模块分离设备
摘要：
一种气流分离设备，包括可从开放条件移动到关闭条件的气流分离阀门。在一个实施方案中的模块分离阀门包括当模块分离阀门处于开放条件时与气流流体连通的安全隔膜。当预定压差出现时，安全隔膜破裂，引起分离阀门关闭。在一个实施方案中，阀门与安全隔膜机械地连接以维持当安全隔膜完好的时候阀门处于开放条件，其允许阀门在安全隔膜破裂时移动入关闭条件。在另一个实施方案中，可挤压部件维持阀门处于开放条件，一旦安全隔膜破裂，流经阀门的气流压缩该可挤压部件以关闭分离阀门。
摘要（英）：

A gas flow isolation device includes a gas flow isolation valve movable from an opened condition to a closed condition. The module isolation valve in one embodiment includes a rupture disk in flow communication with a flow of gas when the module isolation valve is in an opened condition. The rupture disk ruptures when a predetermined pressure differential occurs across it causing the isolation valve to close. In one embodiment the valve is mechanically linked to the rupture disk to maintain the valve in an opened condition when the rupture disk is intact, and which permits the valve to move into a closed condition when the rupture disk ruptures. In another embodiment a crushable member maintains the valve in an open condition, and the flow of gas passed the valve upon rupturing of the rupture disk compresses the crushable member to close the isolation valve.
