The invention discloses a check valve. Magnets which are magnetically attracted with each other are correspondingly fixed to the periphery of a partition plate and a partition plate mounting cover of the check valve, the partition plate droops under the gravity of the partition plate to cover a through hole, the partition plate and the partition plate mounting cover are in close contact through magnetic attraction between the magnets, so that the partition plate tightly covers the through hole in the partition plate mounting cover, and odor and peculiar smell of a sewer can be effectively blocked. The effect can further be achieved by combining magnet adsorption and steel balls, namely on the basis that the magnets which are magnetically attracted with each other are correspondingly fixed to the periphery of the partition plate and the partition plate mounting cover, the steel balls are fixed to the lower part of the partition plate, and the weight of the lower part of the partition plate is increased through the steel balls, so that the gravity center of the partition plate shifts downwards; the lower part of the partition plate is more tightly contacted with the partition plate mounting cover when the partition plate freely droops, so that the separation effect of the partition plate is better than that of the partition plate adopting a single magnetic attraction mode; and the problem that a partition plate of an existing check valve cannot tightly block odor and peculiar smell of a sewer is solved.
本发明公开了一种止回阀，其隔板周缘、隔板安装盖分别对应固定有相互磁吸的磁石，隔板在自身重力下下垂遮盖通孔，隔板与隔板安装盖之间通过磁石之间的磁力吸附实现紧密接触，使得隔板严实地遮盖隔板安装盖上的通孔对下水道臭气、异味起到更有效地阻隔作用；也可以采用磁石吸附与钢珠结合的方式来达到上述效果，即在隔板周缘、隔板安装盖分别对应固定相互磁吸的磁石的基础上，再在隔板下部固定钢珠，利用钢珠来加重隔板下部重量，使隔板的重心向下偏移，使隔板在自由下垂时其下部更紧密接触隔板安装盖，这种结合方式能使隔板比采用单一的磁吸方式阻隔效果更好；解决了现有止回阀的隔板对下水道臭气、异味阻隔不严密的问题。
