Embodiment Construction

[0025] The structure of the city sewer mouth in embodiment 1 of the present invention is as Figure 1 to Figure 6 shown. The sewer mouth includes a shaft 1 with a rectangular mouth and a rectangular well cover 2. The well cover 2 is installed on the step at the top of the shaft 1. The grid-shaped well cover 2 has many sinkholes 201 for entering water into the shaft. The rubber check valve 3 is installed in the shaft, under the well cover, and separates the well cover drain hole from the bottom of the shaft. The rubber check valve 3 includes an installation part and a water outlet part, the installation part is on the top, and the water outlet part is on the bottom. The water outlet part includes a transition part and an inline water outlet 301, and the inner surfaces of the inline water outlet 301 are attached to each other to form a seal. The upper end of the inline water outlet 301 is connected to the installation part through a wedge-shaped transition part. The transitio...

Abstract

The invention discloses an urban sewer check valve and a sewer opening. The check valve is a rubber check valve. The water outlet part of the check valve comprises a transition part and a straight water outlet, wherein the inner surfaces of the straight water outlet are mutually attached; and the upper end of the straight water outlet is connected with a mounting part by the wedge-shaped transition part. The check valve is arranged under a well cover of a vertical well; and a water drop hole of the well cover is partitioned from the lower part of the vertical well. The straight water outlet ofthe check valve can block odor in a sewer, prevent pests in the sewer from flying or climbing by the sewer opening and improve the environment and the hygienic quality near the sewer opening. The rubber check valve has higher elasticity; when rain or sewage enters the sewer opening, the pressure of water enables the straight water outlet to be opened by the wedge-shaped transition part; and afterthe rain or the sewage passes, the straight water outlet can be automatically closed and recovered to the original state by the elasticity of the rubber. The invention is simple in structure and convenient for mass production, generalization and use.

Description

[technical field] [0001] The invention relates to a city drainage device, in particular to a city sewer check valve and a city sewer mouth. [Background technique] [0002] Sewers are urban public facilities, and sewer systems are used to collect domestic wastewater and industrial wastewater facilities. The sewer mouths of city squares and roads are mainly used to collect and discharge sewage and rainwater. Climbing out greatly increases the possibility of spreading disease and also deteriorates the environment near the sewer mouth. [Content of the invention] [0003] The technical problem to be solved by the present invention is to provide a sewer check valve with simple structure, smooth drainage, and the ability to prevent the odor in the sewer from spreading out and pests flying or crawling out through the sewer mouth. [0004] Another technical problem to be solved by the present invention is to provide a sewer mouth that has a simple structure, smooth drainage, and ...
