摘要： A one piece double membrane diaphragm is disclosed. The double membrane diaphragm has an upper (308) and lower diaphragm membrane (310) joined together by a central section (312). The upper diaphragm membrane (308) is configured to seal against a top sealing surface (222) when the diaphragm is in a first position. The lower diaphragm membrane (310) is configured to seal against a bottom sealing surface (224) when the diaphragm is in a second position. An upper rim (318) may be attached to the upper diaphragm membrane (308) where the upper rim (318) is configured to hold the upper diaphragm membrane (308) into the valve. A lower rim (320) may be attached to the lower diaphragm membrane (310) where the lower rim (320) is configured to hold the lower diaphragm membrane (320) into the valve. The diaphragm may also be made from a resilient material and shaped ia such a way as to create a spring force holding the diaphragm into a default position in the valve.
摘要翻译：公开了一片双膜隔膜。双膜隔膜具有通过中心部分（312）连接在一起的上部（308）和下部隔膜（310）。当隔膜处于第一位置时，上隔膜（308）构造成密封顶部密封表面（222）。当隔膜处于第二位置时，下隔膜（310）构造成密封底部密封表面（224）。上边缘（318）可以附接到上隔膜（308），其中上边缘（318）构造成将上隔膜（308）保持在阀中。下边缘（320）可以附接到下隔膜（310），其中下边缘（320）构造成将下隔膜（320）保持在阀中。隔膜还可以由弹性材料制成并且成形为使得产生将隔膜保持在阀中的默认位置的弹簧力。

摘要： A safety valve for compressed air-operated consumers, including a valve housing having bores, and two direction control valves connected in parallel, each of the control valves having a working piston and a valve head connected to the piston. Two pilot control valves are operatively connected to the directional control valves so that each of the direction control valves is switchable by one of the pilot control valves. Each of the two valve heads is guided in a respective one of the bores in the valve housing. The housing has two cross-channels arranged to connect crosswise to each other. A first one of the pilot valves has a valve seat connected via a first pilot channel in the housing to one of the cross-channels which proceeds from the bore of one of the valve heads. A second of the pilot valves has a valve seat connected via a second pilot channel to another of the cross-channels which proceeds from the bore of another of the valve heads. A compressed-air switching element is provided between two corresponding points at each of the two directional control valves so that the safety valve can be blocked when pressures at the two points are different and turned back on again only by external compressed air-operated actuation of at least one of the two switching elements.
摘要翻译：一种用于压缩空气操作的使用者的安全阀，包括具有孔的阀壳和并联连接的两个方向控制阀，每个控制阀具有连接到活塞的工作活塞和阀头。两个先导控制阀可操作地连接到方向控制阀，使得每个方向控制阀可由一个先导控制阀切换。两个阀头中的每一个在阀壳体中的孔中的相应一个中被引导。壳体具有布置成彼此交叉连接的两个交叉通道。先导阀中的第一个具有经由壳体中的第一引导通道连接到从一个阀头的孔进入的一个交叉通道的阀座。第二个先导阀具有经由第二引导通道连接到从另一个阀头的孔进入的另一个交叉通道的阀座。压缩空气开关元件设置在两个方向控制阀中的每一个处的两个对应点之间，使得当两个点处的压力不同并且仅通过外部压缩空气操作致动而再次返回时可以阻止安全阀两个开关元件中的至少一个。
