Interface valve for vacuum sewer systems |
摘要 |
A pinch-type interface valve for vacuum sewer systems. The interface valve includes a valve chamber and therein a tube-like elastic element. The elastic element has a lateral seal section with seal strips. The seal strips are pressed against each other and tightened when the elastic element is axially compressed. The elastic element is expanded and the seal strips are pulled from each other when vacuum is transmitted into the valve chamber. |
