A drain valve for an aircraft cabin door area, the drain valve comprising a valve body formed with a drain passage and a movement passage therethrough; the valve element is located in the movement channel of the valve body, the valve element is provided with a valve element through hole and can move between an opening position and a closing position in the valve body, and the drainage channel and the movement channel intersect at an angle. The valve core is connected with the sleeve piston, so that the valve core and the sleeve piston move together, the sleeve piston seals one end of the movement channel through the sealing ring and can move relative to the end, and in the opening position, the valve core through hole is communicated with the movement channel to allow drainage of the drainage valve, and in the closing position, the valve core through hole is staggered from the movement channel to allow drainage of the drainage valve. Therefore, drainage of the drainage valve is prevented.

    一种排水阀,用于飞机客舱门区域,该排水阀包括阀体,该阀体形成有穿过其的排水通道和运动通道;阀芯,该阀芯位于阀体的运动通道中,阀芯具有阀芯通孔,并且能够在阀体内在打开位置与关闭位置之间运动,其中,排水通道与运动通道成角度地相交。阀芯联接于套筒活塞,以使阀芯与套筒活塞一起运动,套筒活塞经由密封圈密封运动通道的一端并且能够相对于这一端运动,并且其中,在打开位置,阀芯通孔与运动通道连通,以允许排水阀的排水,而在关闭位置,阀芯通孔与运动通道错位,以阻止排水阀的排水。
