Description

Prevention and smell prevention device of sewage pipes {Prevention apparatus of stink and noise from sewage pipe}

The present invention relates to a device that can effectively prevent the noise and odor generated in the sewage pipe that is installed in a general house or apartment or other buildings to perform the drainage function of sewage.

The noise generated from the sewer pipe refers to the noise generated by the drop of water when general water such as various sewage or rainwater comes down through the sewer pipe, and the smell refers to the odor generated from the sewer pipe.

Sewage pipes are typically installed in the interior of the building, so that when the sewage, cleaning water or rain water flows down, a lot of noise is generated, and the odor is emitted through the sewer pipe and emitted through the manhole.

In the structure of the conventional sewage pipe, when the water comes down by using a pipe of a predetermined standard, noise is generated by hitting the main wall of the pipe, and especially in a high-rise building such as an apartment, the drop of water becomes larger, and the noise is increased, especially in the lower floor. If you do, there is a problem that the noise is more severe.

The reason for the noise generated in the sewer pipe is that the sewer pipe is penetrated in a straight line, and the noise is severely generated due to the characteristics of the pipe.

In addition, the smell coming up through the sewer pipe is emitted into the room through the sewer in which water is introduced.

And even in the bathroom, the smell is emitted through the sewer installed on the floor of the bathroom.

As such, the noise generated while the water flows down and the odor generated from the sewer pipes cause a lot of discomfort.

The present invention installs an opening and closing plate that can be opened and closed by the load of water in the sewage pipe in a way to solve the above problems, and when the sewage does not flow, install a device having a function to close the inner diameter of the sewage pipe closely It is a technical problem of the present invention to prevent noise and smell at the same time.

The main body 10 in the form of a short pipe.

And a cover 33 that is covered on the top of the cylinder 12.

In the drawings, reference numeral 40 denotes a sewage pipe and 41 shows a connection member connecting the sewage pipe and the main body 10 of the apparatus of the present invention.

It demonstrates the effect of the present invention made of the above configuration.

The main body 10 of the apparatus of the present invention is mounted at a proper position as shown in FIG. 2, and in a state where water does not flow down, the elastic force of the coil spring 30 embedded in the cylinder 12 as shown in FIG. By this, the elastic opening and closing plate 20 is in a state of being in close contact with the bottom surface of the cylinder 12, and the outer diameter of the elastic opening and closing plate 20 is in a state of being in close contact with the inner diameter of the main body 10. .

When the water flowing down the sewage pipe is collected on the elastic opening and closing plate 20 and the load of water is applied to the elastic opening and closing plate 20, the elastic opening and closing plate 20 is bent downward as shown by the dotted line of FIG. 2. As the gap occurs between the outer diameter of the 20 and the inner surface of the main body 10, water flows down between the gaps, and the elastic opening and closing plate 20 is inclined so that water flows smoothly and the inclined surface of the elastic opening and closing plate 20 is formed. Since the water flowing down the water flows down the inner circumferential wall of the sewer pipe, there is no drop of water, so no noise is generated even when a large amount of water flows down, and a large amount of water falls on the elastic opening and closing plate 20 at once. Even if the opening and closing plate 20 is subjected to the load of the water to the buffer spring due to the elasticity of the spring 30 will greatly reduce the generation of noise.

And when the water does not flow down, the outer diameter of the elastic opening and closing plate 20 is in close contact with the inner diameter of the main body 10 to block the sewer pipe, so that the odor does not pass, so that the inflow of the odor is fundamentally prevented.

The present invention having the above-described configuration and action effect is very simple in its construction, and not only easy to manufacture, but also can be easily installed regardless of the sewage pipe specifications, since the standard of the main body 10 is manufactured to meet the standard of the sewer pipe. The water flows down the inner wall of the sewage pipe by the operation of the opening and closing plate to prevent the occurrence of noise and to prevent the inflow of odor by the blocking action by the opening and closing plate.
