[0004] This is different from a sprinkler fire extinguishing system for buildings in which a closed sprinkler head is connected to a dedicated fire extinguishing pipe and running water is generated only when the sprinkler head operates. This is because, even if a running water detector is provided in the resulting water pipe, the running water detector malfunctions every time a faucet or the like is opened.

It is conceivable to provide a flow meter at each of the main valve side of the water supply pipe and the terminal side where the faucet or the like is provided, and determine whether or not the sprinkler head has operated based on the flow rate difference between the two. In this case, the structure is very complicated and expensive, and is not practical for residential use. Therefore, an object of the present invention is to provide a joint that can easily and reliably detect only flowing water due to the operation of a sprinkler head in a pipe.

Next, the operation will be described. When the faucet 5 is opened and running water is generated in the water supply pipe 2, or when the tap water is closed and the flow of water is stopped, a water pressure change occurs in the water supply pipe 2 and in the branch from the pipe 2 to the closed sprinkler head 8. The change in the water pressure acts on the blade 93 of the flowing water detector 9 to rotate the rotating shaft 92. But rotation axis 9
2 does not rotate due to the action of the torque spring 96, and the proximity switch 95 does not turn on.

FIG. 3 shows one embodiment of a joint 70 with a running water detection function in which the running water detector 9 is integrated into the fitting 7 (A).
Is a longitudinal sectional view, and (B) is a BB sectional view of (A). In FIG. 3, reference numeral 71 denotes a joint body; 72, a branch path to which the closed-type sprinkler head 8 is connected directly or via a pipe; 92, a rotating shaft provided through the side wall of the branch path 72; Reference numeral 93 denotes a blade plate which is attached to the rotating shaft 92 so as to be deviated similarly to FIG. When this blade plate 93 is biased so that the portion near the inlet 73 from the water pipe 2 is longer than the portion near the outlet 73 to the water pipe, the blade 93 rotates against pressure fluctuation due to flowing water in the normal water pipe 2. This is advantageous for suppressing operation. In addition, the joint 70 in which the running water detector 9 is integrated with the parts 94 to 97 which are the same as those in FIG. 2 operates the closed type sprinkler head 8,
When running water for sprinkling occurs, the branch path 72
In the same manner as described above, the flowing water detecting blade plate 93 provided therein rotates by the action of flowing water, and the proximity switch 95 is turned on to output an operation signal to the alarm device 10.

As described above, the present invention is configured as described above. Therefore, even if a water flow is generated in the pipe and the water flows from the inlet to the outlet of the joint body, the flowing water detector detects the flowing water. The sprinkler head connected to the branch path side operates, and the water detector operates only when water flows from the inflow port or the outlet port to the branch path section. It is possible to select and detect only flowing water by the operation of (1). Further, the blade plate is attached to the rotating shaft so as to be deflected so that a portion near the inflow port from the pipe is longer than a portion near the outflow port to the pipe.
For this reason, it is advantageous to suppress the rotation operation with respect to the pressure fluctuation due to the flowing water in the normal piping other than the operation of the sprinkler head. Further, since the flowing water detector is provided with the torque spring, it is possible to prevent rotation of the blade due to a change in water pressure caused by ordinary flowing water other than the sprinkler head in the pipe.
