Conventionally, field workers open and close the water valve, but there is no information to know the opening degree (opening rate), so the operation is performed by referring to the data sheet that lists the number of opening and closing rotations by valve diameter and model. There was a problem that the current opening status could not be accurately grasped.

In addition, if problems that are difficult to determine visually, such as water leakage, poor flange connection, packing detachment, etc. occur in the water regulating valve itself, it is not only difficult to determine whether such problems have occurred, but even if such problems occur, it is difficult to determine whether or not a problem has occurred. There were difficulties.

Conventional Korean Patent Registration No. 10-0902540 (registered on June 5, 2009) discloses a water control valve capable of detecting the flow of running water inside the valve.

However, this water control valve simply detects the flow of water inside the valve, and it is impossible to determine what kind of problem has occurred in the flow of the corresponding water. It is the same, but there is a problem that it is difficult to check the situation when the pressure change occurs due to the change in the amount of running water, so it can be confirmed that the invention does not improve the problems occurring in the existing water valve.
