    • The present invention relates to a valve device (1) for a ventilation installation. The valve device (1) comprises a vent surface (4) that is equipped with a plurality of vent apertures (5) and a slide valve (6) comprising a slide valve plate (7) equipped with a plurality of slide valve apertures (8). The valve plate formed such that it can be varied between taking a first position (I) at which the vent apertures (5) are covered by the slide valve plate (7), and taking a second position (II) at which at least some vent apertures (5) have surfaces that overlap with some slide valve apertures (8) such that an air flow is permitted through the valve device (1). The valve device (1) is designed such that when the slide valve plate (7) is positioned on that side of the vent surface (4) that normally has a relatively higher pressure, the high pressure side (9), than the other side, the low pressure side (10). The slide valve plate (7) is formed such that the force from the pressure difference between the high pressure side (9) and the low pressure side (10) is sufficient to retain the slide valve plate in its place at the vent surface (4) when it is in the first, closed position (I).
    • 本发明涉及一种用于通风装置的阀装置(1)。 阀装置(1)包括排气表面(4),其配备有多个通气孔(5)和滑阀(6),滑阀包括装有多个滑阀孔(8)的滑阀板 )。 阀板形成为使得其可以在取出通气孔(5)被滑阀板(7)覆盖的第一位置(I)和取第二位置(II)之间变化,在第二位置(II)处至少一些 通气孔(5)具有与一些滑阀孔(8)重叠的表面,使得允许空气流通过阀装置(1)。 阀装置(1)被设计成使得当滑阀板(7)位于通常表面(4)的通常具有相对较高压力的一侧时,高压侧(9)比另一侧 ,低压侧(10)。 形成滑阀板(7),使得来自高压侧(9)和低压侧(10)之间的压力差的力足以将滑阀板保持在通风表面(4)的位置 )当它处于第一个闭合位置(I)时。
