Separator and method for sepatating valve and assembling and disassenbling apparatus used therein}

The present invention relates to a dewatering valve separating device and a dewatering valve separating method and a decanter used in the same. More specifically, the dividing valve used for valve replacement of the water supply pipe can be easily separated while easily shielding the connection pipe. It is about making it possible.

In general, the water pipe is composed of a large diameter main pipe for transporting a large amount of water over a long distance, and branch pipes used for relatively short distance transportation to supply water to buildings such as homes and offices branched from the main pipe. In this way, a large diameter main pipe or branched pipe body must be provided with a valve so that constant water can be interrupted, so that the work can be easily performed by the number of steps when replacing an old water pipe or replacing a valve.

In addition, since the operation is performed after all the valves installed around the replacement point are shut off in order to singly supply the constant water supplied to the water supply pipe or the valve at the replacement point, the range of the singular is wide.

In this regard, Korean Patent No. 10-0784884 discloses a "valve replacement device for a water supply pipe" and replaces a valve without reducing the number of stages when replacing a valve installed at a branch of a water supply pipe.
