The present invention provides a device for closing an air discharge hole of a water pipe and a method for closing an air discharge hole of a water pipe. According to the present invention, an air discharge hole formed in a water pipe is firstly converted into a shape capable of screw connection, and the water pipe is secondarily stably closed by the screw connection. A manifold connection device represented as a spray device connected to the water pipe is removed. Even if water pressure supplied to the water pipe is suddenly and instantaneously changed, the device for closing an air discharge hole maintains the water pressure to be safe. According to the present invention, the device for closing an air discharge hole of a water pipe can be used by being assembled with four components as a simple device which is not complicated. So, the device for closing an air discharge hole of a water pipe enables workers to easily use the same. |
