Summary:The utility model relates to a sewer floor drain with a one-way isolation door, which comprises a floor drain casing and a filtering grate, wherein the filtering grate is installed at the upper part of the inside of the floor drain casing, and a downwards arc-shaped outlet cavity is arranged below the floor drain casing. A lateral water outlet is arranged on the outlet cavity, and a one-way isolated door is hinged on the outlet cavity. Due to the adoption of a new design scheme, the volume of the floor drain is decreased and a drainage pipe is shortened. When water drainage is conducted, the running water is smooth, when the water drainage is not conducted, the one-way isolated door is sealed. Thus, the overflow of water and leakage of foreign odor in the sewer can be prevented. The utility model has the advantages of simple structure and convenient operation. A sewer opening needs no change, and the utility model can be directly installed in a general situation.
