  "textContent": "The present invention discloses a sealing drain valve arrangement that is to be opened by rotation and comprises a sealing valve housing and a drain valve, which each have a circular cross-section. The sealing valve housing encloses the drain valve, and the drain valve is capable of rotating within the sealing valve housing. On the bottom side of the sealing valve housing, a centrally arranged second drain opening and an associated internal recess are formed, whose inner side wall has an unequal distance to the second drain opening. At the upper end of the drain valve, an eccentrically arranged first drain opening is formed, which has a radial distance to the second drain opening that is greater than the minimum distance between the inner side wall of the recess and the second drain opening and less than the maximum distance between the inner side wall of the recess and the second drain opening. According to the invention, the venting of air is advantageously achieved independently of the production of a seal through a change in position between the sealing valve housing and the drain valve. For sealing, no additional tool is required to control the drain switch.",
