摘要： The invention provides a sealable lead-through system for a protected space defined by walls, the system including at least one sleeve (6,6',8) made of a flexible material, one end of the sleeve (6,6',8) being tightly attached to the outside of one of the walls, at least one sealing element (10,18,20), approximately fitting the sleeve (6,6',8) and being made of a material deformable in compression, the sealing element (10,18,20) being provided with a bore approximately fitting the size of a transfer member intended to be led from outside the protected space into its interior or vice-versa , the sealing element (10,18,20) being adapted to be subjected to a compressive force, for sealing off any interspaces between the transfer member and the bore, and between the sealing element and the sleeve.

摘要： The invention provides a flap valve for controlling the air pressure within a protected space defined by walls, the flap valve having a valve flap, articulated at least indirectly to the surface of one of the walls and being subjectable to both a sealing force which forces the valve flap against a valve seat surrounding an opening in the wall surface and to an opening force which lifts the flap off the valve seat. The flap valve has a first position in which the protected space is sealed off from a contaminated environment, and a second position in which air from the protected space is allowed to escape into the environment via the opening, wherein the sealing force is a magnetic attraction between a portion of the surface of the valve flap and the valve seat. A method for controlling the air pressure within a protected space is also provided.

摘要翻译：用于控制由壁限定的受保护空间内的空气压力的瓣阀具有间隙地间接连接到其中一个壁的表面的阀瓣，并且可以同时受到将阀瓣压靠在围绕在壁表面开口，并将打开的力提升到阀座上。用于控制由壁（2）限定的受保护空间内的空气压力的瓣阀包括间接地连接到其中一个壁的表面的阀瓣（12），并且能够受到迫使阀瓣的密封力抵靠围绕壁表面中的开口的阀座以及将阀瓣从阀座提升的打开力。所述瓣阀具有第一位置，在所述第一位置中所述受保护空间与受污染环境密封，并且第二位置使得来自所述受保护空间的空气经由所述开口逃逸到所述环境中。密封力是阀瓣表面的一部分与阀座之间的磁吸引力。
