of aircraft, air pressure regulating valve for aircraft, and aircraft

The present invention provides a water inflow prevention device that prevents an inflow of water into an aircraft when the aircraft lands in water through a communication passage allowing the inside and outside of the aircraft to communicate with each other. The water inflow prevention device includes a mesh part provided in the communication passage, through the mesh part a fluid flowing through the communication passage passes.

Water inflow prevention device for aircraft working when landing in water, pressure adjusting valve, and aircraft

The present invention provides a water inflow prevention device for aircraft, working when landing in water, the device including: a blocking body for blocking a flow channel from an outside of the aircraft when landing in water, the flow channel allowing the inside and outside of the aircraft to communicate with each other, and a valve element of a pressure adjusting valve being positioned in the flow channel; and a connection part that is deformed when landing in water, wherein the blocking body is supported by a member constituting an end of the flow channel on a side outside the aircraft through the connection part, and the connection part is deformed in a direction so as to block the flow channel by the blocking body, with use of force of water acting on the blocking body when landing in water.
