Abstract
The utility model discloses an urban sewer check valve and an urban sewer mouth. The check valve is a rubber check valve. A water outlet part of the check valve comprises a transition part and a transverse I-shaped water outlet; the inner surfaces of the transverse I-shaped water outlet are adhered with each other; and the upper end of the transverse I-shaped water outlet is connected with a mounting part through the wedged transition part. The check valve of the utility model is arranged below a well cover of a shaft well so as to separate a drain hole of the well cover from the lower part of the shaft. The transverse I-shaped water outlet of the check valve can stop odor in a sewer, prevent pests in the sewer from flying out or climbing out through the sewer and improve the environment and hygienic quality nearby the sewer. The rubber check valve has good elasticity, so when rainwater or sewage enters the sewer mouth, water pressure can open the transverse I-shaped water outlet through the wedged transition part; and after the rainwater or the sewage passes through the sewer mouth, by means of the elasticity of the rubber, the transverse I-shaped water outlet can be automatically closed to reinstatement. The urban sewer check valve has a simple structure and can be massively produced for popularization and application.
