  In such a sprinkler fire extinguishing equipment 10, equipment having an inner diameter suitable for the fire extinguishing performance is selected for the piping system from the fire extinguishing pump 14 to the sprinkler head 30 and the equipment provided in the pipe.

  FIG. 2 is an explanatory view showing an embodiment of a water flow detection device as a water-based fire extinguishing equipment of the present invention on the front and side. In FIG. 2, the flowing water detector 28 has a primary flange 36 formed on the lower side of the main body 34 constituting the valve box and a secondary flange 38 formed on the upper side, and the main body 34 is opened by flowing water. The valve body which operates is stored.

  A flowing water detection unit 40 is provided on the left side of the main body 34. When the valve body built in the main body 34 is opened, the flowing water detection switch is operated in conjunction with this to output a flowing water detection signal to the outside.
