The present invention relates to a sewage device having a sealing device that can be opened and closed, and more particularly, a body portion and a cover portion coupled to the guide means of the body portion can maintain the water seal when the drainage is used, and the drainage hole when the drainage is not used. It is related with the sewage apparatus provided with the opening and closing sealing device which can be closed.

Generally, the sealing device refers to a device that is installed to be buried together with a sewer pipe on the bottom surface of a bathroom, a utility room, a chemical factory sewer, and discharges various sewage into the sewage pipe, and at the same time, blocks the odor flowing back from the sewer pipe. The top of the sealing device is generally provided with a cover, such as a filter perforated with a plurality of drain holes serves to filter foreign matter contained in the sewage.

1 is a perspective view showing a water-sealing device according to the prior art used for the above uses, Figure 2 is a longitudinal cross-sectional view of the water-sealing device shown in FIG. 1 and 2, the water sealing device 100 according to the related art is formed of a cylindrical body of a predetermined length and is provided with a locking protrusion 111 on an upper portion of the body 110 so as to be installed in an inlet state in a drain pipe not shown. To be seated in the drain. In addition, a plurality of inlets 124 are formed on the upper surface of the body 110 to allow sewage into the water sealing device 100, and the inlets extend to the inlets 121, which are pipes of a predetermined length. A discharge port 131 is provided on the lower surface of the inlet 121 so as to cross the inlet 121. The upper surface of the outlet 131 is formed higher than the lower surface of the inlet 121 to maintain the water of a certain height as shown by the dotted line in FIG.

The body 110 is provided with a seating portion 113 on the upper surface on which the inlet 124 is formed, and installs a strainer 120 on the seating portion 113 to remove foreign substances contained in the sewage. When the sealing device 100 is installed as above and the sewage flows into the inlet 124, the sewage flows downward along the inlet 121 and filled up to the height of the outlet 131 as shown by the arrow in FIG. 2, and then drains. Inflow to the upper portion of the 131 is discharged to the outside.

Therefore, the sewage up to the height of the discharge port 131 stays in the body 110, and odors and the like that rise through the discharge port 131 may not be introduced into the inlet 121 by the sewage remaining in the body 110.
