The operation of will be described. First, the knob 23 is operated to rotate the gear 19, and the valve plate 12 is slid along the guide plate 13 via the rack 18 meshing with the gear 19 so that the valve hole 16
Stops the valve plate 12 at a position that coincides with the opening 14 of the guide plate 13. In this way, a perforator is attached to the outlet 4 in a state where the valve hole 16 and the opening 14 communicate with the outlet 4 of the saddle 2, and the water distribution port 29 (see FIG. 1) is bored in the pipe wall of the water distribution pipe 1. Before the drilling work is completed and the drilling machine is removed, the knob 23 is operated to rotate the gear 19 in the opposite direction to remove the valve plate 1.
By sliding 2 in the opposite direction to the front, the opening 14 of the guide plate 13 is closed by the valve plate 12, and the outlet 4 and the water diversion port 29 are shut off. At this time, the flexible valve plate 12 is pressed against the guide plate 13 by the water pressure and is brought into close contact therewith to stop the water from the water diversion port 25. In this state, the punching machine is removed, and a water supply pipe (not shown) is connected to the outlet 4 directly or through a joint. In addition, a connection screw portion 30 is provided at the outlet 4 in order to connect the punching machine and the water supply pipe. After connecting the water supply pipe, operate the knob 23 to open the valve plate 1
When 2 is slid and the valve hole 16 is brought into line with the opening 14 again, the outlet 4 and the water diversion port 25 are brought into communication with each other to allow water to pass therethrough. Since the flexible valve plate 12 and the guide plate 13 are smooth and in close contact with each other, there is no risk of water leakage through the gap between the plates 12 and 13. Even if it partially leaks, there is no problem in practical use because it is in the closed space 9.

Since a flat on-off valve mechanism is incorporated inside the saddle that is installed on the outer surface of the fluid mains (water distribution pipe), the overall structure can be made compact, and head loss is reduced by direct branch connection to the outlet provided in the saddle. it can. Further, the direct branching eliminates the need for a water diversion tap as in the past, which is economically advantageous. Furthermore, the number of connecting points of the branch pipe is small, and it is possible to reduce the cause of water leakage.
