2. Description of the Related Art FIG. 5 and FIG. 6 are piping explanatory views showing a relationship between a conventional drainage pipe from a water supply section of a house and a sewage pipe connected to sewer. That is, in the prior art, the tip of the drain pipe H connected to the water supply of the house and extended to the outside is led out as it is into the sewage basin M as shown in FIG. Alternatively, as shown in FIG. 6, an elbow-joint E bent downward at a right angle was connected to the tip of the drainage pipe H and led out into the wastewater basin M. S is a connecting pipe connecting the sewage basin to the sewer. Even when the drainage pipe H is directly led to the sewage without passing through the wastewater basin M, the situation at the tip opening of the drainage pipe H is the same as above. However, in such a case, since the tip end opening of the drainage pipe H is always left open in the wastewater basin M, sewage odors and insects from the sewer and sewage are
There is a great possibility that the water will penetrate the drainage pipe H that is open when water is not drained and enter the water supply area of the house. Further, when the sewage basin M overflows due to a typhoon or heavy rain, the sewage may flow back to the water supply section of the house via the drain pipe H. Therefore, an S-shaped bent pipe is interposed between the drainage port of the water supply part of the house and the drainage pipe H so that water can be stored therein and an attempt is made to eliminate the fear. ,
Although such a means is effective in preventing the matter accidentally dropped to the drain from flowing out to the sewer, it does not block the drain pipe H and the sewer or the sewer, so that it can prevent the infiltration of sewage odors and insects. Had no effect. In addition, it may lead to a situation in which sewage odors are filled into the room through the water supply section and insects intrude into the room, so that daily life with unsanitary and unpleasant feelings is sometimes forced. was there.

In the outlet end of the drainage pipe to the sewage basin or the like, the joint portion of the pipe in the switchgear of the above structure is fitted and connected. Therefore, at normal times (when not draining), the outlet end of the drainage pipe to the sewage basin is closed by the opening / closing lid that closes the inclined opening surface of the pipe end that connects to the drainage pipe, and shuts off from the sewage basin and sewage. Has been done. When the water is drained from the water supply area of the house, the drainage flows down the drainage pipe to reach a sewage basin, etc., and the water pressure corresponding to the amount of water pushes the lid open diagonally upward, and the lid opens and closes with the pipe. It opens by turning the fitting part as a fulcrum by turning it counterclockwise at an appropriate angle, and drainage is discharged to a sewage basin and sent to the sewer. When the drainage is completed, the water pressure due to the drainage is released, so the open / close lid rotates counterclockwise due to its own weight, and the flexible material such as the rubber plate on the back side closely contacts the inclined opening surface of the pipe. Then, this is closed, and the opening surface of the outlet end of the drainage pipe to the sewage basin is blocked from the sewage basin and the sewer.

The inclination angle of the inclined opening surface 3 at the tip of the pipe 1 may be an appropriate angle in principle, but in actual use, in the case of the oblique downward direction of 45 degrees as shown in the above embodiment. Is preferred. In this case, the magnitudes of the horizontal and vertical components of the rotational moment due to gravity acting diagonally downward from the center, which is the center of gravity of the opening / closing lid 4, are equal,
The opening and closing action of the opening and closing cover 4 using the drainage water pressure and the gravity of the opening and closing cover 4 is well balanced, the opening and closing cover 4 opens with an appropriate pressure, and the inclined opening surface 3 can be well closed. Because. By the way, when the inclination angle is smaller than 45 degrees, the magnitude of the force of the horizontal component of the rotary moment becomes smaller than that of the vertical component as it becomes smaller. Although the opening / closing lid 4 can be opened with a small pressure, at the same time, there is a tendency that the opening / closing lid 4 is relatively gradually lowered in terms of the goodness of maintaining the closure of the inclined opening surface 3. On the contrary, when the tilt angle is larger than 45 degrees, the magnitude of the force of the horizontal component becomes larger as compared with that of the vertical component, so that the inclined opening surface Although the goodness of maintaining the occlusion of 3 is gradually increased, there is a tendency that an excessively large pressure is required to open the opening / closing lid 4.
