The present invention relates to a non-return valve and a sewage treatment system using the same, in particular, the valve body is formed integrally with the branched first and second flow paths and is installed to prevent fluid flow in one direction at the end of the first flow path. Backflow prevention valve consisting of a first backflow prevention plate and a second backflow prevention plate installed to prevent one-way fluid flow from the front of the first backflow prevention plate to the second flow path, and water and odor returned by the sewage treatment system using the same. The present invention relates to a non-return valve and a sewage treatment system using the same so as to effectively block and prevent premature backflow of sewage due to saturation of the manhole.

In general, the flow of sewage in sewage pipes varies with time, and the flow of sewage in the fractionated sewage pipes varies depending on the amount of water used in general homes and businesses.

In addition, when there is little or no water usage, drainage facilities such as houses, buildings, and the like, washbasins, bathtubs, floor drains and the like, are empty or only a small amount of sewage flows.

At this time, the odor in the sewage pipe flows back to the sewer pipe and flows into the room through the floor drain hole in the building, and a reverse displacement is installed to prevent such phenomenon, and the reverse displacement is discharged from the sewage pipe with a return spring mounted on the hinge shaft. When the sewage flows into the stage, the sewage flows open by the height of the water, and when the sewage level is not formed, the valve body is in close contact with the valve body by the elastic spring.

However, the conventional sewer reverse displacement as described above opens and closes around the hinge regardless of whether the water level is high or low each time the sewage is drained, so that the damage speed is high and the airtightness is maintained according to the degree of damage. It was difficult and resulted in a shortening of the service life, and in case of small amount of sewage, it was caused when it could not be discharged due to the weight of the door.

In order to improve such a problem, the reverse odor countermeasure for preventing odor backflow of the sewage department is disclosed in Korean Utility Model Application No. 2000-21306, and its configuration is as shown in FIGS. 1A and 1B. ) And the hinge springs attached to the discharge end of the reverse variable body (7) in a hinged manner so that the return spring (5) is always pulled in the closed direction, and the reverse variable width gate (1) is made of flexible synthetic resin, The restoring elastic body (2) is embedded at the edge of the side door (1), and the cross section (8) of the reverse body (7) is configured to be downwardly gradient.

However, the valve as described above is installed in a state in which the reverse displacement gate 1 is exposed to the end of the reverse displacement main body 7, so that interference caused by external factors is frequently generated, which may cause malfunctions. In addition, the reverse gate door (1) is operated, there is a disadvantage that can not be easily moved when installed in the manhole due to the movement of the fluid.

In order to solve the above drawbacks, the object of the present invention is to prevent the inflow of odor and drainage in a timely manner, to effectively block the backflow of water and odors, the assumption of sewage due to saturation of the manhole To prevent backflow in advance and to provide a non-return valve and a sewage treatment system using the same to facilitate the treatment of rapidly flowing sewage.
