    • PROBLEM TO BE SOLVED: To provide a device for solving a problem that vents are sequentially opened to release a predetermined overpressure condition in a protected space, but those vents are left opened and accordingly allow the confined space to continuously access ambient air.SOLUTION: A vent device 30 includes: a vent unit 62 positioned over a vent aperture in relationship normally closing the vent aperture; a vent structure including a movable pressure relief portion defined by a low strength line of the vent unit and including an initial closing position for covering the vent aperture, the pressure relief portion being movable to an open position extending apart from the vent aperture when a predetermined overpressure in the confined space passes through the vent aperture and is applied to the pressure relief portion of the vent unit; and a backstop 86. The pressure relief portion has a sufficient modulus of resilience and elastic coefficient to cause the pressure relief portion to return to the initial position from the open position upon relief of the overpressure condition, thereby solving the problem.
    • 要解决的问题:提供一种用于解决通风口被顺序打开以释放受保护空间中的预定超压状态的问题的装置,但是这些通风口被打开,因此允许限制空间连续地接近环境空气。 排气装置30包括:通常关闭通气孔的关系,定位在通气口上方的通气单元62; 排气结构,其包括由所述排气单元的低强度线限定的可移动的压力释放部分,并且包括用于覆盖所述通气孔的初始关闭位置,所述压力释放部分可移动到从所述通气孔延伸的打开位置, 在密闭空间内的超压通过通气孔,并被施加到通气单元的减压部分; 止回部86.压力释放部具有足够的回弹性和弹性系数弹性模量,从而在释压超压状态时使压力释放部从打开位置返回初始位置,从而解决了该问题。 版权所有(C)2012,JPO&INPIT
