Since the present invention is constructed as described above, the valve body is screwed into the valve stem threading hole formed in the valve opening part using a drill of a drilling machine installed on the defective water sprinkling nozzle on the road surface, and the water sprinkling hole in the base body is screwed. This is a method of regenerating a defective water spray nozzle by regenerating the defective water spray nozzle by blocking it and causing water to be sprayed through the water spray hole of the valve body.

Since the valve body used for this regeneration has a valve mechanism, the amount of water to be sprayed can be adjusted.

The valve mechanism rotates the valve stem relative to the valve cylinder, moves up and down,
The amount of water sprinkled can be adjusted accurately by raising and lowering the screw valve stem, which has excellent features such as helping to conserve water.
