Description

[Detailed Description of the Invention] [Objective of the Invention] (Industrial Field of Application) The present invention relates to a pipe trap device, which is installed to prevent odor from a sewer pipe from leaking to a public area. The attachment involves a trap device formed in the tube.

(Prior art) In this type of conventional installation for connecting public squares or first squares to sewer wood pipes, the pipe bodies are connected in a substantially straight line. There was a problem that the odor from the pipe flowed from the pipe body to the side of the cell, and the odor leaked from the gap in the cell cover.

For this reason, as described in Japanese Utility Model Publication No. 54-20476, a structure has been proposed in which a streamer-like deodorizing band is provided at the outlet of a sewage basin or the like.

(Problem that the invention sought to solve) In the above-mentioned conventional structure provided with an odor-proofing band, the odor-proofing band opens when sewage flows out, and the tip of the odor-proofing band closes when sewage does not flow out, preventing backflow of odor. Since this odor-proof band is molded from vinyl resin, it is not durable, resulting in the problem that the odor-proof band must be replaced frequently.

The present invention has been made in view of the above-mentioned problems, and relates to a trap device for a drain pipe that is installed so that odor from the sewer main pipe side does not flow out to the drain side due to the shape of the pipe body.

[Structure of the invention]

(Means for Solving the Problems) The one-wrap device for installing pipes of the present invention connects one end on the upstream side to the main body side directly or through a connecting pipe, and the other end on the downstream side directly to the main pipe side. Alternatively, for installation that connects via a connecting pipe, the first curved part that curves the pipe body in an upward arc, and this first
The second curved part is continuous with the curved part and is curved downward, forming a substantially S-shape.

(Function) The pipe trap device of the present invention is installed by connecting one end of the pipe to the body side directly or via a connecting pipe, and connecting the other end to the sewage pipe side directly or via a connecting pipe. do. Then, the pipe body is removed from the water sealing line connecting the upper inner circumference of the first curved section and the lower inner circumference of the second curved section. It is sealed so that bad odors will not leak to the outside.

(Example) The configuration of an embodiment of the present invention will be described with reference to the drawings.

1 is attached to a tubular body, and this attached tubular body 1 is connected to a first curved tube member 3 to the right of a first curved portion 2 curved upward in an arc shape, and is continuous with this first curved tube member 3. It curved downward! ! It is composed of a second curved pipe member 5 having a second curved part 4 on the end side, and the ends of the first curved pipe member 3 and the second curved pipe member 5 are inserted 1 inch inside. They are connected by a connecting short pipe 6 and formed into a substantially S-shape. The curve angle θ of the curved portion 2.4 of the first and second curved pipe members 3, 5 is 60 @ or 606 or more, and this installation is performed on the pipe body 1.
A horizontal 1.1 water line connecting the straight line 7 connecting both ends of the line 7 and the upper inner circumference of the curved part 2 of the first curved pipe member 3 and the lower inner side of the curved part 4 of the second curved pipe member 5 The nexus angle α with 8 is 369
Or below 36°. A water seal mark line 9 is formed on the outer circumferential side surface of this takeaway tube body 1.

Further, in this attachment, a universal joint 10 is connected to the end of the first curved pipe member 3 of the pipe body 1.

Then, as shown in FIG.
The universal joint 10 connected to the end of the first curved pipe member 3 with 19 horizontal is connected to the public square or the first square 11, and the end of the second curved pipe member 5 is connected to the connecting pipe. 13 to the sewer main 12.

Next, the operation of this embodiment will be explained.

The sewage that has flowed into the mass body 11 is discharged from the attached pipe body 1 to the sewage main pipe 12. Then, the liquid accumulated below from the horizontal water seal line connecting the upper inner circumference of the curved part 2 of the first curved pipe member 3 and the lower inner side of the curved part 4 of the second curved pipe member 5 is caused to flow into the sewage pipe. The period from the pipe 12 to the interval 11 is sealed with water.

Further, as shown in FIG. 3, a connecting pipe 13 may be interposed on the body 11 side, and the universal joint 10 may be connected to both ends of the tubular body 1, and the mounting may be performed on the tubular body 1. The universal joint 10 may be connected only to one end.

In the above embodiment, the first curved pipe member 3 of the drain pipe body 1 was connected to the box body 11 side, but the first curved pipe member 3 was connected to the sewage main pipe 12 side, and the second curved pipe member 3 The curved pipe member 5 can also be connected to the square body 11 side.

Further, in the above-mentioned installation, the depth of the water seal becomes deeper by increasing the length of the connecting short pipe 6 that connects the ends of the first curved pipe member 3 and the second curved pipe member 5 of the pipe body 1.

〔Effect of the invention〕

According to the present invention, for example, when connecting a public sewer pipe to a public sewer pipe, a trap can be formed in the pipe body, and odors from the sewer main pipe will not leak to the sewer pipe, and the structure is simple and cleaning is easy. It is possible to use it and it is a factor that determines its durability.
