ができる。The water is supplied to the strainer 1 built in the pressure reducing valve 4.
5 → Similarly, the check valve 17 → the pressure reducing valve 4 → the water supply pipe 3 → the hot water storage tank 2 is supplied with water, and the water is branched from the water discharge pipe 12 and discharged. The water sent to the hot water storage tank 2 is heated by the heater 10 to become hot water, which is discharged from the hot water pipe 11. Activating the drain valve 16 allows the water so far to drain through it. When the relief valve 14 is operated,
The water or hot water so far can be discharged from the escape pipe 13. When water leaks from a part of the hot water storage tank 2 or the water supply pipe 3 or the like after the pressure reducing valve 4, the water falls and is collected by the water leak receiving tray 5. When the leak sensor 6 detects the collected leak,
The signal is sent to the controller 8, which drives the electric actuator 23 of the water stop device 7 to close the pressure reducing valve 4. That is, the electric motor 2 of the electric actuator 23
When the rod 9 is rotated, the rod 26 is rotated in the same direction by the detent part 30 and is screwed in the valve closing direction by the screw part 28. When the rod 26 is screwed forward, the valve rod 19 of the pressure reducing valve 4 is pushed in the valve closing direction, and the valve body 20 is closed. Pressure reducing valve 4
Is closed, water supply thereafter is stopped. When the water supply is stopped, the hot water from the hot water pipe 11 and the hot water pipe 1
Since the water from the nozzle 2 is not performed, the user requests a repair contractor for repair. During this time, the water supply is continuously stopped, so that the water leakage due to the water supply is eliminated and the vicinity is not flooded. After closing a water stopcock (not shown) connected to the upstream side of the water supply pipe 3,
The electric water heater 1 can be used by returning the water stop device 7 to its original state or replacing it with a new one. The electric actuator 23 of the water stopping device 7 does not need to open and close the pressure reducing valve 4 and only needs to operate the valve closing operation. Therefore, the structure is simplified and the cost can be reduced.

Is replaced with a cylinder 31 screwed to the valve box 18 instead of the lid (not shown) of the pressure reducing valve 4, a sealing member 32 interposed between the cylinder 31 and the valve box 18, and a cylinder 31. A rod 33 movably provided to push the valve rod 19 in the valve closing direction;
Sealing material 34 interposed between this and cylinder 31
The present embodiment is different from the first embodiment in that it comprises an electric heating cylinder 35 called thermowax provided on the cylinder 31 and pushing the rod 33 in the valve closing direction. Electric heating cylinder 35
Is composed of a cylinder, a piston, a piston rod, a thermal expansion body such as wax filled in a tail chamber, a heater provided in the tail chamber, and the like. In such a device, when the electric heating cylinder 35 is energized, the thermal expansion body is expanded by the heater, the piston rod is extended and moved through the piston, and the rod 33 is pushed in the valve closing direction. Therefore, the valve rod 19 is pushed in the valve closing direction, and the valve body 20 is closed.
Since such a device performs a linear motion, there is no need to provide a screw mechanism for converting a rotary motion into a linear motion as in the first embodiment, and the structure is simplified accordingly,
Cost can be reduced.
