Leak detection device for double-wall pipeline systems and container systems |
摘要 |
A leak detection device for double-wall pipeline or container systems has a leak detector with a vacuum pump, a pressure-dependent switch for the vacuum pump, and an alarm device. The leak detector monitors simultaneously several containers. A collecting main is connected to the vacuum pump and by vacuum lines to the containers. Each container has a vacuum connector connected to a control space of the container. The control spaces are parallel connected to the leak detector. Each vacuum line has a first liquid lock arranged at the vacuum connector so as to block liquid that has leaked into the vacuum lines from a leaky container from penetrating into the control spaces of the leak-free containers. A second liquid lock is arranged in the collecting main to prevent liquid from entering the vacuum pump. A measuring line taps the collecting main and is connected to the leak detector.
