絡され得るように設定される。BACKGROUND ART FIG. 6 and the conventional Y-shaped pipe joint for a vacuum sewer shown in FIG. 7 (hereinafter, simply "Y-shaped pipe joint" hereinafter) is 1,
As shown in FIG. 8 , a branch pipe 4 extending from a vacuum sewage valve tank 3 is connected to a vacuum main pipe 2 extending from a vacuum station (not shown). In the vacuum main 2,
As can be clearly understood from FIG. 9, the straight pipe portion 5 laid at a predetermined angle is connected by a lift portion 6 raised at a predetermined angle, and the Y-shaped joint 1 is connected to the straight pipe portion 5. Is inserted. The Y-joint 1 includes a main pipe 7 as shown in FIGS. 6 and 7, and an inflow pipe 8 is connected to the main pipe 7. The inflow pipe 8 is smaller than 90 degrees with respect to a vertical plane passing through the axis of the main pipe 7, for example, 45 degrees, in order to prevent drainage flowing into the main pipe 7 from the inflow pipe 8 from flowing back through the main pipe 7. The main pipe 7 is inclined at a predetermined angle θ (FIG. 7 ) with respect to a horizontal surface passing through the axis of the main pipe 7 in order to prevent the drainage from flowing backward through the inflow pipe 8. . The angle θ is set so that the main pipe 7 and the inflow pipe 8 (branch pipe 4) can always be communicated with air.

およびサドル形Ｙ字管継手を提供することである。In the conventional Y-shaped pipe joint 1, the drainage can be prevented from flowing backward through the inflow pipe 8, but when the value of the angle θ increases, the branch pipe 4 ( Figure
8 ) The position becomes too high, and there is a possibility that the inherent advantage of the vacuum sewage system that the piping can be laid shallowly may be offset. In addition, there is a problem that the workability is poor because it is necessary to maintain a three-dimensional connection angle. Accordingly, a main object of the present invention is to provide a Y-joint for vacuum sewage and a saddle-shaped Y-joint in which piping can be laid shallowly and workability can be improved.

In a Y-joint for sewage, a horizontal surface passing through an axis of a main pipe is made parallel to an axis of an inflow pipe, and a pipe of the inflow pipe is provided.
A Y-joint for vacuum sewage, characterized in that a top inner surface is disposed above a pipe top inner surface of a main pipe . The second invention includes an inflow pipe and a seat formed at an end of the inflow pipe and having an inner surface extending along an outer surface of the main pipe. When the seat is fixed to the main pipe, the axis of the inflow pipe is connected to the main pipe. In a saddle-shaped Y-shaped pipe joint for vacuum sewage inclined at an angle of less than 90 degrees with respect to a vertical plane passing through the axis of the pipe, when the seat is fixed to the main pipe, the axis of the inflow pipe is the axis of the main pipe while it is arranged parallel to the horizontal plane passing through the, Kan'itadaki inner surface of the inlet tube
